The Move Up / Down Calculator is designed to give you a clear, side-by-side view of what it actually costs to move. Instead of guessing, it breaks down your current home sale, mortgage payoff, transaction costs, and new purchase into one cohesive financial picture—so you can see exactly where you stand.

Whether you are considering a bigger home for a growing family, your forever home, or maybe moving down to something more manageable in your later years, the Move Up / Down Calculator will help you decide if ‘making a move‘ makes sense for you and your situation.

1. Overview

The Move Up / Down Calculator goes beyond basic estimates by showing your net proceeds, total purchase requirements, cash needed (or surplus), and new mortgage payments—while also evaluating affordability using GDS/TDS ratios. Whether you’re upgrading, downsizing, or simply exploring your options, this tool helps you make a confident, informed decision based on real numbers—not assumptions

It covers four interconnected areas:

• The proceeds you can expect from selling your current home after paying off the mortgage and covering transaction costs.
• The total cost of buying your next home, including the purchase price, closing costs, and any mortgage default insurance.
• The net position from the move — specifically, how much cash you will have left over or how much new financing you will need.
• Your estimated monthly mortgage payment, total housing cost, and retirement timeline based on the new mortgage.

An optional Scenario Comparison panel lets you test two different purchase options side-by-side using the same sale proceeds.

2. Calculator Sections

The calculator is arranged as a series of stacked panels. Work through them from top to bottom for the most reliable results.

2.1 Your Current Home Sale

This panel calculates the money you will have available after selling your existing home. There are two sub-sections:

Home Details

Field	What to enter
Expected Sale Price	The price you realistically expect to achieve, not the list price. For planning purposes use a conservative estimate.
Realtor Commission (%)	Enter the total commission as a percentage of the sale price. The default is 5.00%. This should reflect the full amount paid to both listing and buyer agents.
Other Selling Costs	Staging, pre-sale repairs, cleaning, or any other costs paid out of pocket before closing. Leave at $0 if none.
Moving Costs	Your estimated cost to physically move to the new home. The default is $2,000. Adjust to reflect your actual situation.

Mortgage Costs

Field	What to enter
Current Mortgage Balance	The outstanding principal remaining on your current mortgage at the time of sale. If you are not sure, check your most recent mortgage statement.
Mortgage Penalty	If you are breaking your mortgage before the end of the term, your lender will charge a penalty. Leave at $0 if you are at the end of your term. Use the Mortgage Penalty Calculator link to estimate this amount.
Legal and Discharge	Legal fees and mortgage discharge costs on the sale side. The default is $1,500. Use the Mortgage Discharge Calculator link to refine this estimate.

Selling Summary

Once you enter your numbers, the Selling Summary shows:

• Proceeds From Sale of the Home — the equity left after paying off the mortgage and all transaction costs. This is the amount you will be able to put toward your next purchase.
• Total Transaction Costs — the sum of commission, other selling costs, moving costs, penalty, and legal fees. This does not include your remaining mortgage balance.

Note:  The proceeds figure will show $0 until you have entered an Expected Sale Price. This prevents misleading negative numbers from appearing while the form is partially filled in.

Warning:  If your mortgage balance is greater than your expected sale price, or if your selling costs are unusually high, the calculator will display a warning. Review your inputs before proceeding.

2.2 Your Next Home Purchase

This panel calculates the total cost of buying your next home. There are two sub-sections:

Purchase Details

Field	What to enter
Expected Purchase Price	The price you expect to pay for the next home. For move-up scenarios, this will be higher than your current home. For downsizing scenarios, it will typically be lower.
Mortgage Default Insurance Premium	If your down payment is less than 20% of the purchase price (loan-to-value greater than 80%), mortgage default insurance is mandatory in Canada. The premium ranges from 0.60% to 4.00% of the mortgage amount. Use the Default Insurance Calculator link to determine the correct amount. Important: this premium is added to your mortgage balance and financed over the amortization period — it is not a cash cost at closing.

Closing Costs

Field	What to enter
Closing Costs	All cash costs associated with purchasing the new home, including legal fees, land transfer tax (provincial and municipal where applicable), title insurance, adjustments, and any lender or broker fees. Use the Closing Cost Calculator link to estimate this accurately. Do not include the mortgage default insurance premium here as it is entered separately.
Estimated Bridge Financing Cost	If there is a gap between your current home’s closing date and your new home’s closing date, you may need bridge financing. This covers the interest on the bridge loan. Use the Bridge Financing Calculator link to estimate this amount. Leave at $0 if your closings are concurrent.

Note:  The Purchase Summary shows two totals: Total Cost to Buy This Home (purchase price plus all costs including insurance) and Purchase Costs Beyond Price (the additional costs on top of the purchase price). These are provided for transparency — only the cash-based costs affect your equity gap calculation.

