## The short answer

Refinance when the net cost (closing costs after lender credits, leaving out escrow) divided by your true monthly savings (principal, interest and mortgage insurance on both loans) pays back well inside the time you'll keep the new loan. My rule of thumb is 24 months or less. Example: $5,000 of net cost against $343 a month of savings breaks even in about 15 months. Then check that a fresh 30-year term isn't quietly handing the savings back.

Your rate is higher than what you keep hearing about, and your servicer keeps calling. The real question is not whether rates moved. It is whether the drop pays back what the refinance costs before you sell or refinance again, and whether a fresh 30-year term hands the savings right back. Knowing when to refinance your mortgage comes down to the math below, including the parts most calculators skip.

## When does it make sense to refinance your mortgage?

When the true savings pay back the net cost well before you are done with the loan. People refinance for four reasons: a lower rate, dropping mortgage insurance, changing the term, or pulling cash out. Cash-out has its own math. The other three all get the same first test from me, break-even, and I run it even when a homeowner tells me restarting a 30-year does not bother them. Just because you can doesn't mean you should.

## How to calculate your refinance break-even

Break-even is the net cost divided by the true monthly savings. The answer is in months, and it has to fit comfortably inside the time you will keep the loan. Both numbers have a trap in them.

- **Net cost** is the closing costs minus any lender credit: lender charges, appraisal, title, settlement and recording. Leave out the new escrow deposit and the prepaid interest. They are not costs of the refinance, and the next section shows why.
- **True monthly savings** compares the cost of borrowing on both sides: principal, interest and mortgage insurance. If your current loan carries PMI and the new one will not, that difference is savings. Check your statement, because mortgage insurance is sometimes folded into the escrow line where people miss it. On an FHA loan, add the annual MIP to the rate: a 6.5% FHA loan with 0.55% MIP costs like 7.05%.

**Worked example: True monthly savings on a $300,000 refinance**
- Current principal and interest (7.5%, 28 years left): $2,139
- plus Current PMI: $100
- minus New principal and interest (6.5%, 30 years): $1,896
- equals: True monthly savings: $343
Note: The home is now worth about $390,000, so the new loan is under 80% of value and the PMI goes away.
_Hypothetical example, rounded. Taxes and insurance are left out because they do not change._


**Worked example: Net cost and break-even**
- Closing costs (lender, appraisal, title, settlement, recording): $7,500
- minus Lender credit: $2,500
- equals: Net cost: $5,000
Note: $5,000 divided by $343 is about 15 months to break even.


My rule of thumb is 24 months or less. The reason is behavior, not math: most people refinance again or sell sooner than they expect. If you might sell inside about two years, stacked costs usually mean you should not refinance at all.

Notice what the PMI does. Leave it out and the same refinance saves $242 a month, a 21-month break-even. Small savings stack. The [refinance break-even calculator](https://nobullshitloans.com/tools/refinance-break-even/) does this arithmetic for you; give it the net cost, not your cash to close.

## Why cash to close is the wrong number

Cash to close mixes the cost of the refinance with money that is still yours.

**Worked example: Cash to close on the same refinance**
- Net cost of the refinance: $5,000
- plus New escrow account deposit: $3,600
- plus Prepaid interest to the end of the month: $900
- equals: Cash to close: $9,500
Note: About $3,000 from your old escrow account comes back as a refund after the old loan is paid off.
_Hypothetical example, rounded._


Divide $9,500 by $343 and you get 28 months, a fail. The refinance actually pays back in 15. Two things inflate cash to close:

- **The escrow deposit.** Your new loan needs its own escrow account for taxes and insurance. Your old servicer refunds the old escrow balance after payoff, so funding the new one is a wash. It is your tax and insurance money moving from one account to another.
- **Prepaid interest.** It covers the days between closing and the end of the month on the new loan. You owe interest for those days either way, and now at the lower rate. It is also why your first new payment comes later.

## Is it worth refinancing for 1 percent?

It depends on your balance more than the rate. The same 1-point drop that pays back fast on a big loan can take years on a small one, because closing costs do not shrink with the loan.

| Balance | 1 point lower (7.5% to 6.5%) | Half a point lower (7.0% to 6.5%) |
|---|---|---|
| $150,000 | $121 a month, 41 months | $71 a month, 70 months |
| $300,000 | $242 a month, 21 months | $143 a month, 35 months |
| $450,000 | $364 a month, 14 months | $214 a month, 23 months |

Principal and interest only, on a current loan with 28 years left moving to a new 30-year, with $5,000 of net cost on every row. Example rates, rounded.


