A home equity line of credit (HELOC) lets you borrow against your home's equity, but you cannot borrow against all of it. Lenders have limits on how much equity you can access, based on your home's value, your mortgage balance and your financial picture. Understanding how much equity you need for a HELOC helps you set realistic expectations before you apply.
The short answer: HELOC eligibility depends on your home's value, your outstanding mortgage balance, your combined loan-to-value ratio, your credit and your income. Lenders typically require you to keep a cushion of equity in the home. See our guide on how a HELOC works for the full picture.
What is home equity?
Home equity is the difference between your home's current value and what you owe on your mortgages. As you pay down your loan and as your home's value rises, your equity grows.
For example, if your home is worth $350,000 and you owe $200,000 on your mortgage, your equity is $150,000.
Combined loan-to-value ratio (CLTV)
Lenders use a combined loan-to-value ratio (CLTV) to decide how much you can borrow. CLTV compares your total mortgage debt (first mortgage plus any second mortgage or HELOC) to your home's value.
The basic idea:
CLTV = (total mortgage debt ÷ home value) × 100
For example, if your home is worth $350,000 and you owe $200,000, your current LTV is about 57 percent. If a lender allows a maximum CLTV of 80 percent, you could borrow up to 80 percent of $350,000 ($280,000) total, minus your $200,000 balance — leaving up to $80,000 in HELOC availability (before other requirements).
These numbers are for illustration only and do not represent a guarantee or an offer.
Outstanding mortgage balances
Your current mortgage balance reduces the equity you can access. The more you owe, the less room you have for a HELOC. Paying down your mortgage over time increases your available equity.
Lender requirements
Each lender sets its own HELOC requirements, which can include:
- A maximum CLTV (often 80 to 85 percent, but it varies)
- A minimum credit score
- A maximum debt-to-income ratio
- Stable, documented income
- A satisfactory appraisal
- Reserves or cash on hand
Because requirements vary, ask your lender for the specific limits that apply to your situation.
Credit and income
Your credit and income matter as much as your equity. A stronger credit profile and stable income can improve your options, while a higher debt-to-income ratio can limit how much you can borrow — even with plenty of equity.

Available credit limits
Even if you qualify, your HELOC limit may be lower than the maximum you could borrow. Lenders may set a lower limit based on your credit, income or their own risk guidelines. You only pay interest on what you draw, not on the full limit.
How to estimate your HELOC eligibility
- Estimate your home's current value (an appraisal will confirm it).
- Add up what you owe on your mortgage(s).
- Calculate your current LTV and your potential CLTV.
- Ask your lender for the maximum CLTV it allows.
- Subtract your current balance from the maximum allowed debt to estimate available equity.
- Remember that credit, income and DTI also affect your final limit.
How to build more equity
If you do not have enough equity yet, you can build more by:
- Paying down your mortgage balance
- Making home improvements that add value
- Waiting for your home's value to rise
- Avoiding new debt against the home
Frequently asked questions
How much equity do I need for a HELOC? It depends on the lender's maximum CLTV, your credit and your income. Lenders typically require you to keep a cushion of equity in the home.
What is CLTV? Combined loan-to-value ratio. It compares your total mortgage debt (first mortgage plus any HELOC) to your home's value.
Can I borrow all of my equity? Usually no. Lenders require you to keep a cushion of equity, so your HELOC limit is less than your total equity.
Does my credit affect my HELOC limit? Yes. Your credit, income and debt-to-income ratio all affect how much you can borrow, not just your equity.
