RRSP Tax Savings
How to Use This RRSP Tax Savings Calculator
This calculator estimates the exact tax refund generated by an RRSP contribution using current federal and provincial tax brackets, based on your income and contribution amount.
How It’s Calculated
Tax Savings = Contribution Amount × Marginal Tax Rate (federal + provincial combined)
The refund reflects your marginal rate, which is why a contribution is worth more in a high-income year.
Example
A $10,000 RRSP contribution for someone in Ontario with a 43% combined marginal rate generates roughly a $4,300 tax refund — effectively meaning the contribution only cost $5,700 out of pocket.
Frequently Asked Questions
Is the RRSP refund the same as the RRSP’s investment growth?
No — the refund is a tax-timing benefit from the contribution itself. Investment growth inside the RRSP is separate and continues tax-deferred until withdrawal.
Do I have to claim my full RRSP deduction the year I contribute?
No — contributions can be made in one year and the deduction carried forward and claimed in a future, higher-income year for a bigger tax benefit.
What happens when I withdraw from an RRSP?
Withdrawals are taxed as regular income in the year taken out, which is why RRSPs work best when withdrawals happen in retirement at a lower marginal rate than during your working years.
