Home Equity Access Calculator

1) Current mortgage & property

Estimated/Appraised property value ($)

Use a conservative number if you want a conservative answer.

Current mortgage balance ($)

This is what you owe today (not the original amount).

Current mortgage rate (annual %)

Used to estimate your current payment (if you don’t enter one).

Payment frequency

For Canadian mortgages, this calculator uses semi-annual compounding.

Annual gross household income ($) (optional — for GDS/TDS)

Used to estimate GDS and TDS qualification ratios. Leave blank to skip.

Monthly condo fees ($) (optional)

Half of condo fees count toward GDS. Enter 0 for non-condo properties.

Remaining amortization

Years

Months

Current payment (optional)

If blank, we estimate it using your balance, rate, remaining amortization, and payment frequency.

2) Choose your equity access option

Program / structure (max LTV)

Max loan-to-value (LTV) determines the most you can borrow against the property.

Your max LTV (%)

Enter the lender’s guideline (example: 87.5). This becomes the cap for the calculation.

This is an insured mortgage (CMHC applies)

Access method

“Equity take-out” is modeled like a mortgage increase (similar math to a refi).

How much equity do you want to access? ($)

This is the cash you want in your pocket (or paid out to a spouse, renovations, etc.).

New borrowing rate (annual %)

Used for refinance / equity take-out payment estimates.

3) Estimated costs

Appraisal ($)

Legal / closing ($)

Discharge / admin ($)

Other costs ($)

Prepayment penalty ($)

For mid-term breaks only. Use Allen's penalty calculators to estimate yours: allenehlert.com/mortgage-penalty-calculators

Note: Penalty is the biggest cost in most mid-term refinances. Include it for an accurate break-even.

Roll costs into the new mortgage (when applicable)

Keep remaining amortization

Planning tool only. Actual lender policy, appraisal outcomes, payout penalties, legal requirements, and underwriting conditions may change results.

Note: Payment estimates use Canadian semi-annual compounding (Interest Act). CMHC default insurance premiums are calculated automatically for insured programs. Provincial PST on the CMHC premium (ON / QC / MB / SK) is shown separately and cannot be rolled into the mortgage. Prepayment penalties can be entered in the costs section. GDS/TDS ratios use a $150/mo heat allowance and 1%/yr property tax estimate — actual figures vary. TDS shown equals GDS unless other monthly debts are included. This is a planning tool; actual lender decisions depend on underwriting, credit, and policy not captured here.
