A mortgage recast is when you pay a large lump sum toward your loan’s principal, and your lender then recalculates a lower monthly payment over your same remaining term and same interest rate. There is no new loan, no new credit check, and no new closing process. Your balance drops, your payment drops with it, and everything else about the loan stays the same.
A mortgage recast keeps your existing loan and interest rate, but lowers your monthly payment after you pay down a chunk of your principal balance. Your lender re-amortizes, or recalculates, the remaining payments over your remaining term using the new, smaller balance. It is not a refinance, so there is usually no new credit pull, no new appraisal, and no new closing costs, though a small recast fee is common. Not every loan qualifies, and many government-backed loans commonly do not offer recasting at all.
What a Mortgage Recast Actually Is
Think of your mortgage as a schedule of fixed payments that slowly pays off a starting balance over many years. That schedule is called amortization, and it assumes your balance shrinks at a steady, predictable pace.
A recast interrupts that steady pace on purpose. You hand your lender a large lump-sum payment that goes straight toward your principal balance. Your lender then rebuilds the amortization schedule from that lower balance, spreading the remaining payments across whatever time is left on your loan.
The interest rate does not change. The loan term does not change. Only the size of your remaining balance changes, and because a smaller balance needs smaller payments to pay it off on the same schedule, your monthly payment drops.
This makes a recast attractive to borrowers who want lower monthly costs without restarting their loan clock. Your payoff date does not move, and your loan does not reset to a fresh 30-year schedule. It simply becomes cheaper to carry each month.
How Recasting Works, Step by Step
The process is more paperwork than procedure, and it is far simpler than most other mortgage changes you could make.
First, you make a lump-sum payment toward principal, separate from your regular monthly payment. This might come from a bonus, an inheritance, the sale of another property, or simple savings. Lenders commonly set a minimum amount required to recast.
Next, you contact your loan servicer and formally request a recast. Some lenders charge a small administrative fee, often a few hundred dollars, though this varies widely by lender.
Finally, your lender recalculates your payment using your new, lower balance, your existing interest rate, and your remaining term. The new, lower payment typically takes effect within a billing cycle or two.
Your escrow account for taxes and insurance is not affected by a recast, since escrow is calculated separately from your principal and interest payment. Some lenders ask you to submit a written request or a simple form rather than a phone call. Processing times vary, but most lenders complete a recast within a few weeks of receiving your lump sum.
Recasting vs Refinancing: What Is the Difference?
People often confuse recasting with refinancing, but they solve different problems in very different ways. Refinancing replaces your loan entirely with a brand new one, usually to chase a lower interest rate or change your loan term.
A refinance involves a new application, a new credit check, a new appraisal in most cases, and a fresh round of closing costs. A recast keeps your original loan in place and simply lowers the payment on it.
| Attribute | Recast | Refinance |
|---|---|---|
| New loan | No, same loan continues | Yes, old loan is paid off and replaced |
| Interest rate | Stays exactly the same | Usually changes to a new market rate |
| Credit check | Usually not required | Almost always required |
| Closing costs | Small fee, often a few hundred dollars | Often thousands of dollars in fees |
| Requires a lump sum | Yes, a minimum principal payment | No lump sum required |
In short, a recast is a small, quick adjustment to an existing loan. A refinance is a bigger, slower decision that swaps one loan for another.
What You Need to Qualify for a Recast
Not everyone can recast, and requirements vary by lender, so always confirm details directly with your loan servicer.
A minimum lump-sum amount is commonly required, and lenders set their own thresholds. Some lenders also charge a small processing fee to complete a recast.
Most importantly, your lender has to actually offer recasting as an option, and not every loan program allows it. Many government-backed loans, such as certain FHA and VA loans, commonly do not permit recasting, while many conventional loans do.
Some lenders also require your loan to be current on payments before they will approve a recast request. Investment properties and second homes may face different rules than a primary residence, depending on the lender. It is worth asking your servicer whether your specific loan type qualifies before you plan around a recast.
A Simple Example With Made-Up Numbers
Say you have a loan with a remaining balance of 300,000 dollars, a fixed rate, and 25 years left on the term. Your current monthly principal and interest payment might sit around 1,900 dollars.
Now suppose you receive a 50,000 dollar bonus and decide to put it toward your mortgage as a recast lump sum. Your new balance becomes 250,000 dollars.
