Calculate Your Rate-and-Term Refinance Savings
A rate-and-term refinance changes your interest rate, loan term, or both without adding to your loan balance. Enter your loan details below to see your exact savings.
How to Use This Calculator
The rate-and-term refinance calculator needs five inputs. Here is how to find each one accurately so your results reflect your real situation rather than rough estimates.
Current Loan Balance. This is the outstanding principal you owe today — not your original loan amount. Your mortgage statement shows this, or you can call your servicer for an exact payoff figure. If you recently made a payment, your servicer can give you a payoff amount that accounts for any accrued interest through a specific date.
Current Interest Rate. Find this on your mortgage note or your monthly statement. Enter the interest rate, not the APR. The APR (Annual Percentage Rate) includes fees and is always higher than the note rate. Using APR instead of the interest rate will distort your results.
Remaining Term. Calculate how many months remain on your current loan. If you started with a 30-year (360-month) mortgage and you are 3 years in, you have 324 months remaining. If you are 8 years in on a 30-year loan, you have 264 months left. Round to the nearest month.
New Interest Rate. Use the rate you have actually been quoted by a lender, not a rate you read in a news headline. Rate-and-term refinance rates vary based on your credit score, LTV, loan size, property type, and occupancy. Get a formal Loan Estimate from at least two or three lenders before entering a rate here — the spread between lender offers can be 0.25% to 0.5% or more on identical loan scenarios.
Closing Costs. Rate-and-term refinance closing costs typically range from 2% to 5% of the loan balance, though some lenders offer no-closing-cost options (which roll costs into the rate). Typical costs include origination fees, appraisal ($400–$600), title insurance, recording fees, and prepaid items like homeowners insurance and property taxes. The calculator accepts closing costs paid out of pocket. If you are rolling costs into the loan, use the No-Closing-Cost Refinance Calculator for a more accurate comparison. Use the Closing Cost Calculator to estimate costs if you don't have a formal Loan Estimate yet.
What Is a Rate-and-Term Refinance?
A rate-and-term refinance is the most common type of mortgage refinance. You replace your existing home loan with a new one at a better interest rate, a different term, or both — without extracting any cash from your home equity. Your new loan amount equals approximately your outstanding balance. If you roll closing costs into the loan, the new balance will be slightly higher, but no cash comes back to you at closing.
Unlike a cash-out refinance, a rate-and-term refinance is a pure restructuring of your debt. Lenders view it as lower risk because you are not increasing your principal beyond closing costs. As a result, rate-and-term refinances often carry slightly lower interest rates than cash-out refinances and may have less stringent qualification requirements.
The most common reasons to pursue a rate-and-term refinance include: interest rates have fallen significantly since your original loan, your credit score has improved substantially, you want to switch from an adjustable-rate to a fixed-rate mortgage, you want to shorten your term to build equity faster, or you want to extend your term to reduce monthly cash flow pressure. All of these goals are achievable through a rate-and-term refinance without touching your equity.
How It's Calculated
The rate-and-term refinance calculation involves comparing two loan scenarios on a monthly payment and total cost basis, then accounting for the closing cost hurdle you must overcome.
Monthly Savings = Current Payment − New Payment
Break-Even (months) = Closing Costs ÷ Monthly Savings
Net Lifetime Savings = (Current Total Interest − New Total Interest) − Closing Costs
Where P = loan balance, r = monthly rate (annual rate ÷ 12), n = number of monthly payments
The break-even point is the most critical output for most borrowers. It tells you how many months of lower payments you need to accumulate before you have recovered what you spent on closing costs. If you plan to sell or refinance again before that point, the refinance may not make financial sense. If you will stay well past break-even, the net savings can be substantial.
Real-World Example
Susan's Rate-and-Term Refinance
Susan has $295,000 remaining on her 2021 mortgage at 6.875% with 27 years (324 months) left. She qualifies for a new 25-year term at 5.99% with $6,200 in closing costs paid out of pocket.
Old monthly payment (6.875%, 324 months, $295,000): $2,063/mo
New monthly payment (5.99%, 300 months, $295,000): $1,893/mo
Monthly savings: $170/mo
Break-even: $6,200 ÷ $170 = 36.5 months (just over 3 years)
Old total interest over 324 months: $373,012
New total interest over 300 months: $273,900
Gross interest saved: $99,112
Net savings (minus closing costs): $92,912 over the life of the loan
Susan gets a lower rate AND shortens her remaining term by 2 years (from 27 to 25). She saves roughly $170 every month and will recoup her closing costs in 37 months. If she stays in the home 10+ more years, this refinance is a clear financial win.
When Does a Rate-and-Term Refinance Make Sense?
A rate-and-term refinance makes the strongest financial case when several conditions align. The more of these that apply to your situation, the more clearly refinancing makes sense.
