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.

%
Debts cleared in the buyout

Joint cards, lines, loans — each with its own split of responsibility, because it often isn’t 50/50. The split comes from your agreement.

Room left under the 80% conventional ceiling right now: $60,000 — the most that can still be rolled in before the line.

A lump sum in the agreement

An equalization payment, support arrears — a one-time amount owed either way. “They” is the departing spouse.

$

Penalty, legal and appraisal costs — plus any other debts or amounts you're clearing: under 80% of value that's the conventional route, and past it the insured buy-out route can carry shared debts through the private insurers (CMHC's version is equity-only). The tool shows the room left under each ceiling. Estimate the penalty with the Mortgage Penalty calculator.

Against the home’s value72.9%

Fits under the standard 80% ceiling — a refinance can usually go to 80% of the home’s value ($680,000 here), and there’s $60,000 of room left under that line. 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 take shared debts on qualifying files, and can differ 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; private-insurer debt treatment and lender participation confirmed 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 (confirmed with CMHC, February 2026), while the private insurers take shared debts on qualifying files (confirmed directly, August 4, 2026). Shared debts and lump sums come from the agreement too — each debt’s split nets out of the departing cheque, the balances ride into the mortgage (past 80%, through a private insurer), and an equalization or support-arrears lump moves the cheque dollar for dollar, in either direction. Debts and rolled-in costs are checked against both ceilings live — the tool shows the room left under the 80% line and the tiered insured ceiling, and past them it says what has to be settled outside the mortgage. Arithmetic verified by 180 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
