Profit

Profit is what is left after every expense has taken its share. It is the only number that tells you whether the business is actually a business. And it comes in three flavors, each of which tells a different story.

Three different numbers. Three different questions.

"Are you profitable?" is one of the most-asked questions in business. It is also one of the most useless, because the answer depends entirely on which profit you mean. There are three of them, sitting at three different levels of the income statement, and they tell three completely different stories about a business.

A founder who says her business is profitable might mean any of the three. The investor sitting across from her cares which one.

Profit, in the simplest definition, is what is left after expenses are subtracted from revenue. It is the reason businesses exist. Revenue without profit is just activity. Profit is what the activity produces — the actual return for everyone who has put money, time, or risk into the business.

The three flavors map directly onto the expense categories we just covered. Each one strips a layer of expense away from revenue and shows what is left.

Gross profit is revenue minus the cost of goods sold. It is the money left over after paying for the direct production of whatever you sold. If a coffee shop does $100,000 in sales and spends $30,000 on beans, milk, cups, and barista labor, its gross profit is $70,000. Expressed as a percentage of revenue, that is a 70% gross margin. Gross profit answers the question: does the basic act of selling this product make money? If the gross margin is negative or near zero, no amount of cost-cutting elsewhere will save the business. The unit economics do not work.

Operating profit, sometimes called earnings before interest and taxes (EBIT), is gross profit minus operating expenses. It takes the gross profit and subtracts the rent, the salaries of non-production staff, the marketing budget, the software subscriptions, the insurance — everything it costs to run the business beyond producing what gets sold. If the coffee shop's $70,000 gross profit had $50,000 of operating expenses against it, the operating profit is $20,000. Operating profit answers the question: does the business as a whole make money from its operations? This is the cleanest measure of whether the company can sustain itself.

Net profit, sometimes called net income or the "bottom line," is operating profit minus interest, taxes, and any other expenses below the operating line. It is the money that actually belongs to the owners after every other party has been paid. If the coffee shop's $20,000 operating profit pays $4,000 in loan interest and $5,000 in taxes, the net profit is $11,000. That is the real bottom line. That is what is left for the owner. Net profit answers the question: after every claim against the business has been satisfied, what remains?

All three numbers matter. A business with strong gross margins and weak operating margins has a fundamentally good product but is being eaten alive by overhead — fix the overhead and the business becomes excellent. A business with weak gross margins and strong operating margins has the opposite problem: cost discipline is good, but the underlying economics of selling the product are bad, and no amount of operational excellence will rescue them. A business with strong operating profit but weak net profit is being suffocated by interest payments or taxes — there are real opportunities to restructure debt or change tax strategy. The three margins, read together, point to where the business actually needs work.

One more critical distinction. Profit is not cash. A business can be profitable on paper and still go broke. The reason is that profit is calculated using accrual accounting — revenue is recorded when an invoice is sent, expenses are recorded when they are incurred, regardless of when money actually moves. A consulting firm can record $200,000 of profit for the quarter while having $0 in the bank because clients have not paid their invoices yet. (See Cash Flow vs Profit for the longer version of this story. It is the difference that quietly kills the most profitable-looking businesses.)

"Are you profitable?" should always be answered with a question: which one do you mean? The three answers are different, and the difference is the entire story.
