How much RAM and vCPU for your server?

Enter your game, the number of players and what you plan to install: the tool works out the memory, cores and disk you need, explains where each figure comes from, then shows the matching plan. Prices come live from our catalogue. The result also indicates the matching VPS range if you prefer to host it yourself.

How these figures are calculated

No calculator replaces a measurement on your own server: two FiveM servers with the same number of players can use up to three times as much depending on the quality of their scripts. The rules below start from consumption observed on our machines and include a safety margin.

Game	Base	Per player	What weighs the most
FiveM	2 GB	+80 MB	The roleplay framework and the number of resources: a complete ESX or QBCore server starts at 6 GB before the first player.
Minecraft	1.5 GB	+70 MB	View distance, world pre-generation and mods: a modpack needs 3 to 6 GB more than a standard server.
Rust	4 GB	+60 MB	Map size and above all player buildings, which make memory grow until the next wipe.
Nova Life	2 GB	+70 MB	Job scripts and the character database.

On the processor side, all these games run their main loop on a single core: frequency matters more than the number of cores. Extra cores serve the database, the panel and backups. For disk, allow for the game, backups and logs: Rust is by far the hungriest.

Frequently asked questions

What you need to know

How much RAM for a 64-player FiveM server?

About 8 GB with optimised resources, and 12 to 16 GB for a complete roleplay server with many custom vehicles, clothes and maps. Processor speed matters as much as memory.

How much RAM for a 20-player Minecraft server?

About 4 GB with a few plugins and 8 GB for a modpack. The calculator adjusts the figure according to what you install.

Does the calculation also work for a modded Minecraft server?

Yes, choose the modpack type: modpacks need much more memory than a plugin server, often 6 to 10 GB for a handful of players, because each mod loads its own data at startup.

Should I choose more cores or a faster processor?

A faster processor. In all these games, the world simulation runs on a single core: four fast cores are better than twelve slow ones. Extra cores serve the database, the panel and side tasks.

What happens if my server is undersized?

Memory runs out first: the server starts using the disk as memory, response times collapse and the system may eventually kill the process. On the processor side, players notice lag and teleporting. It is better to start slightly above and scale down later.

Is this calculator free?

Yes, with no sign-up and no account. Everything is calculated in your browser, and nothing is sent to our servers.