Rate drop of 0.75% or more. While any rate reduction saves money in theory, the conventional wisdom is that a drop of at least 0.5% to 0.75% is needed to justify the transaction costs. The exact threshold depends on your loan balance — a 0.5% reduction on a $500,000 balance saves much more per month than on a $150,000 balance. Use this calculator with your actual numbers rather than relying on rules of thumb.
You plan to stay past break-even. If you know you will sell or move in 2 years and your break-even is 3 years, the refinance costs you money even if the rate is lower. Conversely, if your break-even is 18 months and you plan to stay 7 more years, you come out well ahead. The break-even calculation is the single most important output of this calculator for most borrowers.
Shortening the term to save interest. Even if your rate drops only modestly, refinancing from a 30-year to a 20-year or 15-year term can save tens of thousands in total interest. The tradeoff is a higher monthly payment. See the 15-Year vs 30-Year Calculator for a full side-by-side comparison before choosing a term.
Extending the term for cash flow relief. If your budget is tight, refinancing a 20-year loan into a new 30-year at a lower rate can dramatically reduce your required monthly payment, freeing up cash for other financial goals. You will pay more in total interest over the full term, but the improved monthly cash flow may be worth it. Use the Refinance Savings Calculator to model the full lifetime cost of this trade-off.
Switching from ARM to fixed rate. If your adjustable-rate mortgage is approaching the end of its fixed period or has already begun adjusting, a rate-and-term refinance into a fixed-rate loan eliminates payment uncertainty. See the ARM to Fixed Calculator for this specific scenario.
Your credit score has significantly improved. If your score has risen 60 to 100 points or more since your original loan, you may now qualify for a substantially better rate even if market rates haven't changed. This is one of the most underappreciated reasons to check refinance eligibility.
Common Rate-and-Term Refinance Scenarios
Scenario 1: Straightforward Rate Drop, Same Term
A borrower has $280,000 remaining at 7.25% with 26 years left. Current rate-and-term quotes are coming in at 6.25%. New payment on a 26-year term would be approximately $1,806/mo versus current $1,977/mo — a savings of $171/mo. With $5,600 in closing costs, break-even is 33 months. Net lifetime savings: approximately $47,000 after closing costs. This is a clean, straightforward case where refinancing clearly makes sense if they plan to stay 4+ years.
Scenario 2: Modest Rate Drop, Shortened Term
A borrower has $320,000 remaining at 6.75% with 25 years left. New rate available: 6.25% for a 20-year term. New payment: $2,340/mo versus current $2,227/mo — a payment increase of $113/month. But total interest on the 20-year loan: $241,600. Total remaining interest on the original 25-year loan: $348,200. Interest saved: $106,600. Despite paying $113 more per month, they save over $100,000 in total interest and pay off 5 years earlier. If cash flow can absorb the higher payment, this is an excellent outcome.
Scenario 3: Rate Drop with Term Extension for Cash Flow
A borrower has $210,000 remaining at 7.5% with 18 years left. They are stretched for cash and want lower payments. New rate: 6.75% for a new 30-year term. Old payment: $1,933/mo. New payment: $1,362/mo. Monthly savings: $571/mo. But total interest on the 30-year loan: $280,300 versus $161,900 remaining on the 18-year term. Extending the term costs an extra $118,400 in lifetime interest. The cash flow benefit is real and immediate, but it comes at a significant long-term cost. This borrower should weigh whether their financial constraint is temporary (suggesting refinance makes sense short-term) or permanent.
Tips and Strategies
Match your remaining term rather than automatically resetting to 30 years. If you have 22 years left on your current loan, refinancing into a new 30-year loan resets your amortization schedule and adds 8 years of payments. Consider selecting a 20-year or 22-year term to preserve your payoff timeline while still getting the rate benefit. Your monthly payment will be slightly higher than the 30-year option, but your total interest cost and payoff date will align better with your original plan.
Get Loan Estimates from at least three lenders. Federal law requires lenders to provide a standardized Loan Estimate within three business days of receiving your application. This document shows the interest rate, APR, monthly payment, and closing costs in a format that makes comparison straightforward. The difference between the best and worst offer among major lenders can easily be $200 to $400 per month on the same loan amount.
Ask about appraisal waiver eligibility. Fannie Mae's Desktop Underwriter and Freddie Mac's Loan Prospector systems sometimes allow lenders to waive the appraisal requirement on rate-and-term refinances when the property data is already in their systems and there is sufficient comparable sale data. An appraisal waiver saves you $400 to $600 and removes a potential roadblock if your home might appraise below expectations.
Check whether refinancing can eliminate PMI. If your original loan had PMI because your down payment was less than 20%, and your home's value has risen enough that a rate-and-term refinance puts you below 80% LTV on the new loan, you may be able to refinance into a loan without PMI. Use the LTV Calculator and PMI Removal Calculator to check whether this applies to you. The PMI savings alone can justify a refinance even with a modest rate improvement.
