PTR CALCULATOR (PHARMA & FMCG)
Accurately calculate Price to Retailer and net profit margins excluding GST
- Enter MRP: Input the Maximum Retail Price printed on the product packaging.
- Select GST: Choose the applicable GST slab for the product (e.g., 12% for most medicines).
- Set Margin: Enter the retailer trade margin (standard is 20% in Indian pharma).
- The tool will automatically reverse-calculate the tax to give you the exact B2B billing price.
Why Exclude Tax?
In B2B distribution, trade margins are legally calculated on the Base Price (excluding GST), not the final MRP.
- Base MRP:
MRP ÷ [1 + (GST% ÷ 100)] - PTR (Excl. Tax):
Base MRP × [1 - (Margin% ÷ 100)] - Final Invoice PTR:
PTR (Excl. Tax) + GST Amount

What is a PTR Calculator?
In the Indian wholesale, pharmaceutical, and FMCG (Fast-Moving Consumer Goods) distribution network, PTR stands for Price To Retailer. It is the exact invoice price at which a distributor or stockist bills a retail shop owner for a product.
Calculating this price manually is notoriously frustrating because retail margins are legally required to be calculated on the base price of the product excluding GST, rather than being a simple discount off the Maximum Retail Price (MRP). Our PTR Calculator automates this complex reverse-tax calculation instantly.
How to Calculate PTR from MRP (The Formula)
Many new pharmacy owners and retailers make a critical accounting mistake: they simply subtract 20% from the MRP. This results in inaccurate GST filing. To find the true Price to Retailer, you must follow a three-step mathematical process:
Let’s assume a medicine strip has an MRP of ₹150, a 12% GST slab, and a standard 20% Retailer Margin.
Step 1: Reverse-Calculate the Base MRP (Remove GST)
Base MRP = MRP ÷ (1 + (GST / 100))Base MRP = 150 ÷ 1.12 = ₹133.93Step 2: Apply the Retailer Margin
The retailer earns 20% on the Base MRP, so the distributor bills them at 80% of the Base MRP.
PTR (Excluding Tax) = 133.93 × 0.80 = ₹107.14Step 3: Add GST Back to Generate Final Invoice Price
GST Amount = 107.14 × 0.12 = ₹12.86Final PTR (Including Tax) = 107.14 + 12.86 = ₹120.00In this scenario, the retailer buys the product for ₹120.00, sells it for ₹150.00, and makes a net profit of ₹26.79 (the remaining ₹3.21 is collected as output GST).
Standard Trade Margins in India
While FMCG products (like soaps, shampoos, and snacks) have highly variable margins depending on the brand (ranging from 8% to 25%), the pharmaceutical industry operates on heavily standardized, regulated margins.
- Branded Ethical Medicines: Retailers universally receive a 20% margin on the base price.
- Generic Medicines: Margins are often much higher, ranging from 50% to 70%, depending on the manufacturing company’s direct schemes.
- OTC (Over The Counter) Pharma: Products like cough syrups or balms typically carry a 10% to 15% margin.
Why Accurate PTR Calculation Matters
Using a dedicated pharma billing calculator is essential for compliance. When filing GST returns (GSTR-1 and GSTR-3B), the government requires businesses to strictly report the “Taxable Value” (Base Price) and the “Tax Amount” as separate line items on B2B invoices. Guessing the PTR or calculating it as a flat discount off the MRP will lead to mismatches in your Input Tax Credit (ITC) ledger.
