Five financial numbers every business team needs to understand

Executive overview

Most employees see revenue as what the company "makes" — it isn't. Net profit is what the business makes after all costs are paid.

The fix is financial literacy built around five numbers: revenue, direct variable cost, gross profit, operating expense (op-ex), and net profit. The game is simple: grow gross profit faster than op-ex.

The goal is not fluency — it is conversational fluency, enough to make better daily decisions.

The five numbers

1. Revenue — dollars generated from selling products or services
2. Directly variable cost — what it costs to produce each dollar of revenue
3. Gross profit — revenue minus direct cost
4. Op-ex — fixed infrastructure spend needed to deliver gross profit
5. Net profit — what remains after all expenses, direct and fixed

The game: gross profit vs. op-ex

• The metric that matters: gross profit ÷ op-ex = organisational productivity
• Op-ex can step up in increments, as long as gross profit grows faster
• Sales teams must care whether a sale is profitable, not just whether it was made
• More net profit creates resources to hire, invest, and serve customers better — the virtuous circle

Spreading financial literacy

• Everyone needs to know how the business makes money (its core revenue model)
• Everyone needs to know where they personally have the most impact — revenue side or cost side
• Goal is conversational, not expert-level; the finance leader owns the full income statement
• Freedom follows understanding: people who grasp the game can make autonomous, aligned decisions daily
