Turnover vs Net Profit: Why Understanding Both Matters for Business Success

When reviewing your business’s performance, it’s essential to know the difference between turnover and net profit.
They are related, but they measure very different aspects of your financial health — and mixing them up could cost you.
This guide explains both clearly, with examples, a comparison table, and a free calculator to check your own figures.
Quick Definitions
Turnover:
Total income generated from sales, before deducting any expenses.
Net Profit:
The final amount left after all business expenses (COGS, salaries, rent, marketing, taxes, interest) are deducted from turnover.
Example: Turnover vs Net Profit
Imagine an online retailer:
- Turnover (Sales) = £500,000
- COGS (Stock and fulfilment costs) = £250,000
- Operating Expenses (wages, marketing, rent) = £180,000
- Taxes and Interest = £20,000
Calculations:
✅ Turnover = £500,000
✅ Net Profit = £50,000

Final Thoughts
Turnover is important because it shows how much business you’re generating.
But net profit is critical because it shows whether your business model is sustainable.
You can't spend turnover — you can only spend profit.
Understanding both — and improving both — leads to smarter decisions, better planning, and stronger business health.
