Spousal Buyout Calculator

One of you keeps the home; the other is paid out their share. Enter the split from your separation agreement — a percentage or a dollar figure — and see both sides' shares, the cheque, and the new mortgage the staying spouse carries. The split comes from your agreement and your lawyers. We do the mortgage.

The house, the balance, and the split

What it would appraise at now — not what you paid for it.

Everything secured against the home that gets cleared.

Some agreements deduct notional selling costs before splitting. Many use $0 — whatever yours says.

How your agreement states the split

The split comes from your separation agreement and your lawyers — never from this tool. We do the arithmetic on what was decided.

$

Penalty, legal and appraisal costs — and on the conventional route, any other debts or amounts you're clearing, as long as the total stays under 80% of the value. On CMHC's insured route nothing extra can be added — see the note below. Estimate the penalty with the Mortgage Penalty calculator.

Fits under the standard 80% ceiling — a refinance can usually go to 80% of the home’s value ($680,000 here). This is the conventional route, where most buyouts land, and it works for insured and uninsured files alike. Whether the file works comes down to income.

Not just for spouses. Any co-owner can be bought out this way — CMHC’s own name for its program is “dissolution of relationship,” and it covers anyone on title: a parent buying out a child, siblings, friends, former partners. One boundary to know: at CMHC, the insured financing can cover only the departing owner’s share — nothing extra rolled in — while the private insurers can differ on that, and on who can buy out whom. And it isn’t a specialty product: every lender we’ve asked participates. Which insurer and lender your file lands with is a placement decision, and that’s our job. Confirmed with CMHC, February 2026; lender participation checked August 4, 2026.
The professionals rule: a lawyer for the legal advice, a mortgage broker for the mortgage, an accountant for the tax — and try not to make these decisions alone. This tool does honest arithmetic on the agreement you already have; it is not legal advice, and it can’t tell you what the split should be. The 80% ceiling is the standard federal refinance limit (Financial Consumer Agency of Canada — checked August 4, 2026); the insured equity buy-out route is sourced from insurer underwriting policy — treated as a purchase, up to 95% by program, with the real ceiling set by the federal minimum down payment (5% of the first $500,000 + 10% of the rest — so 95% holds to $500,000 and tapers to about 91.7% at $1,499,999), both parties on title, a purchase agreement, finalized separation agreement or court order, and a full appraisal (verified August 4, 2026; insured territory only — above $1,499,999 of value the insured route doesn’t exist and buyouts go conventional: 80% ceiling, no insurance premium, no price cap; the insured route adds a mortgage default insurance premium). Insurers differ on what that route can include — at CMHC it covers only the departing owner’s interest, no new funds for any other reason, while private insurers can differ (confirmed with CMHC, February 2026). Arithmetic verified by 103 automated checks, August 4, 2026.
What this calculator does that most don't
  • Takes the split exactly as your separation agreement states it — a percentage of the net equity OR an agreed dollar figure — and shows both sides to the dollar, instead of assuming 50/50
  • Prices the staying spouse's real next step: old balance + buyout cheque + any penalty and legal costs rolled in, checked against BOTH ceilings — the standard 80% refinance limit and the insured equity buy-out route (95% by program, trimmed by the federal minimum-down tiers above $500,000 — verified against insurer underwriting policy) — with the overshoot in dollars
  • Shows the payment twice — at your rate AND at the stress-test rate a lender actually tests one income against
  • Flags the states most tools hide: negative equity, and an agreed figure bigger than the equity that exists

Keeping the home is a program, not just arithmetic. How buyouts are structured, what a lender needs from the separation agreement, and the three funding lanes — insured program, conventional/B refinance, private bridge — are on the Divorce & Spousal Buyout Mortgages page.