**Chart: Months to break even, by loan balance.** Closing costs don't shrink with the loan, so the same drop pays back faster on a bigger balance. My test is 24 months or less.

|  | 1 point lower | Half a point lower |
|---|---|---|
| $150,000 | 41 months | 70 months |
| $300,000 | 21 months | 35 months |
| $450,000 | 14 months | 23 months |

_$5,000 of net cost on every balance. Principal and interest only, on a current loan with 28 years left at 7.5% or 7.0%, moving to a new 30-year at an example rate of 6.5%. Hypothetical, not a quote._


On a $300,000 loan, a full point passes my 24-month test and a half point does not, unless mortgage insurance is coming off too. My conversation with a past client starts when the market sits around half a point under their rate, but the break-even makes the call, not the rate gap.

## The term-reset trap

A new 30-year loan restarts the clock. Two years into your current loan, a refinance adds two years of payments. Five years in, it adds five. The lower payment can hide a higher total cost, and the further into your loan you are, the more the reset costs.

| Your loan today ($300,000 left) | New 30-year at 6.5%: payment | New 30-year: lifetime interest, with $5,000 cost | Same refinance, old payment kept up |
|---|---|---|---|
| 7.5%, 28 years left | $242 lower | $30,900 less | Paid off in 22.1 years, $148,900 less |
| 7.5%, 25 years left | $321 lower | $22,500 more | Paid off in 20.4 years, $118,200 less |
| 7.5%, 20 years left | $521 lower | $107,600 more | Paid off in 17.2 years, $75,800 less |
| 7.0%, 28 years left | $143 lower | $2,600 more | Paid off in 24.7 years, $78,200 less |

Interest is compared with finishing the loan you have, principal and interest only, each loan run to the end. Example rates, rounded.


**Chart: What a fresh 30-year costs vs finishing your 7.5% loan.** With 28 years left, the reset still saves $30,900. With 25 left it costs $22,500 more, and with 20 left, $107,600 more.

| Years left on your loan, $300,000 owed at 7.5% | Lifetime interest vs your current loan |
|---|---|
| 28 years | −$30,900 |
| 25 years | $22,500 |
| 20 years | $107,600 |

_Above zero costs you more. $300,000 owed at 7.5%, refinanced into a new 30-year at an example rate of 6.5% on the new required payment, with the $5,000 cost counted in. Interest is compared with finishing the loan you have, principal and interest only, each loan run to the end. Hypothetical, not a quote._


Look at the second row. The rate drops a full point, the payment drops $321, and you still pay $22,500 more over the life of the loan. Send the old payment instead and the same refinance saves $118,200 and finishes four and a half years early.

There are two fixes. Keep paying the old payment, or choose a shorter term if the old payment was comfortable; shorter terms often price a little better too. In the $300,000 example, a 20-year at 6.5% runs about $2,237 a month, almost exactly the old payment with PMI. I usually prefer the 30-year with the old payment kept up. Same result if you stick to it, and in a tight month you can fall back to the required payment.

## Keep paying the old payment, and your freedom point

The simplest way to beat the trap is to act like the refinance never lowered your payment.

**Worked example: Keep paying the old payment**
- Old payment, principal and interest plus PMI: $2,239
- minus New required payment: $1,896
- equals: Extra principal every month: $343
Note: Paid this way, the new loan is gone in 20 years instead of the 28 left on the old one, with about $182,000 less interest.
_Hypothetical example from above, rounded. Keeping up only the old principal and interest, it is 22 years, as in the table._


I also show clients what I call the freedom point: the month a savings account, fed with the monthly savings, holds enough to pay off what is left on the loan. Same $343, different bucket. The math has a clean rule. If that money earns exactly your mortgage rate, the freedom point lands on the same month prepaying would have paid the loan off, 20 years in this example. If it earns nothing, the stack catches the balance around year 25. If it earns more than your mortgage rate, the freedom point comes first.

**My take**
Prepaying earns exactly your mortgage rate with no risk, but the money is locked in the house. A savings stack stays reachable for a job loss or a new roof, and only comes out ahead if it earns more than your rate, which nobody can promise. Either way, a refinance is just a decision about where those savings go each month. Make it on purpose.


