About
CoC Medals Calculator is a lightweight, browser-based planning tool designed to help Clash of Clans players make informed decisions when spending their medals. Whether you're managing Clan War League (CWL) medals or Event medals, this calculator helps you plan purchases, track spending, and optimize your medal allocation across dozens of available items with different costs and stock limits.
One of the standout features is the gem optimization functionality. For players who prefer to convert medal purchases into gems, the tool uses an advanced knapsack algorithm to automatically suggest the best combination of items that maximizes total gem sell value within your remaining medal budget. This feature respects all stock limits and never removes items you've already added—it only suggests additional purchases.
Privacy and security are fundamental: everything runs entirely in your browser with no server-side processing, no data collection, and no connection to your Supercell account. You manually enter your medal count, and all calculations happen locally on your device. The interface is intuitive—simply enter your starting medals, tap items to add them to your cart, and watch as remaining medals update in real-time.
This is a fan-made tool and is not affiliated with, endorsed by, or sponsored by Supercell. It's built for the Clash of Clans community and is regularly updated to reflect changes in the game's medal shops, including new items, updated costs, and revised stock limits.
