Refinance Break-Even Point Calculator
The break-even point is the closing costs divided by the monthly saving. Refinancing $300,000 from 7% to 6% on the same 25 years lowers the payment by $187.43 a month, so $9,000 of closing costs are paid back in 49 months (4 years 1 month).
Enter your own balance, rates, term and closing costs below, then see how the rate drop and the cost move the answer.
Refinance break-even calculator
Payment now $2,120.34, after the refinance $1,932.90.
You save $187.43 a month and break even after 49 months (4 years 1 month).
Interest over the full terms: $336,101 now against $279,871 after, plus $9,000 of closing costs.
How much the rate drop matters
Each row is $300,000 at 7% with 25 years left, refinanced for the same 25 years with $9,000 of closing costs.
| New rate | New payment | Saved a month | Break-even |
|---|---|---|---|
| 6.50% | $2,025.62 | $94.72 | 96 months |
| 6.25% | $1,979.01 | $141.33 | 64 months |
| 6.00% | $1,932.90 | $187.43 | 49 months |
| 5.50% | $1,842.26 | $278.08 | 33 months |
How much the closing costs matter
Same loan, refinanced to 6%. The closing costs set how long the saving takes to cover them.
| Closing costs | Share of the loan | Break-even |
|---|---|---|
| $6,000 | 2.0% | 33 months |
| $9,000 | 3.0% | 49 months |
| $12,000 | 4.0% | 65 months |
| $15,000 | 5.0% | 81 months |
PNC says refinance closing costs are often estimated at 2% to 5% of the loan amount.
The new term can undo the saving
Refinancing to 6% with a new 30-year term instead of 25 years cuts the payment to $1,798.65 but adds interest: $347,515 over the new term against $279,871 on 25 years. Compare the full cost, not only the payment. For a refinance against a recast on the same loan, use the recast vs refinance calculator.
Frequently asked questions
How do I calculate the break-even point on a refinance?
Divide the closing costs by the monthly saving. On $300,000 at 7% refinanced to 6% for $9,000, the payment falls $187.43 a month, so $9,000 / $187.43 is 49 months.
What is a good break-even point?
A refinance pays off only if you keep the loan past the break-even month. Compare the number with how long you expect to stay in the home: if you may sell sooner, the closing costs are not paid back.
Why does a longer new term change the answer?
A new 30-year term on the example drops the payment to $1,798.65, a saving of $321.69 a month and a break-even of 28 months. But the interest over the full terms rises from $279,871 to $347,515, so the lower payment costs more overall.
Do I add the closing costs to the loan?
If you roll them into the new balance, the payment rises a little and the break-even moves out. Enter the balance with the costs included and set the closing costs to zero to see the payment, or keep them separate to see the break-even.
Is a recast an alternative?
A recast keeps your rate and end date and costs a small fee, so it has no rate drop to break even on. See the recast vs refinance comparison for the two side by side.
