Create a free accountMarkup vs. margin
Markup is the percentage added on top of cost to reach a selling price. Margin is the percentage of the selling price itself that represents profit. The two produce different prices for the same percentage — this calculator computes whichever one you choose, never both at once.
GST-exclusive vs. GST-inclusive
GST-exclusive adds GST on top of your calculated price. GST-inclusive treats your calculated price as the final, customer-facing price and works out the pre-tax price and profit from it — useful when you price by a fixed, round customer-facing number.
How profit is calculated
Profit is always your pre-tax selling price minus your cost — GST collected on a sale is money you pass on to the government, never your profit, regardless of whether you price GST-exclusive or GST-inclusive.
Important notes
This calculator covers the current GST 2.0 slabs (0%, 3%, 5%, 18%, 40%, effective 22 September 2025 under CBIC Notification No. 9/2025-Central Tax (Rate)) and simple cost/margin/markup pricing. It does not account for input tax credit, composition scheme, or other business-specific tax positions. This tool is provided for pricing convenience only — for tax filing or compliance decisions, consult a qualified tax professional.
Frequently asked questions
What is the difference between markup and margin?
Markup is the percentage you add on top of your cost to set a selling price (e.g. 20% markup on a ₹1,000 cost gives a ₹1,200 price). Margin is the percentage of the selling price that is profit (a 20% margin on the same ₹1,000 cost gives a ₹1,250 price) — they use different formulas and are not interchangeable.
How do I calculate selling price from cost and margin?
Selling Price = Cost ÷ (1 − Margin% ÷ 100). For example, a ₹1,000 cost at a 20% margin gives a selling price of ₹1,250.
How is GST calculated on selling price?
In GST-exclusive mode, GST is added on top of your calculated price: GST Amount = Price × GST% ÷ 100, and Final Price = Price + GST Amount. For example, a ₹1,000 price at 18% GST adds ₹180 GST for a ₹1,180 final price.
What is GST-inclusive pricing?
GST-inclusive pricing means the price your customer sees already includes GST — common for MRP-style or retail pricing. This calculator treats your calculated price as that final, GST-inclusive price and works backward to show the pre-tax price and your real profit.
What is GST-exclusive pricing?
GST-exclusive pricing means GST is added on top of your calculated price to arrive at what the customer actually pays.
How do I calculate the GST portion of an inclusive price?
Back-solve the pre-tax price first: Base Price = Final Price ÷ (1 + GST% ÷ 100). The GST amount is then Final Price − Base Price.
