A refinance closing costs calculator can tell you in about ten minutes whether a refinance is worth pursuing, but only if you feed it the right numbers and read the output correctly. Duane Buziak, NMLS #1110647, walks you through seven steps: set your inputs, include every real cost, model rate scenarios, choose how to pay, find your break-even point, compare lenders, and check the estimate against a Loan Estimate. Before you start, have your latest mortgage statement, a rough home value, your credit score range, and any Loan Estimate you already hold. The result is a clear answer to what a refinance costs and whether it pays off for the time you plan to stay.
Step 1: Gather Your Current Loan and Property Numbers
Decide your goal before you type anything: a lower payment, a shorter term, cash out, or removing mortgage insurance. The goal changes which costs apply. A cash-out refinance, for example, may carry different pricing and appraisal requirements than a straight rate-and-term refinance.
Then collect these inputs:
- Current payoff balance, not your original loan amount.
- Current interest rate and remaining term in months.
- Monthly principal and interest, excluding taxes and insurance.
- Estimated home value.
- Credit score range, such as 680 to 719 or 740 and up.
Get the payoff figure from your servicer rather than copying the balance on your statement. The statement balance leaves out interest that has accrued since your last payment, so it can understate what you will owe at closing. Servicers can issue a payoff quote, usually good for a set number of days.
The common mistake is entering the original loan amount or a Zillow-style value as if it were fact. Online value estimates can be off by a meaningful margin in either direction. Treat your home value as an estimate until an appraisal confirms it, and run the calculator with a slightly lower value too. A lower value raises your loan-to-value ratio (LTV, the loan balance divided by the home’s value), which can change pricing and whether mortgage insurance applies.
Step 2: Enter the Costs a Refinance Closing Costs Calculator Should Include
A good calculator separates three categories, and mixing them is where most estimates go wrong.
True closing costs are fees paid for services: lender origination charges, the appraisal, the title search and lender’s title insurance, recording fees, and the credit report. Some are charged by the lender and some by third parties.
Prepaid items are not fees. They are your own money paid in advance: interest from closing to the end of that month, the first year of homeowners insurance if not already paid, and any property tax and insurance deposits to open the escrow account. Calculators often ignore these, which makes cash to close look smaller than it is. Others add them to the fees as though they were a cost, which makes the refinance look worse than it is. If you already have an escrow account, your old servicer refunds that balance after payoff, which offsets the new deposit.
Check that the calculator lets you edit each line. A flat percentage of the loan amount is only a starting point, because title costs, recording fees, and appraisal fees vary by property and location. Figures you may see quoted for typical percentages should be tied to a named source and year; this guide leaves them out because your own Loan Estimate is the number that matters.
The CFPB explains each section of the form you will eventually receive in its guides to the Loan Estimate and the Closing Disclosure. Match your calculator’s line items to those headings so nothing is missed or counted twice.
Step 3: Choose Your New Rate, Term, and Loan Type
Run at least two rate cases: a base case and one slightly higher. Rates move daily, and a quote you see today may not be the rate you lock. For a general market reference, the Freddie Mac Primary Mortgage Market Survey publishes weekly average rates, which is useful context but not an offer or a prediction of what you will be quoted.
Keep the comparison fair. Model the same loan type and term across cases, then change one variable at a time. A shorter term, say 15 years instead of 30, raises your monthly payment even though it cuts total interest sharply. If your goal is a lower payment, a shorter term may defeat it.
Program choice changes the cost structure. Conventional, FHA, VA, and jumbo loans carry different fee and mortgage insurance setups, so select the right one in the calculator. Limits matter if you are taking cash out:
- Conventional cash-out refinances top out at 90% LTV (see Fannie Mae’s Selling Guide for current eligibility rules).
- VA cash-out refinances allow up to 100% LTV.
For VA scenarios, Duane Buziak pulls your Certificate of Eligibility (COE) electronically using your Social Security number and date of birth. Remaining (bonus, or second-tier) entitlement is worked out by taking the county loan limit times 25% for the maximum guarantee, subtracting entitlement already in use, and multiplying the result by four to get the zero-down purchase limit.
Step 4: Decide How You Will Pay the Closing Costs
You have three choices, and each changes the calculator output differently.
- Pay cash at closing. Your balance and payment stay lowest, but cash due is highest.
- Roll costs into the new loan. Cash due drops, but the balance rises, so both the payment and total interest go up. Rolling in is not free; you are borrowing the costs and paying interest on them. Confirm the new balance still fits within your program’s LTV limit.
- Take a lender credit. The lender offsets some or all costs, and you accept a higher rate in exchange. The credit is paid for through that rate, for as long as you hold the loan.
Some borrowers use the phrase “zero closing costs,” but that is not accurate. What exists are no-out-of-pocket closing options, where costs are financed or credited rather than paid in cash. Someone pays for them either way.
Enter each option as its own scenario. Many calculators show only one, so you may need to run it three times with a different balance or rate each time.
One practical point: through an independent broker, wholesale pricing from different lenders can change how much credit a given rate produces. Duane Buziak can compare that across lenders on the same day, though no rate or credit amount can be promised before your scenario is priced.
Step 5: Run the Worked Example and Find Your Break-Even Point
This is a hypothetical illustration, not a quote or an offer. Suppose you owe $320,000 on a 30-year loan at 7.00%, with principal and interest of about $2,129. You refinance to a 30-year loan at 6.25%, where principal and interest on $320,000 is about $1,970. Total closing costs are $6,400.
