How the home equity line of credit calculator works
It multiplies your home’s value by the lender’s maximum combined loan-to-value to find the most total debt allowed, then subtracts your existing mortgage. What remains is the home equity line you may be able to borrow.
Worked example: with home value of $450,000, mortgage balance of $250,000 and max combined loan-to-value of 85.00%, the home equity line of credit (heloc) calculator shows available credit line of $132,500.

Questions about the home equity line of credit calculator
How much can I borrow with a HELOC?
Lenders cap your mortgage plus HELOC at a combined loan-to-value, often 80–90% of the home’s value. The difference between that cap and your mortgage is your available line.
What is combined loan-to-value?
Your total home-secured debt (mortgage plus HELOC) divided by the home’s value. Lenders set a maximum to keep an equity cushion against price drops.
Do I have to borrow the full line?
No — a HELOC is revolving credit. You draw only what you need and pay interest only on the amount you actually borrow.