2.3  Your Move Summary

This is the core output of the calculator. It combines the selling proceeds and buying costs to show your overall financial position after the move.

Metric	What it means
Money Left From Selling Your Home	Your net proceeds after paying off the mortgage and all selling costs.
Gross Equity Before Costs	Sale price minus mortgage balance, before any transaction costs are deducted.
What Your Next Home Will Really Cost	Purchase price plus closing costs and bridge financing (cash costs only).
One-Time Cost of Making the Move	The total friction cost of selling and buying — selling transaction costs plus cash buying costs.
Estimated New Mortgage Needed	If your buying costs exceed your sale proceeds, this is the financing gap, plus any mortgage default insurance premium that will be added to the mortgage.
Cash Left Over After Moving	If your sale proceeds exceed your buying costs, this is the surplus cash remaining after the move.

Money Flow Summary

Below the KPI cards, the Money Flow Summary presents the same information as a sequential waterfall:

• Expected Sale Price
• Less Remaining Mortgage
• Less Selling Costs
• = Money Left From Selling Your Home
• Expected Purchase Price (next home)
• Plus Buying Costs
• = What Your Next Home Will Really Cost
• Cash Left Over  OR  Estimated New Mortgage Needed

Decision Badge

The calculator assigns one of three decision badges based on the move’s financial profile:

Badge	Meaning
Cash-Releasing Move	Your sale proceeds more than cover the cost of buying the next home. You will have cash left over after the move.
Manageable With Financing	You will need some new financing, but the amount is modest relative to the purchase price.
Financing-Heavy Move	The financing gap is large relative to the purchase price. The move may still be possible, but deserves careful review before proceeding.

2.4  Mortgage Payment and Retirement Timeline

If the move requires new financing, this panel estimates the resulting monthly payment and how it fits with your retirement plans.

Payment Assumptions

Field	What to enter
Estimated Mortgage Rate (%)	The interest rate on the new mortgage. Use the rate you have been quoted or a reasonable planning rate. The default is 5.00%.
Amortization (Years)	The amortization period for the new mortgage. The default is 25 years. The maximum insured amortization in Canada is 25 years; uninsured mortgages may go up to 30 years.
Current Age	Your current age. Used to calculate the age at which the mortgage will be paid off.
Target Retirement Age	The age at which you plan to stop working. The calculator uses this to determine whether the mortgage extends into retirement.
Annual Property Taxes	The estimated annual property tax on the new home. This is used to calculate your total monthly housing cost (PITD).
Monthly Heating / Utilities	Your estimated monthly heating and utility cost for the new home.
Gross Annual Household Income	Optional. If entered, the calculator will compute your GDS and TDS ratios. Leave blank if you prefer not to include qualification estimates.

Payment Summary

The Payment Summary shows four key outputs:

• Estimated Monthly Mortgage Payment — calculated using Canadian semi-annual compounding (the standard for all Canadian mortgages).
• Estimated Total Monthly Housing Cost — mortgage payment plus monthly property tax and heating.
• Estimated Age When Mortgage-Free — your current age plus the amortization period.
• Retirement Timing — whether the mortgage is paid off before retirement, around retirement, or extends into retirement.

Age Timeline

A visual bar shows the relative positions of your current age, target retirement age, and mortgage-free age on a single timeline.

GDS and TDS Ratios (Optional)

If you enter a Gross Annual Household Income, the calculator displays your estimated Gross Debt Service (GDS) and Total Debt Service (TDS) ratios alongside pass/fail indicators based on OSFI B-20 guidelines:

• GDS ≤ 39%  —  monthly housing costs as a percentage of gross monthly income.
• TDS ≤ 44%  —  all monthly debt payments (including housing) as a percentage of gross monthly income.

You can also enter Other Monthly Debt Payments to include car loans, student loans, or other obligations in the TDS calculation.

Note:  GDS and TDS ratios are estimates only. Lenders apply their own policies and may use different income and debt figures. These ratios are a useful planning guide, not a qualification decision.

2.5  Scenario Comparison (Optional)

The Scenario Comparison panel lets you test a second purchase option against the same home sale. Enable it by clicking the Enable Compare Scenarios toggle.

Scenario A reflects exactly what you have entered in the main calculator above. Scenario B lets you enter a different purchase price, closing costs, bridge financing, mortgage rate, and amortization to see how the two options compare side by side.

The comparison displays:

• Money left from selling (same for both, since the sale does not change).
• Total cost to buy the next home.
• Estimated new mortgage needed.
• Cash left over after moving.
• Estimated monthly mortgage payment.
• Mortgage-free age.

The conclusion box at the bottom highlights which scenario looks stronger and quantifies the most meaningful difference.