Paying cash:
- Monthly savings: $2,129 minus $1,970 = about $159.
- Break-even: $6,400 divided by $159 = about 40 months, or just over three years and four months.
- If you keep the home beyond that, the savings are real. If you sell in two years, you lose money on the refinance.
Rolling costs in: the new balance becomes $326,400, and the payment at 6.25% rises to about $2,010. Monthly savings fall to about $119, but nothing is due in cash. The extra $40 a month is the price of financing the $6,400. Over a full 30 years that adds up to about $14,400, more than double the original costs.
The term-reset mistake. Total interest tells a different story from payment savings. Using the figures above, 360 payments of $2,129 total about $766,400, or about $446,400 in interest. Under the new loan, 360 payments of $1,970 total about $709,300, or about $389,300 in interest.
That comparison assumes you were at the start of your term. Now suppose you are eight years into a 30-year loan with a $320,000 balance still owed at 7.00% and 22 years left. Your payment would be closer to $2,379, with about $308,000 in remaining interest. Refinancing into a new 30-year term at 6.25% drops the payment to $1,970 but brings about $389,000 in interest, roughly $81,000 more. A 22-year term at 6.25% (about $2,234 monthly) would cut interest to roughly $270,000 instead. A lower payment is not the same as savings once the clock restarts.
Step 6: Compare Lender Scenarios Side by Side in a Table
A calculator models one lender’s costs at a time. The more useful comparison puts several wholesale lenders next to each other. Duane Buziak is an independent broker with wholesale relationships with the lenders below, and is not affiliated with, endorsed by, or a division of any of them. The table reflects each lender’s general positioning only; it does not predict pricing or approval.
| Wholesale lender | General positioning | Refinance scenario to ask about | Pricing |
|---|---|---|---|
| The Loan Store | Lean, aggressive agency-product pricing | Conventional rate-and-term refinance | Priced per scenario, no promise |
| LoanUnited | Lean, aggressive agency-product pricing | Conventional rate-and-term refinance | Priced per scenario, no promise |
| NexBank | Jumbo and institutional-backed pricing | Jumbo refinance above conforming limits | Priced per scenario, no promise |
| LoanStream Mortgage | Broad one-stop specialty shop | Scenarios that do not fit a standard agency box | Priced per scenario, no promise |
The second table is your own. Using the hypothetical from Step 5 (the lender-credit rate of 6.50% is an assumed illustration):
| Scenario | Rate | Balance | Approx. P&I | Cash due for costs | Monthly savings | Break-even |
|---|---|---|---|---|---|---|
| Pay cash | 6.25% | $320,000 | $1,970 | $6,400 | $159 | About 40 months |
| Roll costs in | 6.25% | $326,400 | $2,010 | $0 | $119 | No upfront cash; costs are financed |
| Lender credit | 6.50% | $320,000 | $2,023 | $0 | $106 | No upfront cash; costs paid through rate |
Calling a single lender directly gets you that lender’s menu. An independent broker can price several wholesale lenders from one application, so you see the competing scenarios without submitting multiple credit pulls and applications of your own.
Step 7: Verify the Estimate Against a Loan Estimate and Lock
A calculator is an estimate. The Loan Estimate is the document that counts. Under CFPB guidance, lenders must deliver it within three business days of receiving your application; confirm the details on the CFPB’s Loan Estimate page.
Read it line by line:
- Section A: origination charges. Compare these across lenders first.
- Section B: services you cannot shop for, such as the appraisal and credit report.
- Section C: services you can shop for, such as title. Ask whether you can use another provider.
- Calculating Cash to Close: the bottom line. Check that it reflects your payoff, prepaids, escrow deposits, and any credit.
Feed these actual numbers back into your calculator and re-run Step 5. If the break-even moved, you now know by how much.

Frequently Asked Questions and Disclosures
How much are closing costs on a refinance?
Refinance closing costs depend on loan size, location, and lender, so no flat percentage is reliable. Your Loan Estimate shows the exact figure for your loan.
Can I roll closing costs into my refinance?
Yes, in many cases you can roll costs into the new balance. It raises your payment and total interest, and the new balance must stay within the program’s LTV limit.
What is a break-even point?
The break-even point is the number of months it takes monthly savings to repay your closing costs. Divide total costs by monthly savings.
Can I get UWM’s wholesale pricing through a broker?
Yes. Duane Buziak has a wholesale broker relationship with UWM and can price your scenario there. He is not affiliated with UWM, and pricing varies by scenario.
Does pre-qualification affect my credit?
Pre-qualification through Duane Buziak does not affect your credit. A full application and underwriting later involve a credit pull.
Are prepaids and escrow deposits closing costs?
No. Prepaids and escrow deposits are your own money paid in advance for interest, insurance, and taxes, not fees. They still count toward cash to close.
What is a lender credit?
A lender credit reduces your out-of-pocket costs in exchange for a higher interest rate. It is a no-out-of-pocket closing option, not free money.
How soon must a lender provide a Loan Estimate?
Lenders must provide a Loan Estimate within three business days of application, per CFPB guidance.
What is the maximum LTV for a cash-out refinance?
Conventional cash-out refinances allow a maximum of 90% LTV. VA cash-out refinances allow up to 100% LTV.
Can Duane Buziak compare PennyMac or Newrez for my refinance?
Yes. Duane Buziak has wholesale broker access to PennyMac, Newrez, and many other lenders, and can compare scenarios on one application. Terms and pricing depend on your loan.
