How It Works

The calculator uses the standard amortization balance formula: Balance = P × (1 + r)^k − M × [(1 + r)^k − 1] / r, where P is the original principal, r is the monthly interest rate (annual rate ÷ 12), k is the number of payments already made, and M is the fixed monthly payment computed from the standard formula M = P × r(1 + r)^n / [(1 + r)^n − 1]. The formula captures exactly how compounding interest accumulates while each fixed payment chips away at the balance. The first term represents the grown principal after k periods of compounding; the second term represents the accumulated value of payments made. The difference is the remaining balance.

Examples

Car loan after 2 years
$25,000 at 6%, 5-year term, 24 payments made.
Result: Remaining balance ~$15,800 with 36 payments left.
Mortgage after 5 years
$300,000 at 7%, 30-year mortgage with 60 payments made.
Result: Remaining balance ~$282,000 — minimal principal reduction in the early years.
Personal loan near payoff
$10,000 at 9%, 3-year term, 30 payments made.
Result: Remaining balance ~$2,700 with only 6 payments left.

Frequently Asked Questions

Why does my balance drop slowly at first?
In early payments, most of each payment goes toward interest rather than principal because the outstanding balance is large. As the balance shrinks, more of each fixed payment reduces principal — this is how amortization works. The effect is most noticeable on long-term loans like 30-year mortgages.
Can I use this for a mortgage?
Yes. Enter the original loan amount at closing, the locked interest rate, the full 30-year (or other) term, and the number of monthly payments you have made. The calculator will show the current outstanding balance, matching what your lender would show before any extra-payment adjustments.
Why might this differ from my lender's balance?
This calculator assumes a standard fixed-rate amortizing loan with payments made exactly on schedule. Differences can arise if you have made extra principal payments, had a variable rate adjustment, deferred any payments, or if your lender applies partial-month rounding differently. Use this as a close estimate; your lender's official payoff statement is the authoritative figure.
