Fixed vs Adjustable Rate
Fixed-Rate Mortgages
Same rate for the entire term. Payment never changes (escrow may adjust). Most common: 15 and 30 years. Best for long-term homeowners and when rates are low.
Adjustable-Rate Mortgages (ARMs)
Lower initial rate for 5-10 years, then adjusts annually. A "5/1 ARM" = 5 years fixed, adjusts yearly. Usually 0.5-1% lower initially. Best for people who'll move or refinance before adjustment.
The Math
On $300K, a 0.75% lower initial rate saves ~$150/month for the fixed period. But after adjustment, rates can rise 2% per year up to a 5-6% lifetime cap. Model both scenarios with our mortgage calculator.

For the most accurate results, use the interest rate from your actual loan offer or pre-approval letter rather than advertised rates, which may require specific credit scores or down payment amounts to qualify for. Also factor in any fees, points, or closing costs that are not reflected in the base interest rate, as these increase your effective cost of borrowing.
