Business calculators

The pricing sums that come up at the counter or while building a price list — margin, markup, and what a discount actually does to the number a customer pays.

Questions

What's the difference between margin and markup?

Margin is profit as a share of the selling price; markup is profit as a share of the cost price. The same rupee amount gives two different percentages depending on which one you're asked for — the profit margin calculator shows both from one input.

Is this useful for GST-registered pricing?

It handles the margin and discount arithmetic; it does not add or remove GST. Run your GST-inclusive or exclusive price through first, then use these on the base price.
