Basic Profit and Loss Formulas
Profit Formula:
textCopyEditProfit = Selling Price (SP) – Cost Price (CP)
If you earn more from selling than you spent to acquire, that’s profit.
Loss Formula:
textCopyEditLoss = Cost Price (CP) – Selling Price (SP)
If you sell it for less than what you paid, you incur a loss.
Profit and Loss Percentage Formulas
Understanding percentages helps you compare gains or losses relative to your investment.
Profit Percentage:
textCopyEditProfit % = (Profit / Cost Price) × 100
Loss Percentage:
textCopyEditLoss % = (Loss / Cost Price) × 100
Profit and Loss Tricks You Must Know
These shortcuts will help you solve problems faster:
Reverse Selling Price Trick
If Profit % = 20%, then
textCopyEditSelling Price = (120 / 100) × Cost Price
If Loss % = 10%, then
textCopyEditSelling Price = (90 / 100) × Cost Price
Use these ratios for quick mental math.
Percentage Change Shortcut
To calculate percentage profit or loss directly:
textCopyEdit% Change = [(SP – CP) / CP] × 100
This trick is helpful when you need fast percentage results.
Double Transaction Trick
If a person sells two items at the same price—one at x% profit and the other at x% loss—then they incur a net loss, calculated by:
textCopyEditOverall Loss % = (x² / 100)%
Example: If one item is sold at 20% profit and another at 20% loss:
Overall Loss = (20 × 20) / 100 = 4%
Marked Price and Discount Trick
If a product has a marked price and discount is given:
textCopyEditSP = Marked Price × (1 – Discount%)
Then apply profit or loss formula on SP and CP.
