Is a 15-year term right for you?

The 15-year is the most popular short term for a reason: rates are typically the lowest on the board, total interest is less than half of a 30-year's, and the finish line is visible from day one.

Compare this term directly against the default with the 30-year fixed calculator, or run any term in the main payment calculator.

Term is a budget decision first

Whatever term tempts you, run it through the affordability calculator with your real income and debts. A shorter term you can sustain beats an aggressive term that forces you to skip retirement savings or carry credit-card balances at 25% to make the house payment.
