What you're looking at
These are today's par rates with our standard compensation built into the APR — what you'd actually close at, not a teaser rate. Points and fees are included in the APR so you can compare apples to apples.
If your current rate is above 6.5%, the math on a refinance is probably worth running. If it's below 5%, usually not — unless you're taking cash out or shortening the term.
Closing costs run $3,000–$5,000 on a typical refinance. Divide that by your monthly savings to get your break-even. The refi analyzer runs that math for you.
