How to use the calculator
- Choose I know the MRP (most common) or I know the PTS to work backwards to the MRP.
- Type the price, pick the GST rate (5% for most medicines under GST 2.0) and set your margins.
- Read PTR and PTS on the right. Use the batch box to price a whole price list and download it as CSV.
PTR and PTS formulas
| Step | Formula | Example (MRP ₹100, GST 5%) |
|---|---|---|
| MRP without GST | MRP ÷ (1 + GST%) | 100 ÷ 1.05 = ₹95.24 |
| PTR | MRP without GST × (1 − retailer margin%) | 95.24 × 0.80 = ₹76.19 |
| PTS | PTR × (1 − stockist margin%) | 76.19 × 0.90 = ₹68.57 |
| Retailer pays | PTR × (1 + GST%) | 76.19 × 1.05 = ₹80.00 |
Margin on price vs markup on cost
Most pharma companies quote margins as a percentage of the price the margin-taker sells at. A 20% retailer margin means the retailer keeps 20% of the MRP (without GST). Some businesses calculate margin as a markup on what they pay instead, so a 20% markup on PTR. The two give different PTRs for the same number, so the calculator lets you choose under How margins are calculated.
| MRP ₹100, 5% GST, 20% / 10% | On selling price | Markup on cost |
|---|---|---|
| PTR | ₹76.19 | ₹79.37 |
| PTS | ₹68.57 | ₹72.15 |
GST 2.0 and medicine prices
Since 22 September 2025 most medicines are taxed at 5%, and a list of lifesaving medicines is at nil. If a product’s GST rate changed, its MRP without GST changed too, and so do PTR and PTS for the same printed MRP. Re-run your price list with the new rate to see the difference.
