How the mortgage comparison calculator works

Start with the amount you expect to borrow, which is the purchase price minus your down payment. Then enter the terms you are weighing. Most people compare 15, 20 and 30 years, but you can put in whatever combination you are considering.

Each term needs its own interest rate, because shorter terms are usually priced lower than longer ones. Use current mortgage rates rather than the same rate across all three, or the comparison will understate how much the shorter term helps.

The results compare principal and interest only. Your real monthly payment will also include property taxes and homeowners insurance, and mortgage insurance if your down payment is under 20 percent. For a fuller estimate of a single loan, use the mortgage calculator instead.
