What This Calculator Does
A reverse mortgage lets homeowners age 62 and older convert part of their home equity into cash without selling the home or taking on a monthly mortgage payment. The most common type is the Home Equity Conversion Mortgage (HECM), which is insured by the Federal Housing Administration (FHA). This calculator estimates how much you can borrow based on your age, home value, existing mortgage balance, and the expected interest rate.
The loan does not come due until the last borrower leaves the home, sells it, or passes away. You remain the owner of the property and are responsible for paying property taxes, insurance, and maintenance. When the loan ends, the balance (including accrued interest and mortgage insurance) is repaid, typically from the sale of the home. Any remaining equity belongs to you or your heirs. For a different approach to tapping equity, see our Home Equity Loan Calculator or our HELOC Calculator.
2026 HECM Lending Limit
HUD raised the HECM Maximum Claim Amount (MCA) limit to $1,249,125 for 2026, up from $1,209,750 in 2025. This is 150% of the FHFA conforming baseline loan limit of $832,750. The limit applies nationwide, including Alaska, Hawaii, Guam, and the U.S. Virgin Islands. If your home is worth more than $1,249,125, the calculator caps the value used for the principal limit calculation at this amount. Borrowers with higher-value homes may want to compare HECM against proprietary (jumbo) reverse mortgages, which are not subject to the FHA cap.
Inputs Required
- Home Value: Your current estimated home value. The calculator uses the lesser of this or the $1,249,125 lending limit.
- Youngest Borrower Age: Must be at least 62. The age of the youngest borrower or eligible non-borrowing spouse determines the principal limit factor.
- Expected Interest Rate: The 10-year CMT or SOFR swap rate plus the lender margin, rounded to the nearest eighth. This is not the same as your accrual rate. Higher expected rates reduce your principal limit.
- Existing Mortgage Balance: Any current liens must be paid off at closing from the reverse mortgage proceeds.
- Other Closing Costs: Title insurance, appraisal, recording fees, and HUD counseling. Most of these can be financed into the loan.
Outputs Provided
- Maximum Claim Amount: The lesser of your home value or the $1,249,125 HECM lending limit.
- Principal Limit Factor: The percentage of the MCA you can access, based on your age and expected rate.
- Principal Limit: MCA multiplied by the PLF. This is the total pool of money available.
- Net Cash Available: Principal limit minus existing mortgage payoff and all closing costs.
- Estimated Tenure Payment: Approximate monthly payment you could receive for as long as you live in the home.
How the Calculation Works
The HECM proceeds calculation has three main steps:
Step 1: MCA = Lesser of (Home Value, $1,249,125)
Step 2: Principal Limit = MCA x Principal Limit Factor (PLF)
Step 3: Net Proceeds = Principal Limit - Existing Mortgage - Closing Costs
The Principal Limit Factor is a HUD-published number that depends on two inputs: the age of the youngest borrower and the expected interest rate. Older borrowers get a higher PLF because the loan is statistically expected to run for fewer years. Lower expected rates also produce a higher PLF. The PLF tables currently in use were published by HUD in FY2018 and have not been updated since. A 70-year-old at a 7.0% expected rate has a PLF of approximately 46.6%, while an 80-year-old at the same rate has a PLF of approximately 55.2%.
Closing costs on a HECM include the upfront FHA mortgage insurance premium (2% of the MCA), the lender origination fee (capped at $6,000 by HUD), and third-party costs like title insurance, appraisal, and recording fees. The upfront MIP is the largest single cost. On a $500,000 home, it is $10,000. On a home at the lending limit, it reaches $24,983. Most closing costs can be financed into the loan, so actual cash out of pocket at closing is typically under $200 (just the HUD counseling fee, which averages $125 to $175).
How to Use the Calculator
- Enter your estimated home value. If your home is worth more than $1,249,125, the calculator automatically caps it at the HECM lending limit.
- Set the age of the youngest borrower. Both spouses must be at least 62, and the younger spouse's age drives the calculation.
- Adjust the expected interest rate. Your lender can provide the current expected rate, which is typically the 10-year CMT plus a margin of around 2.5% to 3.0%.
- Enter any existing mortgage balance that must be paid off at closing.
- Adjust other closing costs if you have estimates from a lender or title company.
- Review the net cash available and the estimated monthly tenure payment.
Example Calculations
Example 1: Retired Couple, Age 72, Modest Home
Robert and Margaret, both 72, own a $450,000 home in Tucson, Arizona, free and clear. They want supplemental retirement income. Using a 7.0% expected rate:
- Maximum claim amount: $450,000 (below the lending limit)
- PLF at age 72, 7.0% rate: approximately 47.6%
- Principal limit: $450,000 x 0.476 = $214,200
- Upfront MIP (2%): $9,000
- Origination fee: $6,000 (capped)
- Other closing costs: $3,500
- Net cash available: $214,200 - $18,500 = $195,700
- Estimated tenure payment: approximately $1,350/month for life
Robert and Margaret could take the $195,700 as a lump sum, a line of credit, monthly tenure payments, or a combination. The line of credit option grows over time at the accrual rate, which can be attractive if they do not need all the money immediately.
