The Refinance Break-Even Point Explained
The break-even point is the most useful number in any refinance decision. After 17 years and over $1 billion in funded loans across the United States, it is still the single calculation I ask every borrower to run before we talk about rates. It tells you exactly how long it takes for the refinance to pay for itself. Let me show you how it works.
What Is the Break-Even Point?
When you refinance, you pay closing costs. Every month after that, you save money through a lower payment. The break-even point is when your total savings equal the closing costs you paid.
Before the break-even point, you are still "paying off" the cost of the refinance. After the break-even point, the savings are pure benefit.
How to Calculate It
The formula is simple.
Total closing costs divided by monthly savings equals your break-even point in months.
If it takes 18 months to break even and you plan to stay in your home for 10 more years, the refinance makes sense. You would benefit from the savings for over 8 years after breaking even.
If it takes 5 years to break even and you might move in 3 years, the refinance may not pay off.
What Is a Good Break-Even Point?
There is no single right answer, but here are some guidelines.
Under 18 months. This is strong. The refinance pays for itself quickly.
18 to 36 months. This is solid if you plan to stay at least a few more years.
36 to 60 months. This can still work if you are confident you will stay long term.
Over 60 months. Think carefully. A lot can change in five years.
Common Mistakes With Break-Even Calculations
Forgetting to include ALL closing costs. Make sure you account for every fee, not just the lender's charges.
Not considering term changes. If you are extending your loan, your "savings" might actually cost you more in total interest, even if the monthly payment is lower.
Ignoring the time value of money. A dollar saved today is worth more than a dollar saved in 10 years. For most homeowners, this is a minor factor, but it is worth knowing.
