In plain English — what does this do?
🏠 You want to buy something big (like a house or car) but you don’t have all the money right now. A bank gives you the money today, and you pay it back little by little every month. This tool tells you ‘how much do I pay each month?’
A refinance calculator helps you decide whether refinancing your existing loan makes financial sense. It compares your current monthly payment to the new payment, calculates how many months it takes to recoup closing costs (break-even point), and shows total lifetime savings over the new loan term.

❓ Common questions
- When does refinancing make sense?
- Refinancing typically makes sense when you can lower your rate by at least 0.5–1%, you plan to stay in the home past the break-even point, and closing costs are reasonable relative to savings.
- What are typical refinance closing costs?
- Closing costs typically run 2–5% of the loan amount, covering appraisal, title search, origination fees, and other charges. Some lenders offer no-cost refinancing by rolling fees into the rate.
- Does refinancing restart my amortization?
- Yes, if you take a new 30-year term you restart the amortization clock, meaning more of your early payments go to interest again. A shorter new term avoids this but raises monthly payments.
- What is a cash-out refinance?
- A cash-out refinance replaces your existing loan with a larger one, giving you the difference as cash. This calculator covers rate-and-term refinancing only.
- How does a shorter new term affect savings?
- A shorter new term may increase monthly payments but reduce total interest substantially. Compare break-even and lifetime savings with both 15-year and 30-year scenarios.
