Home Equity Investment Calculator: Estimate Your Settlement Payment and Annual Cost

Summary:

A home equity investment gives you cash today in exchange for a share of your home’s future value, with no monthly payment. Because you won’t know the cost until you settle, the calculator lets you set the appreciation rate and exit year and shows the settlement payment and annual cost for each scenario. Compare providers on the standard annual cost, but compare an HEI against a loan on the after-fees figure. Run at least three appreciation rates and one downturn before you sign.

Home equity investment offers are built to be as simple as possible. Cash now, no monthly payment, no interest rate. However, calculating the actual cost of an HEI is not always that simple. The price depends on multiple factors, such as your home’s future value, so the real cost doesn’t appear anywhere on the offer. Plug your terms into the calculator below and see what you’d actually pay under different scenarios, from a hot market to a flat one to a downturn.

What This Calculator Does

A home equity investment (HEI) gives you a lump sum today in exchange for a share of your home’s future value. No monthly payments. No interest rate. No principal balance. You make one settlement payment, due when you sell, when you buy the agreement out, or at the end of the maximum term. Most agreements run 10 to 30 years, and most let you settle any time before the term expires without a prepayment penalty. If your provider calls it a home equity agreement, a shared equity product, or something else, see our guide to home equity investment companies; the calculator handles every structure we know of.

That payment depends on what your home is worth the day you settle, and on when that day turns out to be. So here’s the uncomfortable part: you can’t know what an HEI costs when you sign it. There’s no single percentage that describes it the way an APR describes a mortgage. What the calculator does instead is let you set the assumptions yourself and see what the agreement would cost under each one.

For every scenario you enter, it shows your future home value, the estimated settlement payment, and the annual cost. Annual cost is the industry’s standard measure: the settlement payment expressed as an annualized percentage of the amount invested, compounded annually, and calculated before fees. The calculator also plots that cost against typical rates for a HELOC, a home equity loan, and a personal loan, so you can see where the agreement sits next to borrowing.

How to Use It

1. Pick your product type

Start here, because everything else depends on it. Appreciation share agreements return the amount invested plus a share of your home’s growth above an adjusted starting home value. Total value share agreements take a share of your home’s full future value instead. The input fields change to match.

2. Enter your deal terms

Home value and investment amount come straight off your offer. For appreciation-share agreements you’ll also enter the adjusted starting home value. That’s the figure the provider measures growth from: your appraisal, reduced by a risk adjustment. The provider sets it, not you, and the bigger the adjustment, the sooner the provider’s share starts to build. Use the exact figure from your paperwork, not the default.

3. Check the cost cap

Nearly all providers apply an annual cost cap, which limits the settlement payment no matter how much your home appreciates. The calculator assumes a 20% cap by default, because that’s where most providers sit, and draws it on the chart as a ceiling.^[1] Enter a different figure if your agreement uses one, or switch the cap off if yours has none. The cap does most of its work right where people are most likely to land: the early years, and fast-appreciating markets. Appreciation-share agreements often carry a payout cap too, limiting the settlement to a multiple of the amount invested. Total value share agreements generally don’t. Where both apply, the lower settlement payment wins.

4. Choose an appreciation rate

This is the assumption that moves the answer most. Stress-test it. The 4.3% default is where the two main national house price indexes land over the past 35 years: from January 1991 to May 2026, the Case-Shiller national index averaged 4.31% a year and the FHFA purchase-only index 4.30%.^[2][3] Shorter windows look very different, roughly 3% a year over the past 20 years and 6.5% over the past 10. And recent forecasts for the next few years sit below all of these.^[4] Run 3%, 4.3%, and 6% at minimum. Then try a negative rate, so you know what a downturn does.

5. Vary the exit year

Most homeowners settle well before the end of the maximum term. Treat the term on your agreement as a ceiling, not a prediction. Move the exit year around and watch both numbers. In a rising market, settling later usually means a larger settlement payment but a lower annual cost, because the same cost gets spread over more years. Settling sooner does the reverse. The exit-year table below the results shows this directly.

How to Read the Results

Three figures do most of the work:

Settlement payment: the dollar amount you’d owe at settlement. This is what actually leaves your equity.
Annual cost: the settlement payment as an annualized percentage of the amount invested. You’ll see it twice, before and after fees, and the gap between them matters (more on that below).
Future home value: what your assumptions say your home is worth on the settlement date. Give it a sanity check. If it looks implausible, your appreciation rate probably is too.

Two Cost Figures, and Which One Is the Standard

Annual cost is the industry standard. Providers all calculate it the same way: divide the settlement payment by the amount invested and annualize it with annual compounding. It’s deliberately calculated before origination fees and closing costs. Use this figure when you put one provider’s disclosure next to another’s, because it’s the one they all publish.

