Over the life of the loan, payments decrease (decreasing installments), the principal portion remains constant and the interest portion decreases. In this type of amortization the principal paid, not the total payment, remains constant.

Use this calculator to create a printable amortization schedule for a loan that has declining interest and declining payment amounts while principal payments remain constant. This schedule can be for a loan or mortgage with equal **principal** payments. Also called "Fixed principal declining interest loan payment table".

**Payment Amount = Principal Part + Interest Part**

- Loan Amount
- Amount or present value of the loan.
- Interest Rate
- The annual stated rate of your loan. Nominal rate.
- Number of Payments
- The total number of payments, initial or remaining, to pay off the given loan amount.
- Payment Frequency
- Calendar periods that payments will be made. (e.g. Weekly, Monthly, Quarterly, etc.)
- Compounding
- Assumed to be coincide with payments. When payment and compounding frequency do not coincide, first use the Loan Calculator with Compounding and the Interest Rate will be calculated in terms of payments.

More common method to amortize a loan is with constant loan payments.
