Finance Calculators
Estimate a Canadian debt payoff timeline, total interest, and debt-free date from balance, rate, payment amount, and extra payments.
Before you calculate
The debt avalanche method pays minimums on every debt, then sends extra money to the highest-rate balance first.
The debt snowball method starts with the smallest balance first, which can help motivation even when it costs more interest.
Use this calculator to test payment size, payoff month, total interest, and whether a proposed payment is too low to reduce the balance.
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.
High-interest debt can grow quickly because interest is charged repeatedly on remaining balances.
Avalanche pays highest-rate debts first. Snowball pays smallest balances first for motivation.
Interest adds to the balance when payments do not fully cover charges and principal reduction.
Frequently asked questions
The monthly payment may not cover the interest being added.
No. Add fees to the debt amount if you want them included.
Enter each balance separately if the rates differ. The highest-rate debt usually deserves the extra payment first.
Still test it. Small extra payments can shorten payoff time, especially when they go to the highest-rate balance.
Disclaimer
Debt payoff timing depends on interest rates, fees, payment dates, balance changes, and whether you keep using the account. Use this estimate to choose a repayment order, then confirm amounts with your lender statements.
