Calculate Your Brand Medication Savings with InStockRx
Enter your monthly brand medication spend and surplus inventory value. This calculator estimates your potential savings buying below NADAC on InStockRx, and the cash you could recover selling surplus. Based on real outcomes: buying pharmacies save $91K/year on average; selling pharmacies recover $32,946/month on average.
See how much your pharmacy could save by sourcing short-dated or overstocked medications through InStockRx instead of paying full WAC.
Understanding Your Pharmacy's Brand Medication ROI
Brand medications sold on InStockRx come from verified independent pharmacies — not secondary wholesalers or gray market sources. Sellers list short-dated or surplus inventory they would otherwise write off. Buyers access those medications at prices benchmarked against NADAC, often 20–40% below wholesale acquisition cost (WAC). Because both parties are verified dispensers and every transaction includes automatic DSCSA T3 documentation, you get the savings without compromising compliance.
The $32,946/month average is based on InStockRx platform data from selling pharmacies who actively list surplus inventory. Your number will vary depending on your drug mix, volume, and how quickly your market turns. Pharmacies with higher brand medication dispensing volume and regular near-expiry inventory typically see the highest returns. The 9-day average listing sell time means most inventory moves before it becomes a write-off.
→ How to optimize pharmacy cash flow with surplus inventory
The $91K annual savings figure is based on buying pharmacies sourcing brand medications below NADAC versus ordering the same drugs through their primary wholesaler at or above WAC. InStockRx shows NADAC pricing on every listing so you can compare in real time. You only pay when you buy — there are no monthly fees, no subscription, and no minimum order requirements.
Is InStockRx Right for Your Pharmacy?
InStockRx works best for independent pharmacies that regularly stock brand medications and either carry surplus inventory or source fill-ins between distributor delivery days. If your pharmacy dispenses primarily generics or participates in 340B programs, the savings potential may be lower.
