About This Tool
Why use Credit Card Interest Calculator?
Standard Canadian credit cards often charge interest around 20% on purchases and more on cash advances. Federal rules give you an interest-free grace period of at least 21 days on new purchases when you pay your full balance by the due date.
Once you carry a balance, interest builds quickly and the minimum payment mostly covers interest. Your statement shows how long it would take to repay the balance with minimum payments only. Setting a fixed monthly payment is one of the simplest ways to become debt-free faster.

Credit Card Interest Calculator FAQs
What is the credit card grace period in Canada?
Federally regulated issuers must give at least a 21-day interest-free grace period on new purchases if you pay the full balance by the due date. Cash advances usually accrue interest immediately.
Why does my balance go down so slowly?
At around 20% interest, a large part of a small payment goes to interest. Paying more than the minimum reduces the principal faster and cuts total interest.
Should I consolidate credit card debt?
A lower-rate personal loan, line of credit or balance transfer can reduce interest, but only if you avoid building new card balances. Compare the total cost, including fees.
Which currency does this credit card interest use?
Amounts are shown in Canadian Dollars (CAD). The formulas are the same everywhere, so you can switch to another country version if you need a different currency.
