## Questions and answers from the visible page

### What is profit margin?

Profit margin is gross profit divided by sales, expressed as a percentage. For example, sales of ₹1,000 and cost of ₹700 produce ₹300 profit and a 30% margin.

### What is the difference between margin and markup?

Margin divides profit by sales. Markup divides profit by cost. They describe the same profit amount from different starting points, so their percentages are not interchangeable.

### Is GST included in the profit calculation?

Enter sales and cost excluding GST. The calculator shows GST and the invoice total separately, helping registered businesses avoid treating collected GST as revenue.
