Canadian RRSP Contribution Calculator (2026)

Last updated

Estimates this year's RRSP contribution room using the 2026 dollar limit ($33,810) and 18% earned-income rate, with adjustments for pension adjustment, prior-year carry-forward, and HBP/LLP repayments owing. Reports the maximum additional contribution before exceeding limits.

Inputs

Employment, self-employment, rental — line 1500 of T1. Used to compute this year's new room.

From your prior-year T4 box 52 if you have a workplace pension. Otherwise 0.

From your CRA My Account 'RRSP deduction limit' minus any contributions already deducted.

Includes any made in the first 60 days of this year that are being claimed for prior tax year.

From your Notice of Assessment if you've withdrawn under HBP or LLP. Otherwise 0.

This calculator estimates a Canadian's RRSP contribution room for 2026 using the standard CRA formula: 18% of prior-year earned income, capped at the $33,810 annual dollar limit, minus any pension adjustment, plus unused room from prior years, minus HBP/LLP repayments owing for the year.

The result includes the new room earned this year (whether limited by the dollar cap or by the 18% rate), the total room available including carry-forward, and the maximum additional contribution before exceeding the limit. The calculator surfaces the $2,000 lifetime over-contribution buffer rule and reminds the user to verify against their CRA My Account before contributing near the limit.

How this calculator works

Step 1 — New room earned this year.

new_room = MIN(prior_year_earned_income × 18%, $33,810) − pension_adjustment

Step 2 — Total room including carry-forward.

total_room = unused_room_from_prior_years + new_room − HBP/LLP_repayment_owing

Step 3 — Available to contribute now.

available = total_room − contributions_already_made_this_year

Worked example

Sarah earned $95,000 in 2025. No workplace pension (PA = $0). She has $12,000 in unused RRSP room carried forward from prior years and has not yet contributed in 2026.

  • 2025 earned income × 18%: 95,000 × 18% = $17,100
  • 2026 dollar limit: $33,810
  • New room (lesser): $17,100
  • Pension adjustment: $0
  • Carry-forward: $12,000
  • Total room available: $17,100 + $12,000 = $29,100
  • Contributions made this year: $0
  • Max additional contribution: $29,100

Compare to David who earned $250,000 in 2025 with a $9,000 pension adjustment from his workplace DB plan, and $25,000 in carry-forward:

  • 2025 earned income × 18%: 250,000 × 18% = $45,000
  • Limited at the dollar cap: $33,810
  • Less PA: $33,810 − $9,000 = $24,810 new room
  • Total room: $24,810 + $25,000 = $49,810

David's earned income is high enough that the dollar cap binds. His workplace DB pension adjustment removes a substantial portion of his new room. His carry-forward is the largest contributor to total available — common for high earners who have not maxed RRSP in prior years.

Frequently asked questions

What is the 2026 RRSP dollar limit?

The 2026 RRSP contribution dollar limit is $33,810. The contribution rate (18% of prior-year earned income) caps at this dollar amount — so anyone whose prior-year earned income is above $187,833 ($33,810 ÷ 18%) is limited by the dollar cap rather than the percentage rate.

What counts as 'earned income' for RRSP purposes?

Earned income for RRSP purposes is broader than salary alone but narrower than total income. It includes employment income, self-employment net income, taxable disability and CPP/QPP disability payments, royalties, rental income net of expenses, support payments received, and certain other items. It does NOT include investment income (dividends, interest, capital gains), most pension income, or government benefits like OAS or CCB. The figure is reported on line 1500 of your T1 General.

What is a pension adjustment (PA) and why does it reduce my room?

If you have a workplace defined-benefit (DB) or defined-contribution (DC) pension, the value of the pension benefits earned by your employer on your behalf is reported as a Pension Adjustment on your T4 box 52. The PA reduces your RRSP room by the amount the employer effectively contributed to your retirement on your behalf, on the principle that workplace-pensioned employees shouldn't be able to double up. If you have no workplace pension, your PA is $0.

Can I over-contribute?

The CRA permits a lifetime over-contribution buffer of $2,000 with no immediate penalty. The buffer counts against your future contribution room, so it's a forward-shift, not free room. Over-contributions ABOVE the $2,000 buffer attract a 1%-per-month penalty on the excess until withdrawn, plus the over-contributed amount is not deductible. Many Canadians rely on the buffer to make full contributions early in the year before final earned-income data is available.

What about contributions made in the first 60 days of the next year?

Contributions made in the first 60 days of a calendar year (Jan 1 to ~Mar 1) can be claimed as a deduction either on the prior year's return or the current year's return — at the contributor's option. This is why CRA Notices of Assessment list 'unused contributions' separately from 'unused room' — contributions can sit in the account waiting to be deducted in a later year. The calculator's 'contributions already made this year' field should include first-60-day contributions IF you intend to claim them this year.

Should I check my CRA My Account before contributing?

Yes — always. This calculator estimates room from the inputs you provide, which is useful for planning. The authoritative number is on your CRA Notice of Assessment under 'RRSP deduction limit', updated yearly after you file. The CRA's RRSP/PRPP Deduction Limit Statement (My Account → 'RRSP and TFSA' → 'RRSP') reflects all reported earned income, PAs, prior contributions, and HBP/LLP repayments. If you're contributing close to the limit, never rely on a calculator estimate alone.

What about the spousal RRSP?

Spousal RRSP contributions count against the CONTRIBUTOR's contribution room, not the spouse's. So if you contribute $10,000 to a spousal RRSP, $10,000 of YOUR room is used (the spouse's room is unaffected). The deduction is also taken on YOUR return. The spousal RRSP is held in the spouse's name, and after a 3-calendar-year wait, withdrawals are taxed in the spouse's name — useful for income-splitting in retirement when one spouse expects to be in a lower tax bracket. This calculator computes the contributor's room only; the spousal-vs-individual decision is independent of the room calculation.
