Should I refinance right now? How to actually run the math

Ask the wrong question and you get the wrong answer. The wrong question is: is the rate lower than what I have? That question feels urgent every time rates move, but it does not decide whether refinancing is good for you.

The right question is this: does this loan earn back what it costs me, before I am likely to leave it? A lower rate that costs real money to get, and that never pays for itself before you sell or refinance again, is not a good deal. It just does not feel like a bad one on the day you sign.

We get paid when a loan closes, not when we tell you to wait. Every time we say wait, we are turning down a fee. We say it anyway, because a client who refinances into a loan that never earns back its cost is a client who stops trusting the next quote we send. Here is how to run the actual math, the way we run it ourselves, so you can check our answer instead of taking our word for it.

Break-even is measured on cost, not on the rate

Forget the rate for a second. The number that actually tells you whether to refinance is break-even, and break-even is a cost question, not a rate question.

Start by adding up everything the refinance actually costs you: lender origination fees, title and settlement charges, recording fees, and any discount points you choose to pay to buy the rate down further. That total is your real, out-of-pocket cost of doing this.

Then look at how much your monthly payment drops. Divide the cost by the monthly drop. The result is the number of months you have to keep the new loan before it has paid for itself. Every month after that is money in your pocket that would not exist if you had kept the old loan.

Here is an illustration built entirely from made-up numbers, not a quote, an offer, or available pricing: suppose a refinance costs $4,000 after netting the escrow refund described below, and the new payment is $200 a month lower. Divide $4,000 by $200 and you get 20. Keep the loan past 20 months and the refinance was worth it. Sell or refinance again before then, and you paid for savings you never collected.

The escrow refund, explained honestly

When you refinance, two escrow things happen, and they get blurred together constantly.

First, the old loan's escrow account, the one holding your reserves for property taxes and insurance, gets refunded to you, usually a few weeks after closing once the payoff is processed. Second, you fund a brand new escrow account on the new loan at closing, because every escrowed loan needs a cushion from day one.

That refund is your own money coming back to you. It is not savings the refinance created. It was always yours; it just sat in a reserve account instead of your checking account.

The correct way to treat it, and the way our own math on this site treats it, is to net the refund against the cost of the refinance, because it reduces what you actually have to come out of pocket to close. It does not belong in the savings column, because it is not ongoing and it did not come from a lower rate. Put it on the cost side of the ledger, subtracted, and move on.

The skipped-payment trap

Refinances get sold with a line that sounds like a bonus: you get to skip a payment. It is one of the most common pitches in the industry, and it is not true the way it is usually presented.

You do not skip a payment. You skip a due date. Here is the mechanics of it: interest on your old loan is paid through the day it is paid off, and interest on the new loan starts accruing from the day it closes. There is a short stretch where you are not sending a payment to anyone, but you are not saving that money either.

The money that would have gone toward next month's payment does not disappear and it does not become yours. It goes into the new loan's balance instead, which ends up very slightly larger than it would otherwise be, since the new loan absorbs that gap.

Our math on this site deliberately does not count the skipped payment as savings, and if a lender presents it to you as savings or as extra cash in your pocket, they are padding the pitch. It is a timing effect on your cash flow, not economics. Treat it as neutral and evaluate the refinance on cost and break-even alone.

How long you'll actually keep this loan changes everything

Break-even only means something next to one more number: how long you actually expect to keep the loan. This single input changes the verdict more than the rate spread does.

Someone who is likely to sell the house or refinance again within three years needs a very short break-even to make a refinance worth it. If the break-even lands close to or past that three-year mark, the honest answer is wait or keep what you have, even if the rate improvement looks attractive on paper.

Someone who plans to stay in the home for fifteen years has a lot more room. A break-even of two years, or even three, still leaves twelve-plus years of lower payments after the cost is repaid. The same refinance that is a bad idea for the first person can be an easy yes for the second, at the exact same rate and the exact same cost.

Be honest with yourself about how long you will stay, not optimistic. If you are not sure, use the shorter estimate. A refinance that clears the bar on a conservative timeline is a much safer yes than one that only works if everything goes according to plan.

When the honest answer is wait, or keep what you have

A handful of situations point toward waiting or keeping what you have, clearly enough that we say so before you ever get to a full application.

• The rate spread is too small to overcome the cost. A small improvement is real, but if it barely moves your payment, the cost eats it before it produces anything for you.
• Break-even lands further out than you honestly expect to keep the loan. If you might move or refinance again in three years and break-even is well beyond that, you are betting on a plan that might not hold.
• You only have a short remaining term left. If you have eight or ten years left on your current loan and a refinance resets you to a new thirty-year term, the lower monthly payment can still mean more total interest paid over time, because you are financing the balance over a much longer runway again.
• Your credit or income is about to change. If a credit tier improvement or a new job is weeks away, pricing today is based on the weaker profile, and pricing after the change is not.
• The home's value will not support the loan you want. If a valuation comes in lower than expected, the loan-to-value ratio moves against you and can change the pricing, the mortgage insurance requirement, or whether the loan is possible at all.

What actually moves your number

The rate you see quoted in national news is an average, not your rate. The Freddie Mac Primary Mortgage Market Survey is the standard published source for that national average, and it is a fine general trend indicator. It was never meant to be a quote for your loan.

What actually moves the number in your specific break-even calculation is a short list of things about you and your property, not the news cycle.

• Loan size changes the math because fixed costs like title and recording spread differently over a small balance than a large one.
• Credit moves the pricing you are offered more directly than almost anything else on this list.
• Loan-to-value, meaning how much equity you have relative to the home's value, changes both your pricing and whether mortgage insurance applies.
• Occupancy matters because a primary residence, a second home, and an investment property are priced differently for the same borrower and the same loan amount.
• Property type matters too. A single-family detached home, a condo, and a multi-unit property carry different pricing and different underwriting treatment.
• Whether you pay points changes your cost side of the break-even math directly, and it only makes sense if you are confident you will keep the loan well past the break-even that the points themselves create.

That is why we never publish one number and ask you to apply it to your own situation. Feed your own inputs into a live calculation and you get your own answer, not a stranger's.

How to run your own numbers in five minutes

You do not need a spreadsheet or a phone call to check this yourself first.

1. Open the Should I Refinance tool on the RateVerdict homepage and enter your current balance, your home's estimated value, your current rate, how many years you have left, and your credit range.
2. Press Update. That step prices your specific numbers against live wholesale rate sheets through our licensed broker pricing engines. It is not a placeholder and not a marketing rate.
3. Read the verdict. You will get one of a few honest answers: refinancing is worth it, wait, keep the loan you have, or refinancing would cost you more given your remaining term. The break-even math behind the answer is shown, not hidden.
4. If the verdict says wait or keep, believe it. It costs us a fee to tell you that, and we tell you anyway.
5. If you want a person to check the exact numbers against your actual documents rather than estimates, a licensed loan officer on our team can do that from the same page.

The bottom line

Should you refinance right now? Run your actual numbers and let the math answer, not the headline rate, and not a lender who gets paid whether or not the loan ever earns back its cost for you.
