HELOC math, in plain English

What is combined loan-to-value (CLTV)?

CLTV adds up every loan secured by your home, including your mortgage and the new HELOC, then divides the total by your home's value. Lenders use it to decide how much they will let you borrow. Many cap it at 80% to 85%, and a few go higher.

Why does my payment change after the draw period?

During the draw period most HELOCs only require interest on what you have borrowed. When repayment starts you pay back principal and interest, so the payment is usually higher. This calculator shows both.

Are HELOC rates fixed?

Most are variable and move with an index such as the prime rate, which is why we show a 2 point increase. Some lenders let you lock part of the balance at a fixed rate. Ask each lender.

How accurate is this?

It is an estimate. Lenders use their own home valuation, set their own limits, and may add fees or require more than the minimum payment. Your lender's quote is the number that counts.
