Frequently Asked Questions
How is profit percentage calculated?
Profit ÷ cost price × 100. Buying at 400 and selling at 500 gives a profit of 100, which is a 25% profit on cost.
Why is the percentage based on cost rather than selling price?
Profit and loss percentages in commerce and school syllabuses are always relative to cost price. When you want the percentage of revenue instead, that is called margin — use the profit margin calculator.
What is the break-even price?
The selling price at which profit is exactly zero: cost price plus any extra costs. Selling below it loses money on every unit.
Should shipping count as a cost?
Yes, if you paid it. Any cost you cannot recover reduces your profit, so include shipping, payment processing fees and packaging in the extra costs field for a realistic answer.
