You come into a chunk of cash — a bonus, an inheritance, or leftover proceeds from selling a car or a starter home — and the obvious move is to throw it at the mortgage. But "at the mortgage" can mean two very different things, and they produce very different monthly payments. A mortgage recast keeps your current loan intact, applies your lump sum to principal, and re-amortizes the balance so your payment drops for the remaining term. A refinance replaces the loan entirely — new rate, new term, new closing costs. With the Freddie Mac 30-year fixed rate averaging 6.30% for the week ending April 16, 2026 (down from above 7% two years ago), millions of homeowners with mid-2022 to 2024 mortgages face this exact decision. The right answer depends on your current rate, your remaining term, and how much of that windfall you're willing to tie up in the house.
What a mortgage recast actually does
A recast — sometimes called re-amortization — is a back-office operation at your loan servicer. You send a lump-sum payment against principal, and the servicer recalculates your monthly payment using the new (lower) balance, the same interest rate you have now, and the same remaining term. The loan keeps its original end date. You get a lower monthly payment without a credit check, without an appraisal, and without the thick stack of refinance disclosures.
Fees are small. Most lenders charge somewhere between $150 and $500 for the recast, with Rocket Mortgage publishing a $250 figure as of 2026 per Bankrate's reporting. Processing typically runs 45 to 60 days. Not every loan qualifies — FHA, VA, and USDA loans generally can't be recast, and most servicers restrict it to conventional loans backed by Fannie Mae or Freddie Mac. Most also require a minimum lump sum, usually $5,000 or $10,000, and a handful of on-time payments on the current loan.
What a recast does not do
- It does not change your interest rate. If you locked at 7.25% in 2023, a recast keeps you at 7.25%.
- It does not shorten your remaining term. The loan pays off on the same date it would have.
- It does not reset amortization in your favor. Your payment drops, but the split between principal and interest on each payment stays roughly similar in percentage terms.
How refinancing compares
A refinance is a brand-new loan. The lender pays off your existing mortgage with the proceeds of a new one, and you start fresh — new rate, new term (usually 15 or 30 years), new paperwork, new closing costs. Because today's rates sit meaningfully below the peak-era rates of 2023 and 2024, a refinance can shave the rate, the payment, or both. But it comes with friction: a credit pull, an appraisal, income documentation, and closing costs that typically run 2% to 5% of the loan amount according to Bankrate's 2026 guidance, with a lower real-world average around 0.7% of the loan per LodeStar's closing-cost survey once borrowers shop and negotiate. Either way, you're writing a check (or rolling the costs into the balance) somewhere in the $3,000–$15,000 range for a typical loan.
Refinancing also restarts the amortization clock unless you specifically choose a shorter term. That matters: the first years of a mortgage are interest-heavy, so replacing year 4 of a 30-year loan with year 1 of a new 30-year loan sends you back to the front of the amortization curve. You'll pay less per month, but you may pay more in lifetime interest — unless the rate drop is large enough to offset the reset.
The 2026 math: a side-by-side example
Imagine a homeowner two years into a 30-year mortgage originated in spring 2024 at 7.25%. The starting balance was $400,000; today it's roughly $380,000 with 28 years to go. The monthly principal and interest is $2,645. A $50,000 windfall just landed. Using today's average 30-year rate of 6.30% (Freddie Mac PMMS, week ending April 16, 2026) for any refinance scenarios, here's how four paths compare.
| Strategy | New Monthly P&I | Monthly Savings | Upfront Cost | Remaining Lifetime Interest* |
|---|---|---|---|---|
| Do nothing (keep current loan) | $2,645 | — | $0 | $508,853 |
| Recast: apply $50k, keep 7.25% and 28-yr term | $2,297 | $348 | ~$250 | $441,899 |
| Refi to 30-yr @ 6.30% (keep the $50k) | $2,352 | $293 | ~$9,500 | $466,755 |
| Refi to 28-yr @ 6.30% (keep the $50k, match current payoff date) | $2,410 | $236 | ~$9,500 | $429,712 |
*Interest over the remaining term assuming you make the scheduled payment each month and nothing more. Principal-balance and payment figures computed from standard amortization math at the stated rate and term.
