A mortgage recast and a refinance can both lower your monthly payment, but they work in different ways.
A recast keeps your current mortgage. You make a large payment toward the principal balance, then your servicer recalculates the monthly payment using the lower balance, existing interest rate and remaining loan term. Fannie Mae describes this as re-amortizing the mortgage after a substantial principal curtailment.
A refinance pays off your current mortgage and replaces it with a new one. That new loan can have a different interest rate, term, payment, borrower structure or loan purpose. Because it is a new mortgage, a refinance involves underwriting, lender approval and closing disclosures. The CFPB says lenders must provide a Closing Disclosure three business days before a scheduled mortgage closing.
The short version: choose a recast when you like your current loan and only want a lower payment after putting cash toward the balance. Consider refinancing when the loan itself needs to change.

What Is A Mortgage Recast?
A mortgage recast, also called a re-amortization, recalculates your monthly payment after you make a large payment toward your loan principal.
Here is the practical version. Suppose you receive money from selling another property, a bonus or an inheritance. You put part of that money toward your mortgage principal. Instead of keeping the same required payment and simply paying the loan off faster, a recast spreads the smaller remaining balance over the remaining loan term.
The result is a lower required monthly principal and interest payment. Your interest rate does not change. Your mortgage is not replaced. Your remaining term generally stays in place.
Fannie Mae’s servicing guide says a servicer may reduce the principal and interest payment after a substantial principal curtailment by re-amortizing the current unpaid principal balance using the current interest rate and remaining loan term.
What Is A Refinance?
A refinance replaces your existing mortgage with a new loan. The new loan pays off the old one, then you make payments under the new loan terms.
That structure gives refinancing more reach than a recast. You may be able to lower your rate, shorten or lengthen the term, move from an adjustable-rate mortgage to a fixed-rate mortgage, remove a borrower or use home equity through a cash-out refinance. The tradeoff is that you have to qualify for the new mortgage.
A refinance is also a closing event. The lender must provide mortgage disclosures, and the CFPB says the Closing Disclosure gives final details about the loan terms and closing costs. Borrowers receive it at least three business days before the scheduled closing.
How A Mortgage Recast Works
A recast starts with your current servicer. You ask whether your loan is eligible, how large the principal payment must be and what fee or paperwork applies.
If the servicer approves the request, you make the required principal payment. The servicer applies that money to the loan balance, then recalculates the principal and interest payment over the remaining term.
A recast does not erase interest already charged. It also does not change your note rate. If your current mortgage rate is 3.25%, the recast keeps that rate. If your current mortgage rate is 7%, the recast keeps that rate too.
The value is payment relief. The cost is liquidity. Once you put the cash into home equity, you no longer have that money available for savings, repairs or other expenses unless you borrow against the home later.
How A Refinance Works
A refinance starts with a new loan application. The lender reviews your credit, income, debt, property value and loan purpose.
If the refinance is approved, the new loan pays off the existing mortgage. The old loan closes out, and the new mortgage takes its place. Your payment then follows the new interest rate, term and loan balance.
Closing costs are the key friction point. A lower rate does not automatically mean a refinance is worth it. The monthly savings need to outweigh the cost of replacing the loan, especially if you plan to sell the home before reaching the break-even point.
When A Mortgage Recast Makes Sense
A recast makes the most sense when you already have a loan worth keeping.
The clearest example is a homeowner with a low fixed rate who receives a large amount of cash. Refinancing that loan into today’s market could raise the rate. A recast lets the homeowner lower the payment while preserving the original rate.
A recast can also fit after buying a new home before selling the old one. Once the previous home sells, the homeowner applies sale proceeds to the new mortgage and asks the servicer to recast the payment. That can turn a temporarily high payment into a lower long-term payment without replacing the loan.
The main limitation is access. Not every loan can be recast, and the rules come from the loan investor and servicer. Some government-backed loans and certain loan types are more restrictive. Ask your servicer before making a large principal payment if your goal is a lower required monthly payment.
When A Refinance Makes Sense
Refinancing makes more sense when the problem is the loan, not just the payment.
If current rates are meaningfully lower than your existing rate, a refinance can reduce interest costs. If your adjustable-rate mortgage is about to reset, refinancing into a fixed-rate loan can add payment stability. If you need to remove a borrower after divorce or separation, a refinance is often the cleaner path because it creates a new loan obligation.
A refinance is also the better tool when you want to use equity. A cash-out refinance lets you replace the current mortgage with a larger one and receive the difference in cash, subject to lender and loan-program limits.
The risk is resetting the clock. A new 30-year mortgage can lower the payment but stretch repayment over a longer period. That can increase total interest paid if you keep the loan for many years.
Recast vs. Refinance Example
Assume you owe $350,000 on a 30-year fixed mortgage at 6.5%, with 25 years left. Your principal and interest payment is about $2,363.
If you put $75,000 toward principal and recast the loan over the remaining 25 years at the same 6.5% rate, the payment falls to about $1,857. The loan balance drops, but the interest rate and remaining term stay the same.
A refinance works differently. If you refinance the remaining balance into a new 30-year loan, the payment depends on the new rate, closing costs and loan amount. A lower rate could create savings. A higher rate could erase them.
This is why the comparison starts with your goal. A recast answers, “How do I lower the payment on the loan I already have?” A refinance answers, “Is a new loan better than the one I have now?”
Costs And Cash Needed
A recast usually requires cash upfront because the lower payment comes from a lower principal balance. The servicer may also charge an administrative fee. Ask for the exact minimum principal payment, fee and processing timeline before sending funds.
