How We Calculate
Minecraft Server RAM

No black box. Here's the exact formula behind every number on this site.

Total RAM = 2GB base
+ (players × 0.05GB)
+ server-type modifier
(rounded up)

The 2GB base

Every server needs memory just to boot the Java runtime, load the world spawn, and keep the core game running before a single player joins. 2GB is a safe, lag-free floor for a modern version.

0.05GB per player

Each connected player loads chunks around them and adds entities, inventories, and activity. Roughly 50MB per player is a reliable rule of thumb for typical survival play.

Server-type modifier

Plugins and mods load extra content into memory. The heavier your setup, the more you add:

Server typeAdds
Vanilla+0.0GB
Paper/Spigot+0.5GB
Light Mods+1.5GB
Heavy Mods+4.5GB

Why we round up

Running out of RAM causes far worse lag than having a little spare, and hosts sell whole-GB plans anyway. Rounding up to the next whole gigabyte gives you safe headroom for activity spikes.

Caveats

This is a well-calibrated estimate, not a guarantee. A very high view distance, huge redstone builds, hundreds of plugins, or a massive pre-generated world can push you higher. When in doubt, give a little extra.
