Introduction: What is a PTR PST Calculator?
A PTR PST Calculator is an essential tool for pharmaceutical companies, stockists, distributors, and retail chemists in India. It converts the Maximum Retail Price (MRP) of a medicine into the two most important trade prices used in the pharma distribution chain: PTR (Price to Retailer) and PTS (Price to Stockist).
Unlike a simple percentage calculator, a proper PTR PTS calculator accounts for the fact that MRP already includes GST. So the retailer margin and stockist margin must be calculated on the GST-inclusive value of the drug, not on the taxable value. This tool does exactly that — instantly and without any manual error.
What is PTR (Price to Retailer)?
PTR is the price at which a pharmaceutical stockist or distributor sells a medicine to a retail chemist. It is the rate the retailer pays to buy the stock — and the difference between MRP and PTR is the retailer’s margin (typically 20% in India). PTR is usually quoted GST-inclusive, but distributors also work out the GST-exclusive PTR for accounting and input credit purposes.
What is PTS (Price to Stockist)?
PTS is the price at which a pharma company sells a medicine to a stockist or clearing & forwarding agent (C&F). The difference between PTR and PTS is the stockist’s margin (typically 10% in India). PTS is also quoted GST-inclusive in most trade schemes, with a GST-exclusive value used for invoicing.
Standard Pharma Margins in India (2026)
| Trade Level | Standard Margin | Notes |
|---|---|---|
| Retailer (Chemist) | 20% | On GST-inclusive MRP |
| Stockist / Distributor | 10% | On GST-inclusive PTR |
| Company (Manufacturer) | Balance | Determined after margins + GST |
Some companies run aggressive trade schemes where retailer margins go up to 25–30% and stockist margins up to 12–15%. Use the Advanced: Custom Margins section in the calculator to model those.
PTR PTS Formula (GST-Inclusive & GST-Exclusive)
PTS (GST-inclusive) = PTR ÷ (1 + Stockist Margin %)
PTR (GST-exclusive) = PTR (incl) ÷ (1 + GST %)
PTS (GST-exclusive) = PTS (incl) ÷ (1 + GST %)
Worked Example
Suppose a medicine has MRP = ₹120, GST = 5%, retailer margin = 20%, stockist margin = 10%:
- PTR (GST-inclusive) = 120 ÷ 1.20 = ₹100.00
- PTS (GST-inclusive) = 100 ÷ 1.10 = ₹90.91
- PTR (GST-exclusive) = 100 ÷ 1.05 = ₹95.24
- PTS (GST-exclusive) = 90.91 ÷ 1.05 = ₹86.58

Frequently Asked Questions (FAQ)
What is the difference between PTR and PTS?
PTR is the price a stockist charges a retailer. PTS is the price a company charges a stockist. PTS is always lower than PTR because the stockist needs to earn a margin on the difference.
Is PTR GST-inclusive or GST-exclusive?
In trade practice, PTR is usually quoted GST-inclusive. But for accounting and GST returns, you also need the GST-exclusive PTR. Our calculator shows both values.
How is PTR calculated from MRP?
PTR = MRP ÷ (1 + Retailer Margin %). For example, with MRP ₹120 and retailer margin 20%, PTR = 120 ÷ 1.20 = ₹100.
What is the standard retailer margin in Indian pharma?
The standard retailer margin is 20% on the GST-inclusive MRP. Some schemes may offer up to 30% for high-value products.
What is the standard stockist margin in Indian pharma?
The standard stockist (distributor) margin is 10% on the GST-inclusive PTR. Some companies offer 12–15% for high-volume buyers.
Which GST rate applies to medicines in India?
Most medicines fall under the 12% GST slab in older classifications, but the current applicable rates relevant to this calculator are 5% (life-saving drugs and specified formulations) and 18% (other formulations and nutraceuticals). Always confirm the rate on your supplier invoice or the CBIC HSN list.
Can I use this calculator for Ayurvedic or nutraceutical products?
Yes — simply select 18% for most nutraceuticals and check your invoice for Ayurvedic products. The margin structure remains the same.
