ARM vs Fixed Rate Mortgage Calculator

Compare total cost of a 5/1, 7/1, or 10/1 ARM vs 30-year fixed mortgage across different rate-adjustment scenarios.

Quick answer: An ARM can save money if the lower starting rate outweighs future adjustment risk. A fixed mortgage wins when payment certainty or rising-rate risk matters more.

About mortgage rates

Mortgage rates depend on loan type (30-yr fixed, 15-yr fixed, ARM, FHA, VA, jumbo), your credit score, down payment, points paid, loan amount, property state, and whether you're purchasing or refinancing. The calculator above uses a representative market rate for payment estimates — your actual rate will vary.

For a personalized rate comparison, use the tool below to see lenders ranked by APR, loan type, and your profile.
