Cost To Refinance Mortgage Calculator
Refinancing a mortgage almost always costs 2 to 5% of the loan amount in closing costs, so the only question that matters is whether the monthly savings earn those costs back before you sell or refinance again. A refinance that looks cheap in a lender quote can still lose money if you move in year three.
This calculator totals the costs two ways, as a quick percentage of the loan or as an itemized fee list with prepaid interest computed from your actual rate, then compares paying the fees upfront with rolling them into the loan, and finishes with the break-even month and a plain yes-or-no verdict for the stay you plan.
| Fee | Amount |
|---|
Estimates only. Your Loan Estimate from the lender is the authoritative fee list, and prepaid escrow deposits for taxes and insurance vary by state and closing date.
Quick Answer
Key takeaways
- Closing costs are only half the decision. The break-even month, total costs divided by monthly savings, is the other half.
- Rolling fees into the loan more than doubles their cost on a 30-year term: $9,000 of fees becomes $19,843.99 with interest.
- Itemized mode exposes the lines a quote can hide, and prepaid interest is computed from your rate and closing days, not guessed.
- Prepaids and escrow deposits are cash due at closing, but they are mostly money you would pay anyway, which is why lenders counting them differently produce very different totals.

How to use the refinance cost calculator
Start in quick mode if you only have a ballpark quote: enter the new loan amount and the percentage a lender quoted, or leave it at 3%, the midpoint of the typical 2 to 5% range. Switch to itemized mode when you have a Loan Estimate in hand, because that is when the interesting questions appear: which lender is charging more for origination, whether the points are worth buying, and how much of the total is prepaids rather than fees. The Consumer Financial Protection Bureau explains how to read each section in its Loan Estimate explainer, and the fee lines here follow that document.
Then enter the two decision inputs: the monthly saving the new loan gives you against the old one, and how long you realistically plan to stay. The result gives you the total, its percentage of the loan, an itemized table, the roll-in comparison, and the break-even verdict in one pass. If you only want the percentage check on its own, the closing cost percentage calculator isolates that one ratio.
The formulas behind the total, the roll-in, and the break-even
Quick mode is one multiplication. Itemized mode is a sum of nine lines, two of them percentages of the loan and one of them computed from time: prepaid interest is the loan times the annual rate, divided by 365, times the days from closing to month end. The roll-in comparison amortizes the fee total itself as a small loan at your new rate and term, which is exactly what happens when the fees join your balance. The break-even is the formula the Federal Reserve uses in its refinancing guide: total costs divided by monthly savings.
One caution the formula cannot fix: a monthly saving created mainly by stretching the loan back out to 30 years is partly borrowed from your future self. The break-even still works as a cost test, but before you celebrate a long break-even win, check the purchase decision itself with the buy a home calculator and the payment against your income with the affordability ratio calculator.
Worked example: $9,000 of costs against $200 a month
The calculator is pre-filled with this case, and every figure below is what it returns in quick mode.
| Measure | Result | How it is derived |
|---|---|---|
| Total closing costs | $9,000.00 | $300,000 x 3% |
| Share of the loan | 3.00% | Inside the typical 2 to 5% range |
| Extra interest if rolled in | $10,843.99 | Fee total amortized at 6.2% over 30 years |
| Break-even | 45.0 months | $9,000 / $200 a month |
| Kept after an 8-year stay | $10,200.00 | $200 x 96 months, minus $9,000 |
Switch the same loan to itemized mode with the pre-filled defaults (0.5% origination, a $600 appraisal, a $75 credit report, $1,200 of title charges, $150 of recording charges, and 15 days of prepaid interest at 6.2%) and the total drops to $4,289.38, or 1.43% of the loan, with prepaid interest of $764.38 inside it. The break-even at $200 a month falls to about 21.4 months. That gap between the two modes is the lesson: a percentage quote is a starting point, and the itemized list is where a refinance is actually won or lost.
