Common ARM Structures
Popular ARM terms: 5/1 ARM (fixed 5 years, adjusts annually), 7/1 ARM (fixed 7 years), 10/1 ARM (fixed 10 years). Initial rates typically 0.5-1.5% below comparable fixed rates.
ARM Interest Rate Calculation
After the initial period, new rate = Index Rate + Margin, subject to periodic and lifetime caps. Common indices: SOFR (Secured Overnight Financing Rate), Treasury yields. Margins typically 2-3%.

When ARMs adjust, monthly payments can increase by hundreds of dollars. A $300,000 ARM at 4% costs $1,432/month. If it adjusts to 6%, payments jump to $1,799—a $367 increase. Budget for worst-case scenarios.
