How the Reverse Mortgage Calculator Works

This calculator uses the HUD HECM principal limit factor (PLF) methodology. The PLF depends on the age of the youngest borrower and the expected interest rate. A higher age or lower rate produces a higher PLF, meaning more borrowing power.

Max Claim Amount = MIN(Home Value, $1,149,825)
Principal Limit = PLF(age, rate) × Max Claim Amount
Upfront MIP = 2% × Max Claim Amount
Origination Fee = MAX($2,500, MIN(2% × Home Value, $6,000))
Net Proceeds = Principal Limit − Mortgage Balance − Total Costs
Monthly Tenure = PMT(net principal, rate/12, life months)

Who Is This Calculator For?

Check how much equity you could access without selling your home or making monthly payments.

Retirement income planners

Compare lump sum, monthly tenure, and line of credit options against other retirement income sources.

How to Use the Calculator

1
Enter home appraised value
Use the current market value or a recent appraisal. The HECM uses the lesser of the appraised value and the $1,149,825 FHA lending limit.
2
Enter the age of the youngest borrower
Both spouses must be at least 62. Use the younger age for the calculation because PLF is based on the person with the longer expected tenure in the home.
3
Enter the expected interest rate
Use the current HECM expected rate, which is typically the 10-year LIBOR swap rate plus a margin. Check with a lender for current rates; the default of 6.5% is approximate for 2025.
4
Enter any existing mortgage balance
If you have a forward mortgage, it must be paid off at closing using reverse mortgage proceeds. Enter your current payoff balance.
5
Choose payout type
Lump sum shows the one-time net cash available. Monthly Tenure shows the estimated monthly check for as long as you live in the home. Line of Credit shows the initial credit line amount.
6
Review the results
The results show principal limit, cost breakdown, and net proceeds or monthly payment. All figures are estimates. Contact a HUD-approved lender for exact numbers.

Worked Example: Carol, Age 73, $500,000 Home

Carol owns a $500,000 home outright, is 73 years old, and wants to estimate a HECM with a 6.5% expected rate.

Home value$500,000
Max claim = min($500k, $1,149,825)$500,000
PLF at age 73 (6.5% rate) ≈ 0.558 + adj≈ 0.585
Principal limit (0.585 × $500,000)$292,500
Upfront MIP (2% × $500,000)-$10,000
Origination fee (2% × $500k, capped)-$6,000
Third-party closing costs (est.)-$3,500
Net lump sum proceeds$273,000

Common Mistakes

Assuming no ongoing obligations

A reverse mortgage does not eliminate homeownership costs. Property taxes, homeowners insurance, and maintenance remain your responsibility. Defaulting on these can trigger foreclosure.

Confusing principal limit with cash in hand

The principal limit is the gross amount you can borrow. Upfront costs (MIP, origination, closing) typically reduce your net proceeds by $15,000 to $25,000 on a $400,000 home.

Not accounting for an existing mortgage

If you have a remaining mortgage balance, it must be paid off at closing using reverse mortgage funds. This directly reduces the cash you receive.

Overestimating proceeds on very high-value homes

The HECM is capped at a $1,149,825 claim amount. A $2 million home gets the same principal limit calculation as a $1.15 million home under HECM rules.

Skipping HUD-required counseling

Before any HECM application, federal law requires counseling with a HUD-approved counselor. This is not optional. The counselor reviews your situation and alternative options.

Pro Tip

Waiting from 62 to 70 increases the PLF from about 0.41 to 0.52, a 27% increase in borrowing power. On a $500,000 home, that is approximately $55,000 more available equity. If you do not need the funds immediately, delaying entry can significantly increase the loan amount.
