Profit & loss calculator FAQs

What is the formula for profit percentage?

Profit% = (Profit ÷ Cost Price) × 100. The calculator uses this formula and displays the percentage as part of the result.

Can I enter zero or negative values?

Cost and selling prices must be non-negative. If your cost price is zero, the calculator treats the trade as break-even for percentage purposes.
