Question

What are three diffferent methods to determine buying power?

Answer 1

Buying Power

The money an investor has available to buy securities. In a margin account, the buying power is the total cash held in the brokerage account plus maximum margin available.

Also referred to as "excess equity."

For example, if you have $1,000 cash in a margin account and the maximum margin rate is 50%, then your total buying power is $2,000. For a non-margin account, the buying power is equal to the amount of cash in the account.

Answer 2

One aspect is disposable income.
