Built by a Mortgage Professional.
Made for Everyday Homeowners.
HELOCPaymentCalc.com exists for one reason: to give homeowners a clear, accurate picture of what a home equity line of credit actually costs — before they sign anything.
Why HELOCPaymentCalc.com Exists
Most HELOC calculators online show you one number: the draw payment. That’s the low, interest-only monthly payment that looks attractive on paper. What they don’t show you — or bury deep in fine print — is the repayment payment, the total interest over the life of the loan, and what happens when rates rise.
This site was built to fix that. Enter your numbers once and you get the full picture: draw payment, repayment payment, total interest cost, LTV check, rate stress scenarios, and a complete month-by-month amortization schedule. No email required. No ads in the way. No upsells.
An informed borrower makes better decisions. That’s the entire mission of this site.
How We Know What We Know
The content on HELOCPaymentCalc.com is grounded in real mortgage lending experience. Lucas Green spent over a decade working directly with homeowners on home equity products — reviewing loan files, explaining amortization schedules, and helping borrowers understand the true cost of borrowing against their home.
The HELOC calculator uses the same financial formulas that banks and mortgage servicers use internally — the standard interest-only formula during the draw period and the full amortization formula for the repayment period. These aren’t estimates. They’re the same calculations your lender runs.
All editorial content — rate guidance, LTV rules, state-specific information, and Q&A — is based on current lending standards and updated to reflect 2026 market conditions.
Our Commitment to Accuracy & Transparency
Every calculation uses standard financial math — the same formulas used by banks and mortgage servicers. No shortcuts, no approximations.
This site provides calculations and education — not personalized financial advice. We always recommend consulting a licensed mortgage professional before making borrowing decisions.
Nothing you enter into the calculator is stored, shared, or tracked. All calculations happen in your browser. Your financial information stays private.
This site has no lender partnerships, no affiliate commissions, and no sponsored content. Recommendations are based solely on what’s accurate — not what’s profitable.
How We Research and Write Content
- 1Primary sources first. Rate data comes from Federal Reserve releases, published prime rate benchmarks, and publicly available lender disclosures — not aggregator estimates.
- 2Real-world lending experience. Content is written by Lucas Green based on firsthand experience in mortgage origination and home equity lending, not compiled from secondary sources.
- 3Regular updates. Rate information, LTV guidelines, and state-specific rules are reviewed and updated to reflect current market and regulatory conditions.
- 4Clear limitations disclosed. Where individual circumstances affect outcomes — tax deductibility, lender-specific terms, credit score impact — we say so explicitly and recommend professional guidance.
If you spot an error in any calculation or content, or have a question about how the calculator works, reach out directly. Accuracy matters here — corrections are taken seriously and addressed promptly.
