RRSP Contribution Room Calculator Canada

What the RRSP contribution room calculator does

An RRSP gives you a deduction for contributing, but only up to a limit personal to you. The calculator estimates that limit from your prior-year earned income, the statutory rate and dollar cap, any pension adjustment and any room carried forward. Contributing within your room secures the deduction; going beyond it can bring a penalty.

How this year’s room is built

New room is the lesser of 18% of last year’s earned income and the annual dollar limit, $33,810 for 2026. For most people the 18% applies; for high earners the cap takes over. On $80,000 of prior-year income, 18% is $14,400, well below the cap. On $250,000, 18% would be $45,000, so the room is the $33,810 cap.

The pension adjustment

If you are in a workplace pension or deferred profit-sharing plan, the value of the benefit you earned last year, your pension adjustment, is subtracted from your RRSP room. Someone with a generous defined-benefit pension can have very little RRSP room left, which is expected.

Carry-forward room

RRSP room does not expire. Unused room carries forward and adds to future years, so people who have not contributed for a while often have a lot banked. The calculator adds your carried-forward figure to this year’s room.

A worked example

With $80,000 of prior-year earned income, new room is $14,400. A $4,000 pension adjustment reduces it to $10,400, and $6,000 of carried-forward room brings the total to $16,400. The same income can give very different room depending on the pension adjustment and carry-forward, which is why the calculator asks for all three.

Is contribution room the same across provinces?

Yes. Room is set by federal rules, so the rate, cap and carry-forward work the same everywhere. Your province affects how much tax a deduction saves, not the room itself. Quebec residents claim the deduction on their provincial return as well, against the same federal room, and pension adjustments reduce room in every province.

Reading the estimate sensibly

Only certain kinds of income count as earned income for RRSP purposes, so use that figure rather than total income. Past over-contributions, Home Buyers’ Plan or Lifelong Learning Plan activity and earlier pension adjustments all feed into your official limit, so confirm the exact number before a large contribution.

When to use it

• Before contributing, to confirm you have room.
• At tax time, to plan a contribution that reduces this year’s taxable income.
• If you have a workplace pension, to see how the pension adjustment affects your room.
• After years without contributing, to gauge your carried-forward room.

Common mistakes to avoid

• Contributing beyond your room. Once you exceed the $2,000 buffer, the excess is charged 1% for every month it stays in the plan.
• Using total income instead of earned income, which overstates room.
• Forgetting to subtract the pension adjustment.

Confirming your room

Your exact deduction limit is on your latest notice of assessment and in CRA My Account. Your pension adjustment is in box 52 of your T4, and contributions are claimed on Schedule 7 with your return. The rate and dollar limit are set by the government and can change; the calculator uses maintained figures.
