A Home Equity Line of Credit (HELOC) is a revolving credit line secured by your home's equity. It works like a credit card with your home as collateral. According to the CFPB, a HELOC allows you to borrow up to a set credit limit during the draw period and repay the balance over the repayment period.
A home equity line of credit calculator is an essential tool for homeowners looking to access their home's equity. Unlike traditional loans, a HELOC operates in two distinct phases that affect how you calculate HELOC payments and manage your monthly financial obligations.
When you use a home equity line of credit payment calculator, you'll notice calculations differ significantly between the draw period and repayment period. The draw period typically lasts 5-10 years, during which you can access funds and often make interest-only payments. The repayment period follows, typically lasting 10-20 years, where you must repay both principal and interest. Because most HELOCs carry variable interest rates, your payment can change when the rate adjusts, as explained in FTC consumer guidance on home equity lines of credit.
| HELOC Phase | Duration | Payment Type | Access to Funds | Payment Calculation |
|---|---|---|---|---|
| Draw Period | 5-20 years | Interest-only or Principal + Interest | Yes, up to credit limit | Balance × (Interest Rate ÷ 12) |
| Repayment Period | 10-30 years | Principal + Interest | No new borrowing | Standard amortization formula |
An interest only home equity line of credit calculator focuses on the draw period payments, which are typically the lowest monthly payments you'll face. To calculate HELOC payment interest only, multiply your outstanding balance by your monthly interest rate (annual rate divided by 12).
Monthly Interest-Only Payment = Outstanding Balance × (Annual Interest Rate ÷ 12)
Example: $50,000 balance × (6.5% ÷ 12) = $270.83 monthly payment
When using a home equity line of credit calculator monthly payment feature for the repayment period, the calculation becomes more complex. You'll need to calculate HELOC repayment using standard loan amortization formulas that include both principal and interest components.
The line of credit home equity calculator uses this formula for repayment period calculations:
M = P × [r(1+r)^n] / [(1+r)^n - 1]
Where:
M = Monthly payment
P = Principal balance
r = Monthly interest rate

| Scenario | HELOC Draw | Interest Rate | Draw Period Payment | Repayment Period Payment | Total Interest Cost |
|---|---|---|---|---|---|
| Interest-Only During Draw | $75,000 | 7.0% | $437.50 | $581.47 | $117,053.81 |
| Principal + Interest Throughout | $75,000 | 7.0% | $498.98 | $498.98 | $104,631.67 |
