A mortgage recast lets you drop a lump sum onto your principal and re-amortize your loan for a lower monthly payment — same interest rate, no new appraisal, and a fee of just $150-$500. Here's exactly how recasting works in 2026, who it's right for, and how it stacks up against refinancing.
Here's a scenario that plays out all the time. You bought your home a couple of years ago, locked in a decent interest rate, and then a chunk of cash landed in your lap — a year-end bonus, an inheritance, the sale of an old property, maybe some vested stock. You'd love to lower your monthly mortgage payment, but every loan officer you talk to wants to refinance you into today's rates, which are higher than what you've already got. Refinancing would actually make your situation worse.
That's exactly the situation a mortgage recast was built for. It's one of the most overlooked tools in homeownership, partly because lenders don't make much money on it, so nobody's running ads about it. But for the right borrower, recasting can knock hundreds of dollars off your monthly payment for a one-time fee that's usually somewhere between $150 and $500. No new loan. No closing costs. No credit pull. Same rate you already love.
The short version: you make a big lump-sum payment toward your principal, your lender re-runs the math on your remaining balance, and your monthly payment shrinks for the rest of the loan term. Your interest rate and your payoff date stay exactly the same.
In this guide we'll walk through how a recast actually works, run real dollar examples, compare it head-to-head with refinancing in a table, and help you figure out whether you're the kind of borrower who should be doing this. If you want to play with the numbers as you read, keep our mortgage calculator open in another tab.
What Is a Mortgage Recast, Exactly?
A mortgage recast — sometimes called a "re-amortization" — is when you pay a large lump sum toward your loan's principal balance, and your lender then recalculates your monthly payment based on the new, lower balance. Crucially, three things do not change:
- Your interest rate stays the same. If you have a 4.25% loan, you keep your 4.25% loan. This is the whole point.
- Your loan term stays the same. If you had 26 years left before the recast, you'll still have 26 years left after. You're not extending or shortening the payoff date.
- Your loan itself stays the same. No new application, no new note, no new title work. It's the same mortgage with a smaller balance.
What does change is your monthly principal-and-interest payment. Because the loan is now being amortized over the same number of remaining months but starting from a smaller balance, each payment drops. Think of it as squeezing a smaller balloon payment schedule into the same timeline.
This is fundamentally different from just making an extra principal payment on its own. When you throw extra money at your principal without recasting, your monthly payment stays the same — you just pay the loan off earlier. A recast is the opposite trade: you keep the same payoff date but lower the payment. You're trading time savings for monthly cash-flow relief.
How re-amortization works under the hood
Mortgages amortize, which means each monthly payment is split between interest and principal, and that split shifts over time. Early in the loan, most of your payment goes to interest. Your lender uses three inputs to calculate your payment: the loan balance, the interest rate, and the number of months remaining. A recast changes only the first input — the balance — and then re-solves the equation. Same rate, same months, smaller balance, smaller payment. That's all there is to it mathematically.
Recast vs Refinance: The Comparison That Actually Matters
This is the decision most people are really trying to make, so let's lay it out clearly. Refinancing replaces your old loan with a brand-new one, which means you can change your rate and term but you'll pay for the privilege. A recast keeps everything about your loan intact except the balance and the payment. Here's the side-by-side:
| Feature |
Mortgage Recast |
Refinance |
| Interest rate |
Stays the same (unchanged) |
Changes to current market rate (could be higher or lower) |
| Typical cost |
$150-$500 flat fee |
$3,000-$6,000+ in closing costs (roughly 2%-5% of loan) |
| Credit check / underwriting |
None required |
Full credit check and income/asset underwriting |
| New appraisal |
Not required |
Usually required ($400-$700) |
| Loan term |
Unchanged (same payoff date) |
Resets — often back to 30 years unless you choose otherwise |
| Lowers monthly payment? |
Yes, via lump-sum principal reduction |
Yes, via lower rate and/or longer term |
| Requires a lump sum? |
Yes — that's the mechanism |
No lump sum needed |
| Time to complete |
A few weeks, minimal paperwork |
30-45 days, heavy paperwork |
| Cash-out option |
No |
Yes (cash-out refinance) |
The simplest way to think about it: refinancing is about your rate, recasting is about your balance. If today's rates are meaningfully lower than your current rate, refinancing usually wins because the rate savings compound over the whole loan. If today's rates are higher than your current rate — which has been the reality for many homeowners who bought during the low-rate years — then refinancing would force you to give up your great rate, and a recast becomes the smarter move.
If you're not sure which camp you fall into, run both scenarios. Our refinance calculator will show you the break-even point on a refi, and you can compare that against the no-rate-change math of a recast. For a deeper dive on the refinancing side specifically, our complete refinancing guide covers when it makes sense and how to shop lenders.
