How the Profit Margin Calculator works

The calculator uses simple math to produce accurate results:

Subtract cost price from effective selling price to get profit per unit.
If discount is applied it reduces selling price before tax.
If tax is applied it is added to the discounted selling price.
Profit percentage is (profit ÷ cost price) × 100.
Totals are profit, selling price and cost price multiplied by quantity.

Using this sequence ensures the Profit Margin Calculator reflects real-world pricing where discounts come before taxes.

Examples (quick scenarios)

Example 1 – Single unit profit
Cost Price: ₹200. Selling Price: ₹300. No discount, no tax.
Profit = ₹100. Profit Percentage = (100 ÷ 200) × 100 = 50%.
Our Profit Margin Calculator will show per-unit profit ₹100 and 50.00%.

Example 2 – Discount and tax applied, quantity 5
Cost Price: ₹100. Selling Price: ₹150. Discount 10% then Tax 5%. Quantity 5.
Selling after discount = 150 × 0.9 = ₹135. After tax = 135 × 1.05 = ₹141.75.
Per unit profit = 141.75 − 100 = ₹41.75. Total profit = ₹208.75.
The Profit Margin Calculator returns these numbers instantly.
