The heloc interest formula

FinanceLearn states the heloc interest formula as:

Im=B×r12I_m = \dfrac{B \times r}{12}

BB is the drawn balance. rr is the annual rate as a decimal. ImI_m is the interest-only monthly charge.

The working tool is the HELOC calculator. The explainer is how a HELOC works. The one-sentence term is HELOC.

How to apply it

Read the symbols, then run the how to calculate it walk on the calculator. Match the convention first. Two people can write the same words and mean a monthly rate or an annual rate.
