Here’s the exact math one Virginia homeowner ran with me last week: a $340,000 balance at 7.1%, refinancing into a new 30-year rate-and-term loan at 5.9% based on the Freddie Mac Primary Mortgage Market Survey as of September 2026. Closing costs came in at $6,800. The payment dropped about $265 a month, which put the break-even point at 26 months. If she stays in the home five years past that break-even, the net savings land around $9,300. That’s not a hunch, that’s a flowchart with real numbers plugged into every box.
By the end of this guide you’ll have built the same kind of personal refinance decision flowchart, one that tells you in dollars and months whether refinancing makes sense right now, instead of relying on a rule of thumb that doesn’t fit your loan. Before you start, pull your current mortgage statement (balance, rate, payment, PMI status) and have last month’s Freddie Mac PMMS rate handy. Duane Buziak, NMLS #1110647, has run this same math for homeowners across Virginia, Maryland, and the Carolinas, and the process below is the one I use at my own kitchen table.
- Step 1: Pull Your Current Loan Numbers
- Step 2: Compare Your Rate to Today’s Market
- Step 3: Get a Real Closing Cost Estimate
- Step 4: Calculate Your Break-Even Month
- Step 5: Map How Long You Plan to Stay
- Step 6: Add Your PMI, Cash-Out, or Debt Branches
- Step 7: Follow the Flowchart to a Final Decision
Step 1: Pull Your Current Loan Numbers
Every box on your flowchart depends on the numbers in this step being exact, not approximate. Log into your servicer’s portal or call for a payoff quote and write down four things: your exact current balance (not the number from your last statement’s “principal balance” line, which can lag your actual payoff by a payment or two), your note rate, your monthly principal and interest payment, and whether you’re still paying mortgage insurance. If you’re not sure whether you’re paying PMI or an FHA mortgage insurance premium, check line items on your monthly statement, both show up separately from taxes and homeowners insurance in escrow.
Next, confirm your loan type: conventional, FHA, VA, or USDA. This matters more than most homeowners realize, because it determines which refinance path even applies to you. A VA loan holder may qualify for an Interest Rate Reduction Refinance Loan, detailed on va.gov, with reduced documentation. An FHA borrower may have access to a streamline refinance under guidelines published on hud.gov. Conventional borrowers follow standard rate-and-term or cash-out rules with full income and asset documentation.
The most common mistake at this stage is using an estimated balance instead of the exact payoff figure from your servicer. A $3,000 or $4,000 gap between your guess and the real number doesn’t sound like much, but it shifts your break-even calculation by a month or two, and it can be the difference between a flowchart that says “refinance now” and one that says “wait.” Get the real number before you build anything else on top of it.
Step 2: Compare Your Rate to Today’s Market
With your current rate in hand, check it against the current market. The Freddie Mac PMMS publishes weekly average rates for conventional 30-year and 15-year mortgages, and it’s the same benchmark I use with clients because it’s free, updated weekly, and not tied to any single lender’s marketing rate. Continuing the example from the introduction, a homeowner sitting at 7.1% on a $340,000 balance who checks the survey and sees conventional 30-year rates near 5.9% has a real, math-backed gap worth investigating, not just a headline number from an ad.
Here’s the branch logic for this box on your flowchart: a rate gap under roughly 0.75% rarely clears closing costs fast enough to matter, especially once you factor in a five-year total cost comparison in Step 4. That doesn’t mean a smaller gap is never worth it, sometimes it is, particularly on larger balances where even a quarter-point saves real money each month. But as a general branch rule, anything under 0.75% needs the full break-even math before you get excited about it.
One nuance worth building into your flowchart: government-backed streamline programs don’t always require the same rate improvement conventional refis do. VA IRRRLs and FHA streamline refinances are designed around a “net tangible benefit” test rather than a strict rate threshold, so a borrower with an FHA or VA loan may qualify for a beneficial refinance with a smaller rate drop than a conventional borrower would need to justify the same move. If you hold a government-backed loan, add a separate branch for that streamline path before you run the conventional math.
Step 3: Get a Real Closing Cost Estimate
Guessing at closing costs is where most homemade refinance spreadsheets fall apart. Request a soft-pull pre-qualification, one that checks your credit without a hard inquiry, so you get an actual lender estimate instead of a national average pulled from an article. A soft pull won’t touch your credit score, so there’s no reason to skip this step out of fear it’ll ding you.
