Common questions

What is the difference between margin and markup?

Margin is profit divided by selling price. Markup is profit divided by cost. Cost ₹80, price ₹100: margin 20%, markup 25%.

How do I find the selling price for a target margin?

Divide cost by (1 − margin/100). Cost ₹80 for a 20% margin → ₹80 ÷ 0.8 = ₹100.

Should I calculate margin before or after GST?

Use prices without GST. GST you collect is paid to the government, so it is not your profit.
