JB PARCELRefinance Break-Even Calculator
A lower rate is not automatically a win. This shows the new payment, the monthly savings, the month you recover the closing costs, and whether resetting the clock costs more than it saves.
How this calculator works
The break-even is closing costs divided by monthly savings. Spend $5,200 to save $260 a month and you are whole in twenty months. Everything after that is profit, and everything before it is a loss if you sell.
The trap is term reset. Most people refinance a loan they have already been paying for a few years back into a fresh thirty. That drops the payment partly because of the better rate and partly because they just added years of interest. The lifetime interest difference output shows you which effect is doing the work. If it is negative, the refinance lowers your payment and raises your total cost, which can still be the right call for cash flow, but you should know you are making that trade.
Rolling costs into the loan changes the math in a subtle way. There is no check to write, so the break-even feels instant, but you financed the costs at the new rate for thirty years. The calculator still charges you the costs in the break-even so you get an honest number.
Dropping PMI is often the biggest single line and the one people forget. If appreciation or principal paydown put you under 80 percent loan-to-value, that monthly premium disappears and it counts as savings just like the rate does.
Worked example: a rate drop on a Memphis rental
$248,000 balance at 7.5 percent with 27 years left. New offer: 6.25 percent on a fresh 30-year, $5,200 in costs rolled into the loan.
| Current payment | $1,787.42 |
|---|---|
| New payment (on $253,200) | $1,559.00 |
| Monthly savings | $228.42 |
| Break-even | 23 months |
| Lifetime interest difference | $23,086 saved |
Just under two years to break even, and the lifetime number still comes out ahead even after adding three years back to the term. If you were planning to sell in eighteen months, you would skip it.
Questions investors ask
What is a good break-even period for a refinance?
Under two years is comfortable for almost anyone. Two to four years is fine if you are confident you will hold the property. Beyond five years the odds that something changes, a sale, a 1031, another rate move, get high enough that the savings are theoretical.
Does a lower rate always save money?
No. If you reset a loan you have been paying for six years back to a full thirty, you can lower the payment and still pay more total interest. Check the lifetime interest difference on this page. Lower payment for better cash flow is a legitimate goal, but call it what it is instead of calling it savings.
Should I roll the closing costs into the loan?
If you plan to hold a long time, paying cash is cheaper because you are not financing the costs at the new rate for thirty years. If cash is your constraint, roll them. The break-even shown here charges the costs either way, so the decision is about liquidity rather than about the math looking better.
Is a cash-out refinance treated the same?
Not quite. Cash-out raises your balance, raises your payment, and usually prices a quarter to a half point above a rate-and-term refinance. Enter the cash-out amount and the calculator handles the payment, but understand that the break-even measures the rate change only. Whether pulling the equity is worth it depends on what you do with it, which is a job for the IRR calculator.
What costs are there on a Tennessee refinance?
Origination, appraisal, title work, and recording, plus Tennessee's indebtedness tax on the new note. That tax is $0.115 per $100 of indebtedness above the first $2,000 under state law, so a $253,000 refinance adds about $289. The Tennessee closing cost calculator itemizes the rest.
