The difference between paying a fixed monthly amount and paying only the minimum on a credit card balance is often measured in years and thousands of dollars of interest. This calculator projects two payoff paths side by side: a fixed payment you choose, and the declining minimum payment schedule used by most Canadian credit card issuers. The chart shows the balance over time for both approaches, and the crossover makes the cost of minimum-only payments visible at a glance.
How long does it take to pay off $5,000 on a credit card at 19.99%?
At a 19.99% annual rate with a fixed monthly payment of $200, a $5,000 balance is paid off in approximately 31 months with total interest of approximately $1,169. Paying only the minimum (starting at roughly 2% of the balance, with a $10 floor) extends the payoff to well over 20 years and total interest can exceed $5,000, more than the original balance. A fixed payment that is two to three times the starting minimum eliminates the debt in a fraction of the time.
How credit card interest is calculated
Daily periodic rate
Canadian credit cards state an annual interest rate (APR) and apply it daily to the outstanding balance. The daily periodic rate is the annual rate divided by 365. A 19.99% card has a daily rate of approximately 0.05476%. Over a 30-day billing cycle, the effective monthly rate is approximately 1.643%. Interest is calculated on the average daily balance during the cycle. Carrying a balance from month to month means interest is charged on interest already accrued, compounding the cost over time.
How the minimum payment works
Canadian credit card issuers are required by federal regulation to set a minimum payment that covers at least interest plus fees plus 1% of the principal balance, or a flat dollar minimum (typically $10 to $25), whichever is greater. In practice, many issuers set minimums at 2% to 3% of the outstanding balance or a fixed minimum floor. As the balance declines, the minimum payment also declines, which means progressively less principal is repaid each month. The result is a long tail: a large portion of minimum payments early in the repayment period goes to interest, with principal reduction accelerating only once the balance is substantially reduced.
The fixed payment advantage
Choosing a fixed monthly payment above the minimum stops the minimum from declining. More of each payment goes to principal as the balance falls, because interest charges (calculated on the balance) shrink while the payment stays constant. The payoff point arrives sooner and total interest paid is far lower. The chart in this calculator makes this difference visual: the navy line (fixed payment) drops to zero significantly earlier than the red dashed line (minimum payment).

Payoff time and total interest at different payment amounts ($5,000 at 19.99%)
| Monthly payment | Payoff time | Total interest paid |
|---|---|---|
| Minimum only (2% declining) | 30+ years | $5,000+ |
| $150 | ~47 months | ~$2,040 |
| $200 | ~31 months | ~$1,169 |
| $300 | ~19 months | ~$675 |
| $500 | ~11 months | ~$367 |
Worked example: $8,000 balance, 22.99% APR, $300 fixed payment
A cardholder carries an $8,000 balance on a card charging 22.99% annually. The monthly rate is approximately 1.910%. Month 1: interest charge is $8,000 × 1.910% = $152.80. Principal repaid: $300 minus $152.80 = $147.20. Balance after payment: $7,852.80. Month 2: interest on $7,852.80 is $150.01. The fixed $300 continues to pay down the balance until month 37, when the balance reaches approximately $255 and the final smaller payment completes payoff. Total interest paid: approximately $2,925. Total payments: approximately $10,925 on an $8,000 debt.
On the same debt with minimum payments only (starting at $240, declining to a $10 floor), payoff extends to over 30 years and total interest exceeds $8,000.
Rules and edge cases
Grace period: the key to avoiding interest entirely
Most Canadian credit cards offer a minimum 21-day grace period on new purchases. If the full statement balance is paid by the due date each month, no interest is charged. Interest accrues only when a balance is carried from one statement cycle to the next. The grace period applies to purchases; cash advances and balance transfers typically begin accruing interest immediately, with no grace period and often at a higher rate (24.99% is common for cash advances).
Balance transfer promotions
Some issuers offer promotional balance transfer rates as low as 0% for a fixed period (typically 6 to 12 months). A cardholder who transfers a $5,000 balance at 0% for 12 months and makes a fixed payment of $417 per month eliminates the balance with zero interest. The risk is that any remaining balance after the promotional period reverts to the standard rate (often 19.99% or higher) immediately. Promotional transfers typically come with a one-time fee of 1% to 3% of the transferred amount.
Low-rate credit cards
Some Canadian financial institutions offer credit cards with rates as low as 12.99% or even 9.99%, in exchange for an annual fee of $35 to $120. For a cardholder who regularly carries a balance, the math often favours paying the annual fee to access the lower rate. At $5,000 outstanding, the difference between 19.99% and 12.99% is approximately $350 in annual interest, which exceeds the fee on most low-rate cards.
