How It Works

The refinance break-even calculator helps you determine whether switching your mortgage to a lower interest rate will save you money after accounting for all closing costs. The core calculation divides your total refinancing costs by the monthly payment savings to find the break-even point in months. Before that point, the upfront costs outweigh the savings. After it, every dollar saved goes directly into your pocket.

For example, refinancing a $350,000 loan with 27 years remaining from 7.25% to 6.50% reduces your monthly payment from $2,423 to $2,250 — a saving of $173 per month. With $6,000 in closing costs, your break-even point is 35 months (just under 3 years). Over the remaining 27 years, you will save approximately $50,000 in total interest after closing costs. The monthly payment is calculated using the standard amortization formula that US lenders use, producing a fixed amount that fully repays both principal and interest by the end of the term.

Closing Costs to Factor In

US refinancing closing costs typically range from 2% to 5% of the loan amount. The largest single cost is usually the origination fee (0.5-1% of the loan), followed by title insurance ($500-$3,000 depending on your state and loan amount), appraisal ($400-$700), credit report ($30-$50), recording fees ($50-$250), and various third-party fees. Some lenders offer no-closing-cost refinances where costs are rolled into a slightly higher rate, typically 0.25-0.50% higher. Always request a Loan Estimate from multiple lenders to compare total costs.

When Refinancing Makes Sense

Refinancing is most beneficial when three conditions align. First, the interest rate difference is at least 0.50 to 0.75 percentage points. On a $350,000 loan, a 0.75% reduction saves roughly $173 per month. Second, you have a substantial remaining term, ideally more than 10 years. Third, the break-even period is comfortably shorter than the time you plan to keep the loan. Additionally, refinancing can make sense to switch from an adjustable-rate mortgage (ARM) to a fixed rate for payment stability, to remove PMI by refinancing at a higher LTV, or to shorten your term from 30 years to 15 years.

When Refinancing Does Not Make Sense

Refinancing is not always the right move. If you plan to sell within a few years, the closing costs may exceed the savings. If your credit score has dropped since your original loan, you may not qualify for a better rate. If you have already paid down significant principal on your current loan, resetting the amortization clock with a new 30-year term can cost more in total interest even at a lower rate. Also consider that extending your term means more years of payments. If you are 10 years into a 30-year mortgage, refinancing into a new 30-year means 40 total years of payments unless you choose a shorter term.

How To Use This Calculator

  1. Enter your current loan balance. Check your most recent mortgage statement or online account for the exact outstanding principal amount. This is the amount you still owe, not the original loan amount or home value.
  2. Set your current interest rate from your existing mortgage statement. This is the rate you are currently paying, which determines your current monthly payment.
  3. Enter the new interest rate you have been offered or are considering. Shop rates from at least 3-5 lenders and compare using the APR (annual percentage rate), which includes fees, for a more accurate comparison.
  4. Adjust the remaining loan term to match how many years are left on your current mortgage. A longer remaining term means more potential lifetime savings from a lower rate.
  5. Enter your estimated closing costs. Use 2-5% of your loan balance as a starting point and refine based on actual Loan Estimates from lenders. Include any prepayment penalties from your current loan in the exit fees field.

❓ Frequently Asked Questions

When should I refinance my mortgage?

Consider refinancing when the rate difference is at least 0.50% to 0.75%, you plan to stay in the home long enough to recoup closing costs, and your credit score qualifies you for a better rate. A common rule of thumb is that refinancing makes sense when you can lower your rate by at least 0.5% and your break-even period is under 3 years.

What are the costs of refinancing in the US?

Refinancing closing costs in the United States typically range from 2% to 5% of the loan amount. On a $300,000 refinance, expect $6,000 to $15,000. Common costs include origination fee (0.5-1%), appraisal ($400-$700), title search and insurance ($500-$3,000), credit report ($30-$50), recording fees ($50-$250), and various third-party fees.

What is a no-closing-cost refinance?

A no-closing-cost refinance means the lender covers your closing costs in exchange for a slightly higher interest rate, typically 0.25% to 0.50% higher. You avoid upfront costs but pay more over the life of the loan. This can make sense if you plan to sell or refinance again within a few years, as you avoid paying closing costs you would not fully recoup.

How do I calculate my refinance break-even point?

Divide your total closing costs by the monthly savings from the new lower rate. For example, if refinancing costs $6,000 and your new payment is $200 less per month, your break-even point is 30 months (2.5 years). After that point, every month of savings is pure benefit. Only refinance if you plan to keep the loan past the break-even point.

Can I refinance with bad credit?

Yes, but your options are more limited. FHA Streamline refinances require no credit check if you have an existing FHA loan. Conventional refinances typically require a minimum credit score of 620, though the best rates require 740 or higher. VA Interest Rate Reduction Refinance Loans (IRRRLs) also have relaxed credit requirements for eligible veterans.

What is a cash-out refinance?

A cash-out refinance replaces your existing mortgage with a larger loan, giving you the difference in cash. For example, if you owe $200,000 on a home worth $400,000, you could refinance for $300,000 and receive $100,000 in cash. Rates are typically 0.125% to 0.5% higher than a standard rate-and-term refinance, and most lenders cap cash-out at 80% LTV.

Will refinancing affect my credit score?

Refinancing can cause a temporary dip of 5-10 points due to the hard credit inquiry and new account. However, if you rate-shop within a 14-45 day window (depending on the scoring model), multiple mortgage inquiries count as a single inquiry. Your score typically recovers within a few months of consistent payments on the new loan.

How much can I save by refinancing?

Savings depend on the rate difference, loan balance, and remaining term. Reducing your rate by 0.50% on a $350,000 loan with 25 years remaining saves roughly $105 per month or $31,500 over the loan life. A 1.00% reduction saves around $210 per month or $63,000 total. Always subtract closing costs to calculate your net savings.

Should I refinance from a 30-year to a 15-year mortgage?

Refinancing from a 30-year to a 15-year mortgage can save a massive amount in interest, but your monthly payment will increase significantly. On a $300,000 balance, switching from a 30-year at 7.0% ($1,996/mo) to a 15-year at 6.0% ($2,532/mo) increases your payment by $536 but saves you over $200,000 in total interest.

What is the difference between rate-and-term and cash-out refinancing?

A rate-and-term refinance changes your interest rate, loan term, or both without taking additional cash. A cash-out refinance lets you borrow more than you owe and pocket the difference. Rate-and-term refinances typically get better rates and lower closing costs because they are considered lower risk by lenders.
