United States HELOC

Estimate the monthly payment on a home-equity line of credit in the United States.

About United States HELOC

HELOCs use a variable rate tied to the prime rate in the United States. In the draw period payments are often interest-only, then the balance amortizes in repayment. This shows both modes.

Formula

Payment

Interest-only: P × monthly rate; Amortized: standard PMT

  • Estimate — variable rates change with prime.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Are HELOC rates fixed?

How accurate is this estimate?