Which refinance fees you can actually negotiate
Lender fees are the flexible ones. Origination, processing, and underwriting charges move when you shop competing lenders, and they are the first thing waived in a no-closing-cost offer. Third-party fees such as appraisal, title, and recording are less flexible, though you can shop for your own title company in most states. Government recording charges are fixed. A no-closing-cost refinance is not free: the lender covers the fees in exchange for a rate roughly 0.125 to 0.25 points higher, which adds roughly $30 to $60 a month and only wins if you sell or refinance again within about three to four years.
Discount points deserve the same break-even treatment as the whole refinance. One point costs 1% of the loan and buys the rate down; whether that trade pays depends entirely on how long you keep the loan, which is why points sit inside the itemized total here instead of being treated as a separate decision.
Pay the fees upfront or roll them into the loan?
Pay upfront
- You pay the fee amount once: $9,000 in the worked example, not $19,843.99.
- Your balance and payment stay lower from day one.
- Best when you have the cash and will stay past the break-even point.
- The cash is gone if you are forced to move early.
Roll into the loan
- No cash needed at closing, which preserves your reserves.
- You pay interest on the fees for the full term, more than doubling their cost over 30 years.
- Best when cash is tight or you expect to sell or refinance again within about five years.
- A higher balance can matter if you are near an equity or loan-to-value threshold.
The calculator runs this comparison with your own rate and term rather than a generic warning, because the interest on rolled fees is brutally sensitive to both: the same $9,000 rolled into a 15-year loan costs far less than half of what the 30-year roll-in costs.
What competing refinance calculators miss
Most refinance tools reviewed for this page split the job in two or answer a different question entirely, and the splits hide the decision.
Miss 1: cost total and break-even on separate pages. Totals-only tools never ask how long you will stay, and break-even tools make you type in a closing cost total you had to get somewhere else. Here the total, the break-even month, and the stay verdict come from one set of inputs.
Miss 2: no roll-in price tag. Payment-focused calculators show the new monthly payment and stop, so rolling $9,000 of fees in looks painless. This calculator prices the roll-in explicitly: about $10,843.99 of extra interest on the worked example.
Miss 3: a single percentage instead of the fee list. A flat 3% assumption cannot tell you that the itemized defaults total 1.43%, or which line is inflated. Itemized mode can, and it computes prepaid interest from your rate and closing days instead of folding in a flat guess.
One honest limit: this is a cost and break-even tool, not a full refinance comparison. It takes your monthly saving as an input rather than computing both loans payment by payment, so it will not catch a term-reset that inflates lifetime interest. Use it on the cost side of a quote you already have.
Frequently Asked Questions
Typically 2 to 5% of the loan amount. On a $300,000 loan that is $6,000 to $15,000. The largest lines are usually the origination charge, lender title insurance, and prepaid interest.
Origination fees, discount points, appraisal, credit report, title search and insurance, recording and government charges, prepaid interest, and escrow prepaids for taxes and insurance. The itemized mode on this page covers each one.
Origination, processing, and underwriting fees are the most negotiable, sometimes waived entirely. You can also shop for your own title company. Appraisal, credit report, and government recording fees are largely fixed.
No. The lender absorbs the fees in exchange for a rate about 0.125 to 0.25 points higher. That adds roughly $30 to $60 a month, which only makes sense if you sell or refinance again within three to four years.
Rolling avoids upfront cash but you pay interest on the fees for the whole term: $9,000 rolled into a 30-year loan at 6.2% adds about $10,843.99 in interest. Roll when cash is tight or you will move within five years; pay upfront when you will stay past break-even.
Prepaid interest that buys your rate down. One point costs 1% of the loan. Points only pay off if you keep the loan long enough for the lower payment to recover their cost, which the break-even math on this page checks.
Costs paid in advance at closing: daily interest from the closing date to month end, plus escrow deposits for property taxes and homeowners insurance. They are real cash due at closing even though they are not lender fees.
Compare Section A lender fees on the Loan Estimate across at least three lenders, since that is where quotes vary most. Then run the total through the break-even math with your monthly savings and planned stay before signing.