Lock your rate promptly once you decide. Mortgage rates change daily and can move 0.125% to 0.25% on a single day based on economic data releases or Federal Reserve communications. Once you have a competitive quote you're ready to accept, ask the lender about a rate lock — typically 30 to 60 days at no cost, or longer for a fee. Waiting to lock in hopes of a better rate can backfire if rates move against you.
Consider a no-closing-cost option if you may move or refinance again soon. If your break-even is 3 years but you are unsure whether you'll stay that long, a no-closing-cost refinance (where the lender absorbs closing costs in exchange for a slightly higher rate) might make more sense. Your monthly savings will be smaller, but you'll start benefiting immediately without any upfront risk. Use the No-Closing-Cost Refinance Calculator to compare the two approaches.
Frequently Asked Questions
What is the difference between a rate-and-term refinance and a cash-out refinance?
A rate-and-term refinance replaces your existing loan with a new one at a different rate or term, without changing your loan balance beyond rolled-in closing costs. A cash-out refinance creates a new larger loan and you receive the difference between the new loan and your old balance as cash at closing. Rate-and-term refinances are generally easier to qualify for, carry slightly lower rates, and are the right choice when your goal is purely to reduce your interest cost or adjust your repayment timeline — not to access equity. Use the Cash-Out Refinance Calculator if you also need to access your home's equity.
Do I need an appraisal for a rate-and-term refinance?
Most rate-and-term refinances require an appraisal, but not all. Fannie Mae and Freddie Mac's automated underwriting systems sometimes issue appraisal waivers when your property data is already in their systems and there is sufficient comparable sales data in your area. FHA Streamline refinances and VA IRRRL (Interest Rate Reduction Refinance Loan) programs allow refinancing without a new appraisal in many cases, provided you stay within their program requirements. Ask your lender whether your specific scenario might qualify for an appraisal waiver before assuming you'll need one.
Can I roll closing costs into the loan?
Yes, in most cases you can roll closing costs into the new loan balance. This eliminates the need for cash at closing but slightly increases your loan balance and monthly payment. The alternative is a lender credit — the lender covers your closing costs in exchange for a higher interest rate. Both options have pros and cons. Rolling costs into the loan works well if you'll stay long-term; a lender credit works better if you might refinance or sell again within a few years. This calculator assumes closing costs are paid out of pocket. For rolled-in costs, use the No-Closing-Cost Refinance Calculator.
What is the minimum rate drop that makes refinancing worth it?
There is no universal minimum — it depends entirely on your loan balance, closing costs, and how long you plan to stay. A 0.25% rate drop on a $600,000 loan saves significantly more per month than on a $150,000 loan. The right way to evaluate this is to run the actual numbers through this calculator. A refinance makes financial sense when your break-even point is shorter than the time you plan to remain in the home. The general rule of thumb (0.5% to 0.75% minimum) is a starting point, but the math should always make the final decision.
Can I change my loan type with a rate-and-term refinance?
Yes. A rate-and-term refinance can also change your loan type — from FHA to conventional (which can eliminate FHA mortgage insurance premiums), from conventional to FHA or VA (if you qualify), or from an adjustable-rate to a fixed-rate mortgage. Switching from FHA to conventional is particularly valuable if your home's value has risen enough that you now have 20% or more equity, because removing the FHA mortgage insurance premium can save hundreds of dollars per month.
Does a rate-and-term refinance reset my amortization schedule?
Yes. Any refinance — rate-and-term or cash-out — resets your amortization schedule to the beginning of the new loan term. This means your new payments will initially be more interest-heavy than your current payments, even though your total interest may still be lower over the life of the loan. If you have been paying down your loan for several years, resetting to a 30-year term moves you back to the beginning of the amortization curve. This is one important reason to consider matching your remaining term or choosing a shorter term rather than automatically selecting 30 years.
What if I have PMI — does a rate-and-term refinance help?
It can, significantly. If your home value has appreciated since you took out the original loan, a rate-and-term refinance may qualify you for a new loan without PMI — provided your new LTV is 80% or below based on the current appraised value. Removing PMI can save $100 to $300 or more per month depending on your loan balance. The combined benefit of a lower rate plus no PMI can make refinancing extremely attractive even if the rate drop is modest.
How long does a rate-and-term refinance take?
Most rate-and-term refinances close in 30 to 45 days from application. The timeline depends on the lender's workload, how quickly you provide documentation, and whether an appraisal is required. Some lenders advertise faster closings (15 to 21 days) for well-qualified borrowers. After closing, there is typically a three-business-day right of rescission period during which you can cancel. Your first new payment will generally be due about 30 days after your closing date.
