What AARP's reverse mortgage calculator does

AARP's reverse mortgage calculator is a tool that estimates how much money you could borrow against your home's value if you take out a reverse mortgage. You enter your age, your home's estimated value, how much you still owe on any existing mortgage, and your zip code. The calculator then shows you a rough estimate of the loan amount you might receive.

The calculator does not lock in any numbers or commit you to anything. It is meant to give you a ballpark figure so you can decide whether a reverse mortgage is worth exploring further. The actual amount you could borrow depends on factors the calculator cannot know—your exact credit history, the precise condition of your home, current interest rates on the day you explore, and which lender you choose.

AARP offers this tool as part of its educational materials on reverse mortgages. The organization does not lend money itself or take a commission if you move forward with a loan. The calculator is free and does not require you to enter contact information or create an account.

Key Takeaways

  • AARP's calculator gives you an estimate based on age, home value, existing debt, and location—not a binding offer or final loan amount.
  • The actual loan amount depends on current interest rates, your credit, and your lender's specific terms, which change over time.
  • A reverse mortgage lets you borrow against home equity if you are 62 or older, but you remain responsible for property taxes, insurance, and maintenance.
  • The calculator is one step in understanding the concept; speaking with a HUD-approved counselor is required before you can actually take out a reverse mortgage.
  • Reverse mortgages have upfront costs and ongoing fees that reduce the amount you actually receive, and these vary by lender.

How to use the calculator and what information you need

Start by gathering four pieces of information: your age (you must be at least 62), your home's current market value (a recent tax assessment or real estate website estimate works), the balance on any mortgage or home equity line of credit still attached to the property, and your zip code. The calculator uses the zip code to account for regional differences in home values and lending practices.

Enter these numbers into the AARP calculator fields. The tool will show you an estimated loan amount within seconds. This number represents the maximum you might borrow, though in practice most borrowers take less. The calculator may also show you different scenarios—for example, what you could borrow if you took a lump sum versus a line of credit that you draw from over time.

Keep in mind that the calculator works with broad assumptions. It does not know whether your home needs a new roof, whether you have missed property tax payments, or whether your credit score is excellent or poor. All of these affect what a real lender would offer. The estimate is a starting point, not a prediction of what will actually happen.

What the calculator does not tell you

The calculator shows you a potential loan amount but does not break down the costs you will pay to get that money. A reverse mortgage comes with an origination fee (typically 1 to 2 percent of the home value), mortgage insurance premiums, appraisal fees, title search fees, and closing costs. These can add up to several thousand dollars and are usually rolled into the loan itself, which means you owe them back when the loan comes due.

The calculator also does not account for interest rates, which change daily. The estimate it gives you is based on general assumptions, not the rate you would actually receive. A quarter-point difference in interest rate can change your loan amount by thousands of dollars. You would need to get a formal quote from a lender to see the real number.

Finally, the calculator does not address what happens after you receive the money. If you take a reverse mortgage, you still have to pay property taxes, homeowners insurance, and maintain the home. If you do not, the lender can call the loan due. The calculator cannot predict whether you will be able to keep up with these obligations over time, or what will happen to your home if you move into assisted living or a nursing home.

The difference between estimate and actual loan offer

An estimate from the AARP calculator is educational. An actual loan offer from a lender is a legal document that commits both you and the lender to specific terms. The offer will include the exact interest rate, the exact fees you will pay, the exact monthly payment (if you choose a payment plan), and the exact conditions under which the lender can demand repayment.

To get a real offer, you will need to contact a lender directly and provide detailed financial and property information. The lender will order an appraisal of your home, pull your credit report, and verify your income and assets. This process takes one to three weeks. Only after all of that will the lender issue a formal offer with numbers you can actually rely on.

Before you can close on a reverse mortgage, federal law requires you to meet with a HUD-approved counselor who will review the loan terms, explain the costs, and make sure you understand what you are signing. This counseling is free and is meant to protect you from making a decision you do not fully understand. The counselor does not work for the lender and has no stake in whether you proceed.

When the calculator is useful and when it is not

The calculator is useful if you are in the early stages of wondering whether a reverse mortgage makes sense for your situation. If you own a home worth $300,000 and have no mortgage, the calculator can show you that you might borrow $150,000 to $180,000 (the exact amount depends on your age and location). That kind of rough number helps you decide whether it is worth learning more.

The calculator is not useful if you are trying to make a final decision or compare offers from different lenders. For that, you need real quotes with real interest rates and real fees. You also should not rely on the calculator if your home value is uncertain, if you have a complex mortgage situation, or if you are not sure whether you will stay in the home long enough to make the loan worthwhile.

Many people use the calculator to start a conversation with a financial advisor or a HUD-approved counselor. They bring the estimate and say, "Is this realistic for my situation?" That is a smart use of the tool. The calculator opens the door; it does not answer the question of whether you should walk through it.

Other resources AARP offers alongside the calculator

AARP publishes written guides that explain how reverse mortgages work, who they are right for, and what the risks are. These guides go into detail about the different types of reverse mortgages (federally insured Home Equity Conversion Mortgages, or HECMs, are the most common), the costs involved, and what happens to your home and your heirs if you take one out.

AARP also maintains a list of HUD-approved counselors in your area. These counselors will review your specific situation, answer questions the calculator cannot, and help you think through whether a reverse mortgage fits your goals. Many offer sessions by phone or video, and the service is free.

If you decide to move forward, AARP recommends getting quotes from at least three lenders before you choose one. Rates and fees vary significantly, and shopping around can save you thousands of dollars. AARP does not endorse specific lenders, but it does provide information on how to compare offers side by side.

Frequently Asked Questions

Does using the AARP calculator commit me to anything?

No. The calculator is informational only. Entering your information does not create an obligation, does not appear on your credit report, and does not start a loan process. You can use it as many times as you want with different numbers to see how age or home value changes the estimate.

Why does the calculator ask for my zip code?

Reverse mortgage amounts vary by region because home values, property taxes, and lending practices differ. Your zip code helps the calculator account for these regional differences and give you a more accurate estimate for your area.

What if the calculator's estimate seems too high or too low?

The estimate is based on broad assumptions. If it does not match what you expect, double-check that you entered your home value correctly and that you are at least 62 years old. If the numbers still seem off, contact a HUD-approved counselor or a lender who can review your specific situation and explain the difference.

Can I use the calculator if I still owe money on my mortgage?

Yes. Enter the amount you still owe, and the calculator will subtract it from the home's value to show you how much equity you could borrow against. You will have to pay off your existing mortgage with the reverse mortgage proceeds before you can access any remaining funds.

Is the calculator's estimate the same as what I would actually receive?

No. The calculator gives you a ballpark figure. The actual amount depends on the interest rate at the time you explore, the lender's fees, the results of the home appraisal, and your credit history. You need a formal quote from a lender to see the real number.
