How to Use
Enter the balance and the card rate
Take the APR from your statement, not from the advert. The answer appears immediately as a number of months.
Pick how you want to pay
Either fix a monthly amount and see how long it takes, or fix a deadline and see the payment it requires. Both directions work.
Nudge the payment up and watch the interest fall
Adding a small amount to the monthly payment usually cuts both the term and the total interest sharply — this is the fastest lesson the tool teaches.
Beware the minimum payment
If the tool says “Never”, your payment barely covers the interest and the balance will not fall. Raise it until a real term appears.
A useful comparison to run: your current payment versus that payment plus 10%. On a typical card rate the second option usually saves months and a noticeable amount of interest.
Optimization Guide & Technical Info
Tired of Paying Only the Minimum?
Minimum payments are designed to keep you in debt for as long as possible. High credit card APRs ensure that most of your payment goes toward interest rather than the principal balance. Our calculator shows you exactly how much money you can save by increasing your monthly payment by even a small amount.
Interest is charged on what you still owe, so every extra payment stops interest on that amount from the next month on. Paying down a card therefore earns exactly its rate, with no risk: at 20% a year, each dollar paid early saves 20 cents of interest a year.
Key Features
- Calculate payoff time with minimum or custom payment amounts
- Show total interest paid over the payoff period
- Three ways to set the payment: a fixed amount, a payoff goal in months, or the minimum only
- Calculate the payment needed to pay off by a target date
- Tells you plainly when the payment does not even cover the interest
- Visual timeline showing balance reduction
For Specific Situations
One card
take the APR from the statement and fix a monthly amount you will actually keep paying.
Several cards
run each one separately and clear the highest rate first — that ordering saves the most interest.
Balance transfer
compare the current card against the promotional rate plus the transfer fee, not against the rate alone.
Minimum payment trap
if the tool answers “Never”, the payment only covers interest — raise it until a term appears.
How does the repayment calculation work?
The calculator simulates the repayment month by month: interest is charged on the balance at your card’s rate, it is taken out of your payment first, and the rest reduces the debt.
With only the minimum, the payment shrinks together with the debt, so most of it keeps going to interest. Switch the strategy to the minimum payment, enter your card’s percentage and see how many years that takes — then compare it with a fixed payment.
The calculator clearly shows: increasing the monthly payment even by a small amount can reduce the repayment period several times and save a significant amount on interest.

Tips and best practices
- Never pay only the minimum — it maximizes the bank's profit and minimizes your progress
- Pay the highest-interest card first (avalanche method) to minimize total interest
- Or pay the smallest balance first (snowball method) for quick motivational wins
- Stop using the card while paying it off — new charges undermine your payoff progress
- Consider a 0% balance transfer if available — but commit to paying it off before the promotional period ends
- Set up automatic payments above the minimum to ensure consistent progress without relying on willpower
Formulas and Algorithms
n = −log(1 − P·i/M) / log(1 + i) Months to clear the balance at a fixed monthly payment M.
i = APR / 12 / 100 Card rates are quoted per year and charged per month.
M ≤ P · i ⇒ n → ∞ If the payment does not exceed one month of interest, the balance never falls.
Σ = M · n − P The price of the delay: everything paid above the balance itself.

Frequently Asked Questions
Q: Why is minimum payment a bad strategy?
A: Because the minimum shrinks with the debt, so less and less of each payment goes to the balance. Counted in this calculator: $5,000 on a card at 20% a year, paying only a 3% minimum, takes 183 months — over 15 years — and the interest, $5,602, is larger than the debt itself. Paying the same first $150 every month instead clears it in 50 months with $2,359 of interest.
Q: What is the avalanche method and the snowball method?
A: Avalanche method: Pay off the debt with the highest rate first - this saves more money. Snowball method: start with the smallest debt - this gives quick motivation. Mathematically, an avalanche is more efficient.
Q: How to lower your interest rate?
A: Ask your bank for a lower rate (if you have good credit), transfer your balance to a card with a promotional rate, or consider refinancing through a personal loan with a lower rate.
