How does a variable interest rate loan affect my payments?

With a variable interest rate loan, your payments change as interest rates fluctuate. The rate is typically tied to a benchmark index like the prime rate or SOFR, plus a margin set by the lender. When the index rises, your interest rate and monthly payment increase. When it falls, your payment decreases. This means your payments are unpredictable over time, which can make budgeting harder. You might start with a lower rate than a fixed loan offers, which is the main appeal, but you take on the risk of rates climbing significantly. Many variable rate loans have caps that limit how much the rate can increase per period or over the life of the loan, which provides some protection.
