How this calculator works
Profit = Revenue - Cost.
Profit Margin = Profit / Revenue × 100.
Markup = Profit / Cost × 100.
Example
If an item sells for ₹1,000 and costs ₹700, profit is ₹300, margin is 30% and markup is about 42.86%.
Frequently asked questions
What is the difference between margin and markup?
Margin divides profit by revenue, while markup divides profit by cost.
Can profit margin be negative?
Yes. If cost is greater than revenue, profit and margin are negative.
Should I use gross cost or all business expenses?
Use the cost definition that matches the margin you want to measure, such as product cost for gross margin or broader costs for another profitability view.
