Reverse Mortgage Calculator: How Much Can You Borrow at Your Age
Published 06/05/2026 by

Summary:
A reverse mortgage calculator is a tool that estimates how much of your home equity you can borrow based on your age, your home’s value, and current interest rates.
Four inputs drive the result, and each one moves your number in a predictable direction.
- Age of the youngest borrower: Older borrowers qualify for a larger share of their home’s value.
- Home value: Counts up to the federal HECM limit; equity above the cap does not increase proceeds.
- Expected interest rate: Lower rates unlock a larger principal limit, higher rates shrink it.
- Payout option: Lump sum, line of credit, or monthly payments, each with different first-year limits.
Reverse mortgage math feels opaque because lenders quote it through federal tables most borrowers never see. The inputs are actually few, and you can estimate your number within a few percentage points before ever talking to a lender.

How a reverse mortgage calculator works
A reverse mortgage calculator multiplies your home’s appraised value (capped at the 2026 HECM limit of $1,249,125) by a principal limit factor, a percentage set by HUD tables based on your age and the expected interest rate. The result is your principal limit, the gross amount you can borrow.
Any existing mortgage balance is paid off first from the proceeds, and upfront costs are usually financed into the loan. What remains is the cash, credit line, or monthly payment you can actually receive.
The math: what borrowers typically qualify for
The table below estimates proceeds on a $500,000 home with no existing mortgage, using principal limit factors typical at recent expected rates. Exact figures come from HUD’s tables and shift with rates, so treat these as planning estimates.
| Age of youngest borrower | Approximate share of home value | Estimated principal limit |
|---|---|---|
| 62 | 35% to 40% | $175,000 to $200,000 |
| 70 | 40% to 45% | $200,000 to $225,000 |
| 75 | 45% to 50% | $225,000 to $250,000 |
| 80 | 50% to 55% | $250,000 to $275,000 |
| 85+ | 55% to 60% | $275,000 to $300,000 |
Two rules of thumb fall out of the table. Every year you wait adds roughly half a percentage point to your share, and any balance left on your current mortgage comes straight off the top of these numbers.
If your home is worth more than $1,249,125, the calculation stops at the cap. Equity above that line stays yours but cannot be tapped through a standard HECM.
How to estimate your reverse mortgage amount
You can get within a few percentage points of a lender quote in five steps.
- Start with your home’s market value, or the HECM limit of $1,249,125, whichever is lower.
- Find your age band in the table above and multiply your value by the matching percentage.
- Subtract your current mortgage balance, which must be paid off at closing.
- Subtract upfront costs if you plan to finance them: a 2% federal mortgage insurance premium, an origination fee capped at $6,000, and standard closing costs.
- Apply the first-year rule: with most payout options, you can draw no more than 60% of the principal limit in year one.
Reverse mortgage vs. HELOC vs. home equity investment
A reverse mortgage is one of three main ways to pull cash from home equity without selling. The right choice mostly depends on whether you can handle a monthly payment and how long you plan to stay in the home.
| Reverse mortgage | HELOC | Home equity investment | |
|---|---|---|---|
| Monthly payments | None required | Required | None; repaid at sale |
| Age requirement | 62 or older | None | None |
| Credit and income check | Financial assessment only | Full underwriting | Minimal |
| Upfront cost | High: insurance plus origination | Low | Moderate |
| You give up | Equity over time as interest accrues | Nothing if repaid | A share of future appreciation |
Borrowers under 62, or those who only need a modest credit line, usually come out ahead with a HELOC since the upfront costs are a fraction of a HECM’s. Comparing HELOC lenders side by side shows what rate and credit line your equity supports.
Homeowners who cannot qualify for a HELOC’s income requirements sometimes use a shared equity agreement instead, trading a slice of future appreciation for cash today with no monthly payment.
Pro Tip: The reverse mortgage line of credit has a growth feature most borrowers overlook. The unused portion grows at the loan’s interest rate plus the 0.5% insurance rate, so a credit line opened at 65 and left untouched can be dramatically larger at 75. Opening it early and not spending it is a legitimate retirement strategy.
Who qualifies for a reverse mortgage
HECM eligibility is set by HUD, not the lender, so the rules are the same everywhere. The core requirements:
- Age: The youngest borrower (or eligible non-borrowing spouse) must be 62 or older.
- Occupancy: The home must be your primary residence, and you must keep living in it.
- Equity: You generally need to own the home outright or have at least half the mortgage paid off.
- Counseling: A session with a HUD-approved counselor is mandatory before you can apply.
- Ongoing obligations: You must stay current on property taxes, homeowners insurance, and basic maintenance, or the loan can be called due.
What a reverse mortgage costs
Upfront costs are the main reason a reverse mortgage only makes sense if you plan to stay in the home for years. On a $500,000 home, expect roughly $10,000 in federal insurance (2% of value), up to $6,000 in origination fees, and a few thousand in standard closing costs.
Ongoing, the balance accrues interest plus a 0.5% annual insurance premium. No payments are due, so the balance grows instead of shrinking, which is the trade you are making for payment-free cash.
The insurance buys a real protection: HECMs are non-recourse. Neither you nor your heirs can ever owe more than the home sells for, even if the balance outgrows the value.
Key takeaways
- Reverse mortgage proceeds run from roughly 35% of home value at age 62 to 60% at 85 and up, set by HUD tables.
- The 2026 HECM limit caps the home value used in the calculation at $1,249,125.
- Your existing mortgage balance is paid off first and comes directly out of your proceeds.
- Upfront costs are steep: 2% federal insurance, up to $6,000 origination, plus closing costs. Short stays rarely pencil out.
- The loan is non-recourse. You and your heirs can never owe more than the home’s sale value.
FAQ
How much money can I get from a reverse mortgage at 62?
At current rates, a 62-year-old typically qualifies for 35% to 40% of the home’s appraised value, minus any existing mortgage balance and financed costs. On a $400,000 home with no mortgage, that is roughly $140,000 to $160,000.
Do I make monthly payments on a reverse mortgage?
No. Interest and insurance accrue onto the balance, which is repaid when you sell, move out for 12 months or more, or pass away. You remain responsible for property taxes, insurance, and upkeep.
What happens to my reverse mortgage when I die?
Your heirs have up to 12 months to sell the home, refinance the balance, or pay it off for 95% of appraised value if the balance exceeds it. Any equity left after repayment belongs to them.
Can I owe more than my home is worth?
No. HECM reverse mortgages are non-recourse loans backed by federal insurance, so the home itself is the only collateral. If the balance outgrows the value, the insurance fund absorbs the difference.
Does a reverse mortgage affect Social Security or Medicare?
Reverse mortgage proceeds are loan advances, not income, so Social Security and Medicare are unaffected. Need-based programs like Medicaid and SSI can be affected if proceeds sit in your bank account past the month received.
Can I get a reverse mortgage on a home worth more than the HECM limit?
Yes, but the HECM calculation only counts value up to $1,249,125. For homes well above the cap, proprietary jumbo reverse mortgages from private lenders can tap more equity, with different protections and costs.
A reverse mortgage decision touches everything else in retirement: income, taxes, and what you leave behind. Sense AI, the AI assistant in the SuperMoney app, can talk through tradeoffs like this with your actual budget and account balances in view.
A reverse mortgage is the right tool for some retirements and an expensive mistake in others, and the deciding factor is usually how long you stay. If a monthly payment is manageable, comparing HELOC offers first shows what the cheaper alternative gets you before you commit to HECM costs.
