What is this?
A Home Equity Line of Credit (HELOC) Calculator is a financial tool that helps estimate interest payments, repayment amounts, and total borrowing costs for a home equity line of credit. It calculates how much interest accrues during the draw period and how much you will pay during the repayment period based on the credit line, interest rate, fees, and loan terms.
How to Use the Home Equity Line of Credit (HELOC) Calculator
A Home Equity Line of Credit (HELOC) Calculator helps homeowners estimate
interest payments, repayment amounts, and the total borrowing cost when
using a line of credit secured by their home equity.
A HELOC typically includes two phases: the draw period and the repayment
period. During the draw period, borrowers can withdraw funds and usually
pay interest only. During the repayment period, both principal and interest
are repaid. The calculator estimates these payments and provides a detailed
schedule to help borrowers understand their financial commitment.
1. Enter the Credit Line Amount
Input the total credit line you expect to borrow using your home's equity.
This represents the maximum amount available through the HELOC.
2. Enter the Interest Rate
Provide the annual interest rate offered by your lender. The calculator
uses this rate to estimate interest payments during both the draw and
repayment periods.
3. Specify the Draw Period
Enter the number of years in the draw period. During this phase, you can
borrow funds and usually make interest-only payments on the outstanding
balance.
4. Enter the Repayment Period
Specify the repayment period when both principal and interest must be
paid until the loan balance is fully repaid.
5. Include Fees and Closing Costs
If applicable, include closing costs and annual fees. The calculator will
factor these expenses into the total cost of the credit line.
6. Click Calculate
Submit the form to generate estimated payments, total interest costs,
and both monthly and annual amortization schedules.
Key Formulas Used in the Calculator
Interest Payment During Draw Period
During the draw period, borrowers typically make interest-only payments. The interest payment is calculated using the outstanding balance and the monthly interest rate.
Monthly Repayment Formula
This standard amortization formula calculates the fixed monthly payment during the repayment period. P is the loan balance, r is the monthly interest rate, and n is the total number of payments.
Monthly Interest Rate
The annual interest rate is divided by 12 to determine the monthly interest rate used in HELOC payment calculations.
