How Credit Card Interest Works

Credit card interest is calculated using your Annual Percentage Rate (APR), divided by 12 to get a monthly rate, applied to your outstanding balance. When you make only the minimum payment, most of that payment goes toward interest rather than reducing your actual debt. This is why credit card balances can feel like they never go down.

For example, on a $5,000 balance at 22.99% APR, your monthly interest charge is about $96. If your minimum payment is $100, only $4 goes toward the actual balance. At that rate, it would take over 30 years to pay off the card and you’d pay over $11,000 in interest alone.

Strategies to Pay Off Credit Cards Faster

Even small increases in your monthly payment can dramatically reduce your payoff time. Use the comparison table in the calculator above to see how paying just 25% or 50% more each month changes your timeline. Beyond increasing payments, consider balance transfer cards with 0% introductory APR periods, which can save significant interest. You can also use the debt snowball or avalanche methods if you have multiple cards — our Debt Snowball Planner and Debt Avalanche Planner can help with that.

Why Minimum Payments Keep You in Debt

Most issuers set the minimum payment at roughly 1% to 2% of the balance plus that month’s interest and fees, or a flat floor such as $25, whichever is greater. Because the interest portion is covered first, only a thin slice of a minimum payment reduces what you actually owe. On a $5,000 balance at 22% APR, a minimum payment of about $100 sends roughly $92 to interest in the first month.

That structure is why a balance can take decades to clear at the minimum while the total repaid ends up several times the original amount. The minimum also shrinks as the balance falls, which stretches the timeline further. Paying a fixed amount every month instead of the shrinking minimum is the single change that most shortens the payoff period.

Avalanche Versus Snowball

The avalanche method targets the highest interest rate first while paying minimums on everything else. It is mathematically optimal, producing the lowest total interest and the shortest payoff time. The snowball method targets the smallest balance first, which costs slightly more in interest but delivers a cleared account sooner and tends to be easier to sustain.

The gap between the two is usually smaller than people expect, often a few hundred dollars across several years, so the method you will actually stick to generally beats the one that looks better on paper. If your rates vary widely, avalanche is worth the discipline; if your balances are similar, snowball costs almost nothing. Our debt avalanche planner sequences multiple debts for you.

What Extra Payments Actually Change

Extra payments work disproportionately well early on, because interest is charged on the balance and every dollar removed stops accruing immediately. Adding $100 a month to a $5,000 balance at 22% APR typically cuts the payoff time by years rather than months and saves a large multiple of the extra amount contributed.

Timing matters too. Because credit card interest compounds daily on your average balance, paying earlier in the billing cycle reduces the average balance the interest is calculated against. Making two payments a month rather than one has a modest but real effect for this reason. You can see the daily cost of your balance with our APR to daily rate converter.

Payoff Time and Interest by Monthly Payment

The table below takes a single $5,000 balance at 22.99% APR and varies only the monthly payment. The point it makes is how non-linear the relationship is: the first increases buy you enormous savings, and later increases buy progressively less.

Monthly payment	Time to clear	Total paid	Total interest
$100	13 years 11 months	$16,700	$11,700
$150	4 years 6 months	$8,050	$3,050
$200	2 years 11 months	$6,870	$1,870
$250	2 years 2 months	$6,365	$1,365
$300	1 year 9 months	$6,080	$1,080
$400	1 year 3 months	$5,770	$770
$500	1 year	$5,600	$600

Look at the first two rows. Adding $50 a month, which is under $2 a day, cuts more than nine years off the timeline and saves around $8,650 in interest. Going from $400 to $500 saves only $170. If you can find extra money anywhere, the earliest increases are worth vastly more than the later ones, which is the opposite of how most people prioritise.

The reason the $100 row is so brutal is that the interest charge in month one is roughly $96, so barely $4 reduces the balance. Anything close to the minimum payment leaves you paying almost pure interest for years. You can see the daily version of this with our APR to daily rate converter.

Avalanche Versus Snowball: A Worked Ordering

The two methods only differ in which debt you attack first while paying minimums on the rest. With these three balances the orderings are completely reversed, which makes the trade-off easy to see.

Debt	Balance	APR	Avalanche order	Snowball order
Store card	$600	21.99%	3rd	1st
Card A	$2,400	27.99%	1st	2nd
Card B	$7,000	24.99%	2nd	3rd

Avalanche is mathematically optimal and will always cost less in total interest, but on a spread like this the gap is usually a few hundred dollars over several years, not thousands. Snowball clears the store card in a month or two, which some people need in order to keep going. The method you will actually finish beats the one that looks better on a spreadsheet, so choose honestly. Our debt avalanche planner sequences the full schedule either way.

How This Calculator Works

The tool amortises your balance month by month. Each month it applies the monthly periodic rate, which is your APR divided by twelve, to the outstanding balance, adds that interest, then subtracts your payment and carries the remainder forward. It repeats until the balance reaches zero, which is how it produces both the timeline and the total interest.

It assumes a fixed payment rather than the shrinking minimum most issuers calculate, because a fixed payment is what actually clears debt and what the comparison is designed to demonstrate. It also assumes no new purchases on the card and no change in APR. Real statements will differ slightly because issuers apply interest to your average daily balance rather than a single month-end figure, and because promotional or penalty rates can change mid-schedule.

Common Payoff Mistakes

Paying the minimum and believing you are making progress is the big one, and the first row of the table above shows why. A close second is continuing to spend on the card you are paying down, which resets your progress invisibly, since new purchases usually lose the grace period once you are carrying a balance.

Two more are worth avoiding. Ignoring a 0% balance transfer because of the fee often costs more than the fee itself would, so run the comparison before dismissing it with our balance transfer calculator. And draining an emergency fund to clear a card frequently backfires, because the next unexpected expense goes straight back onto the card at the same APR, leaving you with the debt and no cushion.

Frequently Asked Questions

What’s the minimum I should pay?

Always pay more than the minimum if you can. Minimum payments are typically 1-3% of your balance or $25, whichever is greater. They’re designed to keep you in debt longer, maximizing the interest the card issuer collects.

Should I pay off my highest-rate card first?

Mathematically, yes — this is the “avalanche method” and it saves you the most in interest. However, if you need motivational wins, the “snowball method” (paying off the smallest balance first) can keep you on track. Both are valid strategies.