## What a "no closing cost" refinance really costs

There is no such thing as a free lunch. The costs still get paid: by a higher rate that earns a lender credit, or by rolling them into the balance.

With a lender credit, the break-even runs in reverse. Divide the credit by how much more the higher rate costs each month. That tells you how long until the higher payment has eaten the credit.

**Worked example: Reverse break-even on a lender credit**
- Payment at 6.875%, with a credit covering the $5,000: $1,971
- minus Payment at 6.5%, paying the $5,000 yourself: $1,896
- equals: Extra cost of the credit each month: $75
Note: $5,000 divided by $75 is about 67 months. Refinance again or sell before then and the credit wins.
_Hypothetical example, $300,000 loan, example rates, rounded._


Sixty-seven months is more than five years. If the plan is to refinance again when the market allows, the credit usually wins. If this is the loan you will keep for a decade, pay the costs and take the lower rate. [Points versus lender credits](https://nobullshitloans.com/buy/points-and-buydowns/) walks through the rate sheet side of the same trade.

Rolling costs into the balance is the third way. Each $1,000 added costs about $6 a month at 6.5%.

**Watch out**
If dropping PMI is part of your savings, make sure the new loan, with costs rolled in, still lands at or under 80% of the appraised value. Roll in too much and the PMI you were trying to get rid of stays. [How PMI and FHA MIP come off](https://nobullshitloans.com/buy/mortgage-insurance/) covers the other ways out.


## Refinance closing costs in Virginia

When I plan a refinance, I budget 2.5% to 3% of the loan for closing costs before any lender credit. That covers lender charges and any points, the appraisal unless it is waived, the credit report, the title search and lender's title policy, the settlement fee, recording fees and Virginia's recordation tax.

Virginia gives refinances a break on that tax. When the new loan pays off a debt that was already taxed when it was recorded, the state rate drops to 18 cents per $100, plus a local tax of one-third of that where the locality levies it, which most do. That is about 24 cents per $100 in all, or about $720 on a $300,000 refinance, versus about $1,000 for a new purchase loan of the same size. The line-by-line picture is on the [Virginia closing costs](https://nobullshitloans.com/virginia/closing-costs/) page.

## Stop the bleeding now, refinance again later

If you are at 7.5% or 8% and a refinance gets you a real rate drop with few or no points, I call that a stop-the-bleeding refinance. Take the savings now. Skip the points, because you would be paying to lower the rate on a loan you may replace. On government loans the next step can be a streamline: an [FHA streamline](https://nobullshitloans.com/refinance/fha-streamline/) or a [VA IRRRL](https://nobullshitloans.com/refinance/va-irrrl/), each after six payments and 210 days.

That is the idea behind date the rate, marry the house. You bought the house you wanted at the rate the market gave you, and the plan is to refinance when the math works. That is positioning, not a promise. Rates may not cooperate, so budget for the payment you have, not the one you hope to get.

Waiting is a bet too. I have watched a homeowner hold out for a better quarter and lose about 1.5 points of pricing, roughly $4,500 on a $300,000 loan. I don't have a crystal ball. What you can do is get positioned: the application in and the documents uploaded, so when pricing moves your way the rate can be locked that day.

## Payoff, per diem and the "skip a payment" myth

Your payoff is not the balance on your statement. Mortgage interest is paid a month behind, so the payoff adds every day of interest since your last payment. That daily charge is called per diem interest: the balance times the rate, divided by 365 or 360 depending on the servicer. At $300,000 and 7.5%, it is about $62 a day either way ($61.64 or $62.50). Ask which one yours uses; over a month it moves the payoff about $26.

I have clients order the payoff themselves on the servicer's website: refinancing as the reason, emailed, with a good-through date a few days past the target closing. Let your last payment post, then request it. A stale payoff is one of the quiet reasons refinances miss their closing date, and a missed date can mean paying to extend a rate lock. On a refinance of the home you live in, federal law usually gives you until midnight of the third business day after signing to cancel, so the loan funds after that. Your lock has to last through funding day, not signing day.

Now the myth. People leave a refinance closing convinced they got a free month. Say your last payment was November 1. You sign on November 16, the right to cancel runs out, and the loan funds on November 20. No December payment goes to anyone, and the new loan's first payment is due January 1. Nothing was forgiven.

