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 × 0.1GB)
+ 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.

0.1GB per player

Each connected player loads chunks around them and adds entities, inventories, and activity. About 0.1GB per player — roughly 1GB for every 10 players — 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.

Why hosts often recommend more

If a hosting company's own "recommended plan" tool suggests more RAM than we do, remember: a bigger plan earns them more money. Our number targets smooth, lag-free performance with sensible headroom — not the biggest possible sale. If you expect heavy activity, rounding up one tier is always safe.

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.
