Try it now, free. Adjustable Rate Mortgage Calculator: Estimate Your ARM Payment Instantly An adjustable rate mortgage calculator estimates your monthly payment during the fixed introductory period of an ARM and projects how it may change once the rate begins adjusting. On CalQora's ARM calculator, you enter home price, down payment, initial rate, ARM type (like 5/1 or 7/6), and adjustment caps to see both your starting payment and a worst-case future scenario. How ARM Payments Are Calculated An ARM starts with a fixed rate for a set number of years—5, 7, or 10 are common—then adjusts based on a market index (such as SOFR) plus a lender margin, which typically ranges from 2% to 3.5%. As of July 2026, the national average 5/1 ARM rate sits around 6.5%, often lower than a comparable 30-year fixed loan during the intro period. After that period ends, rate caps limit how much your payment can rise: an initial cap (often 2-5%), a periodic cap for each later adjustment (usually 1-2%), and a lifetime cap on the maximum total increase. Understanding these caps is essential to knowing your true worst-case monthly payment. What CalQora's Calculator Includes * Initial fixed-period payment (principal, interest, taxes, insurance) * Estimated adjusted payment based on index + margin * Initial, periodic, and lifetime rate cap modeling * Side-by-side comparison against a 30-year fixed payment * Break-even timeline for refinancing before adjustment Try the full breakdown on the CalQora ARM Calculator or compare loan types in our mortgage calculator suite, including fixed-rate, FHA, VA, and USDA options. Quick Answer (FAQ) Is an ARM cheaper than a fixed-rate mortgage? Usually yes, during the initial fixed period, since ARMs typically launch with a lower starting rate. After that period, your rate can rise or fall with the market. What do ARM numbers like 5/1 or 7/6 mean? The first number is the years the rate stays fixed; the second is how often it adjusts afterward (in years or every six months). Is an ARM calculator accurate? It gives a solid estimate of your starting and worst-case payments, but actual adjustments depend on market index movement. Always review your loan's specific cap structure with your lender.
