The Mathematics of the Daily Periodic Rate
Unlike most installment loans, card issuers charge interest daily on your average daily balance:
DPR = APR ÷ 365
Daily Interest = Average Daily Balance × DPR—
Balance Transfer & 0% APR Benchmark
A 0% intro balance transfer trades interest for an upfront fee. Compare the two over an 18-month promo:
A transfer only pays off if you clear the balance before the promo ends; any remaining balance reverts to the card's regular APR.
Why credit card interest is so costly
Credit cards typically carry among the highest interest rates of any common consumer debt, often 18-29% APR, compared to single-digit rates for many mortgages or auto loans. Interest also usually compounds daily, meaning balances can grow faster than borrowers expect if only minimum payments are made.
Because of this, credit card debt is generally considered a top priority to pay off aggressively before focusing on lower-interest debt or even some investing goals, since few guaranteed investment returns can outpace typical credit card APRs.

A worked example
A $3,000 balance at 22% APR with $120/month payments takes 34 months to pay off, with about $1,050 in total interest.
Raise the payment to $200/month instead, and payoff time drops to 18 months with about $540 in interest — roughly half the time and half the interest cost from an $80/month increase.
Balance transfer as an alternative strategy
Some credit cards offer promotional 0% APR balance transfer periods, which can dramatically reduce the total interest paid if you can pay off the balance within the promotional window — though transfer fees (often 3-5% of the balance) and the rate that applies after the promo period both need to be factored in.
Whether a balance transfer makes sense depends on the transfer fee versus the interest you'd otherwise pay, and your realistic ability to pay down the balance before the promotional rate expires.

How long minimum payments take: $5,000 at 24.99% APR
Issuers set the minimum in different ways, so check your statement. These are the three formulas the calculator uses, with no new purchases.
| Minimum formula | First payment | Time to pay off | Total interest | Total paid |
|---|---|---|---|---|
| 1% of balance + interest (min $25) | $154.12 | 236 months (19 yr 8 mo) | $9,278 | $14,278 |
| 2.5% of balance (min $25) | $125.00 | 472 months (39 yr 4 mo) | $21,123 | $26,123 |
| 3% of balance (min $35) | $150.00 | 216 months (18 yr 0 mo) | $9,546 | $14,546 |
What a fixed payment changes
The same $5,000 at 24.99% APR paid with a fixed amount every month instead of a falling minimum.
| Monthly payment | Time to pay off | Total interest | Total paid |
|---|---|---|---|
| $150 | 58 months (4 yr 10 mo) | $3,622 | $8,622 |
| $200 | 36 months (3 yr 0 mo) | $2,135 | $7,135 |
| $250 | 27 months (2 yr 3 mo) | $1,535 | $6,535 |
| $350 | 18 months (1 yr 6 mo) | $997 | $5,997 |
| $500 | 12 months (1 yr 0 mo) | $666 | $5,666 |
Monthly interest by balance and APR
Balance × APR ÷ 12 is a close estimate of one month's interest. Issuers actually compute it daily, so a 30-day cycle on $5,000 at 24.99% is about $102.70, using a daily rate of 0.0685%.
| Balance | 15% APR | 19.99% APR | 24.99% APR | 29.99% APR |
|---|---|---|---|---|
| $1,000 | $12.50 | $16.66 | $20.82 | $24.99 |
| $2,500 | $31.25 | $41.65 | $52.06 | $62.48 |
| $5,000 | $62.50 | $83.29 | $104.12 | $124.96 |
| $10,000 | $125.00 | $166.58 | $208.25 | $249.92 |
Monthly payment needed to be debt-free by a date
Level payment for 24.99% APR with no new charges. It is what the target-timeline mode solves for.
| Balance | 12 months | 18 months | 24 months | 36 months | 60 months |
|---|---|---|---|---|---|
| $2,500 | $237.60 | $167.97 | $133.42 | $99.39 | $73.36 |
| $5,000 | $475.20 | $335.93 | $266.83 | $198.77 | $146.73 |
| $10,000 | $950.39 | $671.87 | $533.67 | $397.55 | $293.45 |
| $15,000 | $1,425.59 | $1,007.80 | $800.50 | $596.32 | $440.18 |
| $20,000 | $1,900.79 | $1,343.74 | $1,067.33 | $795.09 | $586.91 |
Balance transfer: fee vs interest saved
Moving $5,000 from a 24.99% card to a 0% card for 18 months costs a one-time fee, usually 3% to 5%. Paying the original card off over the same 18 months would cost $1,047 in interest.
| Fee | Fee cost | New balance | Monthly for 18 months | Fee paid | Interest saved |
|---|---|---|---|---|---|
| 3% | $150.00 | $5,150.00 | $286.11 | $150.00 | $896.82 |
| 5% | $250.00 | $5,250.00 | $291.67 | $250.00 | $796.82 |
This only works if the balance is cleared inside the promo. If you pay only $200 a month on the $5,150 balance, $1,550 is left after 18 months and it then accrues at the card's regular rate.
Your statement already shows this
Under the federal CARD Act, card statements carry a minimum payment warning that says how long it would take to pay the balance with minimum payments only and what fixed payment clears it in 36 months. Compare it with the calculator's result for your card.

Frequently asked questions
Should I pay more than the minimum?
Generally yes — paying only the minimum on a high-APR card can take many years and cost substantially more in interest than the original balance.
What is a good strategy for paying off credit card debt fast?
Paying more than the minimum, avoiding new charges while paying down the balance, and considering a balance transfer to a lower-rate card (if available) are all common strategies to accelerate payoff.
Does carrying a balance help my credit score?
No — this is a common misconception. Paying your balance in full each month (or keeping utilization low) is better for your credit score than carrying a balance, which only costs you interest.
Is a balance transfer worth it?
It can be, if the transfer fee is smaller than the interest you'd save and you have a realistic plan to pay off the balance before the promotional rate ends — otherwise the remaining balance often reverts to a high standard rate.
How long does it take to pay off $5,000 on a credit card?
At 24.99% APR, a fixed $200 a month takes 36 months and costs about $2,135 in interest. Paying only a 1% plus interest minimum takes 236 months (19 yr 8 mo) and costs about $9,278.
How is credit card interest calculated?
Issuers divide the APR by 365 to get a daily rate and apply it to the daily balance. At 24.99% that is about 0.0685% a day, or roughly $102.70 over 30 days on $5,000.
How much do I need to pay each month to be debt-free in 24 months?
On $5,000 at 24.99% APR, about $266.83 a month, with total interest of about $1,404.
What is a minimum payment on a credit card?
The smallest amount you must pay by the due date to stay in good standing. It is often a percentage of the balance plus interest and fees, with a dollar floor. Check your statement for your card's formula.
Why do minimum payments take so long?
Most of an early minimum payment is interest. On $5,000 at 24.99%, the first minimum of about $154 includes about $104 of interest, so little of it reduces the balance.
Is a balance transfer worth it?
It can be when the fee (often 3% to 5%) is less than the interest you would otherwise pay and you can clear the balance in the promo period. On $5,000 over 18 months, a 3% fee is $150 against about $1,047 of interest.
What APR should I enter?
Use the purchase APR on your statement. Check whether it is variable, because it can change with the prime rate.
Do extra payments really save much?
Yes. Raising a fixed payment on $5,000 at 24.99% from $150 to $250 cuts the payoff from 58 months to 27 months.
