A 5/1 ARM is the most popular adjustable-rate mortgage in the U.S., offering a fixed rate for the first 5 years before adjusting annually. The initial rate is typically 0.75%–1.25% below a comparable 30-year fixed, making it attractive for borrowers with a clear 5-year horizon — whether that means selling, refinancing, or paying down principal aggressively.
5/1 ARM rates reflect the initial fixed-rate period. Your rate will adjust after 5 years based on market conditions. Last Updated and Verified: April 8, 2026

Methodology & Data Sources
Direct-Sourced & Verified Rate Data: Every 5/1 ARM rate on this page is sourced directly from the official website of the lending institution. Adjustable-rate mortgage rates reflect the initial fixed-rate period and are verified and updated daily.
Nationwide Lender Coverage: Our database monitors over 8,500 banks and credit unions across all 50 states, capturing a diverse mix of community credit unions, regional banks, and national online lenders. This breadth ensures you see competitive rates that many national rate surveys miss.

Proprietary Lender Safety Ratings: Rate alone is only part of the picture. MonitorBankRates evaluates the financial stability of every listed institution using regulatory FDIC and NCUA data. Our composite Health Grades (A+ to F), Star Ratings, and Texas Ratio calculations give you a clear view of lender stability so you can borrow with confidence from a financially sound institution.
