Estimate your credit-card interest cost in Canada
Enter a balance, annual percentage rate, and monthly payment to estimate your payoff time, total interest, and total payments. Your inputs stay in your browser.
Calculate your estimate
This educational estimate is not financial advice, a credit offer, or a guarantee. It excludes fees, new purchases, rate changes, grace periods, and issuer-specific daily compounding or payment-allocation rules.
Use the result as a planning signal
A longer payoff estimate can help you test a larger recurring payment, reduce new card spending, or compare the cost of lower-rate options. Before changing products, account for transfer fees, promotional-rate expiry dates, eligibility requirements, and the risk of adding new debt.

Frequently asked questions
How is the interest estimate calculated?
The tool uses an approximate monthly rate equal to APR divided by 12, adds that interest to the balance, then subtracts the selected payment.
Does Bremo store my inputs?
No. The calculation runs locally in your browser and the form does not submit your balance, rate, or payment.
Will this match my statement exactly?
Not necessarily. Many issuers calculate interest daily, and fees, new purchases, promotional rates, grace periods, and payment-allocation rules can change the actual result.