Two things jump out. First, the recast delivers the biggest monthly-payment drop for this homeowner — $348/month vs. $293 for a plain 30-year refi — because applying $50,000 directly to principal is a bigger lever than trimming the rate by 95 basis points. Second, the 28-year refinance wins on total lifetime interest ($429,712 vs. $441,899 for the recast), even though the monthly payment is higher. The refinance gives up more payment relief in exchange for long-run interest savings and keeps the $50,000 in the borrower's pocket.
Break-even tells the story
The recast's $250 fee is recovered in less than one month of payment savings — it's almost trivially a good deal at that fee level. The refinance's ~$9,500 in closing costs takes about 32 months (just under three years) of the $293 monthly savings to recoup. If the homeowner plans to sell, move, or pay off the loan before that three-year mark, the refi loses on pure break-even. A recast, by contrast, essentially always breaks even within the first billing cycle.
When a recast makes more sense
Pick a recast when the math favors stability over rate-hunting:
- Your current rate is already competitive. If you locked at 3.25% in 2021, no 2026 rate will beat that. Throwing cash at principal and re-amortizing is the only way to turn the windfall into a lower payment without giving up the great rate.
- You don't want to restart the clock. Four years into a 30-year loan, a refinance to a new 30-year loan means 34 total years of paying the mortgage. A recast keeps your original end date.
- You want the lowest-effort path. A recast is a form, a fee, and a re-amortization. A refinance is an application, an appraisal, tax returns, pay stubs, title work, and a closing. For busy households or self-employed borrowers with paperwork-heavy income documentation, the friction difference is real.
- Your credit or income picture has softened. Recasts do not require requalification. If you've changed jobs, started a business, or watched your credit score dip, a recast sidesteps the underwriter entirely.
When a refinance wins
Lean toward a refinance when the rate gap is wide, your plans are long, or the loan is FHA/VA:
- Your current rate is 1–2+ percentage points above today's average. A homeowner sitting on a 7.5% loan with 6.30% rates available has a very different calculation than someone at 6.5%. The rule of thumb that a 75-basis-point drop justifies the closing costs still broadly applies in 2026, adjusted for how long you plan to stay.
- You plan to stay in the home past the break-even point. Sub-three-year break-evens on a typical refi make sense when you expect to own the home for five-plus years. Shorter horizons tilt toward a recast or doing nothing.
- You have an FHA, VA, or USDA loan. Most servicers don't offer recasts on government-backed loans. Refinancing — especially a streamline refinance (FHA Streamline or VA IRRRL) — is the main way to cut the payment.
- You want to shorten the term. If your real goal is paying off the house faster at a lower rate, refinancing from a 30-year to a 15- or 20-year loan is the cleanest path.
- You want to pull cash out. Only a cash-out refinance unlocks equity as cash. A recast moves money into the mortgage, not out of it.
The hybrid move: refinance, then recast
For borrowers with both a high current rate and a large lump sum, the strongest play is often to refinance first and recast later. The sequence looks like this. You refinance to today's lower rate on the full balance. A few months after the new loan settles, you send a lump-sum payment to the new servicer and request a recast. The refinance captures the rate savings on every dollar of balance, and the recast translates your lump sum into a smaller monthly payment on the new loan. This two-step protects against an overlooked pitfall: if you applied the lump sum first and then tried to refinance, the smaller new loan amount would still carry the same fixed closing costs, so the cost-per-benefit of the refi gets worse.

Recast eligibility checklist
Before you plan around a recast, confirm every one of these with your servicer in writing. Rules vary between lenders.
