What is a home equity loan calculator?

A home equity loan calculator tells you how much you can borrow against your home and what it would cost to repay it. Home equity is the portion of your home you own — the current market value minus the outstanding mortgage balance. As you pay down the mortgage or as your home appreciates, your equity grows. This free calculator takes four inputs: home value, mortgage balance, annual rate and term, then returns your available equity, loan-to-value ratio and the monthly payment. It also shows your loan-to-value ratio before you apply.

The monthly payment uses the standard amortizing formula, spreading principal and interest evenly across the term. The display uses $ for the example, but the estimate is currency-agnostic and runs entirely in your browser. Note that lenders often limit borrowing to around 80% of a home's value, so you may not be able to access all of your equity.

How to use

Enter the current market value of your home.
Enter the outstanding balance on your mortgage.
Set the annual interest rate and the repayment term in years.
Click Calculate equity to see available equity and the monthly payment.

How home equity is calculated

Available equity = Home value − Mortgage balance
Monthly payment  = P × (r/12) ÷ [1 − (1 + r/12)^(−n)]

Loan-to-value ratio is the balance divided by the home value. The payment formula then spreads the loan amount P over n months at an annual rate r, including both principal and interest.

Example

With the defaults — a $400,000 home, $250,000 mortgage balance, 6% rate and a 15-year term — click Calculate equity. Your available equity is $150,000, your loan-to-value ratio is 62.50%, and the monthly payment is $1,265.79. Over the term you will pay about $77,841 in interest. Since lenders often cap borrowing near 80% of the home value, you may only be able to access part of your equity.

Who is the home equity loan calculator for?

Your home equity is the slice of your home you actually own — the market value minus what you still owe. This calculator is built for anyone weighing a lump-sum loan against that equity.

Students and young adults: a home equity loan calculator for students is mainly a learning tool here — it demos how value, balance and rate drive equity so you can plan a first property purchase with eyes open.
Couples: map how much equity a growing property backs and how a fixed monthly payment fits a two-income budget before committing to a renovation or consolidation loan.
Salaried professionals: compare a home equity loan against a HELOC or refinance and size a payment that stays comfortable inside a monthly salary.
Retirees: tap the equity built up over a lifetime of mortgage payments to fund a large expense, choosing a rate and term that keep the payment within a fixed retirement income.

Home equity loan table (6% rate, 15-year term)

This table shows available equity and the fixed monthly payment on a $400,000 home at a 6% annual rate over 15 years. How to calculate a home equity loan: subtract the mortgage balance from the home value for the equity, then amortize that amount over the term. The payment uses the equity as the loan principal, and note that lenders often cap borrowing near 80% of the home's value — so your accessible equity may be less.

Available equity = Home value − Mortgage balance. LTV = Balance ÷ Home value. Monthly payment = P × (r/12) ÷ (1 − (1 + r/12)^(−n)). A good home equity loan has a competitive rate and a payment that never strains your cash flow.

Mortgage balance ($)	Available equity ($)	LTV ratio	Monthly payment ($)	Total interest ($)
200,000	200,000	50.00%	1,687.71	103,788.46
250,000	150,000	62.50%	1,265.79	77,841.34
300,000	100,000	75.00%	843.86	51,894.23
320,000	80,000	80.00%	675.09	41,515.38

Common use cases

Fund a renovation: borrow against your equity to pay for home improvements.
Consolidate debt: use a home equity loan to pay off higher-interest balances.
Cover a big expense: finance education, medical costs or other large purchases.
Check your options: compare a home equity loan against a HELOC or refinance.

Pro tips

Lenders cap at ~80% LTV: your maximum combined loan-to-value usually limits how much equity you can borrow.
Compare a HELOC: a home equity loan is fixed and lump-sum, while a HELOC is a variable-rate line of credit.
Watch the payment: a longer term lowers the monthly payment but increases the total interest paid.
Consider fees and taxes: closing costs and the tax treatment of the interest can change the real cost.

FAQ

What is home equity?

Home equity is the portion of your home you own outright, equal to the current market value minus the outstanding mortgage balance.

What is a home equity loan?

A home equity loan lets you borrow a lump sum against your available equity at a fixed interest rate, repaid over a set term.

How do I calculate the monthly payment?

Use the amortization formula: Payment = P × (r/12) ÷ (1 − (1 + r/12)^(−n)), where P is the loan, r the annual rate and n the number of monthly payments.

What is loan-to-value (LTV) ratio?

LTV is the mortgage balance divided by the home value, expressed as a percentage. It is a key measure of how much of the home is still financed.
