This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own Bloody Ragdoll Physics 🩸 session. It will not click the shop.
Material planner
Kill gate left
Enter the kill gate of the weapon you want and the kill count already on your weapons panel. The result is how many more kills that one gate still needs. It does not add gates together, estimate time, or invent a Robux price.
Required total = materials per upgrade × number of upgrades. Missing = max(required total − materials already owned, 0).
Gates are cumulative thresholds, not stacked costs. Kills still needed equals the target gate minus the kill count shown on the weapons panel. Shared gates unlock together: Katana and Throwing Knives at 200, Axe and Grenade at 250. Balloon has no printed Robux price. Cards whose price was not shown on the panel are marked earn-only. Gates were read from the weapons panel on 13 November 2026. The official description also names a minigun, rocket launcher, flamethrower, gravity gun and a black-hole weapon that were not on the tabs that were read; do not use this form for those.
