What to Know About 30-Year Fixed Mortgages

A 30-Year Fixed fixed-rate mortgage locks in your rate at 7% for the entire 30-year term. Your principal and interest payment never changes, making budgeting predictable.

  • Lower monthly payments. A 30-year term spreads payments out, keeping monthly costs manageable.
  • Interest costs matter. On $400,000, a 30-Year Fixed costs $446,428 in total interest. Shorter terms save significantly on interest.
  • Rate lock timing. Lock your rate when you find a good deal — rates can change daily. Most locks last 30-60 days.
  • Extra payments help. Even on a 30-year term, making one extra payment per year can shave years off your mortgage and save thousands in interest.
