RRSP Calculator

A Registered Retirement Savings Plan (RRSP) is the cornerstone of retirement saving for many Canadians. It offers two distinct tax advantages that work together: contributions are tax-deductible, reducing the income tax you pay now, and the investments inside grow tax-deferred, so you pay no tax on gains, interest or dividends until you withdraw the money in retirement.

The upfront deduction is the headline benefit. When you contribute, you can deduct the amount from your taxable income, which generates a tax refund equal to your contribution multiplied by your marginal tax rate. For someone in a 35% marginal bracket, a $10,000 contribution can produce roughly $3,500 back. A common strategy is to reinvest that refund — into the RRSP or a TFSA — to amplify the benefit. Because the refund depends on your marginal rate, RRSPs are especially powerful for higher earners.

Your ability to contribute is governed by RRSP contribution room, which builds at 18% of your previous year's earned income up to an annual maximum (around $32,490 for 2025), plus any unused room carried forward from past years. Contributing more than your room can trigger penalties, so it's worth checking your limit on your CRA notice of assessment.

The tax deferral is the other engine of growth. Inside the RRSP, your investments compound without the drag of annual taxes, which over decades can produce a significantly larger balance than a taxable account. The trade-off is that withdrawals in retirement are taxed as ordinary income. The strategy works best when your tax rate in retirement is lower than when you contributed — you get the deduction at a high rate now and pay tax at a lower rate later.

RRSPs have rules to understand. They must be converted to a Registered Retirement Income Fund (RRIF) or annuity by the end of the year you turn 71, after which minimum withdrawals apply. Special programs like the Home Buyers' Plan and Lifelong Learning Plan let you borrow from your RRSP tax-free for a first home or education, with repayment rules. The TFSA is a common complement: it offers tax-free (rather than tax-deferred) growth and is often favoured when your current tax rate is low.

This calculator estimates your immediate tax refund and projects your RRSP's tax-deferred growth, helping you see both the near-term and long-term value. Your actual refund and outcome depend on your full tax situation and investment returns, so treat the figures as a guide.
