AZ5 - Calculate True Interest Rate for a Mortgage V2.6 12-9-1992 Calculate the true interest rate when given the amortization of a loan or regular annuity. Useful for 'Truth in Lending' calculations. AZ5 accepts input in the forms normally associated with a real estate loan. This program allows a final or 'BALLOON' payment of a different amount from the regular payment to be entered. If there is no ballon payment, enter the regular payment value for the balloon payment value. Input values are: Loan Amount - The loan amount in dollars and cents. Do not use commas or dollar signs. Decimals are permitted. Lender Discount Points - The number of discount percentage points charged by the lender. Other Truth in Lending Costs - Any other amount in dollars and cents charged or deducted by the lender you want to include. Number of Payments Including Balloon - Enter the number of payments including the balloon payment; i.e. a 30 year loan with 12 payments a year is a 360 payment loan. Payments per Year - A loan with monthly payments has 12 payments per year. ...quarterly has 4 payments per year. etc. Regular Payment Amount - Payment amount in dollars and cents. Balloon Payment Amount - Balloon payment (one time payment at the end of a loan) amount in dollars and cents. This program solves the present value equation for the true interest rate and gives the answer as a percentage. If you desire hard copy, use the print screen function on your computer.