Your lender then re-amortizes that 250,000 dollar balance over the same 25 remaining years, at the same rate. Your new monthly payment might fall to roughly 1,590 dollars, a meaningful drop without touching your rate or restarting your loan term.
These numbers are illustrative only. Your real balance, rate, and remaining term will shape your own result, so use the Mortgage Amortization Calculator to see how a lump sum toward your own loan could change your monthly payment.
How a Recast Affects Your Total Interest
Paying down principal early does more than lower your monthly bill. It also shrinks the total interest you pay over the life of the loan, because interest is calculated on your remaining balance each month.
A smaller balance means less interest builds up with every payment cycle. Over many years, that difference can add up to thousands of dollars in savings.
The exact savings depend on your rate, your balance, and how many years remain on your loan. Borrowers who recast early in their loan term tend to see larger interest savings than those who recast near the end.
Why Someone Might Choose a Recast Over a Refinance
Recasting appeals to people who already have a low interest rate they do not want to give up. Refinancing into a new loan means accepting whatever rate is available today, which may be higher than your current rate.
Recasting is also simpler and cheaper. There is no lengthy underwriting process, no new closing disclosures, and no appraisal fee to pay. For many borrowers, that simplicity alone is the deciding factor.
It also suits borrowers who came into a windfall but do not need to shorten their loan term or change lenders. They just want a smaller, more comfortable monthly payment going forward.
A recast can also make sense when mortgage rates have risen since you took out your loan, since refinancing in that situation would likely raise your rate instead of lowering it. Keeping the original rate while shrinking the balance often produces real monthly savings without that risk.
Which Loans Allow Recasting?
Recasting availability depends heavily on the specific loan type and the specific lender, so this section only offers a general pattern.
Conventional loans commonly allow recasting, since many conventional lenders offer it as a standard option. Jumbo loans often allow it too, depending on the lender’s own policies.
Many government-backed loan programs, including many FHA, VA, and USDA loans, commonly do not offer recasting at all. If your loan falls into one of these categories, ask your servicer directly whether any exception exists, since policies can differ by lender and by year.
Loan servicers that hold a mortgage in their own portfolio, rather than selling it to an investor, sometimes have more flexibility to offer a recast. Some jumbo loan servicers also set higher minimum lump-sum amounts than conventional lenders require. Always check your specific loan documents or call your servicer to confirm what your loan allows.

FAQs About Mortgage Recasting
What Is a Mortgage Recast in Simple Terms?
A mortgage recast is when you pay a lump sum toward your loan’s principal, and your lender lowers your monthly payment to match the smaller balance. Your interest rate and remaining term stay exactly the same. It is a way to lower payments without replacing your loan.
How Is a Recast Different From a Refinance?
A recast keeps your existing loan and rate, while a refinance replaces your loan with a brand new one, often at a new rate. Refinancing usually requires a credit check, an appraisal, and closing costs. Recasting typically needs only a lump sum and a small processing fee.
How Much Money Do I Need to Recast My Mortgage?
Lenders commonly set their own minimum lump-sum amount required to recast, and this varies from lender to lender. There is no single number that applies to every loan. Contact your loan servicer directly to confirm the minimum amount your specific loan requires.
Does Recasting Change My Interest Rate or Loan Term?
No. Recasting keeps your original interest rate and your original remaining term in place. Only your monthly payment changes, because it is recalculated using your new, smaller balance. This is one of the biggest differences between recasting and refinancing.
Do FHA and VA Loans Allow Recasting?
Many FHA, VA, and USDA loans commonly do not allow recasting, since it is generally a feature offered on conventional and some jumbo loans. Rules can vary by lender and by year, so always confirm directly with your loan servicer about your specific loan program.
Is There a Fee to Recast a Mortgage?
Many lenders charge a small administrative fee to process a recast, often a few hundred dollars, though this varies by lender. This fee is typically much smaller than the closing costs involved in a full refinance. Ask your servicer for their exact fee before requesting a recast.
When Does a Recast Make More Sense Than a Refinance?
Recasting often makes more sense when you already have a low interest rate you want to keep and you simply want a lower monthly payment. It also suits borrowers who want a simpler, cheaper process without new underwriting. A refinance may fit better if you specifically want a new rate or a different loan term.
