Another reason you calculate profit ... profit allows you to understand the tradeoff between short-term profit and long-term profit.
You should calculate profit per new customer. Right? Right??
Say you acquire 10,000 new customers and you lost $24,000 doing so. Your profit per new customer is ($24,000) / 10,000 = ($2.40). You lost $2.40 to acquire each new customer.
Ok, now you probably calculate lifetime value (or some derivation of it) ... right? Right?? Let's assume you calculate LTV. You know that the customer delivers $11.88 profit in year one on the file.
You lost $2.40 acquiring the customer.
You generate $11.88 within just a year.
Yup, that's a good decision. You want to do MORE of this, don't you? You want to ask your CFO for more money, because the short-term loss is actually a long-term profit.
Then you execute your plan and sales increase by 10% ... all because of YOU ... because you calculated profit. Everybody in the company benefits, Management earns a healthy bonus, and it's all because of YOU.
Yes ... YOU!
Calculate this stuff, ok? It's like printing money as far as future career salary potential is concerned.
