Recast Mortgage: What Is It & How Do You Calculate It?

Written by JD Esajian

If you are a homeowner with monthly mortgage obligations, you may have already considered making extra mortgage payments ahead of schedule to ease the burden of future costs. After all, those awarded the luxury of allocating more capital to their mortgage in the earlier stages of amortization will have an easier time paying back their debts later. However, it is worth noting that there’s more than one way to lower monthly payment obligations. Instead of simply paying more each month, a recast mortgage allows homeowners to keep their interest rate the same while lowering the minimum payment.

The mortgage recast process has already helped countless homeowners, which begs the question: What does it mean to recast a mortgage? Better yet, is a mortgage recast a good idea? The following guide is intended to help homeowners familiarize themselves with this simple tool and provide enough information to determine if the process is right for them.

What Is A Recast Mortgage?

A recast mortgage is a process of reevaluating monthly mortgage payments by taking the loan’s balance and dividing it by the remaining months left on the mortgage term. In doing so, homeowners ahead of schedule may be eligible to reduce their monthly payments. In other words, homeowners who have either contributed extra payments or even made a large, one-time payment (in addition to their monthly mortgage obligations) will be the primary beneficiaries of the recast mortgage process. If for nothing else, those ahead of their amortization schedule are more likely to be eligible to reduce their monthly payments; all the bank does is adjust the remaining balance to the months remaining on the loan and recalculates a new monthly payment.

How Does Mortgage Recasting Work?

To recast a mortgage, homeowners will first need to meet with their lender to discuss whether or not a recast is possible. Depending on your mortgage provider, this option may or may not be a possibility. There are fees associated with a recast mortgage that will depend on your lender, so this is also an important topic to review.

If you do decide to move forward with a recast mortgage, several steps will take place. The first step will usually involve the homeowner making a lump-sum mortgage payment. The amount can vary; however, most lenders will require a payment of at least $5,000. These payments will be applied to your outstanding loan amount, allowing the total amount owed to decrease. A lender will then reevaluate the loan terms by using the reduced balance and timeframe of the original mortgage. Remember that a mortgage recast is often utilized by homeowners who have paid a significant portion of their mortgage or who have made extra payments over time.

Depending on the remaining amount of the loan, homeowners should see their monthly required payments decrease. This is a result of the increased monthly payments or lump sum reducing the mortgage’s remaining balance. Be aware, a recast mortgage loan will keep the original interest rate of the mortgage. The timeline of the initial mortgage will also remain the same, but––as always––homeowners will be permitted to make increased payments in the future. Make note of your lender’s requirements for a recast mortgage, as homeowners are often only allowed to recast a mortgage once.

Mortgage Recast Calculator

To calculate the terms of mortgage recast, you will need to have a few numbers ready: the remaining balance of your loan, the number of months left, and the interest rate. By looking at these factors, you will get a better idea of how your existing mortgage payment could change. Several useful online recast calculators can help you get a better idea of how your payments could change. For example, this mortgage recast calculator allows homeowners to insert each variable and get a better idea of their new payments.

Example Of Recast Mortgage

On the surface, the mortgage recast process can be confusing to those who are unfamiliar with it. Therefore, instead of convoluting the concept with arbitrary numbers, it’s probably better for many people to look at a real-world example. Let’s say you are locked into a 30-year fixed-rate mortgage at 4.99% with a remaining balance of $200,000. In this particular scenario, monthly payment obligations are approximately $1,072.43. That said, you are also fortunate enough to have saved up $40,000, not the least of which you intend to put towards your mortgage principal. In doing so, you can reduce your remaining balance from $200,000 to $160,000 almost overnight. Immediately after the lump-sum payment and a subsequent mortgage recast, monthly payments would drop to somewhere in the neighborhood of $870.81. The recast mortgage process will have had homeowners trade their $40,000 for a discount of $201.62 each month.

How To Qualify For Mortgage Recasting

The recast mortgage process has proven to be an invaluable tool for many homeowners. Unfortunately, however, mortgage recasting isn’t made available to all homeowners. Mortgage recasting isn’t universally offered by all lenders, nor are all mortgages eligible. Therefore, let’s take a look at what you might need to qualify for mortgage recasting:

  • Many lenders require a minimum lump-sum payment of at least $5,000. However, others lenders will require the payment to represent a percentage of the remaining principal.

  • More often than not, participating lenders will require homeowners to have a certain amount of equity in the home before they can even consider a mortgage recast.

  • Mortgage recasting doesn’t work on government-backed loans.

  • Most jumbo loans don’t qualify to be recasted.

  • A great deal of lenders will require a clean history of timely payments.

Types Of Mortgages That Can Be Recast

As mentioned before, not all mortgages can be recast. Due to current restrictions and rules, neither FHA, USDA or VA loans can be recast. On top of that, most jumbo loans do not qualify for the mortgage recast process. There are, however, two specific types of mortgages than can be recast:

  1. Negative Amortization Loans

  2. Option Adjustable-Rate Mortgages (Option ARM)

Negative Amortization Loans

Not only can a negative amortization loan qualify for recasting, but the terms of the recast can be written into the terms of the loan. More specifically, the payment structure of a traditional negative amortization loan permits borrowers the ability to schedule a payment that is less than the loan’s interest charge. The small payment creates deferred interest, which is then tacked on to the loan’s principal balance. Since the incremental payments increase the principal, the nature of negative amortization loans requires a recast to officially pay off the debt.

