Refinance Break-Even Calculator
Calculate how many months until your refinance pays for itself. Know when it makes sense to refinance your mortgage.
How to Use the Refinance Break-Even Calculator
This calculator helps you determine whether refinancing your mortgage makes financial sense based on your specific situation. By comparing your current mortgage terms with a potential new loan, you'll see exactly how long it takes to recoup your closing costs and start actually saving money.
What You'll Need
- Current loan balance — The remaining principal on your existing mortgage
- Current interest rate — Your existing mortgage's annual percentage rate
- Months remaining — How many months are left on your current loan
- New interest rate — The rate offered on the refinanced loan
- Closing costs — Total fees for the new loan (typically 2-5% of loan amount)
Understanding Your Break-Even Point
The break-even point is the moment when your cumulative monthly savings equal the closing costs you paid to refinance. Before this point, you're still "paying back" the refinance costs. After this point, every dollar saved goes straight to your pocket.
The formula is straightforward:
Break-Even Months = Closing Costs ÷ Monthly Savings
When Does Refinancing Make Sense?
Refinancing typically makes sense when:
- You'll stay past break-even — Plan to stay at least 1-2 years beyond your break-even point
- Rate drop of 0.5-1%+ — Smaller drops can still work with low closing costs
- You have a large balance — Bigger loans mean more savings per rate point
- Your credit has improved — Better scores unlock better rates
- You want to change terms — Switch from 30-year to 15-year, or vice versa
Refinance Closing Costs Explained
Understanding what goes into closing costs helps you negotiate and budget:
- Origination fee: 0.5-1% of loan amount
- Appraisal: $300-600
- Title insurance & search: $500-1,500
- Credit report: $25-50
- Recording fees: $50-250
- Prepaid items: Property taxes, insurance escrow
Frequently Asked Questions
The refinance break-even point is the number of months it takes for your monthly savings from a lower interest rate to equal the total closing costs you paid to refinance. After this point, you start actually saving money from the refinance.
Break-even months = Total Closing Costs ÷ Monthly Savings. For example, if your closing costs are $4,000 and you save $200/month, your break-even point is 20 months. After 20 months, every dollar saved is money in your pocket.
You should plan to stay in your home longer than your break-even period. If your break-even is 18 months, staying at least 2-3 years (24-36 months) ensures you realize significant savings. The longer you stay past break-even, the more you benefit.
Typical refinance closing costs include: loan origination fees (0.5-1% of loan), appraisal fees ($300-600), title insurance and search ($500-1,500), credit report fees, recording fees, and prepaid items like property taxes and insurance. Total costs typically range from 2-5% of the loan amount.
Whether a 0.5% rate reduction is worth it depends on your loan balance and how long you'll stay. On a $300,000 loan, a 0.5% reduction saves roughly $90/month. If closing costs are $4,000, your break-even is about 44 months. Use this calculator to determine if it makes sense for your specific situation.
