Follow along with an example to see how the loan balance calculator works.

After 5 years on a 30-year mortgage:
Learn the math behind the loan balance formula to make informed decisions about your loan.
Remaining Balance = P × [(1 + r)^n - (1 + r)^p] / [(1 + r)^n - 1]
P = Original loan principal
r = Monthly interest rate (annual rate ÷ 12)
n = Total number of payments
p = Number of payments made
The formula accounts for the fact that:

To calculate your remaining loan balance, enter your original loan amount, interest rate, loan term, and period. The calculator will apply the amortization formula and subtract the paid-off principal from the original amount to tell you how much of the loan is left. Early payments mostly go toward interest, which is why the remaining balance falls slowly at first.
The formula for calculating remaining loan balance is: Remaining Balance = P × [(1 + r)^n - (1 + r)^p] / [(1 + r)^n - 1] P = Original loan principal r = Monthly interest rate (annual interest rate ÷ 12) n = Total number of payments (loan term in months) p = Number of payments made The formula takes into account that early payments are mostly interest and later payments are mostly principal.
Interest affects your loan balance in two ways: 1) In the early years of the loan, most of your payment is interest. As a result, your remaining balance decreases slowly. 2) As time passes, more of each payment goes toward the loan principal. The remaining balance decreases faster as time passes. The higher your interest rate, the more of your payment goes toward interest vs. principal. The higher your interest rate, the more you pay in total over the life of the loan.
You can usually pay off your loan early, but make sure your loan agreement doesn’t include prepayment penalties. The earlier you pay off a loan, the more interest you can save. Use the loan payoff calculator to see how much you still owe. Consider making extra payments or a lump sum payment.
Principal is the original amount of the loan that you borrow. Interest is the cost of borrowing the principal. In the early years of a loan, most of your payment is interest. As time passes, more and more of your payment is applied to the loan principal.
