Introduction

Home equity is the part of your home that you truly own. It is the difference between what your home is worth and what you still owe on your mortgage. This Home Equity Calculator helps you find out how much equity you have and how much you may be able to borrow against it.

Lenders look at a number called your combined loan-to-value ratio (CLTV) to decide if you qualify for a home equity loan or a HELOC. This tool calculates that ratio for you. It also shows your estimated interest rate, monthly payment, and total interest based on your credit score, loan term, and property type.

Enter your home value, mortgage balance, and the amount you want to borrow. The calculator will tell you if you are likely eligible, how much you could borrow, and what your payments might look like. If you do not qualify, it will show you clear steps to get there, such as how much mortgage to pay down first.

How to Use Our Home Equity Calculator

Enter details about your home, your loan needs, and your credit profile. The calculator will show how much equity you have, how much you can borrow, your estimated rate, and your monthly payment.

Estimated Home Value: Type in what your home is worth today. Use a recent appraisal or a best guess based on similar homes sold near you.

Current Mortgage Balance: Enter the amount you still owe on your primary mortgage. You can find this on your latest mortgage statement.

Additional Liens / Other HELOCs: If you have a second mortgage, an existing HELOC, or any other debt tied to your home, enter the total here. Leave it at $0 if you have none.

ZIP Code: Type in your 5-digit ZIP code. Rates and lender options can change based on where you live.

Property Occupancy Type: Pick how you use the property. Choose primary residence, vacation home, or investment property. This affects your estimated rate.

Loan Type: Choose between a home equity loan or a HELOC. A home equity loan gives you one lump sum at a fixed rate. A HELOC is a credit line you draw from as needed.

Requested Loan / Line Amount: Enter the amount of money you want to borrow. If this is more than you qualify for, the calculator will adjust it down for you.

Loan Term: Pick how many years you want to repay the loan. Shorter terms mean higher monthly payments but less interest paid overall.

Payment Type (HELOC only): This option appears when you select HELOC. Choose interest-only to pay just the interest each month, or full repayment to pay down the balance over time.

Maximum LTV Threshold: Pick a lender scenario of 80%, 85%, or 90%. This sets the maximum combined loan-to-value ratio allowed. Most lenders cap at 80%, but some go higher.

Credit Score Range: Select the range that matches your credit score. A higher score will give you a lower estimated rate.

What Is Home Equity?

Home equity is the part of your home that you truly own. It is the difference between what your home is worth and what you still owe on your mortgage. For example, if your home is worth $300,000 and you owe $200,000, your home equity is $100,000.

How Home Equity Borrowing Works

Lenders let you borrow against your home equity using a home equity loan or a home equity line of credit (HELOC). A home equity loan gives you a lump sum of money at a fixed interest rate. You pay it back in equal monthly payments over a set number of years. A HELOC works more like a credit card. You get a credit limit and can borrow what you need, when you need it, usually at a variable rate.

What Is Loan-to-Value (LTV)?

Loan-to-value, or LTV, is a ratio lenders use to measure risk. It compares how much you owe on your home to how much your home is worth. A lower LTV means you own more of your home, which makes lenders more willing to approve you. Most lenders want your combined LTV (CLTV), which includes your mortgage, any existing liens, and the new loan, to stay at or below 80%. Some lenders allow up to 85% or 90%, but the interest rate is usually higher. If your LTV is above 80% on your primary mortgage, you may also be paying private mortgage insurance.

What This Calculator Does

This home equity calculator estimates how much equity you have, how much you could borrow, and what your monthly payment might be. It factors in your home value, mortgage balance, credit score, loan type, and loan term to give you a clear picture. The results include your LTV, CLTV, estimated interest rate, and a full breakdown of costs across different repayment terms. All figures are estimates. Your actual rate, loan amount, and eligibility depend on the lender you choose.

Frequently asked questions

How is home equity calculated?

Home equity equals your home's current value minus what you owe on your mortgage. If your home is worth $400,000 and you owe $250,000, your equity is $150,000. Enter your home value and mortgage balance, and the calculator computes it instantly.

What is a good combined loan-to-value (CLTV) ratio?

A CLTV below 80% is considered good. Most lenders prefer this range because it means you still own at least 20% of your home after borrowing. Some lenders allow up to 85% or 90%, but you will likely pay a higher interest rate.

What is the difference between LTV and CLTV?

LTV looks at just your primary mortgage compared to your home's value. CLTV adds up all debts tied to your home (your mortgage, any existing liens, and the new loan you want), then compares that total to your home's value. Lenders use CLTV to decide if you can borrow more.

What is the difference between a home equity loan and a HELOC?

A home equity loan gives you one lump sum at a fixed rate with equal monthly payments. A HELOC is a revolving credit line, similar to a credit card, where you borrow what you need at a variable rate. Use the loan type toggle in this calculator to compare both options.

What does interest-only payment mean on a HELOC?

Interest-only means you pay just the interest each month during the draw period. Your balance does not go down. This gives you a lower monthly payment, but you still owe the full amount at the end. Switch to full repayment in the calculator to see how payments differ.

How does my credit score affect my home equity rate?

A higher credit score gets you a lower interest rate. For example, an excellent score (750+) might get a rate around 7.25%, while a poor score (below 650) could see rates above 10%. Use the credit score dropdown to see how your score changes the estimated rate and monthly payment.

How much home equity can I borrow?

The maximum depends on your home value, mortgage balance, additional liens, and the lender's LTV limit. The formula is: (Home Value × LTV Threshold) − Mortgage Balance − Other Liens. This calculator shows you the exact amount under the threshold you pick.

Why does property type change my estimated rate?

Lenders charge more for vacation homes and investment properties because they carry more risk. A second home adds about 0.50% to the rate, and an investment property adds about 1.00%. Primary residences get the lowest rates.

Do additional liens affect how much I can borrow?

Yes. Any existing second mortgage, HELOC, or other lien on your home is subtracted from your borrowing capacity. The calculator includes these debts when computing your CLTV and maximum borrowable amount. Enter all liens for an accurate result.

Can I use home equity for any purpose?

In most cases, yes. Common uses include home renovations, debt consolidation, education costs, and emergency expenses. However, using the funds for home improvements may offer tax benefits on the interest paid. Check with a tax advisor for your specific situation.

Why does my CLTV go above the threshold even though I picked a lower amount?

Your CLTV is based on the full requested amount you entered, not the adjusted eligible amount. If your request exceeds what the threshold allows, the gauge and CLTV reading will reflect that. The calculator will still cap the payment and borrowing results at your true maximum.

How often should I check my home equity?

Check it at least once a year or whenever your home value changes significantly. Rising home prices increase your equity. Paying down your mortgage also builds equity over time. Rerun this calculator whenever you get a new appraisal or see big changes in local home prices.
