Profit vs profit margin
Many mix up the two, and that confusion leads to bad pricing decisions. The difference is simple: profit is an amount in pounds, and profit margin is a percentage that measures how much profit each pound of sales returns. Let's clarify with an example, the types of margin, and how Zemam computes them straight from your books.
Profit
An amount in pounds = revenue − cost. “How much did I make?”
Profit margin
A percentage = profit ÷ revenue × 100. “How much does each pound of sales return?”
A simple example
You sold an item for 100, its cost was 70 → profit = 30, and profit margin = 30 ÷ 100 = 30%.
Why is margin more telling than profit alone?
The profit number alone can deceive because it's driven by sales volume. Look at the difference:
| Shop A | Shop B | |
|---|---|---|
| Revenue | 1,000,000 | 200,000 |
| Cost | 980,000 | 160,000 |
| Profit | 20,000 | 40,000 |
| Margin | 2% | 20% |
Shop A sells 5× more, but earns less with only a 2% margin — any small problem tips it into a loss. Shop B is far more efficient at 20%. Profit alone would have deceived you.
Gross margin and net margin
Gross profit & margin
Gross profit = revenue − cost of goods sold (COGS). Gross margin = ÷ revenue. It measures the product's own profit — whether your pricing is right.
Net profit & margin
Net profit = revenue − all expenses (salaries, rent, …). Net margin = ÷ revenue. It measures the company's real profit after everything.
How Zemam calculates it
Zemam computes all of this straight from the general ledger — not an estimate. Gross profit = revenue − cost of sales (from the actual entries), and margin = profit ÷ revenue × 100. And it shows you: the gross-profit trend over time, gross margin per item category (so you know which category has a weak margin), and net profit from the income statement. Every figure traces back to real journal entries.
Frequently asked questions
Does a big profit number mean my business is healthy?
Not necessarily. Profit is an absolute number driven by sales volume, but margin tells the real story: a shop selling 1,000,000 at 20,000 profit (2% margin) is weaker than one selling 200,000 at 40,000 profit (20% margin) — even though its sales are higher. Margin measures the efficiency of every pound of sales.
What's the difference between gross margin and net margin?
Gross margin = (revenue − cost of goods sold) ÷ revenue — it measures the product's profit before operating expenses. Net margin = (revenue − all expenses) ÷ revenue — it measures the company's profit after salaries, rent, and everything. Gross tells you if your pricing is right; net tells you if the company is actually profitable.
Does Zemam calculate margin per product or category?
Yes. Zemam shows gross margin per item category (revenue, cost, profit, and margin %), the gross-profit trend over time, and net profit from the income statement — so you know which product or category actually earns and which has a weak margin.
What's the difference between margin and markup?
The two get mixed up. Margin = profit ÷ selling price. Markup = profit ÷ cost. An item costing 70 sold at 100: profit is 30 — margin is 30% (30÷100), but markup is 43% (30÷70). If you confuse them in pricing, you can think your margin is higher than it really is.
