Home Equity Loan Calculator
Estimate payments and borrowing costs for a home equity loan.
Understanding Home Equity Loan Calculator
A home equity loan allows a homeowner to borrow money using the equity in a property as collateral. Home equity is generally the difference between the current value of the home and the outstanding balance of mortgages or other debt secured by the property. A home equity loan typically provides a specific amount that is repaid through scheduled payments over a defined period. Many home equity loans use fixed interest rates, although available terms and pricing vary by lender. The amount a homeowner may be able to borrow depends on factors such as property value, existing mortgage debt, lender loan-to-value requirements, credit history, income, debt obligations, and other underwriting criteria. Borrowing against home equity increases the total debt secured by the property and can increase the financial risk associated with the home. The Home Equity Loan Calculator estimates the current equity in the property, the proposed loan payment, combined loan-to-value ratio, total interest, and other basic borrowing measures using the information entered by the user. The results are mathematical estimates and do not determine eligibility or the actual amount a lender may approve.
The calculator first estimates current home equity by subtracting the existing mortgage balance from the home's value. It then calculates the payment for the proposed home equity loan using the loan amount, interest rate, and repayment term. The calculator also combines the existing mortgage balance with the new home equity loan to estimate the resulting combined loan-to-value ratio. This helps show how the new borrowing would change the amount of debt secured by the property relative to its estimated value.
Making the inputs meaningful
For Home Equity Loan Calculator, the most useful starting point is to enter values that match the situation you are actually comparing. In this version of the calculator, the main inputs include Home Value ($), Current Mortgage Balance ($), Home Equity Loan Amount ($), Interest Rate (%). Keeping those values consistent—especially the rate, amount, term, or frequency where applicable—makes the result easier to compare across different scenarios.
What this calculation can and cannot tell you
Treat the displayed figure as a calculation based on your assumptions rather than a promise about what will happen. Small changes in a rate, contribution, payment, term, or starting amount can materially change a financial result. If you are comparing options, change one important assumption at a time so you can see which input is driving the difference.

How the Home Equity Loan Calculator Works
The calculator first estimates current home equity by subtracting the existing mortgage balance from the home's value. It then calculates the payment for the proposed home equity loan using the loan amount, interest rate, and repayment term. The calculator also combines the existing mortgage balance with the new home equity loan to estimate the resulting combined loan-to-value ratio. This helps show how the new borrowing would change the amount of debt secured by the property relative to its estimated value.
Example
Home Value: $350,000
Current Mortgage Balance: $200,000
Home Equity Loan: $50,000
Interest Rate: 7%
Loan Term: 15 years
What This Home Equity Loan Calculator Calculates
The calculator estimates current home equity, the proposed home equity loan payment, annual principal and interest payments, total principal and interest, total interest, current loan-to-value ratio, combined loan-to- value ratio, and estimated equity remaining after the new loan. These measurements provide different perspectives on the proposed borrowing. Home equity shows the estimated value remaining after the existing mortgage, while the combined loan-to-value ratio shows the relationship between total secured debt and the property's estimated value.
Home Equity Formula
Home equity is estimated by subtracting the current mortgage balance from the home's current value.
Home Equity = Home Value − Current Mortgage Balance
For example, if a property is worth $350,000 and the outstanding mortgage balance is $200,000, the estimated home equity is $150,000.
Understanding Home Value
Home value represents the estimated current market value of the property. This value is important because lenders generally consider the property's value when determining how much additional debt may be secured against it. The value entered into this calculator is an assumption provided by the user. Actual property values may be determined through an appraisal, valuation model, market analysis, or another method used by a lender. Changes in property value can significantly affect estimated equity and loan-to-value ratios.
Understanding the Current Mortgage Balance
The current mortgage balance represents the amount still owed on the existing mortgage. It should reflect the outstanding principal balance rather than the original amount borrowed. A lower mortgage balance generally means more home equity when the property's value remains unchanged. Conversely, a higher mortgage balance reduces the equity available in the property.
Home Equity Loan Amount
The Home Equity Loan Amount represents the additional amount the homeowner intends to borrow. This is separate from the existing mortgage balance. The calculator does not determine the maximum loan amount a lender will approve. Actual borrowing limits can depend on lender-specific maximum loan-to-value requirements, credit qualifications, income, debt levels, property type, appraisal results, and other conditions.
