Refinance Calculator
Find out if refinancing your mortgage makes financial sense. Compare your current loan to a new loan to see monthly savings, break-even point, and lifetime interest saved.
When Does Refinancing Make Sense?
- You can lower your rate by at least 0.5–1%
- You plan to stay past the break-even point
- You want to switch from an ARM to a fixed-rate mortgage
- You need lower monthly payments
Frequently Asked Questions
Refinance closing costs typically range from 2%–5% of the loan amount. On a $250,000 loan that's $5,000–$12,500.
Break-even = closing costs ÷ monthly savings. If closing costs are $4,000 and you save $200/month, break-even is 20 months.
