A Registered Retirement Savings Plan (RRSP) is the primary Canadian tax-deferred retirement account. Contributions are deductible against income, growth is tax-deferred, withdrawals are taxed as income.
Quick answer. A Registered Retirement Savings Plan (RRSP) is the primary Canadian tax-deferred retirement account. Contributions are deductible against income, growth is tax-deferred, withdrawals are taxed as income.
Tax savings approximates the value of either (a) up-front deductions (Traditional / RRSP / FHSA) or (b) tax-free growth (Roth / TFSA / ISA) relative to a taxable account.
About this tool
The RRSP calculator projects the future value of contributions to a Registered Retirement Savings Plan, the primary Canadian tax deferred retirement account. Contributions are deductible against current income, growth is sheltered from tax until withdrawal, and every dollar pulled out (in retirement or earlier) is taxed as ordinary income in the year you take it.
For 2026 the deduction limit is the lesser of 18 percent of prior year earned income or 32,490 CAD, minus any pension adjustment if you participate in a workplace pension. Unused room carries forward forever, which lets late starters catch up. Two specialty windows borrow against the account without triggering tax: the Home Buyers Plan allows 60,000 CAD per spouse for a first home, and the Lifelong Learning Plan allows 20,000 CAD for full time education.
PMT = annual contribution, up to 32,490 CAD for 2026 plus carried forward room.
r = expected annual real return (typically 5 to 7 percent for a diversified portfolio).
n = years until withdrawal.
Current marginal rate = combined federal plus provincial rate on the top dollar of income.
Retirement marginal rate = expected combined rate during withdrawal years, often lower because earned income disappears.
Worked example
A 35 year old Ontario professional earning 180,000 CAD contributes 20,000 CAD per year to an RRSP for 30 years. Current marginal rate is 43.41 percent, expected retirement rate is 28 percent, and the portfolio earns a 5 percent real return:
Annual contribution: 20,000 CAD.
Immediate tax refund: 20,000 x 0.4341 = 8,682 CAD per year.
Growth of the annuity stream: 20,000 x ((1.05^30 - 1) / 0.05) = 1,328,981 CAD pre tax.
After tax retirement value (28 percent withdrawal rate): 1,328,981 x 0.72 = 956,866 CAD.
Bracket arbitrage value: (43.41 percent - 28 percent) x 20,000 = 3,082 CAD per year in real tax savings before any growth.
Result: The deduction during the high earning years and the lower withdrawal rate in retirement deliver about 956,866 CAD of after tax retirement spending power. If the saver expected a 43 percent withdrawal rate, the RRSP would essentially tie the TFSA on after tax dollars and lose on flexibility.

Common mistakes
Contributing in a low bracket year. A 27 percent deduction is wasted if your retirement bracket is 30 percent. Save the room and contribute in a higher income year, or use the TFSA instead.
Not carrying forward the deduction. Contribute now, claim the deduction in a future high earning year. The dollars grow tax sheltered immediately even before the deduction is taken.
Spousal contributions to the wrong account. A spousal RRSP shifts retirement income from the higher earner to the lower earner, only useful when bracket spreads will persist in retirement. Income splitting rules (after age 65) reduce the benefit.
Cashing out before retirement. Early withdrawals trigger withholding tax (10 to 30 percent) immediately plus full income inclusion at year end, often resulting in a 45 to 50 percent effective rate. Use HBP or LLP if you must touch the funds.
Leaving the deduction refund in cash. The tax refund from a 20,000 CAD contribution should be reinvested (often into the TFSA), otherwise the after tax math degrades and the TFSA looks better in hindsight.
Ignoring the pension adjustment. If you have a workplace pension, your effective RRSP room is your 18 percent limit minus the pension adjustment reported on your T4. Over contributing creates a 1 percent per month penalty beyond the 2,000 CAD buffer.
The 2026 RRSP deduction limit is the lesser of 18 percent of prior year earned income or 32,490 CAD, minus any pension adjustment, plus carried forward room from prior years. Unused room never expires.
Should I use RRSP or TFSA?+
Use the RRSP when your current marginal tax rate is higher than your expected retirement bracket, because the deduction saves more today than the withdrawal will cost. Use the TFSA when current rate is lower or equal. Most Canadian planners use both: TFSA for fixed contribution room, RRSP for high bracket deductions and the Home Buyers Plan.
What happens to my RRSP at age 71?+
By December 31 of the year you turn 71, the RRSP must be either (1) withdrawn in cash (fully taxable as income that year), (2) converted to a Registered Retirement Income Fund, or (3) used to buy a life annuity. The RRIF is the standard choice; minimum annual withdrawals start the next calendar year and rise with age.
How do RRSP contributions reduce my tax?+
Every contributed dollar reduces taxable income at your top marginal rate. A 20,000 CAD contribution at a 43 percent combined federal plus Ontario rate generates an 8,600 CAD refund. The refund only materializes if you actually claim the deduction on your return; unclaimed deductions carry forward indefinitely.