The second figure is the same calculation after fees. It isn’t an industry measure, and providers don’t publish it. Origination fees typically run about 4% to 5% of the amount invested, third-party costs like appraisal, title, and escrow come on top, and all of it comes out of your proceeds at closing.^[1] So the cash you actually receive costs more than the standard figure shows.

Each number has its job. Compare providers with each other on annual cost. Compare an HEI against a loan on the after-fees figure. A loan’s APR is required by law to include origination fees, so setting it against a cost figure that leaves them out isn’t a fair fight.^[5]

How the Industry Calculates Annual Cost

With no monthly payments, no interest rate, and no principal balance, the arithmetic is simpler than a loan’s. Every figure the calculator shows comes from these steps, and you can check them by hand.

Future home value = current home value × (1 + appreciation or depreciation rate) ^ years

Gross proceeds = the gross amount invested by your provider, before origination fees and closing costs are deducted

For an appreciation share agreement:

Share-based amount = gross proceeds + share % × (future home value − adjusted starting home value)

For a total value share agreement:

Share-based amount = share % × future home value

For both structures:

Capped amount = gross proceeds × (1 + effective annual cap) ^ years

Settlement payment = the lesser of the share-based amount and the capped amount

Annual cost = (settlement payment ÷ gross proceeds) ^ (1 ÷ years) − 1

Two details are easy to miss. First, the cap applies to the gross amount invested, not to what you receive after fees. A 20% cap limits the provider’s return, not your cost of funds. Second, because the settlement payment is the lesser of the two amounts, the cap only changes the answer when the share-based figure would have been higher. In practice that means strong appreciation, an early settlement, or both.

Comparing an HEI With a HELOC, Home Equity Loan, or Personal Loan

Expand the comparison panel and enter the terms of any offers you’re weighing. The chart plots annual cost, the industry-standard figure, and the after-fees figure shows up in the results and the exit-year table. Everything sits on the same axis so you can see the costs side by side. The reference rates it starts with are national averages, not quotes. Your own rate depends on your credit, your equity, and the lender.

	Monthly payment	Cost known up front?	Qualification
Home equity investment	None during the term	No. Depends on future home value and settlement date	Based mainly on equity and the property; income documentation not typically required
HELOC	Required during draw and repayment	Partly. The rate is variable, and your balance depends on what you draw	Income tests and credit score standards apply
Home equity loan	Fixed, consistent through the term	Yes. Total interest is knowable at signing	Income tests and credit score standards apply
Personal loan	Fixed, consistent through the term	Yes. APR is disclosed and includes origination fees	Credit-driven; no home equity required and no lien on your home

Early Exit Raises the Cost of Every Option

Most comparisons miss this. A quoted interest rate assumes you hold the loan to term. You pay closing costs and origination fees up front, then earn them back over the life of the agreement. Pay off early and the same fixed cost gets spread over fewer years, which pushes the effective cost up.

The chart shows this clearly for the HEI. Its cost line is steep in the early years and falls as the term lengthens, because the entire cost is deferred to a single payment at the end. Where the cap binds, the ceiling holds that early part of the line down, not your deal terms. That’s why the cap matters most if there’s any chance you’ll settle in the first few years.

The HELOC, home equity loan, and personal loan show up as flat lines at their quoted rates. Read those as best cases, not what you’d actually pay if you exit early. A home equity loan with closing costs is measurably more expensive paid off in year two than in year ten. Many HELOCs waive closing costs but claw them back with an early-termination fee if you close the line in the first two or three years. A personal loan with an origination fee works the same way. If you expect to settle early, the real gap between the options is narrower than those flat lines suggest.

Why the Comparison Is Never Apples-to-Apples

Annual cost is a useful way to line an HEI up against a loan. But the two aren’t the same kind of measurement, and a direct comparison will always be a little off:

No monthly payment is a valuable perk an annual percentage does not capture. For a lot of homeowners, that’s the whole reason to consider an HEI. What it’s worth depends on your circumstances and what you’d do with the money.
The HEI number moves; the loan numbers mostly don’t. Annual cost swings with settlement timing and home values, so don’t treat any single result as a forecast. A fixed loan’s APR is a disclosure. Annual cost is an estimate built on your assumptions.
Dollar cost and annual cost point in opposite directions. On an HEI, the scenario with the lowest annual cost is often the one with the biggest settlement payment. Look at both before you decide which scenario you like.
A HELOC’s rate can move too. It’s more predictable than an HEI, but variable still means not fixed.

WEIGH THE RISKS AND BENEFITS OF A HOME EQUITY INVESTMENT

Here is a list of the benefits and the drawbacks to consider.

What the Calculator Can’t Tell You

It gives you a financial comparison, not a recommendation. Its biggest limitation is built into the product itself. Run as many scenarios as you like, and you still can’t predict future home values with any confidence, or the life events that’ll decide when you settle. That uncertainty comes with an equity-based product. Get comfortable with it before you sign, not after.

