Debt Payoff Calculator Canada

Debt freedom is a date, not a feeling, and this calculator finds yours. Enter a balance, its interest rate and the fixed monthly payment you can hold, and it shows the month you finish, the total interest the debt will cost, and what raising the payment does to both.

Debt balance ($)Interest rate (APR, %)Fixed monthly payment ($)

Assumes the same payment every month, no new borrowing on the debt, and interest compounded monthly. Credit cards in Canada compound on their own terms; the pattern of the result, not the last cent, is what to plan around.

How it works

A fixed payment attacks debt faster every month, because the interest portion shrinks as the balance falls, so more of the same payment lands on principal. That snowball inside a single debt is why the second half of a payoff is quicker than the first.

With several debts, order matters. The avalanche method pays minimums on everything and throws the extra at the highest rate first, which is the cheapest in total interest. The snowball method clears the smallest balance first for motivation. Both beat spreading extra money evenly, and this calculator costs any single debt either way.

Worked example

The calculator’s own output for a $15,000 debt at 12% paid at $400 a month:

Item	Amount
Balance / rate / payment	$15,000.00 at 12% with $400.00 a month
Time to debt-free	48 months (4 years, 0 months)
Total interest	$3,894.35
Total paid overall	$18,894.35

Frequently asked questions

How much faster does an extra $100 a month pay off debt?

On the example debt, raising $400 to $500 a month shortens the payoff from 48 to about 37 months and saves roughly $900 of interest. Small payment increases have outsized effects because every extra dollar goes straight to principal.

Avalanche or snowball: which is better?

Avalanche (highest rate first) always costs less interest. Snowball (smallest balance first) often keeps people going longer. The best method is the one you will still be using in month six.

Should I use a balance-transfer card to pay off debt?

A promotional 0% or low-rate transfer can cut interest sharply, but watch the transfer fee (often 1% to 3%), the regular rate when the promotion ends (often above 20%), and the rule that new purchases may not share the low rate.

Does paying off debt improve my credit score?

Usually yes over time: lower balances reduce your credit utilisation, and a record of on-time payments builds history. Keep old cards open after payoff if there is no annual fee, because closing them can raise your utilisation.

When is a consolidation loan worth it?

When its rate is clearly below your current debts’ weighted rate and the term is no longer than your current payoff timeline. A lower payment stretched over more years can cost more interest despite the lower rate.
