## Fixed principal payment calculator help...

A fixed principal payment loan has a declining payment amount. That is, unlike a typical loan, which has a level periodic payment amount, the principal portion of the payment is the same payment to payment, and the interest portion of the payment is less each period due to the declining principal balance. Thus the payment amount declines from one period to the next. Ultimately, the borrower will pay less in interest charges with this loan method.

This calculator will solve for any one of four possible unknowns: "Amount of Loan," "Number of Payments" (term), "Annual Interest Rate" or the "Periodic Payment."

Enter a '0' (zero) for one unknown value.

The term (duration) of the loan is a function of the "Number of Payments" and the "Payment Frequency." If the loan is calling for monthly payments and the term is four years, then enter 48 for the "Number of Payments." If the payments are made quarterly, and the term is ten years, then enter 40 for the "Number of Payments."

Normally you would set the "Payment Method" to "Arrears" for a loan. Arrears means that the monies are lent on one day, and the first payment isn't due until one period after the funds are received.

If the first payment is due on the day the funds are available, then set "Payment Method" to "Advance." This is typical for leases.

Where can I get an amortization schedule for an interest free personal loan with a fixed monthly payment?

## Karl says:

You can use this amortization calculator.

Normally, setting one of the 4 main inputs (loan amount, number of payments, interest rate or payment amount) to zero causes the calculator to solve for that input.

In your case, since there’s no interest, the interest rate is 0.0%, and you’ll not want the calculator to solve for a rate.

Therefore, look at the "amortization method" and select "No Interest".(Then you can enter zero for the interest rate.)

Hope this helps.
