How to calculate your refinance break-even point
A lower mortgage rate or monthly payment can make refinancing sound like an easy decision. But before you move forward, there’s another number worth knowing: your refinance break-even point.
Refinancing comes with costs, and your break-even point tells you how long it could take for your monthly savings to make up for those expenses. The calculation itself is pretty simple. The more important question is what that number means for you. If you expect to keep the new loan beyond your break-even point, refinancing has more time to deliver savings. If you’re planning to move, sell or refinance again before you get there, the upfront cost deserves a closer look.
Below, we’ll show you how to calculate your break-even point step by step, including examples using $350,000, $400,000 and $650,000 refinance amounts, plus what changes when you’re considering a cash-out refinance.
Key takeaways:
- Your refinance break-even point estimates how long it takes your monthly savings to recover the cost of refinancing.
- To calculate it, divide your total refinance closing costs by your estimated monthly savings.
- Lower closing costs or greater monthly savings generally shorten the break-even period.
- A lower monthly payment doesn’t automatically mean refinancing will save you money overall.
- Cash-out refinancing requires a different comparison because you’re borrowing additional money, not simply replacing your current mortgage balance.
What is the break-even point on a refinance?
The break-even point on a refinance is when the savings from your new mortgage catch up with what you spent to refinance.
For example, say refinancing costs you $7,500 and lowers your monthly principal and interest payment by $250. After 30 months of saving $250 per month, you’ve recovered the $7,500 you spent on the refinance.
From that point forward, the accumulated monthly savings begin to exceed those initial costs.
That’s why the break-even point can be more useful than looking at the new interest rate alone. A lower rate may look appealing, but you still need enough time for the savings to offset the cost of getting the new loan.
How do you calculate your refinance break-even point?
You only need two numbers to estimate your break-even point: how much the refinance will cost and how much you expect to save each month.
Use this formula: Total refinance closing costs ÷ monthly savings = months to break even
For example: $7,500 in closing costs ÷ $250 in monthly savings = 30 months
In this example, it would take about two and a half years to reach the break-even point.
For a straightforward rate-and-term refinance, monthly savings generally means the difference between your current principal and interest payment and your estimated new principal and interest payment.
Once you have your answer, compare it with how long you realistically expect to keep the new mortgage. If you expect to sell the home or refinance again before reaching that point, you may not have enough time to recover the cost through monthly payment savings.
What closing costs should you include?
A useful break-even calculation starts with an accurate estimate of what you’ll actually pay to refinance.
Refinance closing costs may include:
- Origination or lender fees
- Appraisal fees
- Title and settlement services
- Recording fees
- Discount points, if you pay them to lower your rate
- Other applicable loan costs
If you decide to roll closing costs into your new mortgage instead of paying them upfront, remember that those costs don’t disappear. Financing them increases the amount you borrow and may affect both your monthly payment and the amount of interest you pay over time.
Refinance break-even examples
The formula is simple, but seeing the numbers can make it easier to understand how closing costs and monthly savings work together.
The examples below are hypothetical and provided for educational purposes. They don’t represent current interest rates or loan offers, and actual rates, payments and costs will vary by borrower and loan.
Example 1: $350,000 refinance
Say you’re refinancing a $350,000 mortgage. Using a 2.5% closing-cost estimate, your refinance costs would be approximately $8,750.
Now assume your new mortgage lowers your monthly principal and interest payment by $275.
| Calculation detail | Amount |
|---|---|
| Closing costs | $8,750 |
| Monthly savings | $275 |
| Break-even calculation | $8,750 ÷ $275 |
| Break-even point | About 32 months |
In this example, it would take about two years and eight months for your accumulated monthly savings to equal the estimated closing costs.
If you plan to keep the new mortgage well beyond that point, you can then look at how much additional savings the refinance could provide over the time you expect to keep the loan.
Example 2: $400,000 refinance
Now let’s look at a $400,000 refinance.
Using the same 2.5% assumption, estimated closing costs would be $10,000. If the refinance lowers your monthly principal and interest payment by $400, the break-even calculation would be as follows:
| Calculation detail | Amount |
|---|---|
| Closing costs | $10,000 |
| Monthly savings | $400 |
| Break-even calculation | $10,000 ÷ $400 |
| Break-even point | 25 months |
Here, it would take just over two years for the monthly savings to make up for the estimated cost of refinancing.
This is a good example of why the size of your mortgage alone doesn’t determine your break-even point. What matters is the relationship between what you spend to refinance and how much you save each month.
Example 3: $650,000 refinance
For a $650,000 refinance, estimated closing costs at 2.5% would be $16,250.
