HEA Loan Calculator
HEA stands for home equity agreement, and despite this page’s slug it is not a loan: an investor pays you a lump sum today and takes a share of your home’s future value at settlement instead of interest and monthly payments. Enter your home value, the investment amount and the share you are being offered to see the projected future value, the repayment under the structure you pick, the effective annual rate you can hold next to a loan quote, and what you keep after settling.
Repayment due at settlement
$0
Estimate only. Real agreements vary: some share downside if the home loses value, some floor the repayment; fees and early-buyout terms differ by provider. Read the contract, not just the calculator.
Quick Answer
On a $500,000 home growing at 4% a year for 10 years, a $50,000 home equity agreement with a 3% fee puts $48,500 in your account and settles against a projected value of $740,122. Structure A (10% of future value) repays $74,012, an effective 4.00% a year, and you keep $666,110. Structure B ($50,000 plus 20% of appreciation) repays $98,024, an effective 6.96% a year. Same home, same cash, a $24,012 difference: the structure matters more than the headline amount. The calculator above is pre-filled with the structure A run.
Key takeaways
- An HEA is not a loan. No interest, no monthly payments, no debt on your credit report, but a lien on the property and a lump-sum settlement at exit.
- The two repayment structures are different products wearing one name. Always price both before comparing providers.
- The effective annual rate is the only honest comparison tool: it converts a share of future value into a rate you can set beside a HELOC or home equity loan quote, the same comparison the Consumer Financial Protection Bureau’s Issue Spotlight on home equity contracts makes.
- Appreciation is the bet. The faster your home grows, the more expensive this money becomes; in a falling market the investor can end up sharing your loss.

How to use the HEA calculator
Enter the deal you have been offered, pick its repayment structure, and read the repayment, the total cost and the effective rate together. Results stay hidden until you click Calculate.
- Home value and investment: today’s value and the lump sum offered. The tool refuses an investment at or above the home value, which no real HEA approaches: offers normally run 5% to 20% of value.
- Structure and share: choose A or B to match your contract, then enter the share exactly as quoted. Switching structure relabels the share field, because a share of future value and a share of appreciation are different promises. The tool prices one structure per run, so run it twice to compare A against B.
- Appreciation: your honest guess, not the provider’s brochure number. Try a low guess as well: at 0% or negative appreciation the ranking of HEA versus loan flips.
- Term: years until you expect to settle. Longer terms compound the future value and usually raise the repayment faster than they raise a loan balance.
- Fee: the origination percentage deducted at closing. Blank counts as 3%. The cash-received line nets the fee out; the total cost line counts it.
If a monthly payment is affordable, price the loan alternative honestly before signing away appreciation: the mortgage payment calculator shows what a conventional loan costs month by month, and a home equity loan is the closest like-for-like rival to an HEA.
The two HEA structures, priced on the same home
Structure A sells a slice of the whole future value; structure B sells the original money back plus a slice of the growth. On identical inputs they settle very differently.
Structure A repayment = Share% × Future value
Structure B repayment = Investment + Share% × (Future value − Home value)
Cash received = Investment × (1 − fee ÷ 100)
Total cost = Repayment − Cash received
Effective annual rate = (Repayment ÷ Investment)1 ÷ term − 1
| Run (all verified in the tool) | Repayment | Total cost | Effective rate | You keep |
|---|---|---|---|---|
| Worked example A: 10% of future value, 4% growth, 10 years | $74,012 | $25,512 | 4.00% | $666,110 |
| Same deal as B: principal + 20% of appreciation | $98,024 | $49,524 | 6.96% | $642,098 |
| B in a falling market: 5% yearly depreciation, 20% share | $9,874 | -$38,626 | -14.97% | $289,495 |
| A in the same falling market: 10% of future value | $29,937 | -$18,563 | -5.00% | $269,432 |
Neither structure is a hybrid of the other. If a provider or a rival calculator ever shows a repayment that adds a percentage of the full future value on top of the returned principal, that formula matches no real agreement structure documented by providers or regulators, and the number should not be trusted.
The effective rate, and one honest limitation of this tool
The effective annual rate is the rate that compounds the headline investment into the repayment over the term, which makes an interest-free product comparable with interest-bearing ones. It is how the CFPB compared a $50,000 HEA with a $50,000 HELOC at 9% over 10 years in 2025: the HELOC cost about $95,000 in total, the HEA between $94,000 and $216,000 depending on appreciation, cheaper only when the home lost value.
One limitation, stated plainly because the earlier version of this page got it wrong: this tool computes the effective rate from the headline investment ($50,000), not from the net cash you actually receive after the fee ($48,500). Measured against the cash in your account, the true yearly cost of the worked example is a little higher than the 4.00% and 6.96% shown: roughly 4.3% and 7.3% respectively. The fee is not hidden: it is netted out of the cash-received line and counted in the total cost line. But if you compare this rate against a loan APR, nudge it upward slightly in your head, because loan APRs are legally required to fold their fees in. Consumer rules for the loan side of that comparison sit in the CFPB’s Regulation Z open-end credit rules, and its Owning a Home loan options guide walks through how HELOCs and home equity loans disclose their costs.
