Here is a calculator that you can use to compute the periodic payment of a loan for the runoff table generator below in case you don't know the payment amount. For example, for a $5000 loan, what is the monthly payment for a loan at 10% interest for 2 years. The principal amount is 5000, there are 12 payments per year if the loan is paid monthly, and a two year loan has 24 monthly payments in total. The calculated payment will be about $230.72 plus fractional cents. If your payment barely covers the interest, your browser may not have enough memory or may appear to hang for a long time. If you payment is less than the interest rate, you will never pay off the loan and an error message is returned. (We don't do negative amortization on loans. It's not a great approach in real life either.)
The calculation performed below is computed from the standard loan formula:
where the annualized percent interest rate is divided by 100 to get the decimal interest rate and further divided by the payments per year to get periodic interest rate i
Also computed is the total cost which is the monthly payment times the total number of payments. The total interest paid over the life of the loan is the total cost minus the original amount that was borrowed.
