Practical business calculations for pricing, profit, margins and everyday commercial decisions.

How to use these calculators

Business calculations are most useful when the inputs match the way the business actually operates. Cost price, selling price, quantity, fees and overheads can all change the meaning of a profit figure. Use these calculators to make the arithmetic visible, then check the assumptions against real invoices, records or course examples before relying on the result.

Before you make the decision

Treat calculator results as a worked estimate rather than a substitute for accounting records or professional advice. For student exercises, follow the definitions used in your course; for real business decisions, include relevant taxes, fees and overheads that a simple calculation may not capture.