Fees, settlement and the exit plan you need before signing
Settlement is a lump sum, and it arrives on the investor’s schedule as much as yours: when you sell, when you refinance, when you buy out early, or when the term ends, usually 10 to 30 years out.
Fees come off the top at closing: typically 3% to 5% of the investment as an origination or processing fee, plus appraisal, title and filing costs that this calculator does not model. If your exit is a refinance, price that too: the cost to refinance a mortgage calculator shows what the refinance itself will charge, and the investor’s lien usually has to be settled or restructured before a new lender will close. Homeowners weighing the loan route against an agreement should also read the CFPB’s guide to conventional loan options for how the regulated products present the same money.
Where an HEA genuinely helps
- No monthly payment at all, which suits irregular income
- Approval leans on equity rather than credit score or income documentation
- In a flat or falling market the investor shares the downside (structure-dependent)
- Usually no prepayment penalty on an early buyout
Where it can hurt
- In a hot market the cost can run to roughly double a HELOC’s, per the CFPB modelling
- A lump-sum exit with no payment history behind it forces a sale, a refinance, or savings
- The lien complicates refinancing and some future borrowing, much like a second mortgage would
- Contract terms (floors, caps, valuation method) vary by provider and are easy to misread
Edge cases this tool handles honestly, and one it does not
Three behaviours are worth knowing before you trust any single run. First, a 0% share in structure A returns a $0 repayment and a -100.00% effective rate, and the verdict line still says the home lost value even when it gained: the verdict keys off the negative rate, not the market, so read a 0% share as the degenerate input it is. Second, a negative total cost is real output, not an error: it means the repayment came in under the cash you received, which is exactly what happens when the investor shares a loss. Third, the tool has no floor: push structure B to a 100% share with steep depreciation (a $500,000 home falling 20% a year for 10 years) and the raw formula returns a negative repayment of -$396,313 and an effective rate of NaN%. No real contract would pay you to settle; providers floor repayments or cap the shared loss. Treat extreme-depreciation structure B runs as directional, and rely on your contract’s downside clause for the real number.
What competing calculators miss
The HEA calculator field is thin, and most of what ranks is explanation without arithmetic:
- OwnCalculator’s HEA calculator: the one dedicated rival tool. It prices a single structure (investment plus a share of appreciation) from home value and mortgage balance, with no future-value percentage structure and no conversion of the cost into a comparable annual rate.
- Finder and SuperMoney guides: thorough explainers with the CFPB cost comparison, provider lists and worked examples in prose, but no calculator a reader can run on their own offer.
- Home Equity Appreciation (provider content): good structure education and an honest three-market table, but it is a provider’s funnel: the concrete numbers sit behind an estimate request.
- APR Finder: eligibility and provider comparisons, no repayment math.
- The gap this page fills: both real repayment structures in one tool, an effective annual rate beside every run, net-of-fee cash and a you-keep line, falling-market runs that show the investor sharing a loss, and open disclosure of the rate’s fee limitation and the missing repayment floor.
Frequently asked questions
A home equity agreement is a contract, not a loan: an investor pays you a lump sum, typically 5% to 20% of your home’s value, with no interest and no monthly payments, and at settlement you repay a share of the home’s future value or the original amount plus a share of its appreciation, depending on the structure you signed.
No. An HEA is a shared-equity contract rather than debt, so it generally does not appear as a loan on your credit report or count in your debt-to-income ratio. The investor does place a lien on the property, which is why the slug of this page says loan but the contract itself is not one.
One of two ways, and this calculator models both. Structure A repays a fixed percentage of the home’s future value: 10% of $740,122 is $74,012. Structure B repays the original investment plus a share of the appreciation: $50,000 plus 20% of a $240,122 gain is $98,024. Run both structures on your own numbers before comparing offers.
There is no interest, but there is a real cost: an origination fee of roughly 3% to 5% of the investment, deducted from your funding, plus the share of appreciation you give up. In the worked example the total cost is $25,512 under structure A and $49,524 under structure B, on $48,500 of cash actually received.
It converts the repayment into the yearly rate that would turn the headline investment into that repayment over the term: (repayment divided by investment) to the power of 1 over term, minus 1. One caution, stated openly: this tool computes the rate from the $50,000 headline investment, not from the $48,500 you keep after the fee, so the rate against cash actually received would be slightly higher.
Sometimes, and mainly when the home disappoints. A 2025 CFPB analysis modelled a $50,000 HEA costing $94,000 to $216,000 over 10 years against $95,000 for a $50,000 HELOC at 9%, and the HEA came out cheaper only when the home lost value. Run your own appreciation guess through both structures before deciding.
It depends on the structure and the contract. In this tool’s structure B, a 5% yearly fall over 10 years cuts the repayment on a $50,000 agreement to $9,874, because the investor shares the loss; structure A repays 10% of whatever the home is worth, $29,937 in the same scenario. Some real contracts floor the repayment instead, so check your downside clause.
Most providers allow an early buyout, usually without a prepayment penalty, priced from the home’s value at exit. Settlement also falls due when you sell, refinance, or reach the end of the term, typically 10 to 30 years, and the investor’s lien usually has to be cleared before a refinance can close.
