Refinance Savings Calculator
Estimate your new monthly payment, break-even point, and lifetime impact before you refinance.
How to use this home loan refi calculator
A refinance can lower your monthly payment, reduce your interest rate, shorten your loan term, or let you access cash from your home equity. But the right decision depends on the numbers. This calculator helps you quickly compare your current mortgage to a potential refinance.
Enter your remaining balance, current rate, and years left on your existing loan. Then add the new refinance terms, including closing costs and any cash-out amount. You’ll instantly see payment differences, total interest changes, and a break-even estimate.
What the calculator shows
- Current monthly principal + interest payment
- New estimated monthly principal + interest payment
- Monthly savings (or increase)
- Total remaining interest for your current loan
- Total interest for the new refinance loan
- Estimated break-even months based on closing costs and payment change
Interpreting your refinance results
1) Monthly payment is lower, but term is longer
This is common. A lower payment can improve monthly cash flow, but extending the loan term may increase how much interest you pay over time. Lower payment does not always mean lower total cost.
2) Monthly payment is similar, but total interest drops
This often happens when you refinance into a shorter term or significantly lower rate. It can be a strong long-term move if your budget can support the payment.
3) Break-even period matters if you might move soon
If your closing costs are high and your monthly savings are modest, it could take years to recover refinance costs. If you plan to sell or relocate before break-even, refinancing may not be worthwhile.
When refinancing may make sense
- Your new rate is materially lower than your current rate.
- You can recover closing costs in a reasonable time.
- You want to switch from adjustable-rate to fixed-rate stability.
- You want to eliminate mortgage insurance (if eligible).
- You can shorten your term and still afford the payment.
When refinancing may not be ideal
- You’re likely to move before break-even.
- You need to stretch back to a long term and pay much more interest overall.
- Your credit profile results in a rate that is not better than your current loan.
- Fees and points outweigh realistic savings.
Tips for getting a better refinance outcome
Shop at least 3 lenders
Mortgage pricing can vary more than most homeowners expect. Compare APR, not just rate, and ask for a lender fee breakdown.
Compare multiple term options
Run this calculator with 15-, 20-, and 30-year options. A 20-year term can sometimes balance payment comfort and long-term savings.
Decide how to handle closing costs strategically
Paying closing costs upfront usually lowers total interest over time. Rolling costs into the loan preserves cash today but increases loan principal.
Use cash-out carefully
Cash-out refinancing can be useful for consolidating high-interest debt or funding value-adding home improvements. But remember: you are turning short-term expenses into long-term mortgage debt.
