Setting profitable retail and wholesale prices requires balancing cost price, target profit margins, and mandatory Goods and Services Tax (GST) compliance. The Finzorio GST Profit Calculator calculates your net profit, cost markup percentage, net selling price, CGST/SGST/IGST tax splits, and the final customer invoice price in one instant view.

The Difference Between Markup on Cost and Profit Margin

One of the most frequent accounting mistakes in small businesses is confusing Markup with Profit Margin:

  • Markup (% on Cost): The percentage added to the Cost Price to arrive at the Net Selling Price. (e.g., Buying for ₹100 and adding 25% markup gives a selling price of ₹125).
  • Profit Margin (% on Selling Price): The percentage of the Net Selling Price that represents profit. (e.g., Selling for ₹125 with ₹25 profit gives a 20% profit margin: 25 / 125 × 100).

GST is always applied on the Net Selling Price (Cost + Profit), never on cost alone.

GST & Commercial Profit Pricing Formulas

Markup Method: Net Selling Price = Cost Price × (1 + Markup% / 100)
Margin Method: Net Selling Price = Cost Price / (1 - Margin% / 100)
Net Profit = Net Selling Price - Cost Price
Total GST Amount = Net Selling Price × (GST Rate% / 100)
Final Invoice Price = Net Selling Price + Total GST Amount
  • Cost Price (CP) = Total procurement, manufacturing, or landing cost per unit
  • Intra-State Sale = Split equally between CGST (Central GST) and SGST (State GST)
  • Inter-State Sale = Levied entirely as IGST (Integrated GST)
  • Final Invoice Price = The gross MRP amount collected from the end customer

Worked Example: Pricing a Product with 20% Profit Margin & 18% GST

Scenario: A retail distributor buys an electronic appliance for ₹10,000 Cost Price and wants a clean 20% Profit Margin on selling price with 18% GST (Intra-state).

Inputs

  • Cost Price: ₹10,000
  • Profit Target: 20% Margin on Selling Price
  • GST Rate: 18% (Intra-State: 9% CGST + 9% SGST)

Calculation

  • Net Selling Price = ₹10,000 / (1 - 0.20) = ₹12,500 (ex-GST)
  • Net Profit Earned = ₹12,500 - ₹10,000 = ₹2,500 (20% of ₹12,500)
  • CGST (9%) = ₹12,500 × 0.09 = ₹1,125
  • SGST (9%) = ₹12,500 × 0.09 = ₹1,125
  • Total GST Collected = ₹2,250
  • Final Customer Invoice Price (MRP) = ₹12,500 + ₹2,250 = ₹14,750

Result: The distributor invoices the customer at ₹14,750. They pocket ₹2,500 net profit and remit ₹2,250 GST to the government.

3 Crucial Tax Tips for GST Registered Businesses

  • 1. Claim Input Tax Credit (ITC): Ensure all vendor purchase bills contain your correct 15-digit GSTIN to offset input GST against final invoice tax.
  • 2. Display GST Breakdown on Invoices: B2B invoices must clearly show taxable value, CGST, SGST/IGST, and HSN/SAC codes per GST compliance.
  • 3. Match Cash Flow for 20th of the Month: Monthly GST returns (GSTR-3B) and tax liability must be remitted by the 20th of every month to avoid 18% p.a. interest penalties.

Frequently Asked Questions

Profit margin is ALWAYS calculated on the pre-tax Net Selling Price (ex-GST). GST is a pass-through indirect tax collected from the customer and remitted to the government, so it does not count as revenue or profit for the business.

For sales within the same state (Intra-State), GST is split equally between CGST (Central Government) and SGST (State Government). For sales across state boundaries (Inter-State), the full rate is charged as IGST.

ITC allows businesses to deduct the GST they already paid on raw materials/purchases from the GST they collect on sales, ensuring tax is paid only on the newly added profit/value.