Example 2: Single Homeowner, Age 80, High-Value Home
Patricia, an 80-year-old widow in San Diego, has a home worth $1,800,000 with a $200,000 existing mortgage. She wants to pay off the mortgage and have cash for in-home care. Using a 7.0% expected rate:
- Maximum claim amount: $1,249,125 (capped at lending limit, not $1,800,000)
- PLF at age 80, 7.0% rate: approximately 55.2%
- Principal limit: $1,249,125 x 0.552 = $689,517
- Upfront MIP (2% of MCA): $24,983
- Origination fee: $6,000 (capped)
- Other closing costs: $4,000
- Existing mortgage payoff: $200,000
- Net cash available: $689,517 - $234,983 = $454,534
Because her home exceeds the lending limit, $550,875 of her equity is not accessible through a HECM. A proprietary jumbo reverse mortgage could tap that additional equity, but those products are not FHA-insured and do not offer the same non-recourse protections. Patricia should compare both options with a HUD-approved counselor.
Real-World Scenarios
Paying Off an Existing Mortgage to Free Up Cash Flow
James, 68, has a $1,200 monthly mortgage payment that is straining his fixed retirement income. His home is worth $600,000 and he owes $180,000. A HECM pays off the $180,000 mortgage and eliminates the $1,200 monthly payment. After closing costs of approximately $21,000, he has roughly $130,000 in remaining proceeds he can draw as a line of credit. The elimination of his mortgage payment improves his monthly cash flow by $1,200, and the line of credit is available for emergencies. He uses our Mortgage Payoff Calculator to compare this against making extra payments on his existing loan.
Delaying Social Security with a Reverse Mortgage Bridge
Linda, 63, wants to delay claiming Social Security until age 70 to maximize her benefit. Her home is worth $500,000 and is paid off. She uses a HECM line of credit to draw $2,500 per month for 7 years (approximately $210,000 total) as a bridge strategy. By waiting until 70, her Social Security benefit increases by roughly 76% compared to claiming at 62. The reverse mortgage line of credit costs her accrued interest, but the higher lifetime Social Security benefit more than compensates. This strategy, sometimes called the "reverse mortgage bridge," has been studied by researchers at The New School's Retirement Equity Lab.
Aging in Place with Home Modifications
Frank and Dolores, both 75, want to stay in their $700,000 home but need $60,000 for a walk-in shower, chair lift, and widened doorways. Their PLF at age 75 and 7.0% expected rate is approximately 50.7%, giving a principal limit of about $354,900. After closing costs of roughly $24,000, they have $330,900 available. They take $60,000 as a lump sum for renovations and leave the rest as a growing line of credit for future care needs. The modifications let them age in place, which is far cheaper than assisted living at an average of $5,800 per month according to Genworth's 2025 Cost of Care Survey.
Why This Calculation Matters
The Urban Institute reported in 2024 that homeowners age 62 and older hold approximately $12.5 trillion in home equity, the largest store of wealth for this demographic. Yet most retirees do not factor home equity into their retirement income plan. A HECM reverse mortgage is one of the few tools that lets you access this equity without moving or taking on a monthly payment you may not be able to afford on a fixed income.
The trade-off is real. The loan balance grows over time because interest and mortgage insurance premiums accrue. This reduces the equity remaining for you or your heirs. The 30-year fixed mortgage rate averaged 6.71% as of September 3, 2026 per Freddie Mac, and HECM accrual rates are typically similar or slightly higher. Over 15 to 20 years, a growing balance can consume a substantial portion of home value. The decision to use a reverse mortgage should be made with a HUD-approved housing counselor and a financial advisor who can model the long-term impact on your estate.
Common Mistakes to Avoid
- Taking a HECM too young: The PLF at age 62 is roughly 40% at a 7.0% expected rate, compared to about 55% at age 80. Waiting even a few years can meaningfully increase your available proceeds. Every year you wait, the PLF increases.
- Forgetting about taxes and insurance: You must pay property taxes, homeowners insurance, and maintain the home. Failure to do so is the most common reason for reverse mortgage default and foreclosure. Set aside funds for these obligations before spending the proceeds.
- Overlooking the non-borrowing spouse: If one spouse is under 62, they cannot be a borrower. If the borrowing spouse dies or moves out, the loan becomes due. HUD rules protect eligible non-borrowing spouses from immediate foreclosure, but they cannot receive any remaining proceeds. Both spouses should be on the loan if possible.
- Ignoring the growing balance: Because you make no monthly payments, interest and MIP accrue on the outstanding balance. A $200,000 loan at 7% grows to roughly $540,000 after 14 years. Understand how the balance will grow over your expected time in the home.
- Not comparing to alternatives: A cash-out refinance, HELOC, or home equity loan may be cheaper if you can afford the monthly payments. A downsizing sale may free up more cash. Use our Refinance Calculator to compare a cash-out refinance against a reverse mortgage.
Limitations of This Calculator
This calculator provides an estimate based on a representative subset of the HUD Principal Limit Factor table using bilinear interpolation. The actual PLF may differ slightly from the interpolated value. The expected interest rate you enter is an estimate; your lender will calculate the exact rate at application. Closing costs vary by location, lender, and title company. The tenure payment estimate uses an approximate life expectancy factor and does not account for the HECM servicing fee set-aside or property charge set-asides. This tool does not constitute a loan approval, a formal principal limit disclosure, or financial advice. Federal law requires you to complete a session with a HUD-approved housing counselor before applying for a HECM. Consult a qualified reverse mortgage lender for an official illustration.