A refinance usually requires closing costs. Those costs can be paid at closing, rolled into the new loan when allowed or covered through lender credits in exchange for a different rate. The cheapest-looking option is not always the lowest-cost option over time.
The CFPB’s Loan Estimate and Closing Disclosure forms are designed to show loan terms and costs so borrowers can compare mortgage offers and review final figures before closing.
Impact On Interest Rate And Loan Term
A recast keeps your current interest rate. That is a major advantage when your existing rate is below current market rates. It is a weakness when your current rate is high.
A refinance gives you a new rate. That makes it useful when rates fall, your credit profile improves or you qualify for a better loan structure.
The loan term also works differently. A recast usually recalculates the payment over the remaining term. A refinance can restart the term, shorten it or move into another structure, depending on the product you choose.
Impact On Monthly Payment
Both options can lower the monthly payment, but they do it through different levers.
A recast lowers the payment by reducing the balance and spreading that lower balance across the remaining term. It does not rely on a better interest rate.
A refinance lowers the payment through a new loan. The savings can come from a lower rate, a longer term or both. That flexibility helps with cash flow, but it can also increase total interest if the new term is much longer than the remaining term on your current loan.
Impact On Home Equity
A recast increases your home equity because you pay down the principal balance. You are moving cash into the home.
A rate-and-term refinance may keep your equity position roughly similar, aside from closing costs and any amount rolled into the loan. A cash-out refinance reduces equity because you borrow more than you currently owe and take the difference in cash.
This makes the choice partly about liquidity. Recasting can lower the payment, but it ties up cash in the property. Refinancing can preserve or access cash, but the new loan has to justify its cost.
Which Option Is Better?
A recast is usually better when you have extra cash, like your current interest rate and want a lower required payment. It is a narrow tool, but it does that job well.
A refinance is usually better when you need a different loan. That could mean a lower rate, a shorter term, a cash-out option, a fixed rate instead of an adjustable rate or a change to who is legally responsible for the mortgage.
The wrong choice is the one that solves the wrong problem. A recast will not lower a high interest rate. A refinance may not make sense if it gives up a strong existing rate just to reduce the monthly payment.
Questions To Ask Before You Choose
Ask Your Servicer About A Recast
Before making a large principal payment, ask whether your loan is eligible for recasting. Then ask for the minimum principal payment, fee, required documents and expected date of the new payment.
Also ask whether the recast affects escrow. A recast typically changes the principal and interest portion of the payment, not the taxes and insurance collected through escrow.
Ask A Lender About A Refinance
For a refinance, ask for the interest rate, annual percentage rate, closing costs, new loan term and cash needed to close. Then compare the payment savings with the cost of the new loan.
The break-even point matters. If a refinance costs $6,000 and lowers the payment by $200 per month, it takes 30 months to recover the cost before the refinance starts producing net savings.
Check Your Timeline
Your expected time in the home can decide the answer. A refinance with high upfront costs is harder to justify if you plan to sell soon. A recast can still help with near-term payment relief, but only if you are comfortable putting a large amount of cash into the home.
The Bottom Line
A mortgage recast lowers the payment on your existing loan after a large principal payment. It keeps the same interest rate and usually keeps the remaining term.
A refinance replaces your current mortgage with a new loan. It can change the rate, term, loan type or equity strategy, but it requires a new approval and closing costs.
Use a recast when the current loan is worth keeping and your main goal is a lower payment. Use a refinance when the current loan no longer fits.
Frequently Asked Questions
What Is The Main Difference Between A Recast And A Refinance?
A recast keeps your existing mortgage and recalculates the payment after a large principal payment. A refinance replaces your existing mortgage with a new loan.
Does A Mortgage Recast Change Your Interest Rate?
No. A mortgage recast keeps your existing interest rate. The payment changes because the loan balance is lower and the servicer re-amortizes the remaining balance.
Does A Refinance Change Your Interest Rate?
It can. A refinance creates a new mortgage, so the rate depends on current market conditions, your qualifications, the loan type and the lender’s pricing.
Is A Recast Cheaper Than Refinancing?
A recast is usually cheaper because it does not create a new mortgage closing. The main cost is the large principal payment, plus any servicer fee. A refinance has closing costs and requires a new loan approval.
Can Every Mortgage Be Recast?
No. Recast availability depends on your loan type, investor rules and servicer policies. Ask your servicer before sending a large principal payment if your goal is to lower the required payment.
Can You Recast After Making Extra Mortgage Payments?
Possibly. Some servicers allow a recast after a substantial principal payment. Regular extra payments reduce your balance and interest over time, but they do not automatically lower the required monthly payment.
Does A Recast Remove Mortgage Insurance?
A recast does not automatically remove mortgage insurance. Mortgage insurance cancellation follows separate rules, and the servicer must evaluate whether the loan qualifies.
Is Refinancing Better If Rates Drop?
Refinancing can be better when current rates are low enough to offset the closing costs and improve the loan. The break-even point shows how long it takes monthly savings to recover refinance costs.
Can You Take Cash Out With A Recast?
No. A recast requires you to put money into the mortgage. A cash-out refinance is the option that lets you replace the current mortgage with a larger one and receive cash back, subject to loan limits and approval.
Should You Recast Or Refinance After Selling Another Home?
A recast can make sense if you want to apply sale proceeds to your current mortgage and lower the payment without changing the loan. A refinance may make more sense if you also need a new rate, new term or cash-out structure.