Continuing the worked example, closing costs on that $340,000 refinance came to $6,800, covering the appraisal, title work, lender fees, and prepaid escrow items. When you get your own estimate, ask specifically about no-out-of-pocket closing options, structures that roll costs into the new rate or loan balance instead of requiring cash at the table. This doesn’t make the costs disappear, it just changes how you pay them, and your flowchart should account for whichever version you actually choose since it changes your break-even math.
This is also a natural branch point. If a lender can’t get you within a few hundred dollars of a real closing cost figure, based on your actual loan amount, property, and state, stop here and get another quote before moving to Step 4. Running break-even math on a placeholder number defeats the purpose of building a flowchart in the first place. A broker who shops your loan across hundreds of wholesale lenders can usually tighten that estimate faster than a single direct lender working off one rate sheet, since a broker can compare fee structures side by side instead of guessing at what one bank will charge.
Step 4: Calculate Your Break-Even Month
This is the box that actually drives the decision. The formula is simple:
Closing costs ÷ monthly payment savings = break-even month
Working the numbers from our example: dropping from 7.1% to 5.9% on a $340,000 balance cuts the monthly principal and interest payment by about $265. Divide the $6,800 in closing costs by that $265 monthly savings, and you get roughly 26 months to break even. That’s the point where your cumulative savings finally overtake what you spent to get the new loan.
Don’t stop at break-even, though. Run a five-year total cost check too. In this example, once you clear month 26, you’ve got 34 more months of full savings inside a five-year window. At $265 a month, that’s roughly $9,000 in additional savings, plus the money saved during the ramp-up to break-even, netting out to approximately $9,300 saved over five years after accounting for closing costs. That net number, not just the break-even month by itself, is what belongs on your flowchart’s “yes” branch, because it tells you the actual dollar payoff, not just when you start being ahead.
The table below shows how this specific example compares side by side, current loan versus refinanced loan:
| Loan Detail | Current Loan | Refinanced Loan |
|---|---|---|
| Balance | $340,000 | $340,000 (plus rolled costs if chosen) |
| Interest Rate | 7.1% | 5.9% |
| Monthly Principal & Interest | $2,285 | $2,020 |
| Monthly Savings | N/A | ~$265 |
| Closing Costs | N/A | $6,800 |
| Break-Even Month | N/A | ~26 months |
| Net 5-Year Savings (post-cost) | N/A | ~$9,300 |
Note the table content is illustrative math based on the example figures, not a quote, actual numbers depend on your credit profile, loan program, and the rate available the day you lock.
Step 5: Map How Long You Plan to Stay
A favorable break-even month only matters if you’re still in the house long enough to benefit from it. In the example, a break-even of 26 months paired with a plan to stay 3 or more years points your flowchart toward “refinance now.” If you expect to sell or move before month 26, the same math points to “wait or skip,” even though the rate gap itself looked appealing back in Step 2.
Be honest about life events that could shorten your real timeline even if you don’t currently plan to move: a possible job relocation, an aging parent who might need you closer, a downsizing plan once kids are out of the house, or a retirement date that could put your home on the market sooner than expected. These aren’t hypothetical boxes on a chart, they’re the difference between a refinance that pays off and one that costs you money on your way out the door.
For a consumer-facing cross-check on how break-even timing factors into a refinance decision, the Consumer Financial Protection Bureau’s refinancing guide walks through the same logic in plain language and is worth a read if you want a second source confirming the approach before you commit.
Step 6: Add Your PMI, Cash-Out, or Debt Branches
Your flowchart isn’t finished once you’ve handled the rate-and-term branch. Most homeowners have at least one more decision hiding in their loan, and each one deserves its own branch tied to a real dollar outcome, not just a yes or no.
- PMI removal branch: If you’ve built more than 20% equity, add a branch checking whether a refinance also eliminates private mortgage insurance. The Homeowners Protection Act sets automatic termination at 22% equity and allows borrower-requested cancellation at 20%, guidance the CFPB explains in detail. If a refinance drops your loan-to-value below that threshold, factor the monthly PMI savings directly into your break-even formula from Step 4, it can meaningfully shorten your payback period.
- Cash-out or debt consolidation branch: If part of your goal is pulling equity out to consolidate debt, add a branch comparing cash-out refinance terms against a home equity line of credit before committing to either. Remember that a conventional cash-out refinance caps at 90% loan-to-value, while a VA cash-out refinance can reach 100% LTV for eligible veteran borrowers. These are different products with different structures, don’t run the same break-even formula for a HELOC that you’d use for a full cash-out refinance, since a HELOC typically carries no first-mortgage closing costs but a variable rate.
- Combined branch: If more than one of these applies (say, you want to remove PMI and also access some equity), run each dollar outcome separately, then combine them into a single blended break-even figure. That keeps your flowchart honest instead of stacking assumptions on top of each other.
