Quick start
- Open the Home Equity Loan Calculator.
- Enter home value and current mortgage balance first. These two numbers set the equity picture.
- Use the first example, "$50k loan: $450,000 home, $260,000 mortgage, $50,000 loan", if you want to see a filled-out estimate before entering your own values.
- Calculate, read the formula line, then copy the result only after the amounts, percentages, time periods, or assumptions look right.
Best uses
Start here if one of these sounds like your job. The examples below show which inputs matter most.
- Estimate payment on a lump-sum home equity loan.
- Compare requested loan with available-equity estimate.
- Check combined loan-to-value after borrowing.
- See total interest over the fixed term.
What this calculator is for
The Home Equity Loan Calculator is for a lump-sum second loan. It shows the fixed payment, rough borrowing room, and combined loan-to-value after the new loan.
Good fit examples: Estimate payment on a lump-sum home equity loan. Compare requested loan with available-equity estimate.
What to enter
Finance estimates are sensitive to small input changes. Check whether a field expects a monthly amount, annual amount, dollar value, or percent before calculating.
- Enter home value and current mortgage balance first. These two numbers set the equity picture.
- Enter the desired loan amount, rate, term, and max combined loan-to-value percent.
- Use a realistic home value. If the home value is too high, the borrowing-room estimate will look safer than it is.
Example walkthrough
Try the calculator example: $50k loan: $450,000 home, $260,000 mortgage, $50,000 loan. The example result is Payment and CLTV.
- $450,000 home value, $260,000 mortgage balance, and an 85% max CLTV gives about $122,500 of estimated borrowing room.
- A $50,000 requested loan at 8.25% for 10 years estimates about $613 per month before lender fees and closing costs.
Formula and steps
In plain language: The calculator estimates available equity from home value, mortgage balance, and max combined LTV, then applies the fixed-payment loan formula to the requested loan amount. It does not pull an appraisal, choose a lender CLTV rule, include closing costs, or decide whether the loan is affordable.
If the estimate looks surprising, check the formula and inputs before using the answer in a budget, comparison, or planning note.
How to read the answer
Start with the headline result. Then read the supporting lines to see what made the number larger or smaller, such as rates, time periods, costs, taxes, fees, discounts, or contributions.
- Available equity at limit is the rough borrowing room under the CLTV cap you entered.
- Combined LTV shows the first mortgage plus the requested equity loan compared with home value.
- Monthly payment and total interest are for the new equity loan only, not the original mortgage.
Common mistakes to avoid
Most bad finance estimates come from mixing rates, terms, monthly amounts, and annual amounts. The other common mistake is using a planning estimate as if it were a final quote.
- Do not forget that the home is collateral. Missed payments can put the home at risk.
- Do not compare by payment alone when upfront fees, APR, closing costs, and rate type differ.
- Do not assume an estimated home value, online valuation, or CLTV cap means approval.
- Do not assume interest is tax deductible unless the loan use and IRS rules match.
What to try next

- Use Loan Calculator for a non-home-secured comparison.

FAQ in plain language
When should I use the Home Equity Loan Calculator?
Use it when you want to test the exact inputs on this page: Estimate payment on a lump-sum home equity loan. Compare requested loan with available-equity estimate. The result is a check against your assumptions, not proof that a lender, tax app, broker, platform, or provider will use the same number.
What do the main Home Equity Loan Calculator inputs mean?
Home value means your best current estimate of what the home could appraise or sell for, not the original purchase price. Current mortgage balance means what you still owe on loans already secured by the home. Desired equity loan means the new lump-sum amount you want to test as a fixed loan. Interest rate means the yearly rate for the new loan. Enter 8.25 for 8.25%, not 0.0825. Loan term means how many years the new home equity loan would be repaid over. Max combined LTV means the combined loan-to-value limit you want to test, such as 80 or 85.
Is this a home equity loan or a HELOC calculator?
This page is for a lump-sum home equity loan with a fixed payment. A HELOC is different because it is a line of credit that may let you draw money more than once and often has a variable rate.
What does combined loan-to-value mean?
Combined loan-to-value compares all home-secured debt with the home value. If you owe $260,000 on the first mortgage and test a $50,000 equity loan on a $450,000 home, the combined LTV is about 68.9%.
What is the Home Equity Loan Calculator doing with my numbers?
In plain language: The calculator estimates available equity from home value, mortgage balance, and max combined LTV, then applies the fixed-payment loan formula to the requested loan amount. It does not pull an appraisal, choose a lender CLTV rule, include closing costs, or decide whether the loan is affordable.
How should I read the Home Equity Loan Calculator answer?
Read available equity first, then combined LTV, then monthly payment. For the starter example, a $450,000 home with a $260,000 mortgage and an 85% CLTV cap leaves about $122,500 of borrowing room. A $50,000 loan at 8.25% for 10 years estimates about $613 per month before fees.
What does this estimate leave out?
This does not approve credit, protect against foreclosure risk, include lender fees, tax rules, property value changes, or underwriting limits. Home equity borrowing is secured by the home. If payments are missed, the home can be at risk. Tax treatment can also depend on how the money is used, so check IRS rules or a tax professional before assuming interest is deductible.
