How these products work

Home equity investments (Point, Unlock, etc.) give you cash today in exchange for a share of your home's future appreciation. No monthly payments, no interest — but you pay more at exit if your home appreciates.

Compare the effective annual cost to a HELOC or home equity loan rate. Cheaper than a HELOC if appreciation is slow; more expensive if appreciation is fast. Also note many have termination fees, minimum payoff requirements, and can force a sale at expiration.

How this calculator works

What this page estimates

This Home Equity Investment Calculator is built to give a quick, browser-based estimate for home equity investment. HEI products give you cash today in exchange for a share of future appreciation. Compute total payback at exit and the effective annual cost — then compare to a HELOC or home equity loan. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.

Calculation approach

The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.

Example workflow

For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.

Practical checks

Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
Run a low, base, and high case when the inputs are estimates.
Check the related calculators below when the next decision depends on a different assumption.

How to interpret the home equity investment result

Best use

Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.

Cross-check

Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.

Watch for

Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.

This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.

Before relying on this home equity investment estimate

Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.

Confirm source numbers

Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.

Separate cash flow from total cost

A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.

Run conservative cases

Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.

Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions

How does an HEI differ from a HELOC?

HEIs charge no interest and require no monthly payments — you pay back the cash plus a share of appreciation at exit. HELOCs charge interest and require payments but the payback is fixed. HEIs are 'free' if the home doesn't appreciate but expensive if it does.

What's a typical investor share?

Often 1.5–4× the cash-as-percent-of-value ratio. Take 10% of value as cash → investor takes 15–40% of future appreciation. Specific terms vary by provider and underwriting.

When does an HEI cost more than a HELOC?

When appreciation is fast and term is long. A 6% HELOC vs an HEI: if your home appreciates 6%+/yr, the HEI costs more. If appreciation is 2%/yr, the HEI is much cheaper.

What if I want to pay off the HEI early?

Most HEIs allow early payoff but the appreciation share still applies based on appraised value at payoff. Read the contract carefully — minimum payoffs and appreciation floors can hurt early-payoff economics.
