This is the only way to evaluate to insure you make a profit. We all work too hard to only earn wages and not profits. Many agents have bought themselves a job and never make a profit. Profits continue on, they are the extra you have after you pay your wages and all your bills. Profits, if invested, beget more profits, which create financial independence.
Wages merely cover the monthly bills.
Agents need to view the whole picture, the gross and the net. If you want the true reality after all the hype and fluff of sales volume, gross commission earned, and all the other ego stroking we do, look at line 31 on your federal tax return. That is reality. That is what you truly made for your labor last year. What you are taxed on, is what you made.
