I need to review the calculation on a variable rate mortgage tied to the 1-year constant maturity Treasury. The mortgage is a 2/28 FHA originated in 2006, earns interest in arrears and is on a 360/30 day base. Some payments have been made past the due date and some payments different from the contractual payments were made. Based on my review several of the payment changes were not made or were made incorrectly. Do you have a product that can be used to calculate an amortization of a loan with these characteristics for comparison to the data record? If so, please tell me which product.

Yes. Please see the

Time Value of Money calculator. With this calculator, the user has complete control of all events over the entire term of the cash flow. Meaning, you can make payments (or investments) on any date for any amount. Interest rates can be changed on any date as well as the compounding method.There are a lot of options and there are 25 tutorials to assist in learning them. Everyone should try tutorial #1 and you should specifically look at tutorial #25 – tracking loan payments.
