How the Amortization Calculator Works

It builds a payment-by-payment schedule showing how each mortgage payment splits between interest and principal, and how your balance falls to zero over the life of the loan.

How It Works, Step by Step

The calculator computes a fixed monthly payment, then walks the loan forward month by month. Each period it charges interest on the remaining balance, applies the rest of the payment to principal, and reduces the balance — repeating until the loan is paid off.

An amortization schedule covers only principal and interest, so it looks the same in Florida as anywhere else for a given loan. What differs is your escrow: Florida property taxes and insurance are collected on top of the amortized payment, so your actual monthly total will exceed the figure on the schedule.