Loan-to-Value Ratio
Loan-to-value ratio, commonly called LTV, compares the outstanding mortgage balance with the property's value.
Current LTV = Current Mortgage Balance ÷ Home Value × 100
A $200,000 mortgage balance on a $350,000 property produces a current LTV of approximately 57.14%.
Combined Loan-to-Value Ratio
When a homeowner takes a home equity loan, the existing mortgage and the new loan both represent debt secured by the property. The combined loan-to-value ratio considers both balances.
Combined LTV = (Current Mortgage Balance + Home Equity Loan) ÷ Home Value × 100
For example, a $200,000 existing mortgage combined with a $50,000 home equity loan produces total secured debt of $250,000. On a $350,000 home, the estimated combined LTV is approximately 71.43%.
Estimated Equity After the New Loan
The calculator estimates the equity remaining after the proposed home equity loan by subtracting the combined mortgage and home equity loan balances from the property's entered value.
Estimated Equity After New Loan = Home Value − Current Mortgage Balance − Home Equity Loan
This figure assumes the property value remains equal to the value entered into the calculator and does not account for future appreciation, depreciation, transaction costs, or changes in either loan balance.
Monthly Home Equity Loan Payment
The monthly payment is calculated using the proposed home equity loan amount, annual interest rate, and repayment term. The calculator assumes a fixed interest rate and equal monthly principal and interest payments.
Monthly Payment = P × r × (1 + r)n ÷ ((1 + r)n − 1)
In this formula, P represents the loan amount, r represents the monthly interest rate, and n represents the total number of monthly payments. When the interest rate is zero, the loan amount is divided equally across the number of payments.
Total Interest
Total interest estimates the interest paid over the full repayment period if the loan remains outstanding for the entire selected term and the interest rate remains unchanged.
Total Interest = Total Principal and Interest Payments − Loan Amount
This calculation does not include lender fees, closing costs, appraisal charges, taxes, or other transaction expenses.
Home Equity Loans and Existing Mortgages
A home equity loan is generally an additional loan secured by the same property as the existing mortgage. The homeowner therefore has more than one debt obligation associated with the property. The existing mortgage does not disappear when a home equity loan is obtained. The homeowner remains responsible for the original mortgage payment as well as the new home equity loan payment.
Home Equity Loan vs. Mortgage Refinance
A home equity loan generally provides additional borrowing while leaving the existing first mortgage in place. A refinance, by contrast, replaces an existing mortgage with a new mortgage. These structures can produce different interest rates, payment amounts, closing costs, repayment periods, and financial outcomes. This calculator focuses specifically on the additional home equity loan rather than replacing the existing mortgage.
Effect of a Larger Home Equity Loan
Increasing the home equity loan amount generally increases the monthly payment and total interest when the interest rate and term remain unchanged. It also increases the combined loan-to-value ratio and reduces the estimated equity remaining in the property.
Effect of a Higher Interest Rate
A higher interest rate generally increases both the monthly payment and total interest for the same loan amount and repayment period. Because home equity loans can involve substantial balances and multi-year repayment periods, even relatively small changes in the interest rate can materially affect the total borrowing cost.
Effect of a Longer Loan Term
A longer repayment term generally reduces the required monthly payment by spreading the loan across more payments. However, keeping the loan outstanding for a longer period can substantially increase the total interest paid. A shorter term generally produces higher monthly payments but can reduce total interest when the interest rate and loan amount remain unchanged.
Property Value and Home Equity
Home equity can change even when the mortgage balance does not change. Increasing property values generally increase equity, while declining property values can reduce equity. Because property values fluctuate, the amount of equity shown by this calculator should be considered an estimate based on the value entered by the user.
Risks of Borrowing Against Home Equity
A home equity loan is secured by the property. Borrowing against home equity therefore increases the debt attached to the home and creates an additional payment obligation. If the borrower cannot make required payments, the consequences can be serious because the property serves as collateral for the secured debt. Borrowers should consider their income, existing obligations, interest rate, loan term, and ability to maintain payments before taking additional debt against a property.
