When does refinancing make sense?

Refinancing typically makes sense when: (1) you can lower your rate by at least 0.5-1%, (2) you plan to stay in your home past the break-even period, and (3) your credit score has improved since your original loan.

What are typical refinancing closing costs?

Closing costs typically range from 2-5% of the loan balance, including lender fees, title insurance, appraisal, and prepaid items. On a $300,000 loan, expect $6,000-$15,000 in closing costs.

Should I refinance to a shorter term?

Refinancing from a 30-year to a 15-year mortgage increases monthly payments but can save tens of thousands in interest and build equity faster. Calculate whether the higher payment fits your budget.

Can I roll closing costs into the refinance?

Yes, most lenders allow you to add closing costs to the loan balance (called a no-closing-cost refinance). This eliminates upfront costs but increases your loan balance and monthly payment.

Mortgage Refinance Break-Even Calculator

Refinancing your mortgage can be a powerful way to reduce your monthly payment, pay off your loan faster, or tap into your home equity. But refinancing isn’t free—closing costs can run from 2% to 5% of your loan balance, which means you need to stay in your home long enough to recoup those costs through monthly savings. The Mortgage Refinance Break-Even Calculator tells you exactly when that happens.

What Is the Break-Even Point for Refinancing?

The break-even point is the number of months it takes for your cumulative monthly savings to equal your upfront closing costs. After the break-even, every month you stay in your home, you come out ahead.

Break-even (months) = Closing Costs / Monthly Savings

Where Monthly Savings = Current Monthly Payment - New Monthly Payment

Your new monthly payment is calculated using the standard amortization formula:

M = P × [r(1+r)^n] / [(1+r)^n − 1]

Where P = loan balance, r = new monthly rate, n = new term in months.

Lifetime Interest Saved

Beyond the monthly picture, refinancing can dramatically reduce your total interest paid over the loan’s life—especially if you can lower your rate by a full percentage point or more. The calculator shows:

Lifetime Savings = (Current Total Payments - New Total Payments) - Closing Costs

How to Use This Calculator

Enter your current loan balance — The remaining principal on your mortgage.
Enter your current APR — The rate on your existing mortgage.
Enter remaining years — How many years are left on your current loan.
Enter the new APR — The rate being offered for the refinanced mortgage.
Set the new term — Typically 15 or 30 years; a shorter term builds equity faster but increases payments.
Enter closing costs — Request a Loan Estimate from the lender. Typical costs include origination fee, title insurance, appraisal, and prepaid interest.

Examples

Example 1: Classic Rate-and-Term Refinance

Current situation: $300,000 balance at 7.5% APR with 25 years remaining. New offer: 6.0% APR on a 30-year mortgage. Closing costs:$ 3,000.

Current payment: ~$2,218/month
New payment: ~$1,799/month
Monthly savings: ~$419/month
Break-even: 3,000 / 419 ≈ 8 months
With 25 years remaining, break-even occurs well within the remaining term → worth refinancing

Example 2: Shortening the Term

Current: $250,000 at 6.5% APR, 20 years remaining. New offer: 5.25% APR on a 15-year mortgage. Closing costs:$ 4,000.

Current payment: ~$1,863/month
New payment: ~$2,013/month ← higher payment!
Monthly “savings”: −$150/month
The 15-year mortgage costs more per month but saves dramatically on total interest

In this case, the lower rate + shorter term isn’t about break-even on monthly payments—it’s about building equity faster and saving $80,000+ in total interest. Confirm you can afford the higher payment.

Example 3: No Break-Even Scenario

Current: $180,000 at 5.0% APR, 5 years remaining. New offer: 4.5% APR on a 30-year mortgage. Closing costs:$ 5,000.

Monthly savings: ~$350/month
Break-even: ~14 months
But resetting from 5 years to 30 years means dramatically more total interest paid
This refinance is not recommended despite the short break-even

FAQ

Q: What counts as a closing cost when refinancing? A: Typical refinancing closing costs include: origination fee (0.5-1% of loan), appraisal ( $300-$ 500), title insurance ( $1,000-$ 2,000), recording fees, prepaid property taxes and insurance, and discount points if purchased.

Q: What is a no-closing-cost refinance? A: Lenders offer no-closing-cost options either by rolling costs into the loan balance (increasing your debt) or by offering a slightly higher interest rate in exchange for lender credits that cover the costs. Neither is truly “free”—evaluate the tradeoff carefully.

Q: How much should my rate drop to justify refinancing? A: The old rule of thumb was “refinance if rates drop 1%.” Today, the better answer is to calculate your specific break-even and compare it to how long you plan to stay. Even a 0.5% rate drop can be worth it if your break-even is only 18 months and you’re staying 10 more years.

Q: Does my credit score affect refinance rates? A: Yes. Mortgage rates are highly sensitive to credit scores. A score of 760+ typically qualifies for the best rates. Every 20-point drop below 760 adds approximately 0.25% to your rate. If your credit has improved since you took your original loan, you may qualify for a significantly better rate.

Q: Can I refinance if I’m underwater on my mortgage? A: If you owe more than your home is worth, standard refinancing is difficult. However, government programs like the FHFA’s Enhanced Relief Refinance may be available. Check with your servicer or the CFPB.
