Illinois Home Equity Loan Calculator

By SoFi Editors | Updated December 11, 2025

For many homeowners, the equity built up in their property represents a significant financial asset. This value can be leveraged to secure financing for major expenses, such as home renovations, debt consolidation, or education costs. A home equity loan provides a powerful way to turn this equity into ready cash.

This guide will explain how a home equity loan works and demonstrate how you can use an Illinois home equity loan calculator to explore your potential borrowing capacity. Let’s get started.

  • Key Points
  • •   An online home equity loan calculator helps borrowers compare different loan scenarios and estimate payments.
  • •   A homeowner’s credit score and debt-to-income ratio are important factors for lenders when determining loan eligibility and terms.
  • •   A small difference in interest rates can lead to a large difference in the total cost of a loan.
  • •   Interest paid on a home equity loan may be tax-deductible.
  • •   Home equity loans typically have fixed interest rates, which ensures that monthly payments remain predictable.


Calculator Definitions

•   Home Value: This is the current estimated market value of your property — not the original price you paid but rather what it might sell for in today’s market.

•   Desired Loan Amount: This is the sum of money you wish to borrow. It should reflect the amount needed for your intended purpose, such as a renovation project or debt consolidation.

•   Current Mortgage Balance: Your balance is the total amount you still owe on your primary home loan plus the balance of any other existing loans that are secured by your home.

•   Home Equity Loan Repayment Term: The term is the length of time over which the loan will be repaid. Repayment terms for home equity loans range from five to 30 years.

•   Interest Rate: The interest rate is the cost of borrowing the money, which is multiplied by the loan balance. For most home equity loans, this rate is fixed for the life of the loan.

•   Maximum Loan Amount: This is the estimated highest amount a lender might be willing to offer you, based on your available equity.

•   Estimated Monthly Payment: You would pay this amount each month to repay the loan. The payment includes both the principal (the amount you borrowed) and the interest charges.

•   Available Equity Amount/Percentage: The home equity calculator will show you the cash value and the percentage of your home’s value that you own outright. Lenders typically want the homeowner to retain at least 15% of their equity as a protective cushion, so you won’t be able to borrow 100% of these numbers.

How to Use the Illinois Home Equity Loan Calculator

A home equity loan calculator is more than just a calculation tool; it’s a strategic resource that empowers you to model different financial scenarios. Follow these steps to use it properly:

Step 1: Enter Your Home Value

Input the current estimated market value of your home. This is the starting point for determining how much equity you have available.

Step 2: Input Your Desired Loan Amount

Enter the sum of cash you wish to borrow. This allows the calculator to determine if your requested amount is feasible based on your available equity.

Step 3: Enter Your Current Mortgage Balance

Input the remaining balance on your existing mortgage. If you have any other loans secured by your property, their balances should be included here as well.

Step 4: Select a Home Equity Loan Repayment Term

Select a loan term from the available options, which generally range from five to 30 years. Remember that longer terms result in lower monthly payments but lead to higher total interest costs over the life of the loan.

Step 5: Estimate Your Interest Rate 

Enter an estimated interest rate to see how it affects your monthly payment. Your actual offered rate will depend on several factors, including your credit history and debt-to-income ratio.

Step 6: Review Your Results

After you enter the required information, the home equity calculator will provide estimates for your monthly payment and the maximum potential loan amount.

What Is a Home Equity Loan?

Before you borrow against your home equity, it’s important to understand what a home equity loan is, exactly. At its core, a home equity loan is a second mortgage that allows you to borrow against the equity you have built in your property. The key characteristics define how it functions:

•  Lump-sum payout: The loan is disbursed as a single, upfront payment, making it ideal for large, one-time expenses with a known cost.

•  Fixed interest rate: It typically has a fixed interest rate, which  ensures that monthly payments are consistent, making budgeting easier.

•  Fixed repayment term: The loan is repaid over a period determined at its outset, usually between five and 30 years.

•  Secured by your home: These loans typically offer lower rates than unsecured personal loans or credit cards. But if you fail to make payments as agreed, you risk foreclosure.

Since 2020, the average amount of equity a homeowner has in Illinois has more than doubled. The average equity amount is now over $80,000. In fact, the state is one of the top five in equity growth from 2020 to 2025. Much of this growth is tied to increased home values. In the U.S. as a whole, about half of homeowners with a mortgage are considered “equity rich,” which means their mortgage balance is less than half of the home’s value. Take a look at how equity has risen in the U.S. as a whole in recent years.

How to Use the Home Equity Loan Calculator Data to Your Advantage

The output from a home equity loan calculator provides more than just numbers; it is a strategic planning resource. This data allows homeowners to assess affordability, compare different loan structures, and align their borrowing decisions with their financial goals.

By analyzing the Estimated Monthly Payment provided by the home equity loan payment calculator, you can determine how a new loan payment would fit into your existing budget. This is a critical step to prevent overextending yourself.

The Maximum Loan Amount gives you the lowdown on how to get equity out of your home and how much equity you might harness. This estimate will be useful if you are planning large-scale projects, such as a major renovation.

Finally, using the calculator to model different loan terms — for example, comparing a 10-year repayment term to 20-year one — illustrates the fundamental trade-off between lower monthly payments and higher total interest costs. Modeling different rates and terms in the calculator is an important step in your decisionmaking process.