Debt avalanche vs debt snowball
When multiple credit cards carry balances, two payoff strategies are commonly compared. The debt avalanche directs extra payments to the highest-rate balance first, minimizing total interest paid. The debt snowball directs extra payments to the smallest balance first regardless of rate, building momentum through quicker wins. Mathematically, the avalanche saves more money. Behaviourally, the snowball works better for some people because early payoffs provide motivation. This calculator models one card at a time; the debt consolidation calculator handles multi-debt comparison.
Credit score impact of carrying a balance
Credit utilization, the ratio of current balances to total credit limits, is a significant factor in Canadian credit scores. Carrying a balance above roughly 30% of the total credit limit can reduce credit scores. A $5,000 balance on a $6,000 limit card represents 83% utilization, which is high. Paying down the balance improves utilization and typically improves credit scores within one to two reporting cycles.
Frequently asked questions
- How does credit card interest compound in Canada?
- Credit card interest in Canada is typically calculated on the average daily balance during the billing cycle, using the daily periodic rate (annual rate divided by 365). If the full balance is not paid by the due date, interest accrues on the unpaid amount, and that interest is added to the principal on the next statement, compounding the cost each cycle.
- What is the minimum payment on a Canadian credit card?
- Federal regulations require credit card issuers to set a minimum payment of at least interest and fees plus 1% of the principal balance, or a fixed floor amount, whichever is greater. In practice, most issuers set minimums at 2% to 3% of the outstanding balance with a floor of $10 to $25. The exact formula is disclosed in the cardholder agreement.
- How long does it take to pay off $5,000 at 19.99%?
- With a fixed $200 monthly payment at 19.99% annual interest, a $5,000 balance is paid off in approximately 31 months with total interest of approximately $1,169. With minimum payments only (starting at roughly 2% of the balance), payoff can take 30 or more years, with total interest exceeding the original balance.
- What is the grace period on a Canadian credit card?
- Most Canadian credit cards provide a minimum 21-day grace period on new purchases. Paying the full statement balance by the due date within the grace period means no interest is charged. Carrying any balance from the previous statement eliminates the grace period for new purchases. Cash advances and balance transfers typically have no grace period and begin accruing interest immediately.
- Is it better to pay more than the minimum on a credit card?
- Yes. Even a small increase above the minimum dramatically reduces total interest and payoff time. On a $5,000 balance at 19.99%, the difference between paying the minimum and paying $200 per month is roughly 28 extra years and over $4,000 in additional interest. The most effective strategy is a fixed payment above the minimum that does not decrease as the balance falls.
- What is a balance transfer and how does it help?
- A balance transfer moves a credit card balance from a high-rate card to a card with a lower promotional rate, often 0% for 6 to 12 months. The savings can be substantial: zero interest for 12 months on a $5,000 balance at 19.99% saves approximately $1,000. Most balance transfers charge a fee of 1% to 3% of the transferred amount. Any balance remaining after the promotional period reverts to the standard rate.
- How does carrying a credit card balance affect a credit score?
- Credit utilization, the percentage of available credit currently in use, is a major component of Canadian credit scores. A balance above roughly 30% of the credit limit is considered high utilization and typically lowers credit scores. Paying down the balance reduces utilization and can improve scores within one or two reporting cycles after the lower balance is reported to the credit bureau.
- What is a low-rate credit card in Canada?
- Low-rate cards charge interest at 9.99% to 12.99% instead of the standard 19.99% to 22.99%, usually in exchange for an annual fee of $35 to $120. For a cardholder who regularly carries a balance, the fee is often worth it. On a $5,000 ongoing balance, the difference between 19.99% and 12.99% is roughly $350 in annual interest savings, more than the fee on most low-rate cards.
- What is the debt avalanche method?
- The debt avalanche directs all available extra payment money to the debt with the highest interest rate first, while making minimum payments on all others. Once the highest-rate debt is paid off, the freed-up payment is added to the next highest-rate debt. This method minimizes total interest paid and is the mathematically optimal payoff strategy when multiple debts are outstanding.
- Does paying the minimum hurt your credit score?
- Paying only the minimum does not directly damage your credit score, because you are meeting the minimum payment obligation. However, maintaining a high balance relative to the credit limit (high utilization) can reduce your credit score. The long-term cost is more financial than credit-scoring: minimum payments maximize total interest paid and extend the time you carry debt.
