Home Equity Loan Calculator

Your home equity — the difference between what your home is worth and what you still owe on it — can be borrowed against, but lenders won’t let you tap all of it. This calculator finds how much equity is actually available to borrow given a typical lender loan-to-value limit, then calculates the monthly payment if that full available amount were borrowed as a fixed-rate loan.

How the Home Equity Loan Calculator Works

Enter your home’s current value, how much you still owe on your primary mortgage, the maximum loan-to-value ratio your lender allows, an interest rate, and a loan term, and the calculator first finds your available equity — your home’s value multiplied by the maximum LTV, minus what you already owe — then calculates the fixed monthly payment on that full available amount using a standard amortizing loan formula.

An Important Simplification: This Calculator Models a Full Lump-Sum Draw

This is genuinely important to understand before relying on this calculator’s payment figure, because it applies to a “home equity loan” (a one-time lump sum with a fixed payment schedule from day one) far more accurately than it applies to a HELOC (home equity line of credit), even though both share this same calculation internally. A real HELOC typically works quite differently in practice: it’s a revolving credit line you draw from as needed, often starting with a “draw period” of several years where you’re only required to pay interest on whatever balance you’ve actually drawn, followed by a separate repayment period where the outstanding balance converts to a fixed amortization schedule. This calculator instead assumes the entire available amount is borrowed immediately and repaid on a fixed schedule from the very first payment — a reasonable and accurate model for a traditional home equity loan, but a meaningful simplification if you’re actually evaluating a HELOC’s real-world interest-only draw period followed by a later repayment phase.

Loan-to-Value: The Number That Actually Limits What You Can Borrow

Lenders typically cap home equity borrowing at a combined loan-to-value ratio — commonly around 80-85% of the home’s value across both your primary mortgage and the new home equity borrowing combined — rather than letting you borrow against 100% of your equity. This exists to maintain a cushion of equity as protection against home value fluctuations; if home values dropped and a homeowner had borrowed against every available dollar of equity, even a modest decline could leave them owing more than the home is worth. This calculator’s LTV field lets you model your specific lender’s stated maximum directly, since that figure varies somewhat between lenders and loan programs.

Why This Isn’t the Same as a Cash-Out Refinance

A home equity loan or HELOC adds a second loan on top of your existing mortgage, leaving your original mortgage’s rate and terms completely untouched. A cash-out refinance instead replaces your entire existing mortgage with a new, larger one, extracting equity as part of that replacement rather than adding a separate loan alongside it. Which approach makes more financial sense depends heavily on how your existing mortgage’s rate compares to current rates — refinancing an existing low-rate mortgage into a new, higher-rate loan just to access equity can cost more overall than keeping the original mortgage in place and adding a separate home equity loan instead. If you’re specifically weighing a cash-out refinance rather than a second loan, the Refinance Calculator handles that comparison directly, including the break-even analysis for replacing your current mortgage entirely.

Common Uses for Home Equity Borrowing

Home equity loans and HELOCs are commonly used for home renovations (where the borrowed amount arguably increases the home’s value, partially offsetting the debt), debt consolidation at a potentially lower rate than credit cards, or major expenses like education costs — though borrowing against home equity for anything puts the home itself at risk as collateral if payments aren’t kept up, a genuinely different risk profile than unsecured debt.

Comparing Against a Personal Loan Instead

Home equity borrowing typically offers lower interest rates than unsecured debt precisely because the home serves as collateral, but that collateral requirement is exactly the trade-off worth weighing against alternatives. If you’re considering an unsecured personal loan instead — accepting a likely higher rate in exchange for not putting your home at risk — the Personal Loan Calculator covers that comparison directly, including a discussion of origination fees that home equity products sometimes handle differently.

Consolidating Existing Debt with Home Equity

If the specific goal is using home equity to pay off higher-interest debt — credit cards or other unsecured loans — rather than funding a new expense, the Debt Consolidation Calculator compares your existing debts’ combined cost directly against a proposed new loan’s terms, which is a useful side-by-side comparison before committing to using home equity specifically for that consolidation purpose.

Understanding Your Current Mortgage Balance and Equity Position

This calculator requires your current mortgage balance as a direct input, which assumes you already know that figure precisely. If you need to check your current remaining balance based on your original loan terms and how long you’ve been paying, the Mortgage Calculator and Amortization Calculator can help reconstruct that figure from your original loan details and payment history.

Frequently Asked Questions

Does this calculator work the same for a home equity loan and a HELOC?

It applies the same calculation to both, modeling a full immediate draw repaid on a fixed schedule — which accurately reflects how a traditional home equity loan works, but simplifies a real HELOC’s typical structure of an interest-only draw period followed by a separate repayment phase.

Why can’t I borrow against 100% of my home equity?

Lenders cap combined loan-to-value ratio, typically around 80-85%, to maintain an equity cushion protecting against home value fluctuations. Borrowing against every available dollar of equity would leave a homeowner more exposed to owing more than the home is worth if values declined even modestly.

What is the difference between a home equity loan and a cash-out refinance?

A home equity loan adds a separate second loan on top of your existing mortgage, leaving the original mortgage untouched. A cash-out refinance replaces your entire existing mortgage with a new, larger one. Which is more cost-effective depends heavily on how your existing mortgage’s rate compares to current market rates.

Is home equity borrowing riskier than a personal loan?

In a specific sense, yes — your home serves as collateral for a home equity loan or HELOC, meaning it’s at risk if payments aren’t kept up, unlike most personal loans, which are unsecured. This risk is generally offset by a lower interest rate compared to unsecured borrowing.

What does LTV mean in this calculator?

Loan-to-value ratio — the maximum combined percentage of your home’s value that a lender will allow across both your existing mortgage and any new home equity borrowing together. This figure varies by lender and loan program, so entering your specific lender’s stated maximum gives the most accurate available equity figure.
