Profit and Loss Calculator
Profit and loss the way school books do it: profit or loss and its percentage from CP and SP, the selling price from a profit or loss %, the cost price from SP, and discounts on the marked price.
About the Profit and Loss Calculator
Profit = SP − CP when you sell for more than you paid; loss = CP − SP when you sell for less. Profit and loss percentages are always worked out on the cost price, while a discount is worked out on the marked (list) price.
For a business's margin on the selling price, use the profit margin calculator instead.
The formula
Profit % = (SP − CP) ÷ CP × 100; SP = CP × (100 + P%) ÷ 100
- CP
- cost price
- SP
- selling price
- MP
- marked price; SP = MP − discount
Worked example
A cycle bought for ₹800 is sold for ₹920.
- Profit = 920 − 800 = 120
- Profit % = 120 ÷ 800 × 100 = 15%
Questions people ask
Why is profit % on CP and not SP?
By convention in school maths. A margin on the selling price is a different measure, used in business.
How do I find CP from SP and a loss?
CP = SP × 100 ÷ (100 − loss%). Choose 'Selling price and profit or loss %'.