3.  Using the Calculator as a Move-Up Buyer

A move-up buyer is someone who sells their current home and buys a larger or more expensive one. The primary financial question is whether the equity in the current home is sufficient to cover the gap between what you will spend and what you will receive, and whether the resulting mortgage payment is comfortable within your income and retirement timeline.

3.1  What to Expect

In a typical move-up scenario:

• Your new purchase price is higher than your current sale price.
• Your equity from the current home may only partially offset the new purchase, leaving a financing gap.
• You will likely need a new mortgage that is larger than your current one.
• The decision badge will often read Manageable With Financing or Financing-Heavy Move.

3.2  Step-by-Step

1.Start with the sale side. Enter your expected sale price, commission percentage, and any other selling costs. Enter your current mortgage balance, any penalty for early discharge, and the legal fees.

2. Review the Selling Summary. Note the Proceeds From Sale figure — this is the equity you have to work with. If it is lower than expected, consider whether your sale price estimate is realistic or whether your mortgage balance and costs are higher than you thought.

3. Move to the purchase side. Enter the price of the home you want to move up to. If your down payment will be less than 20% of the purchase price, use the Default Insurance Calculator to find the premium and enter it in the Mortgage Default Insurance Premium field. Enter your total closing costs and any bridge financing costs.

4. Review the Move Summary. Focus on two numbers: Estimated New Mortgage Needed and Cash Left Over After Moving. For a move-up buyer, Cash Left Over will often be zero and you will see an Estimated New Mortgage figure. This is the amount you will need to finance.

5. Move to the Payment and Retirement Timeline panel. Enter your mortgage rate, amortization, current age, retirement age, estimated property taxes, and heating costs. Review the monthly payment and total housing cost to confirm they are comfortable.

6. If you have entered a gross income, check your GDS and TDS ratios. If either exceeds the guideline, discuss with your mortgage agent whether a longer amortization, a lower purchase price, or additional income could bring the ratios within limits.

7. Use the Age Timeline to visualise whether you will be mortgage-free before or after your target retirement age. If the mortgage extends significantly into retirement, consider whether a shorter amortization or larger down payment changes the picture.

3.3  Move-Up Scenarios to Model

Consider using the Scenario Comparison panel to test:

• A target purchase price versus a stretch price — to see how much the payment increases for an incremental step up.
• A 25-year amortization versus a 30-year amortization — to see the monthly payment difference and the impact on your mortgage-free age.
• Two different homes with different closing cost structures — to see which leaves you with a better overall position.

3.4  Common Move-Up Pitfalls

Land Transfer Tax  Land transfer tax is one of the largest closing costs for move-up buyers and is easy to underestimate. In Ontario, a $900,000 purchase carries approximately $16,475 in provincial LTT, plus an additional Municipal Land Transfer Tax if purchasing in the City of Toronto. Always use the Closing Cost Calculator link to get an accurate figure.

Mortgage Penalty  If you are breaking a fixed-rate mortgage before the end of the term, the penalty can be substantial — sometimes $10,000 to $30,000 or more. Use the Mortgage Penalty Calculator link and enter the result in the Mortgage Penalty field before drawing any conclusions.

Bridge Financing  If your purchase closing date precedes your sale closing date, you will need bridge financing to cover the gap. The cost depends on the size of the bridge and the number of days. Use the Bridge Financing Calculator to estimate this and include it in your closing costs.

4.  Using the Calculator as a Move-Down (Downsizing) Buyer

A move-down buyer sells a larger or more expensive home and purchases a smaller or less expensive one. The primary financial question is how much cash will be freed up after the move, and whether the new purchase can be made mortgage-free or with a significantly smaller mortgage.

4.1  What to Expect

In a typical downsizing scenario:

• Your new purchase price is lower than your current sale price.
• After paying off your existing mortgage and covering transaction costs, you will likely have significant cash left over.
• You may be able to buy the next home outright without a mortgage, or with a very small one.
• The decision badge will typically read Cash-Releasing Move.

4.2  Step-by-Step

• Start with the sale side. Enter the expected sale price of the larger home you are selling, along with commission, selling costs, your remaining mortgage balance, any penalty, and legal fees. Pay particular attention to the mortgage balance — for long-time homeowners this may be low or zero.
• Review the Selling Summary. The Proceeds From Sale figure will often be large in a downsizing scenario, particularly if the home has appreciated significantly or the mortgage is nearly paid off. This is the equity you will redeploy.
• Move to the purchase side. Enter the price of the smaller or less expensive home. If your proceeds from the sale will cover the full purchase price and closing costs, the Mortgage Default Insurance Premium will be $0. Enter your closing costs for the new purchase.
• Review the Move Summary. In most downsizing cases you will see a positive Cash Left Over After Moving figure. This is the capital that will become available for other purposes — retirement savings, investments, debt repayment, or gifting to family.
• If a small mortgage is still required, move to the Payment and Retirement Timeline panel and confirm the payment is manageable. In many downsizing cases the payment will be very small or the mortgage will be paid off within a few years.
• Consider using the Age Timeline. Even if a small mortgage is needed, confirm that it will be fully paid off well before your target retirement age.

