Formula & methodology

Formula used

new room = min(previous year's earned income × 18%, annual dollar limit) − pension adjustments
available room = new room + unused carry-forward room
tax savings = min(planned contribution, available room) × marginal tax rate

The calculator takes 18% of your previous year's earned income, capped at the CRA's annual dollar limit, subtracts any pension adjustments from an employer plan, adds your carried-forward unused room, then estimates the tax refund your planned contribution would generate at your marginal rate.

Step-by-step calculation

1. New room
18% of previous year's earned income, capped at the CRA annual dollar limit, minus pension adjustment and past-service pension adjustment.
2. Available room
New room plus unused carry-forward room from prior years, if included.
3. Deductible amount
The smaller of your planned contribution and total available room.
4. Tax savings
Deductible amount × your combined federal + provincial marginal tax rate at your current taxable income.

Limitations

Does not fetch your actual CRA-confirmed room — always verify against your Notice of Assessment before contributing, since this is a formula-based estimate.
Treats the current-year contribution field as an annual total regardless of the selected contribution frequency.

Help & FAQs

Frequently Asked Questions

Clear answers to common questions to help you use this calculator confidently.

How is RRSP contribution room calculated?

Tap to view the answer

New RRSP room equals 18% of your previous year's earned income, capped at the CRA annual dollar limit ($33,810 for 2026), minus any pension adjustment from an employer plan. Add unused room carried forward from prior years for your total available room.

Can I carry forward unused RRSP room?

Tap to view the answer

Yes. Unused RRSP contribution room carries forward indefinitely — there's no expiry. Check your CRA My Account or your latest Notice of Assessment to see your accumulated carry-forward room.

How does a pension adjustment reduce my RRSP room?

Tap to view the answer

If you belong to an employer pension plan, your Pension Adjustment (reported on your T4 slip) reduces your new RRSP room dollar-for-dollar, since your pension already provides tax-sheltered retirement savings. A Past Service Pension Adjustment does the same for retroactive pension credits.

What happens if I contribute more than my available room?

Tap to view the answer

Over-contributing above your available room (beyond a small $2,000 lifetime buffer) triggers a 1% per month CRA penalty on the excess. Always confirm your exact room on your Notice of Assessment before contributing near your limit.

Does my current income affect my RRSP room calculation?

Tap to view the answer

No — new room is based on your previous year's earned income, not your current year's income. Your current taxable income is used separately, only to estimate the tax savings your planned contribution would generate at your marginal rate.

Understanding RRSP Contribution Room

How room is calculated each year

New RRSP room each year is 18% of your previous year's earned income, capped at a dollar limit — $33,810 for 2026 — and then reduced by any pension adjustment from a workplace pension.

Earned income is a specific concept. It includes employment income, self-employment income net of expenses, net rental income, and taxable alimony received. It excludes investment income, capital gains, most pension income, and OAS or CPP payments. This is why a retiree living on investments generates no new RRSP room, and why a landlord's rental profit does generate it while their capital gains do not.

Carry-forward, and why your room may be large

Unused room carries forward indefinitely with no expiry. Someone who has worked for fifteen years and contributed little may have well over $100,000 of accumulated room available.

This is a genuine planning asset. It allows you to hold contributions until a high-income year — after a promotion, on receiving a bonus, or in the year you realise a large capital gain — and claim the deduction when it is worth the most. Your exact room appears on your notice of assessment and in CRA My Account. Always use that figure rather than calculating it yourself, because the pension adjustment is difficult to reconstruct and errors here are penalised.

The pension adjustment

If you belong to a registered pension plan at work, your RRSP room is reduced by a pension adjustment reported in box 52 of your T4. The idea is that people with generous workplace pensions should not also get full RRSP room.

For a defined-benefit plan the adjustment is calculated from the benefit you accrued that year, and it can be large enough to reduce new RRSP room to almost nothing. For a defined-contribution plan it is simply the total of employer and employee contributions. A past service pension adjustment can arise if your plan is improved retroactively, reducing room further. None of this is an error — it is the system working as designed.

Over-contributing, and the $2,000 buffer

There is a $2,000 lifetime over-contribution buffer for anyone 18 or older. Exceed your room by more than that and the penalty is 1% per month on the excess, charged for every month it remains in the account.

A $10,000 over-contribution therefore costs $100 every month until corrected — $1,200 a year, with no tax deduction to show for it. You must file form T1-OVP and pay the penalty. The buffer itself is not deductible, so deliberately carrying $2,000 extra achieves nothing except tax-sheltered growth on a small sum. The most common cause of over-contribution is forgetting that employer contributions to a group RRSP count against your room.

Deadlines and the first-60-days rule

Contributions made in the first 60 days of a calendar year can be deducted against either that year or the preceding one, which is why the RRSP deadline falls at the start of March rather than at year end.

This gives useful flexibility: you can see your actual income for the year before deciding how much to contribute against it. Contributions made after the deadline apply to the current year only. Remember also that you can contribute now and defer claiming the deduction to a later year — the money starts growing tax-sheltered immediately while the deduction waits for a year when your marginal rate is higher.

When to stop contributing

You can contribute until December 31 of the year you turn 71, after which the plan must be converted to a RRIF or an annuity. If you have earned income in the year you turn 71, that generates room for the following year, which you cannot use in your own plan — but you can use it for a spousal RRSP if your spouse is under 72.

There are also situations where contributing is the wrong move. If you expect to have a low retirement income and qualify for the Guaranteed Income Supplement, RRIF withdrawals will reduce GIS by 50 cents on the dollar, often exceeding the tax saved on the way in. For those households, a TFSA is usually the better home for savings.

Formula & methodology

Formula used

new room = min(previous year's earned income × 18%, annual dollar limit) − pension adjustments
available room = new room + unused carry-forward room

Step-by-step calculation

1. New room
18% of previous year's earned income, capped at the CRA annual dollar limit, minus pension adjustment and past-service pension adjustment.
2. Available room
New room plus unused carry-forward room from prior years, if included.
3. Deductible amount
The smaller of your planned contribution and total available room.
4. Tax savings
Deductible amount × your combined federal + provincial marginal tax rate at your current taxable income.
