Credit Card Payoff Calculator (Canada)

A credit card balance moves slowly because interest is added to what you owe before your payment is applied, so part of every payment is used up before it reduces the debt. At 19.99%, a $5,000 balance is charged about $83 in the first month. This calculator runs the arithmetic month by month at the fixed payment you choose and reports when the card clears, the interest it cost, and whether the payment is large enough to make progress.

Simulating the balance one month at a time

Each cycle has three steps in the same order: add the month’s interest, subtract the payment, carry the remainder forward. The loop runs until the balance reaches zero, counting months and interest.

That order explains the shape of a payoff. Early on, much of your payment covers interest and only the rest reduces the debt. As the balance falls, so does the interest charge, and more of the same payment goes to principal. Progress speeds up, which is why the last six months of a payoff feel nothing like the first six.

What the APR means each month

At 19.99% the monthly rate is about 1.67%, so $5,000 attracts roughly $83 and a $200 payment leaves about $117 reducing the debt.

Enter the rate that applies to your balance, not the headline number on the card. Purchases, cash advances and promotional balances can each carry a different rate on the same account. Credit unions are mostly provincially regulated, so the terms, disclosure rules and consumer protections on a credit union card can differ from a bank card. The rate on your own statement is the one that matters.

The 21-day grace period, and how you lose it

A federally regulated institution must give you at least 21 days after the end of the billing cycle before payment is due, and it cannot charge interest on that cycle’s purchases if you pay the full balance by the due date. While you use that grace period, a credit card costs nothing in interest.

It is all or nothing. Pay $4,900 of a $5,000 statement and interest is charged on the cycle’s purchases anyway. Once you carry a balance you stay outside the grace period until you clear a full statement again, which is why moving from paying in full to carrying a balance costs far more than the unpaid amount suggests.

Cash advances charge from day one

A cash advance has no grace period. Interest starts the day you withdraw the money and runs until it is repaid, and most cards charge a higher rate on advances plus a transaction fee. Balance transfers outside a promotion and some cash-like transactions are usually treated the same way.

If part of what you owe is an advance, run it through the calculator as a separate balance at its own rate. Blending it into the purchase balance understates the cost.

Minimum payments and the Quebec exception

A typical Canadian minimum is a small percentage of the balance, sometimes with a dollar floor. Because it is a percentage of a shrinking balance, the required payment shrinks too, and the payoff stretches over years while interest keeps accruing.

Quebec is the only province that sets a minimum payment percentage in law, through its Consumer Protection Act, and has raised it over several years to stop residents from carrying card debt indefinitely. Elsewhere the issuer sets the minimum within federal disclosure rules.

A fixed payment, which this tool models, avoids the problem. It does not fall as the balance falls, so the share going to principal rises every month.

$5,000 at 19.99%, at two payment levels

Pay $200 a month. Month one adds about $83 of interest and leaves roughly $4,883. The balance clears in 33 months and costs about $1,521 in interest.

Pay $350 instead. The card clears in 17 months, about half the time, and the interest falls to about $758, half the cost. The extra $150 a month bought more than a proportionate improvement, because the debt spent much less time accruing interest.

Paying off more than one card

With several balances, order matters. Paying the highest rate first minimizes total interest; paying the smallest balance first clears an account sooner and keeps many people motivated. Both beat spreading a fixed budget evenly across every card.

A payday loan, if you have one, costs far more than any card once its fee is expressed as an annual rate, so it goes first whatever its size. A personal line of credit is priced off your lender’s prime rate, which follows the Bank of Canada’s policy rate, while card rates generally do not move when the policy rate does, so a line of credit is the balance whose rate can change during your plan.

What the model does not capture

This is a planning estimate, not a statement from your issuer. It assumes one fixed monthly payment, a constant APR and interest charged once a month on the balance. Many Canadian cards accrue interest daily, which makes the real cost slightly higher. It leaves out annual fees, over-limit and foreign transaction fees, promotional rates that expire, new spending on the card, and the shrinking minimum. Take the exact rate and balance from your statement before acting on the result.
