Reverse Mortgage

Estimating Cash Available From a Reverse Mortgage

A reverse mortgage lets homeowners 62 or older convert part of their home equity into cash, without monthly payments — the loan balance grows over time instead, and is repaid only when the borrower sells, moves out permanently, or passes away. Enter your home value, age, any existing mortgage balance, and estimated principal limit factor to see roughly how much cash you could access.

This is genuinely different from the Home Equity / HELOC Calculator calculator, which covers a traditional home equity loan or HELOC — both require monthly payments and qualifying on income and credit. A reverse mortgage (specifically the FHA-insured Home Equity Conversion Mortgage, or HECM, by far the most common type) requires neither, but is only available starting at age 62.

Worked Example

A $400,000 home, age 70, no existing mortgage, an estimated principal limit factor of 50%, and 3% estimated closing costs:

1. Estimated principal limit: $400,000 × 50% = $200,000.
2. Estimated closing costs: $400,000 × 3% = $12,000.
3. Net proceeds available: $200,000 − $0 − $12,000 = $188,000.

If this same homeowner still owed $150,000 on an existing mortgage, that balance would be paid off first from the proceeds, leaving $38,000 in net proceeds instead.

Key Factors to Consider

• The loan balance grows over time, not just the interest rate applying to a fixed amount. Because there are no required monthly payments, interest and mortgage insurance premiums accrue and are added to the loan balance each period — the amount owed grows continuously over the life of the loan, which reduces the home equity left for the borrower or their heirs compared to a traditional mortgage that shrinks over time.
• A reverse mortgage is federally regulated as a “non-recourse” loan, meaning the borrower (or their estate) never owes more than the home is worth. If the loan balance eventually exceeds the home’s sale value, FHA mortgage insurance covers the difference — the borrower’s other assets and heirs are protected from owing more than what the home itself is sold for.
• HUD-required independent counseling is a mandatory step before obtaining an HECM specifically because these products are genuinely complex. A borrower must complete counseling with a HUD-approved counselor before applying, which is designed to ensure the tradeoffs (loan growth, reduced inheritance, ongoing property tax/insurance obligations) are clearly understood before committing.
• The borrower remains responsible for property taxes, homeowners insurance, and home maintenance for the life of the loan. Falling behind on these ongoing obligations is one of the more common ways a reverse mortgage can go into default, even though there’s no required monthly loan payment itself — this is a real, ongoing responsibility that doesn’t disappear just because the loan payment does.

Common Mistakes

• Assuming the principal limit factor is a fixed percentage for everyone. The real HUD table increases the accessible share of home value as the borrower gets older — this calculator’s default is a rough age-based estimate, not the actual published table, so treat it as a starting point to confirm with a real lender.
• Forgetting an existing mortgage must be paid off first. Any current mortgage balance comes directly out of the principal limit before any cash reaches the borrower — it isn’t simply combined with the new loan.
• Thinking a reverse mortgage means giving up home ownership. The borrower keeps the title and remains responsible for property taxes, insurance, and upkeep throughout — the loan is simply secured by the home, the same way a traditional mortgage is.