It also can’t price what you give up. If your home appreciates strongly, the provider’s share at settlement gets bigger. Your own equity grows too, but you’ll likely have less of it to work with later, for a move, for retirement, or to leave to your kids. Weigh that against what the money solves for you now.

And it can’t value the thing many homeowners care about most. What’s it worth to wipe out a pile of high-rate credit card debt, or pay for a child’s education, without adding another monthly payment? Only you can put a number on that. It belongs in the decision right alongside the cost.

Frequently Asked Questions

Why do you show two cost figures?

Annual cost is the industry standard and leaves out origination fees and closing costs, so it’s the right figure for comparing one provider’s disclosure with another’s. The after-fees figure is our own addition. Fees come out of your proceeds at closing, so the money you actually receive costs more than the standard figure shows. It’s also the fairer number to set against a loan, because a loan’s APR already includes origination fees.

Is annual cost the same as an APR?

No. An APR is a Truth in Lending Act (TILA) disclosure, and providers don’t treat these agreements as credit, so you won’t find a TILA APR on the paperwork. Annual cost is the industry’s own measure, calculated before origination fees and closing costs. Some states now require an annualized cost figure in the disclosure itself.^[6][7] Illinois, for example, requires one calculated with the same method federal rules use for an APR, so it may not match a provider’s own annual cost number.

Is a home equity investment a loan?

Depends on who you ask, and both sides have a real argument.

The industry’s case is that an HEI isn’t debt. There’s no interest rate, no monthly payment, and no fixed amount you owe. The provider is buying a stake in your home’s future value, and it shares the risk that the value falls. If your home drops far enough, the provider can get back less than it put in. That’s how an investment behaves, not a loan, and it’s why providers don’t give you an APR.

The CFPB sees it differently. In a January 2025 brief filed in a federal court case, the Bureau argued these contracts meet the legal definition of credit under TILA anyway. You get money now, you’re obligated to pay later, and the pricing makes it very likely the provider comes out ahead. In the case it weighed in on, the homeowner received 44% of her home’s value and owed 70% of it at settlement. By the CFPB’s math, the company would get its money back unless the home lost more than 39% of its value, a drop the Bureau called unprecedented.^[8]

So who’s right? It isn’t settled. That brief laid out the Bureau’s position under its leadership at the time. It isn’t a regulation, and no federal rule has resolved the question. Some states have stopped waiting: Connecticut, Maryland, Washington, and Illinois now regulate these contracts under their mortgage lending laws.^[9][6] Either way, the practical point for you is the same. There’s no APR on the paperwork, so run the scenarios yourself.

What appreciation rate should I use?

Start at 4.3%, then test 3% and 6% to see the range. If homes in your metro usually appreciate faster than the national average, lean toward the higher scenario when you evaluate the offer, because faster appreciation means a bigger settlement payment. Recent forecasts for the next few years are below the long-run average, so run a conservative case too.

How accurate is the estimate?

As accurate as your inputs. Your deal terms (amount, share percentage, adjusted starting home value, term, and caps) are fixed by your contract. The only real unknowns are what your home will be worth at settlement and when you’ll actually settle. That’s why testing several appreciation rates and exit years matters more than any single result.

Why does the annual cost fall the longer I hold the agreement?

Because the cost is spread over more years. In a rising market, a longer hold means a bigger settlement payment in dollars, but spreading that cost across more time lowers the annualized percentage. Exit early and you get the reverse: a smaller dollar cost, a higher annual cost. Both numbers are real. They just answer different questions.

Compare home equity investment providers once you know roughly what an agreement would cost you.

For educational purposes only. Results are estimates based on the inputs provided. Actual terms, settlement payments, and costs vary by provider. Future home values depend on market conditions. Reference rates for HELOCs, home equity loans, and personal loans are national averages, not quotes.

Key takeaways

Home equity investments are built differently from HELOCs and home equity loans. Each has real advantages and drawbacks, and which one fits depends on your situation.
HEI cost comes as a set of estimated settlement payments under different assumptions, each with an annual cost percentage. HELOC and home equity loan cost comes as a single APR. You can compare them in general terms, but not like for like.
On a $500,000 home, a $50,000 total value share agreement at 18% of future value works out to about 10.6% annual cost over 10 years at 4.3% appreciation. An appreciation-share agreement taking 25% of growth above a starting value set at 75% of today’s appraisal comes to about 11.4% on the same assumptions.
The two main national house price indexes both average about 4.3% a year over the past 35 years, but shorter windows differ a lot and recent forecasts are lower.
Origination fees and closing costs come out of the gross investment at closing, so you receive less cash than the amount the annual cost figure is calculated on.
Most providers apply a 20% annual cost cap. It protects you most in the early years of the contract and when home prices rise fast.