4.3  Move-Down Scenarios to Model

Consider using the Scenario Comparison panel to test:

• Two candidate properties at different price points — to see how much more cash is freed up by choosing the less expensive option.
• Buying outright versus keeping a small mortgage — some downsizers choose to retain a small mortgage and invest the additional cash. The calculator can show you the payment and payoff age for that smaller mortgage.
• The impact of a longer bridge financing period if your sale and purchase closings are not concurrent.

4.4  Common Downsizing Considerations

Cash management  The Cash Left Over After Moving figure shows the total capital freed up, but does not account for taxes or investment decisions. For clients receiving a large cash sum from a downsizing move, we recommend working with a financial planner to determine the best use of those funds.

Do not forget closing costs on the purchase side  Even when buying a less expensive home, closing costs are real. Land transfer tax, legal fees, title insurance, and adjustments are all payable in cash at closing. Entering $0 in the Closing Costs field will overstate the cash left over.

No mortgage default insurance on most downsizing purchases  If your proceeds from the sale cover more than 20% of the new purchase price — which is typical in most downsizing scenarios — mortgage default insurance is not required. Leave the Mortgage Default Insurance Premium field at $0.

5.  Helper Calculators

Throughout the calculator, you will find links to companion calculators. These open in a panel overlay so you can work out a specific number and then return to the main calculator to enter the result. The following helpers are available:

Helper	When to use it
Mortgage Penalty Calculator	Use when you are breaking a fixed-rate or variable-rate mortgage before the end of the term. Enter the result in the Mortgage Penalty field.
Mortgage Discharge Calculator	Use to estimate the legal and discharge fees associated with closing out your existing mortgage on the sale side.
Default Insurance Calculator	Use when the down payment on the new purchase is less than 20% of the purchase price. The calculator will determine the premium tier and the dollar amount to enter.
Closing Cost Calculator	Use to estimate all cash costs on the purchase side, including land transfer tax, legal fees, title insurance, adjustments, and lender fees.
Bridge Financing Calculator	Use when the sale and purchase closing dates do not align and bridge financing will be required.

6.  Tips for Accurate Results

• Use conservative estimates on both sides. An optimistic sale price and an underestimated purchase price will make any scenario look better than it is.
• Always complete the Closing Cost Calculator before entering a closing cost figure. Land transfer tax alone can be $15,000 to $40,000 on a mid-range Ontario property.
• Check the mortgage penalty early. If the penalty is large, it may change whether the move makes sense at all.
• Review the Age Timeline before drawing conclusions about the payment. A manageable monthly payment that extends fifteen years into retirement may deserve more scrutiny.
• Use the Scenario Comparison panel to stress-test assumptions. Testing a range of purchase prices takes only seconds and gives a much clearer picture of where the financial limits are.
• All figures are estimates. For a full qualification and final mortgage approval, a complete mortgage application must be submitted to a lender.

7.  Frequently Asked Questions

Why are Proceeds showing as $0 when I first open the calculator?

The Proceeds field displays $0 until you enter an Expected Sale Price. This prevents misleading negative figures from appearing while the mortgage balance and costs are entered before the sale price.

Why is the mortgage default insurance premium not reducing my cash left over?

In Canada, mortgage default insurance premiums are almost always added to the mortgage balance and amortized — they are not paid in cash at closing. The calculator correctly treats the premium as a financed cost that increases the new mortgage amount rather than reducing your available proceeds.

Why does the GDS/TDS section not appear?

The GDS and TDS ratios only appear when you enter a value in the Gross Annual Household Income field in the Payment Assumptions section. Leave it blank if you prefer to keep income information out of the calculator.

What is the difference between Total Transaction Costs and One-Time Cost of Making the Move?

Total Transaction Costs covers everything deducted from the sale price on the selling side (commission, other selling costs, moving costs, penalty, and legal fees). One-Time Cost of Making the Move adds the cash buying costs (closing costs and bridge financing, but not the mortgage default insurance premium since that is financed) to give a complete picture of the total friction cost of the move.

Can I use this calculator for an investment property?

The calculator is designed for primary residence moves. It does not account for capital gains tax, rental income offsets, or investment property mortgage rules. For investment property scenarios, please contact us directly.

How is the monthly payment calculated?

The payment is calculated using Canadian mortgage math: the nominal annual rate is compounded semi-annually (as required by the Interest Act), converted to an effective annual rate, and then converted to an equivalent monthly rate. This is the standard calculation used by all Canadian lenders.
