HELOC Calculator

How to Use the HELOC Calculator

This free HELOC calculator helps you determine how much equity you can access in your home and what your monthly payments will be. Enter your home value, current mortgage balance, the percentage your lender allows as a credit limit (typically 80%), the HELOC interest rate, the amount you plan to draw, and the repayment period. The calculator instantly shows your available equity, monthly payment (principal plus interest), interest-only payment, and total interest cost.

A HELOC is one of the most flexible ways to tap into your home equity. Unlike a traditional home equity loan, a HELOC works like a credit card secured by your property. During the draw period, you can borrow and repay as needed, paying interest only on the amount you use. Understanding the costs before you borrow is essential for making a sound financial decision.

Understanding HELOC Payments

Most HELOCs have two phases. During the draw period, typically 5 to 10 years, you can borrow money and usually make interest-only payments. During the repayment period, typically 10 to 20 years, you repay both principal and interest. This calculator shows both the interest-only payment and the fully amortized payment so you can plan for both phases.

HELOC vs. Home Equity Loan

A home equity loan gives you a lump sum with a fixed rate, while a HELOC provides revolving credit with a variable rate. Choose a HELOC if you need flexible access to funds over time, such as for ongoing home renovations. Choose a home equity loan if you need a specific amount upfront and prefer the predictability of fixed payments.

Tips for Using a HELOC Wisely

Borrow only what you need and can afford to repay. Keep in mind that HELOC rates are typically variable, meaning your payments could increase if interest rates rise. Use HELOC funds for value-adding purposes like home improvements rather than consumable expenses. Maintain an emergency fund separate from your HELOC, and never treat your home equity as an ATM for discretionary spending.

Frequently Asked Questions

What is a HELOC and how does it work?

A Home Equity Line of Credit (HELOC) is a revolving credit line secured by your home equity. Unlike a home equity loan that gives you a lump sum, a HELOC lets you borrow as needed up to your credit limit during a draw period (typically 5-10 years), then repay during a repayment period (10-20 years).

How much equity can I borrow with a HELOC?

Most lenders allow you to borrow up to 80-85% of your home value minus your outstanding mortgage balance. For example, if your home is worth $400,000 and you owe $250,000, with an 80% limit you could access up to $70,000.

Are HELOC interest payments tax deductible?

HELOC interest may be tax deductible if the funds are used to buy, build, or substantially improve your home. Interest on HELOC funds used for other purposes is generally not deductible under current tax law.

What happens if my home value decreases?

If your home value drops, your lender may reduce your credit limit, freeze your line of credit, or require early repayment. This is why it is important not to borrow the maximum available.

What is the difference between a HELOC and a home equity loan?

A HELOC is a revolving line of credit with variable rates where you borrow as needed. A home equity loan provides a fixed lump sum with a fixed interest rate and predictable monthly payments.
