Is a 20-year term right for you?

A 20-year term splits the difference: a meaningfully lower payment than a 15-year, with interest savings that still dwarf the 30-year. Underrated, and worth pricing whenever you get quotes.

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.

Can I switch terms later?
Not on the same loan — but you can refinance into a different term, or simply prepay a longer loan on a shorter schedule. Prepaying keeps the lower required payment as a safety net, which many borrowers prefer.
