AI explanation
Formula
Loss = Cost price − Selling price; Loss % = Loss / Cost price × 100Worked example
Sold for ₹800, cost ₹1,000
| Field | Value |
|---|---|
| Cost price | 1000 |
| Selling price | 800 |
| Loss | -200 |
| Loss percentage | -20 |
Assumptions
- Loss percentage is calculated on cost price. This calculator shows the raw Selling price − Cost price amount, so a positive result here means the sale actually made a profit (see the Profit Calculator).
Frequently asked questions
How do I calculate loss percentage?
Subtract the selling price from the cost price to get the loss amount, then divide the loss by the cost price and multiply by 100 to get the loss percentage.
Why is the result shown as a negative number?
This calculator reports Selling price − Cost price directly, so a loss shows as a negative value and a profit would show as positive. A negative result here confirms a loss occurred.
Is loss percentage always calculated on cost price?
Yes, by convention loss (and profit) percentage is calculated as a share of the original cost price, not the reduced selling price.