A Real Dollar Example: What $50,000 Does to Your Payment
Numbers make this concrete, so let's build a realistic 2026 example. Say you have a conventional 30-year mortgage you took out a few years ago:
- Original loan amount: $400,000
- Interest rate: 4.00% (a rate you'd never want to give up in today's market)
- Current remaining balance: $370,000
- Remaining term: 26 years (312 months)
- Current principal-and-interest payment: roughly $1,910 per month
Now you receive $50,000 — say, from an inheritance — and you apply it as a recast. Your new balance becomes $320,000, re-amortized over the same 26 remaining years at the same 4.00% rate. Your new principal-and-interest payment drops to roughly $1,652 per month. That's about $258 less every month, or just over $3,000 a year back in your pocket, for the rest of the loan.
Here's how a few different lump-sum amounts might shake out on that same $370,000 balance at 4.00% with 26 years left (figures are rounded estimates for illustration):
| Lump Sum Applied |
New Balance |
New Monthly P&I (approx.) |
Monthly Savings (approx.) |
| $25,000 |
$345,000 |
$1,781 |
$129 |
| $50,000 |
$320,000 |
$1,652 |
$258 |
| $75,000 |
$295,000 |
$1,523 |
$387 |
| $100,000 |
$270,000 |
$1,394 |
$516 |
Notice the savings scale almost linearly with the lump sum — roughly $5 of monthly payment relief for every $1,000 you put in, at this rate and term. That ratio shifts with your rate and remaining years, so plug your own numbers into the mortgage calculator before committing. And remember: you're also saving a meaningful chunk of total interest over the life of the loan, because there's less principal accruing interest from day one.
Who Should Consider a Mortgage Recast?
A recast is a great fit for a specific kind of borrower. You're probably a strong candidate if most of these describe you:
- You have a low interest rate you don't want to lose. If your current rate is below today's market rates, refinancing would push your rate up. A recast lets you lower your payment while keeping your golden rate. This is the single most important factor.
- You just came into a meaningful chunk of cash. An inheritance, a sizable bonus, proceeds from selling another property, a business windfall, or vested equity compensation. The recast turns that one-time cash into permanent monthly breathing room.
- You want lower monthly payments, not a faster payoff. If your goal is improving cash flow — freeing up money for other goals, reducing financial stress, or qualifying for something else — a recast directly lowers the payment.
- You already have a loan in good standing. Most servicers want your payments to be current before they'll recast.
- You'd rather avoid paperwork and underwriting. No income docs, no credit pull, no appraisal — useful if your income is variable (self-employed) or your credit has dipped since you got the loan.
One common and underrated scenario: you bought a new home before selling your old one, took a larger mortgage than you wanted, and then your old house sold. Instead of being stuck with that big payment, you recast the new loan with the sale proceeds and bring the payment down to where you actually wanted it. Some lenders even offer this as a "delayed financing" or new-purchase recast specifically for this situation.
Who Should NOT Recast (or Should at Least Think Twice)?
Recasting isn't for everyone. Here's when a different move probably serves you better:
- Today's rates are well below your current rate. If you could refinance into a meaningfully lower rate, that almost always beats a recast over the life of the loan, even with closing costs. Run the numbers in our refinance calculator first.
- You don't have a lump sum to spare. A recast requires cash you're willing to lock into your home. No lump sum, no recast.
- That cash could do more elsewhere. If you're carrying credit card debt at 22% or a car loan at 9%, paying those down beats reducing a 4% mortgage payment. The same logic can apply to investing if you're comfortable with market risk and have a long horizon.
- You might need that cash for an emergency. Once it's in your home equity, it's not liquid. You'd have to borrow it back out via a home equity loan or HELOC — which means new costs and possibly a higher rate. Don't recast away your emergency fund.
- You have an FHA, VA, or USDA loan. These government-backed loans generally can't be recast (more on that next). For those, refinancing — including a streamline refi — is usually the path to a lower payment.
If you'd rather keep your cash liquid but still tap your equity, comparing a cash-out refinance vs a HELOC is worth your time — that's a different strategy that pulls money out rather than putting it in.
Which Loans Are Eligible for a Recast?
This trips a lot of people up, so let's be precise. Eligibility depends heavily on your loan type:
- Conventional loans (Fannie Mae / Freddie Mac): usually eligible. Most conventional fixed-rate and adjustable-rate mortgages can be recast, as long as your servicer offers it. This is the sweet spot.
- Jumbo loans: sometimes eligible. Many portfolio lenders allow recasting on jumbo loans, but policies vary widely. Ask your servicer directly.
- FHA loans: generally NOT eligible. FHA loans don't allow recasting. To lower an FHA payment you'd typically use an FHA streamline refinance.
- VA loans: generally NOT eligible. VA loans can't be recast either; an IRRRL (Interest Rate Reduction Refinance Loan) is the VA equivalent for lowering payments.
- USDA loans: generally NOT eligible. USDA loans follow similar restrictions and rely on refinancing instead.
Even within conventional loans, individual servicers set their own rules — some don't offer recasting at all, and a handful will only do it once over the life of the loan. The only way to know for certain is to call your loan servicer (the company you send your payment to, not necessarily the original lender) and ask: "Do you offer principal-reduction recasting on my loan, and what are the requirements?"
