By Muhammad Adeel, Founder · Published 2026-10-09
A mortgage recast lets you cut your monthly payment with a lump sum and a small flat fee, no new loan required. Here is the math, the qualification rules, and when recasting beats refinancing.
What a Recast Actually Does
A mortgage recast, also called re-amortization, works like this: you make a large lump-sum payment toward your principal, and your lender recalculates your monthly payment based on the new, lower balance. Your interest rate stays the same. Your remaining term stays the same. Only the payment drops.
The cost is a flat fee, typically $150 to $500 depending on the lender. Compare that with a refinance, where closing costs run 2% to 6% of the loan amount. On a $400,000 loan, refinancing costs $8,000 to $24,000. Recasting costs less than a nice dinner out.
There is also no credit check, no appraisal, and no income verification. The lender already holds your loan, so the paperwork is minimal. Most recasts close in 30 to 60 days, and some lenders move faster.
The Math: $50,000 In, $333 a Month Out
Here is a concrete example. You owe $400,000 at 7.0% with 25 years (300 payments) remaining. Your principal and interest payment is about $2,827 a month. You come into $50,000, perhaps a bonus, an inheritance, or proceeds from selling another asset, and you put the whole amount toward the loan.
After a recast, your balance is $350,000, still at 7.0%, still with 25 years left. Your new payment is about $2,474 a month. That is roughly $333 less every month, and over the remaining term you save more than $87,000 in interest compared with doing nothing.
Now here is the subtle part. If you made that same $50,000 as a plain extra principal payment (a curtailment) without recasting, you would save the identical $87,000 in interest, but your required monthly payment would stay at $2,827. You would just finish paying years early. A recast buys you monthly cash flow. A curtailment buys you a shorter loan. Same interest saved, completely different benefit. Choose based on whether you need breathing room now or freedom sooner.
Recast vs Refinance: An Honest Comparison
Refinancing replaces your loan with a new one. That makes sense when market rates have fallen at least a full percentage point below your current rate, when you want to change your term (say from 30 years to 15), or when you need cash out. In 2026, with rates near 7.5%, very few existing borrowers meet the rate-drop test.
Recasting keeps your loan and just reshapes the payment. It wins when your current rate is already below market rates, which describes millions of borrowers holding 3% to 5% loans from 2020 through 2022. Why would you refinance out of a 3% rate into a 7.5% rate? You would not. But if you have a lump sum sitting idle, a recast lets you put it to work without touching that precious rate.
Run both scenarios in our free US mortgage calculator. Model the recast as your current balance minus the lump sum at your current rate and term, and model the refinance as a new loan at today's rate with closing costs added. The comparison usually ends the debate in about two minutes.
Who Qualifies (and Who Does Not)
Recasts are generally available on conventional loans backed by Fannie Mae and Freddie Mac, which covers the majority of US mortgages. FHA and VA loans usually cannot be recast, so government-loan borrowers are mostly out of luck here.
Lenders set a minimum lump sum, commonly $5,000 to $10,000. Some require that you have made a minimum number of on-time payments first, often 12 months. And you cannot recast during an active forbearance or if the loan is delinquent.
One more restriction to know: most lenders allow only one recast per loan, or one every 12 months. So do not recast with $10,000 in January and then wish you had waited for the $40,000 bonus arriving in June. Time the lump sum deliberately.
The Decision Rule
Recast when your current rate is below today's market rate and you have a lump sum of at least $5,000 to $10,000 that is not needed for your emergency fund. This is the classic 2020-era borrower situation: a 3% rate, a growing savings balance, and no good reason to refinance.
Refinance when market rates sit at least one full point below your rate, or when you need something a recast cannot give you: a shorter term, cash out, or removing mortgage insurance. Do the break-even math on closing costs every time. A refinance that saves $200 a month but costs $12,000 takes five years to pay for itself.
Do neither when the lump sum would drain your emergency reserves. Six months of expenses in liquid savings comes before any mortgage optimization. Practical next step: call your loan servicer (not your original lender, the company you send payments to) and ask two questions. What is your recast fee, and what is the minimum lump sum? Then model the new payment in our free US mortgage calculator and compare it against your current budget before you move the money.

How much does a mortgage recast cost?
Most lenders charge a flat fee between $150 and $500. There are no appraisal, title, or origination fees because no new loan is created. Always confirm the exact fee with your servicer before proceeding.
Does a recast change my interest rate or loan term?
No. Your rate and remaining term stay exactly the same. Only the monthly payment is recalculated downward based on the reduced balance. If you want a different rate or term, you need a refinance.
Can I recast an FHA or VA loan?
Usually not. Recasts are generally limited to conventional loans backed by Fannie Mae or Freddie Mac. FHA and VA servicing guidelines do not typically allow re-amortization, so check with your servicer, but expect a no.
Is a recast better than just making a large extra payment?
They save the identical amount of interest. The difference is cash flow: a recast lowers your required monthly payment, while a plain extra payment leaves the payment unchanged and shortens the loan instead. Pick the benefit you actually need.
How long does a recast take?
Typically 30 to 60 days from the lump-sum payment to the new payment schedule taking effect. There is no underwriting, so the timeline is mostly administrative processing by your servicer.
When should I refinance instead of recasting?
Refinance when market rates are at least one percentage point below your current rate, when you want to change your loan term, or when you need cash out. A recast cannot change your rate, term, or loan type.
