## Quick answer

Your simple break-even point is total closing costs divided by the monthly saving in principal and interest. With costs of 3%–6% of the loan, a one-point rate cut on a $150,000 balance saves about $98 a month and pays back $4,500 in **3 years 10 months**. A fuller test also counts the balance you still owe, which moves the answer earlier when you keep the same term and later when you stretch it or roll costs into the loan.

## The simple formula

**Break-even months = total refinance costs ÷ monthly saving.**

Both halves need care:

- **Costs** are what the refinance itself costs you: the loan costs on your Loan Estimate (origination charges including any points, plus the services in sections B and C) and the taxes and government fees in section E. Each point is 1% of the loan. Subtract any lender credit. Leave out prepaid interest, homeowners insurance and the new escrow deposit — you would pay those anyway, and the old escrow balance is usually refunded.
- **Saving** is the drop in principal and interest. Taxes and insurance don’t change when you refinance, so ignore them — but if the new loan ends PMI or FHA mortgage insurance, add that too.

If your payment goes up — because you chose a shorter term — the simple formula has nothing to divide by, and only the fuller test below can tell you when you come out ahead.

## Why the simple number can mislead

The simple formula only looks at the payment. It ignores how fast each loan is paid down, which is where two common traps hide:

- **A longer term.** Moving 25 remaining years into a new 30-year loan lowers the payment partly by spreading the debt over more years. The saving looks bigger than it is.
- **Rolled-in costs.** Adding costs to the loan means no cash today, but a bigger balance and a smaller saving. It doesn’t make the break-even disappear.

The **full break-even** compares where you stand on each path at every month: payments made plus balance still owed, plus any costs paid in cash. It is the method our [break-even calculator](https://mortgage-math-us.com/tools/refinance-break-even-calculator/) charts year by year. It can come out *earlier* than the simple answer too — when the new term is no longer than the old one, a lower rate pays the balance down faster on top of cutting the payment.

## Example 1: a smaller balance, same term

> **Worked example: $150,000 balance at 8.24% with 25 years left, $4,500 of costs paid in cash**
>
> | New loan at 7.24% | Monthly saving | Simple break-even | Full break-even | Net position after 5 years |
> |---|---:|---:|---:|---:|
> | 25-year (same term) | $98 | 3 years 10 months | 3 years | +$3,032 |
> | 30-year (term stretched) | $159 | 2 years 5 months | 3 years 3 months | +$2,298 |
> 
> The current rate is an example one point above this week’s Freddie Mac 30-year average. Costs use the low end of Freddie Mac’s 3%–6% range. Net position counts payments, the balance owed and the costs.

Keeping the same term, the full break-even arrives before the simple one, because the lower rate also shrinks the balance faster. Stretch to 30 years and the payment saving rises to $159, so the simple number looks better — but the full break-even comes later and you are less far ahead after five years, because much of that “saving” is debt pushed into the future. On a small balance the dollars are small either way: some costs, such as the appraisal and recording fees, don’t shrink with the loan, so they weigh more on a modest balance.

## Example 2: paying costs in cash vs rolling them in

> **Worked example: $220,000 balance at 8.24% with 26 years left, new 30-year loan at 7.24%, $6,600 of costs**
>
> | | Costs paid in cash | Costs rolled into the loan |
> |---|---:|---:|
> | New loan amount | $220,000 | $226,600 |
> | Monthly saving | $214 | $169 |
> | Simple break-even | 2 years 7 months | 3 years 4 months |
> | Full break-even | 3 years 2 months | 4 years 2 months |
> | Net position after 2 years | −$2,305 | −$3,251 |
> | Net position after 5 years | +$3,647 | +$1,320 |
> | Net position after 10 years | +$11,674 | +$7,181 |

Rolling the costs in doesn’t make the refinance free: it trims the saving by $45 a month and pushes the full break-even back by 1 year. Either way, selling after two years would leave you behind. A third option — taking a higher rate in exchange for a lender credit — is covered in our [no-closing-cost refinance](https://mortgage-math-us.com/refinancing/no-closing-cost-refinance/) guide.

## How long will you keep the loan?

A break-even point only means something next to the number of years you expect to keep this mortgage — and that is often shorter than the years you expect to live in the house. The loan ends early if you:

- **Sell or move** for work, family or a bigger home.
- **Refinance again** because rates fall further, or to take cash out later.
- **Pay it off early** with extra payments or a windfall.

The CFPB suggests testing the shortest, longest and most likely time you might keep a loan when weighing points and credits; the same habit works here. If the full break-even falls well inside your shortest likely stay, the refinance is low-risk. If it lands near or beyond it, the savings are a bet on staying put. For reference, the law requires a VA streamline refinance to recoup its costs within 36 months — a useful yardstick for any refinance.

## Frequently asked questions

### How do you calculate the break-even point on a refinance?

Divide the total refinance costs by the monthly saving in principal and interest. $4,500 of costs and a $98 saving pay back in 3 years 10 months. For a fuller answer, compare payments plus balance owed on each loan month by month.

### What is a good break-even period for a refinance?

There is no official standard. Compare it with the shortest time you might keep the loan. For VA streamline refinances, the law sets a limit of 36 months, which is a sensible yardstick for any refinance.

### Should I include escrow and prepaid interest in refinance costs?

No. Prepaid interest, homeowners insurance and the new escrow deposit are costs you would have anyway, and the old escrow balance is usually refunded. Count the loan costs, points and government recording fees, minus any lender credit.

### If I roll closing costs into the loan, is there still a break-even point?

Yes. You don’t pay cash, but the bigger balance shrinks the monthly saving and adds interest. In the example above, rolling $6,600 into the loan pushed the full break-even from 3 years 2 months to 4 years 2 months.

### Why can the full break-even come before the simple one?

When the new term is no longer than the years you have left, a lower rate means more of each payment goes to principal. You build equity faster on top of the payment saving, so you get ahead sooner.

### Do discount points count toward break-even?

Yes. Points are a cost of the refinance — each is 1% of the loan — and they need their own break-even: the extra cost divided by the extra monthly saving they buy.
