Calculate Your RRSP Growth & Tax Refund
How to Use This Calculator
- Enter your income from last year. Your RRSP deduction limit is based on your previous year’s earned income, so this year’s salary is not the right input. Use your most recent notice of assessment if you have it.
- Enter your planned RRSP contribution. The contribution limit is 18% of earned income, up to an annual maximum, minus any pension adjustment from a workplace plan.
- Set the number of years to grow. Longer horizons change the outcome far more than a slightly higher contribution, because of compounding.
- Enter an expected annual return. Use a realistic long-run figure for your asset mix — a balanced portfolio has historically returned roughly 5–7%. Try a low and a high figure rather than trusting one number.
- Enter your expected retirement tax rate. This is the whole point of an RRSP: you deduct at today’s rate and pay tax at your rate in retirement. If your retirement rate is lower, you come out ahead.
- Read the tax refund figure. That is your contribution multiplied by your marginal rate — money you get back now and pay tax on later.
- Check the retirement withdrawal analysis to see what the accumulated balance would pay you, and how much tax would apply on withdrawal.
Understanding RRSPs
A Registered Retirement Savings Plan (RRSP) is a tax-deferred savings account where contributions reduce your taxable income in the year they're made. Unlike TFSAs, growth inside an RRSP is tax-sheltered but withdrawals are taxed as income. RRSPs are designed to reward savers who have higher income now but expect lower income in retirement.
How Your RRSP Contribution Reduces Tax
When you contribute to an RRSP, that amount is tax-deductible. If you earn $95,000 and contribute $10,000 to an RRSP, you report only $85,000 as taxable income. At a marginal tax rate of 43.4%, you immediately save $4,340 in taxes. This is the famous "tax refund" that makes RRSPs powerful: you reduce your taxes and grow your retirement savings simultaneously.
2026 RRSP Contribution Limit
Your RRSP room is calculated as 18% of your previous year's earned income, up to a maximum of $33,810 for 2026. The "earned income" includes employment income, self-employment income, and rental income, but not investment income or pension income. Unused room carries forward indefinitely, so you can catch up in future years.
Tax-Deferred Growth
Money inside your RRSP grows tax-free. Whether you invest in stocks that appreciate, bonds that pay interest, or GICs that compound, you pay no tax on the growth until you withdraw. This allows decades of compound growth without annual tax dragβa major advantage over non-registered accounts.
RRIF Conversion at Age 71
By 31 December of the year you turn 71, you must convert your RRSP to a Registered Retirement Income Fund (RRIF) or purchase an annuity. A RRIF requires you to withdraw a minimum percentage each year (starting at 5.40% of the portfolio, increasing as you age). These withdrawals are taxed as income.
Canadian Example (2026)
RRSP limit: 18% of $95,000 = $17,100 (below the $33,810 ceiling)
Contributing: $12,000
Marginal tax rate (Ontario): ~43.4%
Tax refund estimate: ~$5,208 (43.4% of $12,000)
At 6%/year return over 25 years: $12,000 grows to ~$51,500
After-tax value at retirement (assuming 26% withdrawal tax rate): ~$38,000
Net gain: ~$26,000 after accounting for taxes and your original contribution
The RRSP Advantage: "Tax Refund Trick"
Many Canadian financial advisors suggest the "tax refund reinvestment trick": after contributing to an RRSP and receiving your tax refund from the CRA, reinvest that refund back into your RRSP. Here's how it works:
- Contribute $10,000 to your RRSP (reduces your taxable income)
- File your tax return and receive a $4,340 refund (at 43.4% marginal rate)
- Immediately contribute that $4,340 back to your RRSP
- Your total RRSP contribution is now $14,340 with the same effective cost
This dramatically accelerates your RRSP growth without requiring additional money out of pocket.

Tips to Maximise Your RRSP
Contributions made on 1 January have 12 months to compound versus contributions made in May. Even a few months of extra growth adds up over decades. Set up automatic monthly contributions for discipline.
Use the "tax refund trick": when you get your refund from the CRA, immediately contribute it back to your RRSP. This amplifies your contributions without additional out-of-pocket cost.
If you earn significantly more than your spouse, contribute to a spousal RRSP. You get the full tax deduction, but your spouse owns the account and will pay tax on withdrawals at their (likely lower) rate in retirement. This reduces your combined tax liability.
If your marginal tax rate is above 40%, prioritise RRSP contributions first. The immediate tax refund is substantial. Use TFSA for additional savings after maxing your RRSP room.
