A rate and term refinance replaces your current mortgage with a new loan that changes your interest rate, your repayment length, or both, without taking cash out of your equity. Whether it saves you money depends on your total monthly cost and on how long you keep the home, not on the rate drop alone. This article walks through a worked total-cost example, a side-by-side comparison of refinance paths, and a break-even test so you can judge your own situation.

How a Rate and Term Refinance Works (and What It Is Not)
In a rate and term refinance, a new loan pays off your existing balance in full. The principal stays essentially the same. The only extra money in the transaction covers closing costs and escrow adjustments, such as funding a fresh tax and insurance account. You are changing the terms of the debt, not borrowing more against the house.
That separates it from a cash-out refinance, where you borrow more than you owe and keep the difference. Duane Buziak arranges cash-out refinances up to 90% of home value, but they carry different pricing and underwriting than a straight rate and term loan, and the larger balance changes your math. Treat them as a separate decision.
Government streamline programs are a third path. The FHA Streamline and the VA IRRRL (Interest Rate Reduction Refinance Loan) are built for homeowners who already have an FHA or VA loan. They typically offer lighter documentation, and sometimes no appraisal, but each has its own rules on benefit tests, seasoning, fees, and eligibility. Verify current requirements on HUD.gov and VA.gov before you count on one, and see the streamline refinance eligibility requirements for a closer look.
The most common misconception is that a lower rate always saves money. If you are seven years into a 30-year loan and refinance into a new 30-year, you restart the clock. A lower payment can come with just as much, or more, interest paid over the life of the loan. The rate is only one input; the remaining term matters just as much.
The Four Goals a Rate and Term Refinance Can Serve
Lower the rate on the same term
This is the classic case. On an illustrative $320,000 balance, moving from 7.00% to 6.00% on a 30-year term drops principal and interest from about $2,129 to about $1,919, roughly $210 a month. Compare current market rates against a published benchmark such as Freddie Mac’s Primary Mortgage Market Survey, which updates weekly. Your own rate depends on credit, loan-to-value, and property type, and nothing here is a rate quote. For a deeper look at what moves your number, read about mortgage rate factors.
Shorten the term
Moving from a 30-year to a 15- or 20-year loan raises the payment but cuts lifetime interest sharply. On the same illustrative balance at 6.00%, a 20-year term runs about $2,293 a month and costs roughly $230,000 in total interest. That is far less than a 30-year at the same rate. Choose this only if the higher payment fits comfortably in your budget.
Move from adjustable to fixed
If your adjustable-rate mortgage is nearing a reset, a fixed rate removes the risk of a payment jump. You may pay a slightly higher starting rate than the ARM’s teaser, but you buy certainty. Many homeowners do this when they plan to stay beyond the ARM’s fixed period.
Remove mortgage insurance
If you have an FHA loan, mortgage insurance premiums may last for the life of the loan, depending on your down payment and origination date. If you have conventional PMI, it may linger because of how your servicer measures value. When home values or your payments have built enough equity, a refinance into a conventional loan at 80% loan-to-value or less can eliminate the insurance line entirely. Section 4 puts numbers on that.
Total Cost of Ownership Worksheet: Before vs. After a Refinance
A payment number alone hides most of what you pay each month. Here is a line-by-line worksheet. Every figure below is illustrative, not a quote.
Assume a $400,000 home, a $320,000 balance, a current 30-year loan at 7.00%, and a refinance into a new 30-year at 6.00%. For the locality, use Henrico County, Virginia. The county has published a real estate rate of $0.85 per $100 of assessed value in recent years, but rates are set annually, so confirm the current figure on the Henrico County real estate assessments page before relying on it. At $0.85 per $100, a $400,000 assessment produces $3,400 a year, or about $283 a month.
- Principal and interest: $2,129 before; $1,919 after.
- Property tax: $283 before; $283 after (the refinance does not change your assessment).
- Homeowners insurance (assumed $1,800 a year): $150 before; $150 after.
- PMI (assumed 0.50% of the loan a year): $133 before; $0 after, because the new loan sits at 80% of a $400,000 appraisal.
- Escrow total (tax plus insurance): $433 before; $433 after.
- All-in monthly cost: about $2,696 before; about $2,352 after.
The refinance saves about $344 a month, and every dollar of it comes from two lines: principal and interest ($210) and PMI ($133). Taxes and insurance do not move. This is why a quote that shows only the new payment can mislead you in either direction. Make sure you compare the full monthly cost, and note that the PMI savings in this example depend on a new appraisal supporting the value. If you want to see how these lines work, here is a primer on the mortgage escrow account.
