What HELOC Calculator - Home Equity Line of Credit Calculator does
A HELOC Calculator determines monthly payments across both phases of a Home Equity Line of Credit: the draw period, where borrowers can access funds and typically make interest-only payments, and the repayment period, where principal and interest are due. Users input loan amount, interest rate, and term lengths to receive side-by-side estimates for interest-only and full amortization payments, clarifying the long-term cost difference between the two approaches. The site’s version distinguishes itself by explicitly mapping HELOC mechanics to real-world borrowing limits. It explains the 85% combined loan-to-value cap, walks through a concrete example ($400,000 home with $240,000 first mortgage yielding a $100,000 accessible HELOC), and pairs the calculator with a strategy-and-risks section. This educational framing—linking input numbers to lending rules and strategic warnings—is more detailed than typical bare-budget calculators.

HELOC Calculator - Home Equity Line of Credit Calculator FAQ
- What is the typical draw period length for a HELOC?
- The draw period is typically 10 years, during which borrowers can withdraw funds and usually make interest-only payments before the repayment phase begins.
- How is the maximum HELOC amount determined?
- Lenders generally allow HELOCs up to 85% combined loan-to-value ratio, meaning the first mortgage plus the HELOC cannot exceed 85% of the home's appraised value.
- What is the difference between interest-only and full payments in a HELOC?
- During the draw period, borrowers often make interest-only payments; after the draw ends, the repayment period requires full principal plus interest payments, significantly increasing the monthly obligation.
- Can this calculator show how much I might qualify for?
- Yes, by entering your home value and current mortgage balance, the tool calculates your accessible HELOC amount based on the 85% CLTV limit.
