How accurate are these calculators?
They're good estimates, not exact figures. We use current CRA brackets, OSFI stress test rules, and provincial rates — but your real deductions depend on credits, deductions, and employer benefits your paystub will reflect. Use these to plan, then verify with CRA My Account or a payroll provider.
What is the OSFI mortgage stress test?
Lenders must qualify you at your contract rate + 2%, with a minimum floor of 5.25%. If your bank offers you 4.5%, they'll test your debt ratios at 6.5%. This typically reduces the maximum mortgage you qualify for by 15–20% compared to just using the posted rate.
What's the difference between TFSA and RRSP?
RRSP contributions reduce your taxable income now but withdrawals are taxed as income later. TFSA contributions are after-tax but all growth and withdrawals are tax-free. A rough rule: if you expect to be in a lower tax bracket in retirement, lean RRSP. If your income is under ~$50k today, TFSA usually wins.
How does CPP work?
You contribute 5.95% on earnings between $3,500 and the year's maximum ($68,500 in 2024). Your eventual monthly benefit depends on how much you contributed and for how long — the maximum in 2026 is about $1,364/month at age 65. Taking CPP early (age 60) reduces it by 7.2%/year; delaying to 70 increases it by 8.4%/year.
Do these calculators work for Quebec?
Yes, but with a note: Quebec uses the QPP instead of CPP, and has its own income tax system with different brackets. Our provincial salary calculator applies Quebec-specific rates, but for QPP contribution estimates specifically, the numbers use a simplified approach.
What is CMHC mortgage insurance?
If your down payment is less than 20% of the purchase price, you're required to buy CMHC (or equivalent) mortgage default insurance. It's 2.8–4.0% of your mortgage added to the loan. Our mortgage affordability calculator flags this threshold and adds the premium to your borrowing amount automatically.
