How a HECM turns home value into cash, step by step
A Home Equity Conversion Mortgage (HECM) is the FHA-insured reverse mortgage for homeowners 62 and older. Unlike a conventional home equity borrowing estimate, the amount is set by age and a federal formula, and no monthly payment is required. This calculator follows HUD's sequence:
- Maximum claim amount. The lesser of your appraised value and the FHA HECM limit ($1,249,125 for 2026). A $2 million home is treated as a $1,249,125 home.
- Initial principal limit. The maximum claim amount times the principal limit factor for the youngest borrower's age and the expected rate.
- Mandatory obligations. Your existing mortgage payoff, the 2% upfront mortgage insurance premium, the origination fee and closing costs are paid first.
- First-year cap. You can draw the greater of 60% of the principal limit or your obligations plus 10% of the principal limit in year one.
- Net proceeds. The capped amount minus the mandatory obligations is the cash you actually receive at closing.
For the default inputs (a $450,000 home, a $100,000 mortgage, age 70, 6% expected rate), HUD's factor is 0.415, so the principal limit is $186,750. Mandatory obligations are $118,500, which is more than 60% of the principal limit, so the first-year cap is $118,500 plus 10% of the principal limit, or $137,175. Net cash at closing is about $18,700, with another $49,600 or so available as a line of credit after the first year on an adjustable-rate HECM.