The rule for every added branch is the same: it needs to end in a number, not a feeling. “Refinancing would probably help with my credit cards” isn’t a flowchart output. “Consolidating $18,000 in credit card debt at 22% APR into a cash-out refi at 5.9% saves roughly $310 a month” is.
Step 7: Follow the Flowchart to a Final Decision
Once every box is filled in with real numbers, the decision usually makes itself. If your break-even is favorable and your stay-timeline clears it comfortably, the next move is locking your rate and moving into a full application. At this stage you’re not guessing anymore, you’re executing a plan you’ve already tested against your own numbers.
If the numbers come out close, don’t force a decision. A break-even of 30 months against a stay-timeline of exactly 3 years is a genuine toss-up, not a clear “yes.” In that situation, ask for a second soft-pull comparison in 30 to 60 days as rates move, rather than guessing which direction they’ll go. Rates shift week to week on the PMMS, and a small move in either direction can flip a marginal decision into a clear one.
Save your flowchart and every input you used to build it: balance, rate, closing cost estimate, break-even month, and stay-timeline. That way, whenever the Freddie Mac PMMS shows a meaningful rate shift, you can rerun the same math in five minutes instead of starting from scratch. As a data point for Virginia homeowners specifically, Henrico County’s median assessed home value and conforming loan limits are tracked through the FHFA conforming loan limit lookup and the Henrico County Real Estate Assessment records, both useful if your refinance decision also depends on whether your loan amount stays within conforming limits.
Refinance Decision Flowchart: Frequently Asked Questions
What is a refinance break-even month?
It’s the number of months it takes for your monthly payment savings to equal the closing costs you paid to refinance. You calculate it by dividing total closing costs by your monthly payment savings.
Is Duane Buziak a mortgage broker or a mortgage lender?
Both. Duane Buziak operates as a licensed mortgage broker, shopping your loan across hundreds of wholesale lenders to match your specific scenario, while also having in-house and correspondent funding capability through Coast2Coast Mortgage. That combination lets him compare rate sheets like a broker while still controlling the process like a direct lender.
What rate drop makes refinancing worth it?
There’s no universal number, but a gap under roughly 0.75% rarely clears closing costs fast enough to matter on a conventional rate-and-term refinance. VA IRRRL and FHA streamline refinances often qualify with a smaller improvement because they’re evaluated on net tangible benefit rather than a strict rate threshold.
Does a soft-pull pre-qualification affect my credit score?
No. A soft-pull pre-qualification checks your credit without a hard inquiry, so it does not affect your credit score, which makes it a low-risk way to get real numbers before deciding whether to move forward.
How much are typical closing costs on a refinance?
Closing costs vary by loan size, state, and lender, but they commonly run in the low thousands of dollars, covering appraisal, title, and lender fees. Ask for no-out-of-pocket closing options if you’d rather roll those costs into your rate or balance instead of paying cash at closing.
What’s the difference between a cash-out refinance and a HELOC?
A cash-out refinance replaces your existing mortgage with a new, larger loan and gives you the difference in cash, with conventional cash-out capped at 90% loan-to-value and VA cash-out able to reach 100% LTV. A HELOC is a separate line of credit on top of your existing mortgage, typically with a variable rate and different closing cost structure.
When can I remove PMI through a refinance?
Under the Homeowners Protection Act, PMI can typically be cancelled once you reach 20% equity by request or 22% equity automatically. If a refinance brings your loan-to-value below those thresholds, removing PMI adds to your monthly savings and shortens your break-even timeline.
What documents do I need before building my refinance flowchart?
You’ll want your exact payoff balance from your servicer, your current note rate, your monthly principal and interest payment, your PMI or mortgage insurance status, and your loan type (conventional, FHA, VA, or USDA).
Should I refinance now or wait for rates to drop further?
That depends on your specific break-even month and how long you plan to stay in the home, not on rate predictions. If your calculated break-even clears comfortably within your stay-timeline, waiting for a further drop risks missing savings you could be capturing today.
How often should I rerun my refinance decision flowchart?
Rerun it anytime your rate gap widens, your home equity crosses a PMI threshold, or your stay-timeline changes, and check it again whenever the Freddie Mac PMMS shows a meaningful weekly rate move.

Rerun this flowchart whenever your rate gap, home equity, or timeline changes. Rates move weekly, life circumstances shift, and a flowchart built on stale numbers can point you in the wrong direction just as easily as no flowchart at all. Keep a soft-pull pre-qualification in your back pocket so you always have current numbers ready when it’s time to check the boxes again.
