Margin Calculator Guide

Setting the right price for your product is the single most important decision for any business. Set it too high, and you lose customers. Set it too low, and you lose money.

Most business owners (and even MBA students) get confused between two very similar terms: Margin and Markup. Using the wrong one can lead to huge financial losses. This guide—and our calculator—is here to fix that.

1. The Battle: Margin vs Markup

They sound the same, they both deal with profit, but they are mathematically very different.

Markup

Markup is calculated on the Cost Price.


"I want to add 20% profit on top of my cost."

Gross Margin

Margin is calculated on the Selling Price.


"20% of my total sales revenue should be profit."

The Golden Rule:
Margin is ALWAYS lower than Markup.
If you want a 50% Margin, you need a 100% Markup!

2. The Gross Margin Formula

To find out how much of your revenue is actually yours to keep, use this formula:

Margin % = [ (Selling Price - Cost Price) / Selling Price ] × 100

Wait, what if you know the Cost (₹100) and want a 20% Margin? How do you find the Selling Price? The math gets tricky here:

Selling Price = Cost / ( 1 - (Margin % / 100) )

3. Real Life Example

Let's say you run a shoe shop.

  • You buy a pair of shoes for ₹1,000 (Cost).
  • You want to make a 20% Margin.

Wrong Way (Markup Mistake):
You add 20% of ₹1,000 = ₹200.
Selling Price = ₹1,200.
Actual Margin: (200 / 1200) = 16.6% (Oops! You missed your target).

Right Way (Using Formula):
Selling Price = 1000 / (1 - 0.20) = 1000 / 0.80
Selling Price = ₹1,250.
Check: Profit is ₹250. (250 / 1250) = 20%. Perfect!