Fees, Minimum Deposits, and the Fine Print
Recasting is cheap compared to refinancing, but it's not free, and there are a few thresholds to know about:
- Recast fee: typically a flat $150-$500, depending on the servicer. Some cap it, some charge a small percentage. Either way it's a fraction of refinance closing costs.
- Minimum lump sum: many lenders require a minimum principal reduction to bother recalculating — commonly around $5,000 to $10,000, though some set it higher. A few base it on a percentage of your balance.
- New-balance threshold: some servicers require the recast to reduce your payment by a minimum amount or your balance by a minimum percentage.
- Loan-in-good-standing requirement: you generally need to be current on payments, and sometimes you need a clean payment history for the prior 12 months.
- Waiting period: some lenders won't recast within the first few months of a loan or within a set window after the last recast.
One nice detail: because there's no underwriting, your escrow account (taxes and insurance) usually isn't disturbed by the recast itself — only your principal-and-interest portion changes. Your total payment will reflect the lower P&I plus whatever your escrow currently collects.
How to Recast Your Mortgage: Step by Step
- Confirm your loan is eligible. Call your servicer and verify that recasting is available on your specific loan type and that you meet their minimum lump-sum and payment-history requirements.
- Run the numbers first. Before you part with the cash, model the new payment. Compare the recast result against a refinance scenario so you know you're choosing the better path. Our mortgage calculator and refinance calculator together give you the full picture.
- Request the recast in writing. Ask your servicer for their recast (re-amortization) request form and the exact fee. Get the minimum deposit and any deadlines in writing.
- Make the lump-sum principal payment. Send the funds clearly designated as a "principal-only" payment toward the recast — not a regular payment, or it may be applied incorrectly.
- Pay the recast fee and sign the paperwork. The servicer recalculates your amortization and sends you a new payment schedule.
- Verify your new payment and statement. Once it's processed (usually within a billing cycle or two), confirm your statement shows the lower payment, the same rate, and the same payoff date.
Recast vs Other Ways to Lower Your Payment
A recast is one tool among several. Depending on your situation, one of these might fit better:

Frequently Asked Questions
Does a mortgage recast lower my interest rate?
No. A recast never changes your interest rate — that's actually its biggest advantage if you already have a low rate. It lowers your monthly payment purely by reducing the principal balance the payment is calculated from. If your goal is a lower rate, you need a refinance, not a recast.
Does recasting require a credit check or appraisal?
No. Because you're not taking out a new loan, there's no underwriting, no credit pull, and no new appraisal. That makes recasting attractive if your credit has slipped, your income is hard to document, or your home's value has dipped since you bought it.
How much does it cost to recast a mortgage?
Most servicers charge a flat fee in the $150-$500 range. There may also be a minimum lump-sum requirement (often around $5,000-$10,000). Compared with refinance closing costs of several thousand dollars, recasting is dramatically cheaper.
Will recasting shorten my loan term?
No. Your payoff date stays the same. A recast re-amortizes your smaller balance over the same number of remaining months, which lowers each payment. If you want to pay the loan off faster instead, just make extra principal payments without recasting — that keeps your payment the same but shortens the term.
Can I recast an FHA, VA, or USDA loan?
Generally no. Recasting is mainly available on conventional loans (and some jumbo loans). FHA, VA, and USDA loans typically don't allow recasting; to lower the payment on those, you'd look at a streamline refinance or, for VA, an IRRRL.
Is it better to recast or just make extra principal payments?
It depends on your goal. Extra principal payments (without a recast) keep your monthly payment the same and pay the loan off earlier — best if you want to be debt-free sooner. A recast lowers your monthly payment but keeps the original payoff date — best if you want improved monthly cash flow. Same money, two different outcomes.
How often can I recast my mortgage?
That's set by your servicer. Some allow multiple recasts over the life of the loan, while others limit you to one. There may also be a waiting period after the previous recast or after loan origination. Always confirm the policy with your servicer before planning around it.
Can I get the lump sum back after I recast?
Not directly — once the cash is applied to principal, it becomes home equity, not liquid money. To access it again you'd need to borrow against your equity through a home equity loan, a HELOC, or a cash-out refinance, each of which has its own costs. That's why you should never recast money you might need for an emergency.
The Bottom Line
A mortgage recast is a low-cost, low-hassle way to turn a one-time pile of cash into a permanently lower monthly payment — without touching your interest rate, resetting your term, or going through underwriting. For homeowners sitting on a great rate who've come into some money, it's often a smarter move than refinancing into today's higher rates.
The decision really comes down to one question: do you want to keep your current rate, or change it? If you want to keep it, recasting is your tool. If today's rates are lower and you'd happily swap, look at a refinance instead. Run both scenarios with hard numbers, confirm your loan is eligible with your servicer, and you'll know exactly which path puts the most money back in your pocket each month.
