About Reverse Mortgage Calculator

The Reverse Mortgage Calculator estimates how much cash a homeowner aged 62 or older could receive from a HUD-insured Home Equity Conversion Mortgage (HECM). Most online estimators give you a single dollar figure and stop there. This tool walks you through every gate the lender's underwriter walks through — the FHA lending limit cap, the age-and-rate Principal Limit Factor lookup, the initial mortgage insurance premium, the origination fee schedule, and any existing mortgage payoff — so you can see exactly where your home's value goes and which lever moves the result.

What makes this calculator different

Real HUD PLF approximation

We model the HUD Principal Limit Factor table using a closed-form approximation tuned against the published 2024 grid. Most calculators use a flat percentage — ours moves with both age and rate, like the real underwriting does.

Funds-cascade visual

An animated waterfall shows your home value falling through each HUD rule — MCA cap, PLF, mortgage payoff, MIP, origination, closing costs — until what's left is the cash you actually pocket.

Four payout options compared

Same net principal, shown as a lump sum, monthly tenure for life, fixed-term monthly, and a growing line-of-credit balance at years 5 and 10. Pick the shape that fits your plan.

10-year projection with non-recourse floor

The chart compounds your loan balance and appreciates the home so you can see equity over time — and it visually highlights the non-recourse protection that caps what you ever owe at the home's value.

Age sensitivity bars

A grouped bar chart shows how your net proceeds would change at every other age. Older borrowers get materially more, and waiting two or three years can sometimes unlock tens of thousands.

Honest closing-cost itemization

HUD's exact origination fee schedule (2% of first $200k + 1% of remainder, capped $2.5k–$6k), 2% initial MIP on MCA, and any servicing set-aside — separated, not blended into one mystery number.

How to use the Reverse Mortgage Calculator

Pick a quick example — modest home at age 70, typical retiree at 75, high-value home at 80, or a paid-off home at 65 — to populate every field with a realistic scenario, or enter your own numbers from scratch.
In the borrower pane, enter your age (must be at least 62 to qualify) and your spouse's age if applicable. HUD uses the youngest qualifying age for the PLF lookup, so an under-62 spouse can lower your proceeds.
In the property & loan pane, enter the home's appraised value, any existing mortgage balance that must be paid off at closing, and the expected interest rate the lender quoted you.
Optionally override the auto-calculated origination fee, change other closing costs, or add a servicing set-aside if your lender requires one. Leave the term-payout box at 0 to use the lifetime tenure formula.
Click "Calculate." The headline shows your net proceeds, the funds-cascade chart visualizes every deduction, and the payout-options grid shows the same money in four different shapes. Scroll down for the 10-year projection and the step-by-step formula breakdown.

The math under the hood

Every HECM calculation starts with the Maximum Claim Amount:

$ \text{MCA} = \min(\text{Appraised Value},\ \text{FHA HECM Limit}) $

The 2026 FHA HECM lending limit is $1,209,750. Above that, the loan calculation is capped — but you may qualify for a private "jumbo" reverse mortgage that uses the appraised value directly.

The Principal Limit is the MCA multiplied by HUD's age-and-rate Principal Limit Factor:

$ \text{Principal Limit} = \text{MCA} \times \text{PLF}(\text{age},\ \text{rate}) $

HUD's exact PLF table is built by solving the lifetime cash-flow equation under a 105% mortality survival curve and the expected rate plus 0.5% MIP. We fit a linear approximation against the published HUD grid:

$ \text{PLF}(a, r) \approx 0.50 + 0.007 \cdot (a - 62) - 0.04 \cdot \max(0,\ r - 3) $

The expected rate is floored at 3% per HUD rule. The approximation matches the published table within roughly 5 percentage points across age 62–95 and rates 3–10%.

Tenure (lifetime) monthly payments use HUD's annuity formula assuming the youngest borrower lives to 100:

$ \text{PMT}_{\text{tenure}} = \dfrac{\text{NP} \cdot i}{(1+i) - (1+i)^{-n}} \quad \text{where } n = (100 - \text{age}) \times 12 $

Term-payment uses the standard fixed-term annuity formula. Line-of-credit growth follows the HUD rule that the unused balance grows at the expected rate plus the 0.5% annual MIP:

$ \text{LOC}_t = \text{NP} \cdot \left(1 + \dfrac{r + 0.5\%}{12}\right)^{12t} $

Payout options at a glance

Option	Cash flow shape	Best for
Lump sum	One payment at closing	Paying off existing mortgage, large medical or home-modification costs
Tenure	Equal monthly for life (while you live in the home)	Steady income supplement; eliminates longevity risk
Term	Higher monthly for a fixed number of months, then stops	Bridging until Social Security or pension begins
Line of credit	Draw as needed; unused balance grows monthly	Retirement risk hedge; the growing credit line is often the most powerful long-term option

Frequently Asked Questions

What is the Principal Limit Factor and why does it matter?

The Principal Limit Factor (PLF) is the percentage of your Maximum Claim Amount that HUD allows the lender to advance you. It is published in a table by the youngest borrower's age and the expected interest rate. Older borrowers and lower rates produce higher PLFs, which is why proceeds grow as you age.

Why does the calculator use the youngest borrower's age?

HUD requires the PLF lookup to use the youngest co-borrower or qualifying non-borrowing spouse, because the loan must be sustainable over the longest expected lifetime in the household. If you have a 75-year-old borrower and a 65-year-old spouse, the PLF for age 65 is used.

What is the Maximum Claim Amount?

The MCA is the smaller of your home's appraised value and the FHA HECM lending limit. The 2026 limit is $1,209,750. Homes worth more than that can still qualify for HECM, but the calculation only uses the limit. Above-limit value can be tapped via a private jumbo reverse mortgage.

How is the origination fee calculated?

HUD allows a fee equal to 2% of the first $200,000 of MCA plus 1% of any amount above that, capped at $6,000 and floored at $2,500. You can override the auto-calculated value if your lender quotes a different number.

What is the difference between tenure, term, and line of credit?

Tenure pays a fixed monthly amount for as long as you live in the home, calculated assuming you live to age 100. Term pays a higher fixed monthly amount for a chosen number of months, then stops. Line of credit lets you draw funds as needed and the unused balance grows at the expected rate plus the annual MIP, often making it the most powerful long-term option.

What does non-recourse mean for a reverse mortgage?

HECM loans are non-recourse, meaning you and your heirs will never owe more than the home is worth when it is sold. If the loan balance compounds past the home value, the FHA mortgage insurance covers the shortfall, not you. The 10-year projection chart in the result shows this floor in action.

Are reverse mortgage proceeds taxable?

Reverse mortgage proceeds are loan advances, not income, so they are generally not taxable and usually do not affect Social Security or Medicare benefits. They can affect needs-based programs like Medicaid or SSI if the funds are not spent in the same month they are received.

Will I lose my home with a reverse mortgage?

You keep title to your home throughout the life of the loan. The loan only becomes due when the last borrower no longer occupies the home as their principal residence — typically due to a permanent move, sale, or death. As long as you keep up with property taxes, insurance, and basic maintenance, you cannot be forced out.