Option Adjustable-Rate Mortgages (Option ARM)

Option adjustable-Rate mortgages (Option ARM) are the same as negative amortization loans, only borrowers are given the option to pay off all of the loan’s balance and interest or just some of the interest. Consequently, option ARMs are more flexible than their negative amortization loan counterparts. Still, there’s a chance the borrower ends up with more debt in the long run because of fluctuations in interest rates.

Mortgage Recast Vs. Refinance

If you find yourself ineligible for a recast mortgage, or it simply will not benefit your situation, another option to look into is refinancing. Refinancing describes a process where you replace your primary mortgage loan with a new loan. By taking a new loan, often with a different lender, you can take advantage of a different loan term and interest rate. Some of the advantages and disadvantages of refinancing are discussed below.

Pros Of Refinancing

Refinancing differs from a mortgage recast in that it often allows for a reduced interest rate in addition to lower monthly payments. Homeowners typically turn to refinancing under similar circumstances to a recast mortgage. Depending on the loan to value ratio, refinancing can benefit homeowners greatly by leading to a decreased interest rate. Further, you might even pay off your loan faster or spend less over the life of the loan. Cashing out on some of your equity can also help you cover some of your expenses.

Cons Of Refinancing

On the other hand, there are a few trade-offs to consider when looking into refinancing as an option. Refinancing will typically restart the time frame for the mortgage. It could result in a longer amount of time for the loan to be paid off and consequently could result in more interest paid over time, despite the lower interest rate. Refinancing will also result in closing costs, including appraisal fees and more. These will vary based on your lender, although the costs associated with refinancing are typically higher than a recast mortgage.


Recast Mortgage Pros & Cons

While the recast mortgage process has helped countless homeowners reduce their monthly payments, borrowers must weigh the pros and cons themselves. Everyone’s financial situation is different, and it’s not until you can look at each benefit and drawback that you will be able to tell if the recast mortgage process is right for you.

Pros Of Recasting Mortgage

There are numerous pros to a recast mortgage, all of which may be appealing to homeowners (particularly as they approach retirement). Here are a few of the benefits that may make a mortgage recast worth considering:

  • Lower Mortgage Payments: By making extra payments and recasting your mortgage, you can decrease your minimum payment moving forward. This is great for homeowners looking to use that extra money to invest or add to their savings. The timeframe of the original mortgage will remain the same, meaning you do not have to add time to your loan.

  • Simplicity: As you look into how to recast a mortgage, you may notice it is often much simpler when compared to refinancing a mortgage. Homeowners often need to meet eligibility requirements and meet with a lender to do so. The simplicity involved is great for homeowners looking to change the terms of their mortgage without re-qualifying for a loan.

  • Keep Your Interest Rate: Recasting a mortgage involves using the existing loan balance and the time frame left on the mortgage, and therefore will not change the interest rate. For homeowners with a favorable interest rate, a mortgage recast represents the opportunity to benefit from lower mortgage payments while keeping the same interest rate.

Cons Of Recasting Mortgage

While there are numerous benefits to recasting a mortgage, the process can also have a few cons that homeowners should be aware of. Mind due diligence and consider the following factors before deciding on a recast mortgage:

  • Higher Mortgage Payments: It is possible for a mortgage recast to actually increase your monthly payments. This can occur when homeowners make low monthly mortgage payments and are required by lenders to recast the mortgage. While uncommon, these situations can and do occur.

  • Fees: There are fees involved in recasting a mortgage. These will vary depending on your lender, but homeowners should expect to pay anywhere from $0 to $500. While the fee may be small, it is important to weigh the benefits of a lower payment when considering recasting a mortgage.

  • Minimum Payments: Many lenders will require a minimum lump-sum payment in order to qualify for a mortgage recast. If you have been making extra mortgage payments over time, you may not be affected by this. However, if a lump sum is necessary, homeowners should pay careful attention to how it affects their finances.

Mortgage Recast Vs. Principal Payment

The nature of a mortgage recast will require borrowers to make at least one large payment to their principal ahead of schedule. However, it is worth noting that the addition of a single lump-sum payment doesn’t initiate the mortgage recast process. It is entirely possible to make a large payment ahead of schedule without recasting the mortgage. A large payment (above and beyond monthly mortgage obligations) can place borrowers ahead of schedule, but it won’t change the schedule at all. Monthly payments will remain unchanged, despite the extra installment. On the other hand, a mortgage recast will simultaneously change the amortization schedule and the amount the borrower is expected to pay each month.


A mortgage recast can be a great opportunity for homeowners looking to decrease their monthly mortgage payments. Particularly as homeowners approach retirement, the opportunity to have a little extra money each month may be beneficial. Remember, even if you speed up your mortgage payments or contribute a lump sum to your loan, you are not required to change the terms of your original mortgage. Homeowners should do research to find what will work best for their situation. A mortgage recast may be helpful for some, but it is certainly not a one-size-fits-all option.
