Use this amortization schedule calculator to create a printable table for a loan or mortgage with fixed principal payments. The amortization schedule shows - for each payment - how much of the payment goes toward the loan principal, and how much is paid on interest.
This page opens with a focused preset flow. Keep loan term units set to Payments. Keep payment frequency: set to Monthly.
What This Tool Does
The amortization schedule calculator equal principal payments is built for people who want a fast answer and a clearer understanding of what affects the final output.
It works best when you enter realistic values for Loan Amount: $, Interest Rate: %, Number of Payments:, Loan Term Units. If the tool includes select boxes or toggles, choose the scenario that matches your use case before you calculate.
Loan Payment = Principal Amount + Interest Amount
With a fixed principal loan, loan payment amounts decrease over the life of the loan. The principal amount included in each payment stays the same but the interest amount decreases over each payment period.
Helpful variable notes from the matched source page: Loan Amount: The size or value of the loan.; Interest Rate: The annual stated rate of the loan.; Number of Payments: The total number of payments, initial or remaining, to pay off the given loan amount.
The core formula used by this calculator is \text{Principal Payment} = \frac{P}{n}. Reviewing it can help you validate the output and understand how the variables interact.
