How the Loan Balance Calculator works
On an amortized loan, your original payment is fixed, but the mix of principal and interest inside
each payment shifts every month. This calculator rebuilds your full original amortization schedule
and reads off the balance at the exact month you specify, so you can see where you stand today
without pulling up a statement.
It also separates out how much of your payments so far went to principal versus interest — useful
for understanding how much progress you've actually made against the loan.
Each month: Interest = Balance × r; Principal Paid = Payment − Interest; New Balance = Balance − Principal Paid applied month by month, starting from the original loan amount
If you've made any extra payments beyond your regular schedule, your real balance will be lower
than this estimate — see our Extra Payment Loan Calculator to model that case.
Frequently asked questions
Amortized loans front-load interest, so early payments reduce principal more slowly than later payments do. Because of this, your balance drops more slowly than the calendar would suggest during the first half of the loan.
It should be very close, but small differences can appear due to rounding, the exact day payments were applied, or fees your servicer may have added. Use your official statement for anything beyond planning purposes.
This calculator assumes only the standard scheduled payment was made each month. If you've made extra payments, your actual balance will be lower than shown here — try our Extra Payment Loan Calculator to model that instead.