Closing Costs and Loan Fees
A home equity loan may involve costs such as appraisal fees, lender fees, title services, recording charges, origination fees, or other transaction expenses. These costs are not included in the calculator's payment or total interest calculations. If applicable, they should be considered separately when evaluating the overall cost of borrowing.
Home Equity Loan Example
Suppose a homeowner has a property valued at $350,000 and an existing mortgage balance of $200,000. The estimated home equity is therefore $150,000. If the homeowner takes a $50,000 home equity loan, total secured debt becomes $250,000. The combined loan-to-value ratio is approximately 71.43%. With a 7% fixed interest rate and a 15-year repayment period, the calculator estimates the monthly principal and interest payment for the new $50,000 loan and calculates the projected total interest over the selected term.
Understanding the Results
Home Value represents the estimated value of the property. Current Mortgage Balance represents the outstanding balance of the existing mortgage. Home Equity represents the estimated difference between these two amounts. Home Equity Loan Amount represents the additional borrowing entered by the user. Monthly Payment represents the estimated principal and interest payment for that new loan. Current LTV measures the existing mortgage relative to the property value. Combined LTV measures the existing mortgage plus the new home equity loan relative to the property value. Total Interest represents the estimated interest paid on the new home equity loan over the selected term.
Frequently Asked Questions
What is a home equity loan?
A home equity loan is a loan secured by the equity in a property. It provides a specific amount that is generally repaid through scheduled payments over a defined period.
How is home equity calculated?
Home Equity = Home Value − Current Mortgage Balance.
Does home equity equal the amount I can borrow?
No. Estimated home equity does not automatically equal the amount a lender will allow a homeowner to borrow. Lenders may apply maximum loan-to-value limits and other qualification requirements.
Does this calculator determine the maximum home equity loan?
No. It calculates the loan payment and related measures for the loan amount entered by the user. It does not determine lender-specific borrowing limits.
What is combined LTV?
Combined loan-to-value compares the existing mortgage plus the proposed home equity loan with the property's value.
Does a home equity loan replace my mortgage?
No. A home equity loan generally adds another loan secured by the property while the existing mortgage remains in place.
Does this calculator include my existing mortgage payment?
No. The monthly payment shown is for the new home equity loan only. The existing mortgage payment remains a separate obligation.
Does this calculator include property taxes?
No. Property taxes are not included in the calculated home equity loan payment.
Does this calculator include homeowners insurance?
No. Homeowners insurance is not included in the calculated payment.
Can I use a home equity loan for any purpose?
The permitted use of loan proceeds depends on the lender, loan agreement, applicable requirements, and the borrower's circumstances. This calculator does not evaluate how the borrowed funds are used.
Does a higher loan amount increase total interest?
Generally, yes. When the interest rate and term remain unchanged, a larger loan amount produces higher interest costs.
Does a longer term lower the monthly payment?
Generally, yes. However, a longer term can increase the total interest paid over the life of the loan.
Can property value affect my home equity?
Yes. Changes in property value can increase or decrease estimated home equity and can also affect loan-to-value ratios.
Does this calculator include closing costs?
No. Closing costs, lender fees, appraisal fees, and other transaction expenses are not independently calculated.
Is a home equity loan the same as a HELOC?
No. A home equity loan generally provides a specific lump-sum amount, while a home equity line of credit, or HELOC, typically provides a revolving credit line with different borrowing and repayment features.
Limitations of the Home Equity Loan Calculator
This calculator provides a simplified mathematical estimate based on the home value, existing mortgage balance, proposed home equity loan amount, interest rate, and repayment term entered by the user. It assumes a fixed-rate amortizing home equity loan with equal monthly principal and interest payments. It does not determine the maximum amount a lender may approve and does not evaluate credit history, income, debt obligations, property condition, appraisal results, or lender-specific underwriting requirements. The calculator also does not independently calculate property taxes, homeowners insurance, closing costs, lender fees, appraisal fees, prepayment penalties, or other transaction expenses. Home values and mortgage balances can change over time, which can affect actual equity and loan-to-value ratios. Actual loan terms, rates, fees, borrowing limits, and approval decisions depend on the lender and the specific transaction. The results are therefore estimates intended for comparing borrowing scenarios and understanding basic home equity loan mathematics. They should not be interpreted as a loan offer, approval, or guarantee of actual financing terms.
