How to Use This Canada RRSP Calculator
Enter your prior year earned income (2024 income) to calculate your 2025 contribution limit (18% up to C$32,490). Add any unused room from previous years (found on your CRA Notice of Assessment). Enter your planned contribution to see the estimated tax refund at your marginal rate.
The Formula
2025 Contribution Limit = Min(Prior Year Income Γ 18%, C$32,490)
Total Available Room = 2025 Limit + Unused Prior Year Room β Pension Adjustment
Tax Refund = Contribution Γ Combined Federal + Provincial Marginal Rate
Refund Check: Ensure contribution β€ Total Available Room
Total Available Room = 2025 Limit + Unused Prior Year Room β Pension Adjustment
Tax Refund = Contribution Γ Combined Federal + Provincial Marginal Rate
Refund Check: Ensure contribution β€ Total Available Room
Example
Chen, Ontario, $90,000 2024 income, $5,000 unused room, contributes $16,200 in 2025:
2025 limit: $90,000 Γ 18% = $16,200 (under $32,490 max)
Total available room: $16,200 + $5,000 = $21,200
Contribution: $16,200 (within room)
Combined marginal rate (~Ontario ~33.9%): $16,200 Γ 33.9% = ~$5,492
Estimated tax refund: ~C$5,492
2025 limit: $90,000 Γ 18% = $16,200 (under $32,490 max)
Total available room: $16,200 + $5,000 = $21,200
Contribution: $16,200 (within room)
Combined marginal rate (~Ontario ~33.9%): $16,200 Γ 33.9% = ~$5,492
Estimated tax refund: ~C$5,492

Frequently Asked Questions
How does an RRSP reduce your taxes?
RRSP contributions are deducted from your taxable income. If you contribute $10,000 to your RRSP and your marginal tax rate is 33%, you receive a $3,300 tax refund when you file your return. The money then grows tax-sheltered inside the RRSP until withdrawal. At retirement, withdrawals are added to your income and taxed, but often at a lower rate than your working-years rate.
What is the RRSP contribution limit for 2025?
For 2025, the RRSP contribution limit is 18% of your prior year earned income (2024 income), up to a maximum of C$32,490. You must also have available RRSP contribution room, which accumulates from unused room in previous years. Your current available room is shown on your CRA Notice of Assessment or through your CRA My Account.
What is the difference between RRSP and TFSA?
RRSP contributions are tax-deductible (reducing income now) but withdrawals are taxed. TFSA contributions are made with after-tax money (no deduction) but withdrawals are completely tax-free. RRSP is generally better if your tax rate will be lower at retirement than during your working years. TFSA is better if your rate at retirement will be the same or higher, or if you need flexibility to withdraw without tax consequences.
When should I take my RRSP refund?
You must convert your RRSP to a RRIF (Registered Retirement Income Fund) or annuity by December 31 of the year you turn 71. Many retirees convert earlier to start drawing income. You can also make RRSP withdrawals before 71 for large expenses, home purchases (Home Buyers Plan: up to $35,000), or education (Lifelong Learning Plan: up to $10,000/year). Withdrawals before retirement are taxed at your current marginal rate.
What is the spousal RRSP strategy?
You can contribute to your spouse's or common-law partner's RRSP and claim the deduction on your own return. This is useful for income splitting in retirement: if one partner earns significantly more, contributing to the lower-earner's spousal RRSP shifts future retirement income to them. At retirement, withdrawals from the spousal RRSP are taxed in the lower-income spouse's hands (provided the contribution was made 3+ years ago).
