Plain-English guide
Terms & how it works
Confused by a field? Read the short definitions here while you use the tool.
Loan Balance
The amount you borrowed (or still owe). Interest is charged on this balance.
Annual Interest Rate (%)
APR — the yearly interest rate. We convert it to a monthly rate (APR ÷ 12) inside the math.
Remaining Term (months)
How many months the loan is scheduled to run. Longer terms usually mean smaller payments but more total interest.
Extra Monthly Payment
Optional dollars paid above the required payment. This hits principal early and shortens payoff.
- M
Monthly payment
Fixed installment covering interest and principal.
- P
Principal
Amount borrowed or remaining balance.
- r
Monthly rate
Annual APR ÷ 12 ÷ 100.
- n
Term (months)
Number of scheduled payments.

How to Calculate Student Loan Payoff Step-by-Step

Governing formula
M = P · r(1+r)^n / ((1+r)^n − 1)
Student loan payoff under a fixed schedule; extra payments accelerate freedom from debt.
Example: set Loan Balance ($) = 35,000, Annual Interest Rate (%) = 5.5, Remaining Term (months) = 120, then read the result.

Amount borrowed or remaining balance.
- r
Monthly rate
Annual APR ÷ 12 ÷ 100.