**Worked example: Where the "skipped" December payment went**
- Old loan: 19 days of November interest, inside the payoff: $1,171
- plus New loan: 11 days of November interest, paid at closing: $588
- equals: November's interest, settled at closing: $1,759
Note: Your December 1 payment would have covered November's interest. It got paid at closing instead, and your January 1 payment covers December.
_Hypothetical example: $300,000 balance, 7.5% old rate, 6.5% new, 365-day interest, rounded._


It is timing, not forgiveness. Add the old escrow refund that arrives after payoff, and a refinance can feel like a windfall. It is your own money arriving on a different schedule. If a payment comes due before your loan funds, make it; never gamble a late payment on a closing date. If the old servicer ends up with more than the payoff, the extra comes back to you.

## How to compare refinance offers

Compare locked Loan Estimates to locked Loan Estimates. A text message or a fee sheet is not an offer.

1. Get every offer as a Loan Estimate, locked, on the same day. Pricing moves daily, so quotes from different days are not comparable.
2. Make the loan amounts match. A quote built on a stale balance will look cheaper than one built on your real payoff.
3. Read Section A for origination and points, then find the lender credit. A lower rate that costs two points is a different loan.
4. Add up the closing costs and subtract the credit to get each net cost. Leave out prepaids and the escrow deposit, but check that each lender estimated them the same way.
5. Compare principal, interest and mortgage insurance on each loan, then run the break-even on each one.


**Watch out**
If one offer's cash to close is far lower but its costs are not, check whether it is counting your old escrow refund as a credit. That refund comes back to you either way, so it does not make that offer any cheaper.


## When to wait

A refinance is the wrong move when:

- The market is not far enough below your rate for the break-even to fit how long you will keep the loan.
- You might sell or move before the break-even month.
- You are well into your loan and the rate drop is small, unless you take a shorter term or keep paying the old payment.
- You have a low rate and need cash. A second loan leaves that rate alone; [HELOC vs cash-out refinance](https://nobullshitloans.com/refinance/heloc-vs-cash-out/) runs the comparison.
- PMI is the main reason. Your servicer may drop it on your home's current value without a refinance: on Fannie Mae loans, generally once you owe 75% or less of that value after two years of payments, or 80% after five, with a clean payment record and a new valuation. This works for private mortgage insurance only, not FHA MIP.
- Your payment went up because taxes or insurance did. Fixed means principal and interest are fixed. Escrow is not, and a refinance does not change it.
- The real problem is the payment itself, or you are already behind. A refinance by itself won't fix that. Start with [what to do when you're behind on your mortgage](https://nobullshitloans.com/refinance/behind-on-your-mortgage/).

Every refinance I recommend has to pass two checks: the break-even fits, and the term does not hand the savings back. If either one fails, the honest answer is to wait, keep your documents current, and run it again when the market moves.

## Frequently asked questions

### How soon can I refinance after buying a house?

An FHA streamline or a VA IRRRL requires six payments and 210 days, and each program counts the 210 days from a different date, so plan on roughly seven to nine months after you close. For other rate-and-term refinances, my general plan is six on-time payments, and a cash-out has its own waiting rules, usually longer. Extra payments do not speed up the clock, so park that cash instead of prepaying.

### Do I save on closing costs if I refinance with the same lender?

Not on Virginia's recordation tax. Since July 1, 2012, the reduced refinance rate applies whether you stay with your lender or move, and there is no same-lender exemption. Lender fees are set by each lender, so compare locked Loan Estimates instead of assuming loyalty pays.

### My mortgage company called with a refinance offer. Should I take it?

Ask for it as a Loan Estimate and compare it with at least one other locked Loan Estimate from the same day. Look at Section A first, because a low teaser rate usually comes from paying points. Mail that looks like it came from your lender often did not, since mortgages are public record.

### Should I use a lump sum to pay the loan down, buy the rate down, or keep it?

Run each one through break-even. At an example rate of 6.5%, each $1,000 of principal lowers the payment about $6, so paying $37,000 down to reach 80% saves about $234 plus roughly $100 of PMI, and takes about nine years to earn back. Points get my 24-month test, and cash you keep is the only one of the three you can still reach in an emergency.

### Why did my loan amount go up between the estimate and closing?

The official payoff is higher than early estimates because it adds the interest owed since your last payment, while those estimates often use the balance from your credit report or last statement. Judge the deal by the net cost and the monthly savings, not by the loan amount.