- Loan type: conventional loan serviced under Fannie Mae or Freddie Mac guidelines. FHA, VA, USDA, and jumbo portfolio loans are frequently ineligible.
- Minimum lump sum: typically $5,000 or $10,000, but some lenders require a minimum of 10% of the current balance.
- Payment history: usually at least two to six months of on-time payments on the current loan.
- Recast fee: commonly $150–$500. Get the exact number before you send the lump sum, since sending the cash first and then discovering the fee is a bad sequence.
- How the lump sum applies: must be treated as "principal-only" before the recast takes effect. If it lands in escrow, the math won't work. The Consumer Financial Protection Bureau has clear guidance on flagging a payment as principal-only.
- Turnaround: 45–60 days is typical. Confirm the first billing cycle that reflects the new payment so you don't accidentally short your autopay.
How to request a recast, step by step
- Call your servicer (not your original lender if the loan was sold) and ask for "principal reduction with re-amortization" or "mortgage recasting." Get the policy, fee, minimum, and timeline in writing.
- Confirm your loan is eligible and that you've cleared the payment-history requirement. Ask whether there's a seasoning window from the most recent recast, if you've done one before.
- Request the recast package or portal form. Most servicers send a simple authorization form plus wire/ACH instructions.
- Send the lump sum clearly marked as "principal only." Reference your loan number on the transfer. Keep the confirmation.
- Sign and return the recast agreement along with the fee. Some lenders net the fee out of the lump sum; others bill separately.
- Verify on the next statement. The balance should drop and the minimum payment field should update. If either one didn't change, call immediately — the lump sum may have posted to escrow or the recast may still be pending.

Frequently Asked Questions
Will my interest rate change when I recast?
No. A recast keeps your existing note rate. If you're on a 7.25% fixed-rate loan, you'll be on a 7.25% fixed-rate loan after the recast — just with a smaller balance and a smaller monthly payment. That's the main reason borrowers with old low-rate loans prefer a recast to a refinance.
Can I recast after making extra monthly principal payments?
Yes. Extra payments reduce principal but do not automatically re-amortize the loan. A recast is what converts the lower balance into a lower required monthly payment. You can recast a few months after making a large prepayment if you want to lock in the lower minimum.
How much does a mortgage recast cost?
Typical recast fees range from $150 to $500. Specific servicers publish specific numbers — Rocket Mortgage, for example, lists a $250 recast fee per Bankrate's 2026 reporting. That's at least an order of magnitude less than the $3,000–$15,000 you might pay to refinance a similar loan.
Can you recast an FHA or VA loan?
Generally no. FHA, VA, and USDA loans are typically not eligible for recasting under standard servicer policies. The usual workaround is an FHA Streamline or VA IRRRL refinance, which waives some documentation and lets you capture a lower rate without a full underwrite.
Does recasting hurt my credit score?
A recast does not involve a credit pull, so there's no inquiry impact. Because the loan continues under its original terms, it also doesn't create a new tradeline or close the old one — your length-of-credit history is preserved.
What's the minimum lump sum to trigger a recast?
Most lenders require at least $5,000 or $10,000, or 10% of the current balance, whichever is greater. Sending less than the minimum will still reduce your balance as an extra principal payment, but the servicer will not re-amortize the monthly payment.
Is a recast ever a bad idea?
Potentially, yes. Tying up a large chunk of cash in home equity trades liquidity for a modest monthly-payment drop. If that same $50,000 could earn 4%+ in a high-yield savings account or Treasury while your mortgage sits at, say, 4% or below, the opportunity cost of the recast can exceed the interest savings. Recasts are most compelling when your mortgage rate is meaningfully above risk-free returns — which describes most 2023–2024 originations in today's 2026 environment.
Can I do a recast more than once?
Many servicers allow multiple recasts over the life of a loan, but some impose a seasoning window (often 12 months) between recasts or cap the number allowed. Ask before you plan a strategy around annual recasts.
