The short answer
For a hypothetical $5,000 balance at 18% APR, paying about $460 a month clears it in 12 months with roughly $499 in total interest. At 24% APR, about $475 a month clears it in 12 months with roughly $670 in interest. The exact payment needed depends on your actual balance and APR, so treat these as worked examples to model your own numbers against, not a rule to follow directly.
Working backward from a deadline
Most payoff questions start with a payment amount and ask how long it takes. This one starts with a deadline, 12 months, and asks what payment gets you there. The answer depends on your balance and APR, since a higher rate means more interest accrues each month, requiring a larger payment to still reach zero on the same schedule.
Finding the payment through simulation
The reliable way to find this number is to try a payment, simulate it month by month the same way you would check any payoff timeline, and adjust up or down until the balance reaches zero at month 12. A simple annual-rate shortcut can be close, but running the actual month-by-month numbers, with interest recalculated on the falling balance every month, confirms the payment will really finish on time.
Two APRs on the same $5,000 balance
At 18% APR, a payment of about $460 a month pays off a $5,000 balance in 12 months, with total interest across the year of roughly $499. At 24% APR, the same $5,000 balance needs about $475 a month to clear in 12 months, with total interest of roughly $670. The $15 difference in monthly payment reflects the higher rate adding more interest each month that the payment has to cover before it can reduce the balance.
A pattern worth expecting: a smaller final payment
Because interest shrinks as the balance shrinks, the last month in a 12-month schedule like this typically needs a smaller payment than the ones before it, since less interest has accrued on the small remaining balance. Do not be surprised if your final payment comes in below your regular monthly amount. That is the schedule working as expected, not an error.
Setting this up for your own balance
Use your real numbers rather than the ones above, since your balance and APR change the required payment.
- Write down your balance and current APR.
- Pick a trial monthly payment and simulate it month by month.
- If the balance is not at zero by month 12, raise the payment and try again.
- If it hits zero well before month 12, you can likely lower the payment slightly.
- Expect your last payment to be smaller than the rest and confirm the exact amount with your statement as you get close.
Worked example · illustrative numbers
Example: the 18% APR schedule month by month
This is a hypothetical $5,000 balance at 18% APR paid at $460 a month. Month one's interest is $5,000 times 0.18 divided by 12, which is $75.00, so the balance becomes $5,000 plus $75.00 minus $460, or $4,615.00. Interest keeps shrinking each month as the balance falls: by month 11 the balance is down to about $432.64, that month's interest is about $6.49, and the balance before the final payment is about $439.13. Since that is less than the regular $460 payment, the last payment only needs to be about $439.13 to bring the balance to zero at month 12.
Put this into practice with Debtless
Debtless lets you drag an extra-payment slider on the Plan tab and immediately see the projected debt-free date update, which is a faster way to find a payment that hits a target date than simulating by hand. It will not tell you what payment you can actually afford, since it does not know your budget.
Common questions
What if $460 or $475 a month is more than I can afford?
Then a 12-month payoff at that balance and rate may not be realistic right now. Simulate a smaller payment to see a longer, more comfortable timeline instead of forcing a deadline that strains your budget.
Does paying extra one month let me pay less the next?
An extra payment reduces the balance interest is calculated on going forward, which can shorten the timeline or lower future payments, but check with your lender on how they apply extra amounts to be sure.
Why is the required payment not just $5,000 divided by 12?
That simple division ignores interest entirely. Because interest keeps accruing on the balance each month, the actual required payment is higher than balance divided by months, and the gap grows with a higher APR.
Is 12 months a realistic target for most debt?
It depends entirely on the balance, the APR and what payment fits your budget. There is nothing special about a one-year timeline. It is simply a common goal people set for themselves.
