Refinancing · Rate-and-term
When is refinancing worth it?
TL;DR: A refinance may be worth considering if you expect to keep the loan long enough for monthly savings to cover closing costs. Break-even months equal closing costs divided by monthly savings. A longer loan can lower your payment while increasing total interest, so break-even is only one part of the comparison.
A refinance has closing costs, and a lower monthly payment does not offset those costs immediately. The break-even calculation estimates how long that takes. A full comparison also considers the loan balance, repayment timeline and total interest.
What is the break-even point on a refinance?
Your break-even point is the number of months until your accumulated monthly savings equal the costs of getting the new loan, excluding prepaids and escrow deposits for expenses you would pay anyway. Before that month, the refinance is still paying itself off. After it, the savings are generally yours.
How do you calculate it?
Three steps, with your own numbers:
Total your closing costs. Your Loan Estimate lists closing costs as Total Closing Costs. For this calculation, exclude prepaids and escrow deposits for costs you would pay with or without a refinance. Count the costs of getting the loan, including any optional points, after lender credits. Third-party charges such as an appraisal, a professional estimate of your home's value, are distinct from the lender's work, including underwriting, the lender's review of your finances and property. Your quoted rate depends on factors including loan-to-value (LTV), your loan balance divided by your home's value, and debt-to-income (DTI), your monthly debt payments compared with your monthly income.
No lender fees. Zero points required.* Third-party and prepaid costs (appraisal, credit, title, recording, and interest from closing to your first payment) still apply.
Points are optional upfront charges paid to get a lower interest rate.
*Athena charges no origination, application, processing, underwriting, or rate-lock fee. The rate we quote requires no discount points; you may choose to buy your rate down for an additional charge. You'll still pay third-party and prepaid closing costs — appraisal, credit, title, recording, and interest from closing to your first payment. Your rate depends on credit, loan amount, LTV, DTI, and market conditions at lock.
Third-party and prepaid costs can include appraisal, credit, title, recording, tax service and prepaid interest. Your Loan Estimate itemizes the amounts for your loan.
Estimate your monthly savings. Subtract the new monthly principal-and-interest payment from the current one. Principal repays the amount borrowed; interest is the charge for borrowing it. Leave property taxes and insurance out of both figures, since refinancing generally does not change those costs.
Divide. Closing costs (excluding prepaids) ÷ monthly savings = months to break even.
Three scenarios to make it concrete with round numbers (hypothetical example, not an offer or a quote):
| Closing costs (excluding prepaids) | Monthly savings | Break-even | |
|---|---|---|---|
| Clear case | $3,500 | $250 | 14 months |
| Middle case | $4,500 | $150 | 30 months |
| Thin case | $4,500 | $60 | 75 months — over 6 years |
The scenarios only differ in dollars, but they lead to very different decisions. Someone planning to stay put for years can clear a 14-month break-even easily. A 75-month break-even means betting on staying — and on not refinancing again — for over six years before seeing a dollar of real benefit.
What the break-even math leaves out
A longer loan can lower the payment because the balance is spread over more years. For example, after paying down a mortgage for years, refinancing into a new, longer loan can reduce the monthly payment while increasing the total interest paid. Compare the remaining balance, loan length and total interest as well as monthly payments.
Financing closing costs adds those costs to the loan balance and means paying interest on them. Break-even also assumes you keep the loan long enough to reach it. Use the calculation alongside the balance and total-interest comparison.
When is refinancing usually not worth it?
Monthly savings may not cover the costs if you sell or refinance again before break-even, or if the savings are small relative to the costs. Extending a nearly paid-off loan can also increase total interest despite a lower payment. These are reasons to compare the full figures for your situation.
Frequently asked questions
What counts as closing costs on a refinance?
Your Loan Estimate separates the costs of getting the loan from prepaids and escrow deposits.
Costs to get the loan: appraisal, credit report, title, tax service and recording charges, plus any optional points, after lender credits. These belong in the simple break-even calculation. Athena's fee disclosure appears in the "Total your closing costs" step.
Prepaids and escrow deposits: interest collected in advance, property taxes and home insurance, plus money set aside to pay future tax and insurance bills. Exclude these from the simple calculation where they cover expenses you would pay with or without a refinance. They still affect the cash due at closing. A refund of the old loan's remaining escrow balance can offset the new deposit, but the amounts and timing may differ.
Your Loan Estimate itemizes the amounts for your loan.
Does checking my numbers affect my credit?
At Athena, checking your options uses a soft credit pull and does not affect your credit score. If you continue the application, Athena requests a full credit report from one or more consumer reporting agencies. This is a hard inquiry and may affect your credit.
Consumer reporting agencies are companies that collect credit information and provide credit reports.
Should I roll my closing costs into the loan?
Financing closing costs can reduce what you pay upfront, but increases the balance and the interest paid over time. It does not necessarily eliminate all cash due at closing. Compare the costs paid upfront with the costs financed into the loan.
Is there a rule of thumb for when to refinance?
If the goal is a lower monthly payment, break-even compares the costs of getting the loan, excluding prepaids, with monthly savings and how long you expect to keep it. For other goals, such as a shorter term, cash out or dropping mortgage insurance, this principal-and-interest calculation does not capture every benefit or cost. Whether those trade-offs fit your plans is your judgment. The math helps inform the decision.
How do I find my actual numbers?
Your Loan Estimate provides estimated loan costs and the new principal-and-interest payment; your current mortgage statement provides the current payment. You can use those figures in the calculation above.
