RRSP tax savings calculator
RRSP contributions are deducted from your income before tax. Enter your income, province and contribution to see how much tax you save and what the contribution really costs you.
How an RRSP saves you tax
Money you put into a Registered Retirement Savings Plan (RRSP) is deducted from your taxable income, so you save tax at your highest rate. The tax is deferred, not cancelled: you pay income tax when you take the money out, usually in retirement when your income and tax rate are lower.
For example, someone earning $80,000 in Ontario who contributes $5,000 saves $1,482.50 in income tax, so the contribution really costs them $3,517.50. The same contribution on $50,000 of income saves $1,102.50, because the tax rate on that slice of income is lower.

Frequently asked questions
Should I choose an RRSP or a TFSA?
An RRSP is usually better if your tax rate now is higher than it will be when you withdraw the money. A TFSA is often better if your income is low now, because withdrawals are tax-free and do not affect income-tested benefits. Many people use both. See our TFSA contribution room calculator.
When do I get the tax back?
You claim the deduction on your tax return and usually receive it as part of your refund. You can also ask your employer to reduce the tax taken from your pay by filing form T1213 with the CRA.
Does an RRSP reduce CPP or EI?
No. CPP and EI are based on your pay, not your taxable income, so they stay the same. This calculator shows the saving in income tax only.
