HELOC Comparison Calculator

HELOC Calculator


  • Based on your inputs, the HELOC calculator will tell you how much you can borrow, how much your monthly payments will be, and how much tax savings you can expect to realize.

  • The HELOC calculator also generates monthly payments either for fully-amortized HELOC loans (i.e. payments include interest and principal) or loans requiring interest-only payments.

  • To determine tax benefits of a HELOC loan, you should know your marginal tax rate, which can be found here: 2006 Tax Table
