Debt-Free Date Calculator
Example: Current balance: 18000 $ · Annual interest rate (APR): 19.99 % · Months until your target payoff date: 36 months
| Monthly payment required to hit your date | $669 |
| Total interest at your target date | $6,079 |
| Extra payment needed above current minimum | $368 |
| Total paid to reach your date | $24,079 |
Worked example
Clearing $18,000 at 19.99% APR in exactly 36 months requires a monthly payment of about $668. Over those 3 years you pay roughly $6,048 in interest and $24,048 in total. The current minimum payment (at 2% of balance) is about $360, so you need an extra $308 per month to hit that date. That $308 difference — about $10 a day — is the price of a three-year timeline versus an open-ended one.
Frequently asked questions
What if my target date requires a payment I cannot afford?
Set a payment you can actually make, then use the calculator to find the resulting payoff month. You can also work backwards: enter several target months until the required payment fits your budget. Even a modest increase over the minimum dramatically shortens the timeline and saves substantial interest.
What happens if I miss a payment month?
A missed payment in any given month means the balance carries forward at interest, pushing the payoff date out by roughly the equivalent of that month plus the interest accrued. If you miss one payment, add it as an extra payment as soon as possible to keep the target alive.
Should I use this for all my debts together or one at a time?
For the clearest picture, use this tool for each debt individually. If you are following the avalanche or snowball method, apply the required payment to the priority debt and minimum payments to the others, then recalculate as each debt is cleared and its payment is rolled into the next.
How does a balance transfer interact with this target?
If you transfer the balance to a 0% promotional card, your required payment drops because no interest accrues during the promo. Rerun this calculator with a 0% rate for the promo months remaining — the required monthly payment will be simply (remaining balance ÷ remaining months), often much lower than your current rate would suggest.
