Investment · CPP
CPP disability benefit estimator.
The real formula, straight from the Canada Pension Plan Act: a flat rate plus 75% of your own calculated CPP retirement pension — plus the contributory-eligibility rule most estimators skip entirely.
Your monthly disability pension is $610.46 (2026 flat rate) plus 75% of your calculated retirement pension, up to a maximum of $1,741.20/month. To qualify, you must be under 65, have a disability that's both severe and prolonged, and have contributed to CPP in 4 of the last 6 years — or 3 of the last 6 with 25+ years of contributions in total.

The formula, straight from the Act
Section 56(1) of the Canada Pension Plan Act defines the disability pension as a flat rate benefit plus 75% of the amount of the contributor's retirement pension. For 2026, the flat rate is $610.46/month. The 75% earnings-related portion is uncapped by itself, but the combined total tops out at the published 2026 maximum of $1,741.20/month — which is exactly what you get from $610.46 plus 75% of the 2026 maximum retirement pension ($1,507.65), confirming the two published figures are internally consistent.
The contributory requirement most people don't check
Meeting the disability test isn't enough on its own — Service Canada also requires a minimum recent contribution history: contributions in at least 4 of the last 6 years, OR at least 3 of the last 6 years combined with 25 or more years of total CPP contributions. Two provisions can extend that 6-year window (not modelled here): a child-rearing dropout for a parent who left paid work to raise young children, and a late-applicant provision for someone disabled before their contributory period technically lapsed.

Frequently asked questions
What if I don't know my "calculated retirement pension"?
It's the CPP retirement pension you'd be entitled to if you started collecting it today, based on your actual contribution history — not the same as your future pension at 65 (which would usually be higher). Check your Service Canada My Account or use our CPP & OAS Calculator as an estimate.
Is the disability pension taxable?
Yes — like other CPP benefits, it's taxable income. The disabled contributor's child benefit is taxable to the CHILD, not the parent, which often means little or no tax is actually owed on it.
What happens at age 65?
A CPP disability pension automatically converts to a CPP retirement pension at 65 — normally at a lower amount, since the retirement pension has no flat-rate portion and isn't calculated the same way. If you become disabled after already collecting a retirement pension, you may instead qualify for the smaller Post-Retirement Disability Benefit (not modelled here).
Does QPP work the same way?
Quebec's QPP disability pension is structurally similar but not identical — it has its own flat rate, percentage and eligibility tests set by Retraite Québec. Not modelled here.
Estimate only — not a benefits determination
This calculates from the published CPP Act formula and current amounts and checks the headline contributory-eligibility rule. It does not model the child-rearing dropout or late-applicant provisions, the Post-Retirement Disability Benefit, or QPP. Confirm actual entitlement and eligibility with Service Canada.