Break-Even Math and PMI Removal: When Refinancing Pays Off
Finding your break-even point
Divide your total closing costs by your monthly savings. If closing costs on the illustrative loan are $6,400 (about 2% of $320,000) and the all-in savings are $344, you recoup the cost in about 19 months. If you counted only the $210 in principal and interest savings, the figure stretches to about 30 months. Compare that number to how long you realistically expect to stay. Selling in year two with a 30-month break-even means the refinance cost you money. Closing costs are real, and they vary by loan; ask about no-out-of-pocket closing options if you prefer to avoid paying at the table, and understand how that affects the rate. It also helps to know what goes into the mortgage origination fee before comparing quotes.
PMI removal math
Conventional PMI is built around an 80% loan-to-value target. On a $400,000 home, 80% is $320,000, so you need $80,000 in equity (20%). Under the Homeowners Protection Act, PMI on many conventional loans must end automatically when your balance is scheduled to reach 78% of the original value, and you can request cancellation at 80% if you meet conditions such as a good payment history. Details vary by loan and servicer, so confirm the rules at consumerfinance.gov. If cancellation is not available to you, refinancing on a fresh appraisal can reach the same result.
The cost of resetting the term
Suppose you have 27 years left on the 7.00% loan. Paying it to the end costs roughly $370,000 in interest. A new 30-year at 6.00% costs roughly $371,000. The payment is lower, but total interest is nearly identical, so you are essentially buying monthly cash flow with three extra years. A 20-year at 6.00% cuts interest to about $230,000 at a payment near the old one. Which version is right depends on whether you want lower payments or lower lifetime cost.

Comparison Table: Refinance Paths and Where to Get Them
Requirements change, so check current rules with HUD.gov and VA.gov before you commit. The comparison below reflects general program design as of late 2026.
Refinance paths side by side
- Rate and term: Purpose is a new rate, term, or loan type with no cash out. Equity needed is typically enough for a conforming loan-to-value, with 20% giving PMI removal. Credit and appraisal: full credit review and usually an appraisal.
- Cash-out: Purpose is turning equity into cash. Equity needed is enough to stay within the program’s limit, up to 90% of value through Duane Buziak. Credit and appraisal: full review and an appraisal, with pricing that often reflects the higher balance.
- FHA Streamline: Purpose is refinancing an existing FHA loan, typically with a required net tangible benefit. Equity needed is often minimal. Credit and appraisal: documentation is often reduced, and an appraisal may not be required; verify current rules.
- VA IRRRL: Purpose is lowering the rate on an existing VA loan. Equity needed is not typically the focus. Credit and appraisal: streamlined, often without an appraisal, with a funding fee that may apply; verify eligibility.
How you shop matters too
- A mortgage broker: Duane Buziak can compare options from hundreds of wholesale sources at once, so you see more pricing from one application process. Here are some tips on how to shop mortgage rates from multiple lenders.
- A single direct provider: Companies such as Rocket, Veterans United, and Movement offer their own products and streamlined online experiences. Veterans United is widely known for VA lending. Offerings and pricing change, and you see only that one company’s loan options. For one example, see BetterMortgageRates vs Rocket Mortgage.
- Other providers: Banks, credit unions, and regional companies each have their own programs. Ask any of them for a written Loan Estimate so the comparison is apples to apples.
How to Start Without Hurting Your Credit
You do not need a hard inquiry just to see where you stand. A soft credit pull mortgage review lets Duane Buziak check your options through NoTouch Credit Pull using Vantage Score 4.0, with no credit hit at the exploration stage. As a soft pull mortgage broker, he can show you realistic scenarios first. A hard pull comes later, when you formally apply and choose to move forward.
- Gather your current mortgage statement. Note your balance, rate, remaining term, and whether PMI or mortgage insurance is included.
- Estimate your home value. Recent nearby sales give a reasonable starting point; an appraisal later will settle it.
- Set your goal. Lower payment, shorter term, fixed rate, or insurance removal. Each goal leads to a different best loan.
- Compare quotes on identical terms. Same loan type, same term, same lock period, same assumptions about points.
- Lock the rate when the numbers pass your break-even test.
When Loan Estimates arrive, compare page one for rate, monthly payment, and estimated cash to close, then page two for origination charges and third-party fees. Match the interest rate against the points paid, since a lower rate bought with mortgage points changes your break-even. A rate lock holds your quoted rate for a set period while the loan is processed, so market moves during that window do not change it. Duane Buziak is available 24/7 and can often move quickly toward closing, though timelines depend on appraisal, documents, and underwriting and are never guaranteed.
A Refinance Is Worth It Only If You Stay Past Break-Even
The decision rule is simple: if your break-even point arrives before you expect to move or refinance again, the refinance likely pays off. If it does not, keep your current loan. Run the worksheet with your own numbers, include taxes, insurance, and PMI, and compare the term you would reset to.
