Loan Payoff Time Calculator

A balance and a payment are enough to answer the question that matters most about a debt: when does it end? The answer is frequently far longer than expected, particularly on revolving balances where the required payment is a small percentage.

This calculator solves for the number of payments, reports the total interest along the way, and tells you plainly when a payment is too small to ever clear the balance.

Result

Payments to clear

44 months

Total interest

$4,154

Time to clear: 3.7 years
Payoff date: 2029-11-01
Total paid: $13,154
Interest share of total: 31.58%

The final payment is normally smaller than the others because only the remaining balance is due.

This assumes the rate stays fixed and no new charges are added to the balance.

Worked examples

Every figure below is produced by running this calculator against the example inputs, so the numbers always match the tool.

A card balance at a fixed payment

$9,000 at 21.9% paid at $300 a month from April 2026.

Payments to clear: 44 months
Total interest: $4,154
Payoff date: 2029-11-01

The same balance at $450 a month

A 50% larger payment on identical terms.

Payments to clear: 26 months
Total interest: $2,300
Interest share of total: 20.35%

Small payments barely move the balance

At 21.9% a $9,000 balance accrues around $164 of interest in the first month. A $200 payment reduces the balance by $36; a $300 payment reduces it by $136 - nearly four times as much for fifty percent more money.

That non-linearity is why increasing a payment modestly shortens a debt dramatically, and why minimum payments on revolving balances can run for decades.

When a payment never clears the balance

If the payment is less than the monthly interest, the balance grows regardless of how long you pay. The calculator detects that and reports the interest-only amount rather than producing a meaningless number.

That figure is worth knowing on any high-rate balance: it is the line below which payments accomplish nothing at all.

Methodology and assumptions

What this calculator does, and what it deliberately does not do.

The number of payments is solved from the balance, the periodic rate and the payment.
The schedule assumes a fixed rate, no new charges added to the balance, and every payment made on time.
The final payment is normally smaller because only the remaining balance is due.

Frequently asked questions

Does this work for credit cards?

For a fixed payment on a balance with no new spending, yes. Minimum payments that fall as the balance drops behave differently and take considerably longer.

What if I add new charges?

The calculation assumes none. Any new spending extends the payoff, which is why balance transfers frequently fail to help.

Why does a small increase help so much?

Because the interest portion is fixed by the balance. Every extra dollar goes entirely to principal, and reduces every future month of interest.

Is the payoff date exact?

It assumes payments on the same day each month at a fixed rate. Real timing and variable rates shift it slightly.
