A directory of our calculators to help with simple financial decisions.

This calculator allows you to show a full amortization schedule after you input the Principal, Interest Rate, Term, starting month, and year. It also allows you to model a variety of prepayment options, such as monthly or lump sum, and summarizes the savings.