Say the new loan reduces your monthly principal and interest payment by $625.
| Calculation detail | Amount |
|---|---|
| Closing costs | $16,250 |
| Monthly savings | $625 |
| Break-even calculation | $16,250 ÷ $625 |
| Break-even point | 26 months |
Even though the estimated closing costs are considerably higher than in the first example, the greater monthly savings keep the break-even period at a little over two years.
This is why it helps to run the calculation using your own numbers instead of relying on a general rule for how long a refinance should take to pay off.
How does a cash-out refinance affect your break-even point?
A cash-out refinance changes the calculation because you’re doing more than replacing your existing mortgage. You’re taking out a larger loan and receiving a portion of your home equity as cash.
For example, say you currently owe $350,000 but refinance into a $400,000 mortgage. Part of the difference, after paying applicable costs and your existing mortgage balance, may be available to you as cash.
If your new monthly payment increases, the traditional break-even formula doesn’t tell the whole story because there may not be monthly payment savings to measure.
Instead, consider the broader cost of accessing the cash, including:
- Your new monthly mortgage payment
- The amount of cash you’ll receive
- Refinance closing costs
- Your new interest rate
- Your new loan term
- How long you expect to keep the mortgage
If you’re using cash-out proceeds to consolidate higher-interest debt, you’ll also want to compare the cost and repayment period of your new mortgage with the debts you’re paying off.
For example, lowering your total monthly debt payments could improve your monthly cash flow, but moving shorter-term debt into a longer mortgage may increase how long you’re paying it back. Looking beyond the monthly payment can give you a more complete picture of the tradeoff.
What is a good break-even point for refinancing?
There isn’t one break-even point that works for every homeowner.
A break-even period of two years could make sense for someone who expects to stay in the home for another decade. That same timeline may be less appealing to someone planning to move next year.
Instead of focusing on a universal number, ask yourself: How long do I realistically expect to keep this mortgage?
Compare that timeline with your estimated break-even point. The more time you expect to keep the loan after breaking even, the more opportunity there may be for your monthly savings to add up.
Your reason for refinancing matters, too. Some homeowners refinance to lower their rate or payment, while others want to shorten their loan term, switch from an adjustable-rate to a fixed-rate mortgage or access home equity. In those situations, the break-even point is still useful, but it may be only one part of the decision.
What can change your refinance break-even point?
Your break-even period isn’t based on your interest rate alone. Several parts of your refinance can shorten or extend the timeline.
Closing costs
The more you spend to refinance, the more savings you’ll need to recover those costs. Comparing Loan Estimates can help you understand how different loan options affect your upfront expenses.
Monthly savings
Greater monthly savings generally lead to a shorter break-even period. A small payment reduction may still help your monthly budget, but it can take longer to recover the cost of refinancing.
Loan term
Starting a new 30-year mortgage can lower your monthly payment partly because you’re spreading repayment over a longer period.
If you’ve already been paying your current mortgage for several years, compare the remaining term of your existing loan with the term of the new one. A lower monthly payment doesn’t necessarily mean you’ll pay less over the full life of the loan.
Financed closing costs
Rolling closing costs into your new mortgage can reduce the amount of cash you need at closing, but it also increases your loan balance.
That can affect your monthly payment and the amount of interest you pay, so include financed costs when you’re comparing the overall value of your refinance.
How can you lower your refinance break-even point?
If your break-even timeline feels longer than you expected, there may be different loan scenarios worth comparing.
For example, you could look at a refinance with fewer upfront costs, compare the cost of paying discount points with the additional monthly savings they provide or explore different loan terms.
The option with the lowest rate isn’t automatically the one with the shortest break-even period. A slightly higher rate paired with lower upfront costs could reach the break-even point sooner in some situations.
Use a refinance break-even calculator to run your own numbers
Examples are helpful, but the numbers that matter most are yours.
Our refinance calculator lets you enter information about your current mortgage and proposed refinance, including your current interest rate, principal and interest payment, outstanding balance, new loan amount, preferred term, expected interest rate and closing costs.
The calculator can then estimate your new principal and interest payment, payment difference and break-even point.
Try running a few scenarios instead of stopping at the first result. Comparing different rates, loan terms and closing costs can give you a better idea of how each option could affect your monthly payment and how long it may take to recover the cost of refinancing.
Look beyond the break-even point before you refinance
Your refinance break-even point gives you a practical way to compare the cost of refinancing with the savings you could receive over time. But it’s still only one part of the decision.
Consider how long you expect to keep the mortgage, what you’ll pay in closing costs, how the new loan term compares with your existing one and what you ultimately want the refinance to accomplish.
