What we do
We translate every major home equity investment into one comparable number, the effective annual cost of the money, and we explain the product in plain English through our guide and HEI University. The calculator runs entirely in your browser, and it is free.
Who we are
HEI Calculator is built and maintained by a small, independent team.
Independence and disclosure
- We do not sell home equity investments and we are not a lender or broker.
- Rankings come only from the math applied to your inputs and each provider's published terms.
- If we ever have a paid relationship with a provider, we will disclose it on the pages where it applies.
How we verify provider terms
Every default term in the calculator follows the same rules:
- Provider first. We use each provider's own published materials, including its worked examples, before anything else.
- Reputable reviews second. Where a provider does not state a term on its own site, we use a recent, reputable review and label that term as coming from a third party.
- No guessing. If a provider does not publish a pricing term at all, we do not invent one. We mark that provider as needing your quote.
- Linked. Every term is listed with its source links on our provider terms & sources page.
Important: real offers are priced individually and vary by state, property, and underwriting. Our defaults show how each provider's published structure behaves; your written offer is what counts. You can enter its exact terms in the calculator's editor.
Editorial standards
- Education, not advice. We explain how products work and what they cost. We do not tell you which to choose.
- Plain English. If a term needs a definition, we define it.
- Balanced. We cover when an HEI makes sense and when it does not, including its risks.
