HECM Reverse Mortgage Calculator 2026
Enter your age, your home's value, and current expected interest rate. The calculator returns your estimated principal limit (how much you can borrow), line-of-credit growth projections at years 5, 10, 20, and 30, and your monthly tenure payment. If your home value exceeds the 2026 HECM lending limit of $1,249,125, it also shows a jumbo reverse mortgage comparison. No email or phone required.
Your inputs
Age of the youngest borrower on title. HECM requires 62+. Some jumbo products allow 55+.
Current market value of the home. HECM caps at $1,249,125 in 2026; jumbo lends against full value up to ~$4M.
Approximate current HECM expected rate. Lower rate = higher principal limit. Rates change daily.
If you have a remaining mortgage, HECM pays it off first. Remaining principal limit is available to you.
Your estimate
Growing line of credit projection
| Year | Available LOC |
|---|
LOC grows at note rate + 0.5% MIP annually. Set up early, don't draw, and reserves grow substantially.
Estimates use realistic 2026 HUD Principal Limit Factor tables and are typically within 5-10% of an actual quote. Actual numbers depend on the specific expected rate on lock day and wholesale lender pricing.

How this calculator works
Three variables drive your HECM principal limit:
- Your age. Specifically, the age of the youngest borrower on title. HUD publishes a Principal Limit Factor (PLF) table indexed by age. Older = higher PLF (more borrowing capacity per dollar of home value).
- Your home's appraised value. Capped at the 2026 HECM lending limit of $1,249,125. Homes above that use a jumbo reverse mortgage that lends against the full appraised value.
- Current expected interest rate. HUD's PLF table adjusts by rate too — lower rate produces higher PLF.
The formula: Principal Limit = min(Home Value, $1,249,125) × PLF, where PLF is the HUD-published percentage based on your age and rate.
Line of credit growth explained
The HECM line of credit is one of the most valuable features in reverse mortgage products. Your unused available credit grows each year at the note rate plus the annual FHA mortgage insurance premium (0.5%). Compounded.
Example: a 62-year-old opens a HECM with a $200,000 line of credit at a 6.5% note rate. Never touches it. By age 80 (18 years later), the available credit has grown at 7% compounded to approximately $677,000. That growth happens whether or not the borrower ever draws from the line.
This is why financial planners increasingly recommend HECM LOC as a "buffer asset" — a growing reserve that sits in the background as insurance against future medical, care, or market-sequence risk. See our blog post: Why the HECM Line of Credit Grows Over Time.
Monthly tenure payment explained
The tenure payment option converts your principal limit into a guaranteed monthly income for as long as at least one borrower lives in the home as their primary residence. The calculation is based on HUD's actuarial life-expectancy tables from your age to age 100 — older borrowers get higher monthly payments because the payment period is shorter.
Tenure payments are not taxable (they're treated as loan proceeds, not income), which makes them particularly efficient in higher-tax states.
HECM vs jumbo — when to consider each
For homes valued above $1,249,125, HECM caps your borrowing base at the lending limit. A jumbo (proprietary) reverse mortgage lends against the full appraised value up to approximately $4M with some programs going higher. Jumbo trade-offs:
- Higher absolute borrowing power (bigger dollar amount available)
- Slightly lower PLF (percentage) than HECM at the same age/rate
- No FHA mortgage insurance premium (saves cost)
- No growing line-of-credit feature (this is HECM-exclusive)
- Some programs available at age 55+