Home Equity Loan Scenarios

Here are two scenarios that illustrate the practical applications of a home equity loan:

Scenario 1: Funding Home Renovations

Imagine a homeowner planning a complete kitchen remodel. They have obtained quotes and know the project will cost $40,000. A home equity loan is a good financing solution because it provides the full amount in a single lump sum, allowing them to pay the contractor and purchase materials without delay. The fixed monthly payments shown by the home equity loan payment calculator make it easy to budget for the repayment over a set term.

Scenario 2: Consolidating High-Interest Debt

Consider a homeowner with multiple high-interest debts, such as credit card balances and a personal loan, totaling $25,000. By taking out a home equity loan, they can pay off all these debts at once. This consolidates their multiple monthly payments into a single, predictable payment, often at a significantly lower interest rate, which can save them money and simplify their finances.

Tips on Home Equity Loans

Securing favorable terms on a home equity loan and using it wisely requires more than just having equity in your home. Take these smart steps as well:

•  Build a strong credit history. Lenders view a strong credit score as an indicator of financial responsibility. Lenders typically favor credit scores of at least 680 or higher for home equity loan applicants, with many preferring 700 or more.

•  Manage your debt-to-income ratio. Your debt-to-income (DTI) ratio, which is your total monthly debt payments divided by your gross monthly income, is a key metric for lenders. Lenders typically look for a DTI ratio below 50% for a home equity loan, and ideally below 36%. Reducing existing debts before applying for a home equity loan can lower your DTI and make you a more attractive borrower.

•  Understand the risks. Only borrow if you are confident in your ability to repay the loan. Missing payments could result in foreclosure.

•  Shop around. Interest rates, fees, and terms can vary significantly between lenders.Get offers from multiple financial institutions to compare your options.

•  Borrow only what you need. You might qualify for a large loan amount, and it can be tempting to borrow more than necessary. To avoid taking on extra debt, limit your loan to the amount required for your specific purpose.

Alternatives to Home Equity Loans

While a home equity loan is an attractive financial tool, it is not the only option available to homeowners who need access to funds. Although there aren’t different types of home equity loans, there are alternative ways to borrow based on home equity, as well as loans that don’t involve using your home as collateral.

Recommended: HELOC vs. Home Equity Loan

Home Equity Line of Credit (HELOC)

A HELOC is a revolving line of credit secured by your home. In practice, it’s much like a credit card. Borrowers can draw funds as needed up to a predetermined limit during a “draw period,” which typically lasts for several years. During this time, they need only pay interest on the borrowed amount (a HELOC interest-only calculator is useful).

After the draw comes the repayment phase, when borrowers pay both interest and principal. There’s a HELOC repayment calculator for that. Interest rates on HELOCs are usually variable so monthly payments aren’t entirely predictable. While a home equity loan typically allows borrowing up to 85% of your equity, a HELOC may allow up to 90%. HELOCs are ideal for times when you don’t entirely know how much you will need to borrow, or when a large project might require you to borrow in phases versus all at one time.

Home Improvement Loan

A home improvement loan is a type of unsecured personal loan specifically intended for renovation projects. Because it is unsecured, your home is not used as collateral, eliminating the risk of foreclosure. While funding can be faster, interest rates may be higher, and loan amounts are often smaller compared to a home equity loan.

Personal Line of Credit

Similar to a HELOC, a personal line of credit is a revolving line of credit. But this credit line is not secured by your home. Funds can be drawn as needed up to a set limit. Interest rates may be higher than those for a HELOC or home equity loan because there is no collateral for the credit line.

Cash-Out Refinance

A cash-out mortgage refinance replaces your existing primary mortgage with a new, larger one, and the difference is paid to you as a lump sum of cash. This option is often limited to borrowing up to 80% of your home equity. Unlike a home equity loan, which adds a second monthly payment, a cash-out refinance results in only one mortgage payment.

When you consider a cash-out refinance vs. a home equity line of credit or home equity loan, an important consideration will be current mortgage interest rates. If they are higher than the rate you have with your current home loan, a home equity loan or HELOC might be a better borrowing option.

The Takeaway

For Illinois homeowners, a home equity payment calculator is a useful tool when you want to estimate your borrowing capacity and understand what potential monthly payments might be. Doing research with the calculator can help you approach the lending process with a clearer understanding of what to expect. It is also important to compare offers from different lenders before committing to a specific loan — in the long run, doing so will be well worth a small investment of your time.

FAQ

How is a home equity loan different from a home equity line of credit (HELOC)?

A home equity loan provides a one-time lump sum of cash that is repaid with monthly payments at a fixed interest rate. In contrast, a HELOC is a revolving line of credit with a typically variable interest rate. You can borrow and repay funds as needed during a set draw period, usually 10 years. With a home equity loan, you begin making payments on the interest and principal at once. HELOCs typically allow you to pay only interest during the draw phase.

How much can I borrow with a home equity loan?

The amount you can borrow is based on your home’s value, existing mortgage balance, income, and credit. Lenders typically limit borrowing up to 85% of your equity.

Is the interest rate on a home equity loan fixed or variable?

Home equity loans almost always come with a fixed interest rate. This means the rate shown by the home equity payment calculator will not change over the life of the loan, resulting in predictable and consistent monthly payments. A home equity line of credit, on the other hand, typically has a variable rate.

Are there closing costs or fees with home equity loans?

Yes, home equity loans typically have closing costs, which often amount to 2% to 5% of the total loan amount. These costs can include fees for appraisal, title search, and loan origination. Some lenders may offer no-closing-cost options, which might come with a slightly higher interest rate.
