If you own a home and its value has grown over time, you may be able to borrow against that increase — commonly known as your "equity." The calculator below lets you enter a few basic details to get a quick estimate of how much you might be able to borrow and roughly what your monthly payment could look like.
Keep in mind that this is only an estimation tool. Actual loan approval, interest rates, and eligibility depend on your lender's specific terms, your credit profile, income, and the true market value of your property. If you'd like to see the full picture of your primary home loan first, you can also compare it with a standard US Mortgage Calculator.
What Is a Home Equity Loan?
Home equity is the difference between your home's current market value and the remaining balance on your mortgage. For example, if your home is worth $400,000 and you still owe $200,000 on your mortgage, your equity is roughly $200,000. Most lenders will only let you borrow against a portion of that equity — typically up to an 80% Loan-to-Value (LTV) ratio — to keep their risk in check.
How to Use the Calculator
- Estimated Home Value: Enter your home's current approximate market value.
- Current Mortgage Balance: Enter how much you still owe on your existing home loan.
- Interest Rate: Enter the rate you expect to be offered, as a percentage.
- Loan Term: Choose how many years you'd like to repay the loan over (10, 15, or 20 years).
Click "Estimate Loan" and you'll see two figures: your estimated maximum borrowing capacity, and the approximate monthly installment based on the term you selected. If you're also repaying your original home loan, you can check your monthly EMI separately to get your complete monthly outflow.
What Determines Your Home Equity Loan Amount
- Current Market Value of the Property: A higher value generally means more potential equity.
- Outstanding Mortgage Balance: The less you owe, the more usable equity you have.
- Lender's LTV Policy: Most lenders cap LTV around 80%, though some allow slightly less or more.
- Credit Score and Income: These affect both your interest rate and your chances of approval.
- Loan Term Chosen: A longer term usually lowers your monthly payment but increases total interest paid over time.
If your existing mortgage balance is limiting how much equity you can access, it may help to read about how a second mortgage works before deciding on the right option for you.
Benefits and Risks of a Home Equity Loan
Home equity loans often come with lower interest rates than personal loans or credit cards, since they're secured against your property. They're commonly used for home renovations, education expenses, medical costs, or consolidating higher-interest debt. If you're deciding between a fixed and adjustable rate, it's worth understanding how an ARM mortgage could affect your rate over time.
That said, because the loan is secured by your home, falling behind on payments can put your property at risk. Before taking out a loan, carefully review your repayment capacity, and consider speaking with a licensed financial advisor if you're unsure.
Frequently Asked Questions (FAQs)
1. How much can I borrow with a home equity loan?
Your potential loan amount depends on your home’s value, existing secured debt and the lender’s maximum combined loan-to-value (CLTV) ratio. If your mortgage is your only home-secured debt, use this estimate:
Estimated additional borrowing = Home value × Maximum CLTV − Outstanding mortgage balance.
For example, a $500,000 home with a $300,000 mortgage and an 80% CLTV limit gives an estimated borrowing capacity of $100,000 before fees. Other liens and lender requirements can reduce that amount.
2. What is the monthly payment on a $50,000 home equity loan?
A $50,000 home equity loan at a fixed 8% annual interest rate over 10 years would have an estimated principal-and-interest payment of $606.64 per month, assuming 120 equal monthly payments. This is an illustrative calculation, not a current rate offer, and excludes fees, property taxes and insurance.
Your payment changes with the loan amount, interest rate and term. Use a home equity loan payment calculator to compare scenarios before choosing a repayment period.
3. Does this home equity loan calculator show the exact amount I will qualify for?
No. This home equity loan calculator provides an estimate from your inputs, not a preapproval or lending decision. Your lender must verify your income, credit history, existing debts and the property’s value. The approved amount also depends on the lender’s underwriting rules and borrowing limits. A calculator result does not reserve an interest rate or guarantee funding.
4. Do all lenders use an 80% loan-to-value limit for home equity loans?
No. An 80% limit is a planning assumption, not a universal lending rule. Limits vary by lender, loan product, property and borrower. For a second loan, the relevant measure is usually combined loan-to-value (CLTV): total home-secured debt, including the proposed loan, divided by the home’s value. Confirm your lender’s actual limit and how it counts existing home equity loans and HELOCs.
5. How do closing costs affect a home equity loan?
Home equity loan closing costs increase the cost of borrowing. Fees deducted from the loan proceeds reduce the cash you receive; fees paid upfront require extra cash at closing. If your lender allows fees to be added to the loan balance, you may also pay interest on them.
Compare the interest rate, annual percentage rate (APR), total closing costs and net proceeds. For a closed-end home equity loan, APR reflects interest and certain loan fees, so it may exceed the stated interest rate.
6. What is the difference between a home equity loan and a HELOC?
A home equity loan generally provides a lump sum with a fixed interest rate and scheduled monthly repayments. A home equity line of credit (HELOC) lets you borrow as needed up to an approved limit during a draw period, and its rate is usually variable. HELOC payments can change as the balance, rate or repayment phase changes. Both use your home as collateral, so missed repayments can put your home at risk.
7. Is a home equity loan the same as a home equity investment (HEI)?
No. A traditional home equity loan is repaid through monthly installments, usually at a fixed interest rate. A home equity investment (HEI), also called a home equity contract, typically provides cash without monthly loan payments but requires a later lump-sum settlement linked to your home’s value and the contract terms. Fees and the final settlement can be substantial. A standard home equity loan calculator does not model an HEI’s settlement formula.
