Frequently Asked Questions

How is profit percentage calculated?
Profit % = (SP − CP) ÷ CP × 100. If SP is ₹650 and CP is ₹500, profit % = 30%.
What is the difference between profit % and gross margin?
Profit % is calculated on cost price; gross margin is calculated on selling price. The same transaction gives a different number for each metric.
How do I find the selling price for a target profit %?
SP = CP × (1 + Target% ÷ 100). For 25% profit on a ₹800 item: SP = ₹800 × 1.25 = ₹1,000.
When does a loss occur?
A loss occurs when SP < CP. Loss % = (CP − SP) ÷ CP × 100.
Can I use this for GST-inclusive prices?
Yes — enter GST-inclusive prices to get overall P&L. For GST-exclusive analysis, remove GST from the prices first using the GST Calculator.
What gross margin is considered healthy for retail?
It varies by industry. Grocery retail: 20–30%. Apparel: 40–60%. Electronics: 10–20%. Software products often exceed 70% gross margin.
How do I find the selling price if I know my target profit %?
Use the Reverse Calculator above. Select "Find Selling Price", enter your cost and desired profit %, and the SP is calculated instantly. Formula: SP = CP × (1 + Profit% ÷ 100).
How much discount can I offer without making a loss?
The "Max discount before loss" row shows this. It equals the gross margin % — the maximum discount you can apply to the selling price before profit hits zero. Formula: Max discount = (SP − CP) ÷ SP × 100.
