The buying power identity

FinanceLearn states the buying power formula as:

CC is cash and mm is the initial margin percentage written as a decimal. Borrowed amount is buying power minus cash.

The working tool is the buying power calculator. The explainer is buying power. The one-sentence term is buying power.

How to apply it

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