About the Reverse Mortgage Calculator

A reverse mortgage โ€” most commonly a Home Equity Conversion Mortgage (HECM) โ€” allows homeowners aged 62 and older to convert part of their home equity into cash without making monthly mortgage payments. The loan is repaid when the borrower sells the home, moves out permanently, or passes away.

The amount you can borrow depends on three main factors: your age (older borrowers qualify for more), your home's appraised value (up to the FHA lending limit), and current interest rates (lower rates mean higher proceeds). This calculator uses simplified principal limit factors based on HUD guidelines to estimate your available proceeds.

This is an estimation tool only. Actual HECM proceeds depend on additional factors including property type, existing mortgage balances, and upfront costs. Always consult a HUD-approved HECM counselor before applying. Understanding the approximate principal limit before you meet with a counselor empowers you to ask the right questions and evaluate whether a reverse mortgage will meaningfully supplement your retirement income or cover essential expenses.

When This Page Helps

Reverse mortgages are complex products with significant trade-offs. Getting an estimate before speaking with a lender helps you understand whether the proceeds will meet your needs and how much equity you're converting. Use this calculator as a starting point to compare the lump sum, line of credit, and monthly payment options. Understanding the trade-offs before you engage with a lender also protects you from high-pressure sales tactics that are unfortunately common in the reverse mortgage industry.

How to Use the Inputs

  1. Enter the youngest borrower's age (must be 62 or older).
  2. Enter your home's estimated current market value.
  3. Enter any existing mortgage balance that must be paid off first.
  4. Set the expected interest rate (check current HECM rates).
  5. Review the estimated available proceeds after paying off existing liens.
  6. See how the proceeds translate to monthly payments over various terms.
Formula used
Principal Limit = Home Value (capped at FHA limit) ร— Principal Limit Factor (based on age and rate). Net Proceeds = Principal Limit โˆ’ Existing Mortgage โˆ’ Upfront Costs (2% initial MIP + origination fee). Monthly Payment (tenure) = Net Proceeds รท Months of life expectancy. Note: Actual HUD PLF tables are more granular.

Example Calculation

Result: Estimated proceeds: ~$149,000

At age 72 with a 6.5% expected rate, this calculator's simplified principal-limit factor is about 0.483. Applied to a $450,000 home value, that produces a gross principal limit of roughly $217,350. After subtracting the existing $50,000 mortgage, $9,000 of initial MIP, about $6,000 of origination fee, and $3,500 of other closing costs, the remaining proceeds are about $148,850.

Tips & Best Practices

  • The older you are when you take a reverse mortgage, the higher the principal limit factor and the more you can borrow.
  • Lower interest rates significantly increase available proceeds โ€” even a 0.5% drop can mean thousands more.
  • The FHA lending limit for HECM loans is $1,249,125 (2026) โ€” home values above this are capped.
  • A line of credit option grows over time at the same rate as the loan accrues interest, potentially increasing your available funds.
  • You remain responsible for property taxes, insurance, and maintenance โ€” failure to pay can trigger foreclosure.
  • HECM loans are non-recourse: you (or your heirs) will never owe more than the home's value at sale.

How HECM Reverse Mortgages Work

Unlike a traditional mortgage where you make monthly payments to the lender, a reverse mortgage pays you. The loan balance grows over time as interest and MIP accrue. You make no monthly payments โ€” the entire balance is repaid when you leave the home or pass away.

Principal Limit Factors

HUD publishes principal limit factor tables that determine the percentage of your home's value you can access. These factors depend on the youngest borrower's age and the expected interest rate. At age 62 with a 6% rate, the factor might be around 0.42 (42%). By age 80, it could exceed 0.58 (58%).

Current HECM Limit

For 2026, the FHA HECM lending limit is $1,249,125. Home values above that amount are capped when estimating available proceeds.

Is a Reverse Mortgage Right for You?

Reverse mortgages work best for homeowners who plan to stay in their home long-term, have significant equity, need supplemental retirement income, and have no plans to leave the home to heirs debt-free. If you're considering leaving your home within a few years or want to preserve equity for inheritance, other options like a HELOC or downsizing may be more appropriate.

Sources & Methodology

Methodology

This worksheet estimates HECM-style reverse-mortgage proceeds by capping the home value at the current FHA maximum claim amount, applying the calculator's simplified age-and-rate principal-limit-factor approximation, and then subtracting the existing mortgage balance plus simplified upfront costs: a 2% initial mortgage insurance premium, an origination-fee estimate, and a flat closing-cost allowance. It then converts the remaining proceeds into simple tenure, 10-year, and 15-year payment illustrations.

The page is intentionally framed as a screening estimate, not as the official FHA HECM calculator. Actual principal-limit factors, first-year draw restrictions, servicing set-asides, property-type rules, and lender-specific closing costs can materially change the final proceeds, so borrowers should confirm the final numbers with a HUD-approved HECM counselor and lender.

Frequently Asked Questions

  • The youngest borrower on the title must be at least 62 years old for a HECM reverse mortgage. If you have a younger spouse, their age is used for the calculation, resulting in lower proceeds. Some proprietary (jumbo) reverse mortgages may accept borrowers as young as 55.
