Fact checked

A HELOC is a revolving line of credit that’s taken out against your home’s equity. Use our calculator for an idea of what to expect as far as eligibility and funding.

Key takeaways

  • Your estimated HELOC amount is based on your home’s value, what you owe and your lender’s maximum LTV. Most lenders allow you to borrow up to 80% of your home’s value minus your outstanding mortgage balance, though some go higher.
  • The calculator result is a starting point, not a guarantee. Your actual approved amount will depend on the lender’s full assessment of your creditworthiness — including your credit score, income and DTI ratio.
  • You’ll generally need a credit score of at least 650 to be approved for a HELOC, though a higher score will improve your chances and help you qualify for a better rate.

How to use the HELOC calculator

  1. Enter your home’s estimated value. If you need help estimating this number, try searching online real estate listing sites to see how much similar homes in your area are worth.
  2. Enter how much you still owe on your mortgage. You can find this number on recent mortgage statements, or by logging in to your online mortgage account.
  3. If needed, adjust the maximum loan-to-value ratio. Because most lenders allow you to borrow up to 80% of your home’s value, this number is set to 80% by default.
  4. Based on the information you’ve provided, the calculator will show an estimated line of credit amount.

What’s the caveat?

Your calculated result is a rule of thumb only. The exact amount you’re able to borrow depends on the lender’s assessment of your risk, including how much it’s willing to let you borrow against your home’s value and your overall creditworthiness. Most lenders look for a credit score of at least 650 for approval.

Overall costs depend on your interest rate during the draw period, how much you end up borrowing against your balance and other factors.
