Understanding business
Every business decision ultimately comes down to numbers — costs, prices, margins, conversion rates and cash flow. Knowing these figures precisely helps you price products profitably, control expenses, pay your team correctly and invest your marketing budget where it earns the best return. Quick calculations also make it easier to explain decisions to partners, investors or your accountant.
Common mistakes to avoid
- Mixing units (e.g. months vs years, cm vs m)
- Using an outdated rate or price
- Rounding intermediate values too early
- Forgetting fees, taxes or extra costs

Tips for the best results
- Use actual numbers from your books or ad dashboards instead of estimates where possible.
