Finance Calculators
Estimate Canadian RRSP contribution room from prior-year earned income, unused room, pension adjustments, and contributions already made.
Account basics
An RRSP, or Registered Retirement Savings Plan, is a Canadian registered account mainly used for retirement savings. Eligible contributions can reduce taxable income for the year you claim them, which may create a refund or lower tax owing. Investments can grow tax-deferred inside the account, and withdrawals are generally taxable income later.
Read the RRSP guideBefore you calculate
An RRSP is mainly for retirement savings and tax deferral. Contributions can reduce taxable income when you claim them.
Room usually starts with unused RRSP room plus new room from prior-year earned income, then subtracts pension adjustments and contributions already made.
Use your CRA account or notice of assessment as the official number before contributing.
Main assumptions
Inputs are editable and should be updated with your real income, rates, province, fees, account limits, household details, and time horizon. Calculations are simplified so the result works best as a comparison tool: change one assumption at a time, note which inputs move the result most, and use the output to decide what records or source pages to check next.
Methodology
The calculator starts with the values you enter, applies the plain formula shown by the labels, and returns a directional planning result. When a default is provided, it is meant to be a reasonable starting assumption, not a live quote or a guaranteed rate. Change the inputs to match your province, provider, household, time horizon, and actual documents.
Example use
Use one conservative case, one expected case, and one stretch case. For a money calculator, that might mean a lower return, a current-rate case, and a higher-cost case. For a tax or account tool, compare your estimate with CRA, lender, employer, school, or provider records before you treat the result as actionable.
Source notes
Canooq reviews calculator pages periodically, but government limits, product terms, tax rules, interest rates, fees, eligibility conditions, and market prices can change. Use this section to identify the source behind the number: CRA or government pages for public rules, lender or provider pages for product terms, and your own statements for personal balances.
New RRSP room is generally 18% of previous-year earned income up to the annual dollar limit, plus unused room, then reduced by pension adjustments and contributions.
Workplace pensions and deferred profit sharing plans can reduce new RRSP room because they already provide registered retirement savings value.
Always confirm your official RRSP deduction limit in your CRA account or latest notice of assessment before contributing.
Frequently asked questions
No. This estimates room using common CRA rules. Your official deduction limit is the CRA number in your account or notice of assessment.
Enter your pension adjustment. It can reduce new RRSP room for the year.
Enter those contributions so the estimate subtracts them from your remaining room. Include contributions made in the first 60 days if you plan to claim them for the same tax year.
Use the CRA number as the official limit. This calculator helps you understand the formula, but CRA records, pension adjustments, and past contributions control the real room.
Disclaimer
RRSP room and refund estimates depend on earned income, unused room, pension adjustments, tax bracket, province, and contributions already made. Use your CRA account or notice of assessment as the official source before contributing.
