Pay less tax this year. Build your retirement savings.
A Registered Retirement Savings Plan turns today’s tax bill into tomorrow’s retirement. Work out exactly what you can contribute — and the estimated tax saving it could produce.
Figures on this page are verified against the CRA limits table.
What is an RRSP, and how does the room work?
An RRSP is a registered account where contributions are tax-deductible, investments grow tax-deferred, and you pay tax only when you withdraw — usually in retirement, when your income is lower.
Your contribution room for 2026 is 18% of your 2025 earned income, up to a maximum of $33,810. That figure is reduced by any pension adjustment, and increased by unused room carried forward from previous years. The dollar maximum is a ceiling, not a target — most Canadians are limited by the 18% rule, not the cap.
Deduct it now
Contributions reduce your taxable income, which is where the tax saving comes from.
Grow it tax-deferred
No tax on growth inside the plan while it compounds. The tax is delayed, not cancelled, so money you take out in retirement is taxed as income that year.
Room never expires
Unused contribution room carries forward indefinitely.

This estimator runs entirely in your browser. The numbers you enter stay on your device — RESP Guru does not receive or store them. It uses the CRA 2026 RRSP dollar maximum of $33,810 and the 18%-of-prior-year-earned-income rule, less pension adjustment, plus carry-forward. The tax saving figure is a simplified estimate based on the marginal rate you select and doesn’t account for your full tax situation, credits, or clawbacks. Not financial or tax advice — your official deduction limit is on your CRA Notice of Assessment.

This page and its calculator are general information only — not financial, investment, insurance, or tax advice, and not a quote. RRSP contribution limits, the annual dollar maximum, and tax rules are set by the Government of Canada and may change; 2026 figures are per CRA and your official deduction limit appears on your Notice of Assessment. The tax saving estimate is simplified, based on a marginal rate you select, and does not reflect your full tax situation. Segregated fund investments are offered under an LLQP licence; other investment products may require a different licence and would be referred.
