Tell us your game, player count, and map size. We'll calculate exact RAM, CPU, storage, and bandwidth requirements — and match you to the right Hostinger KVM VPS plan. Takes 5 seconds.
The defaults are tuned for a typical community server. Adjust to match your setup.
The numbers come from real server operator data — not vendor marketing. We collected reported usage from subreddits, Pterodactyl/AMP community logs, Facepunch's official Rust docs, Mojang's Minecraft server notes, and Wildcard's ARK requirements.
For each game, we use this formula:
required_ram = base_ram + (ram_per_slot × slots)
required_cpu = base_cpu + (cpu_per_slot × slots)
final_ram = required_ram × world_multiplier × mods_multiplier
final_cpu = required_cpu × world_multiplier × mods_multiplierMultipliers are conservative (we round up, never down). If the calculator says you need 14 GB, we recommend 16 GB because game servers hitting 100% RAM means rubberbanding, chunk loading stalls, and rollbacks. The marginal cost of one plan tier up is almost always worth it.
This calculator is for Linux servers. Windows Server on the same hardware typically needs ~20% more RAM for the OS itself — add a tier if you're running Windows.

Self-managed VPS is cheapest, but you're installing SteamCMD, configuring systemd, and patching the OS yourself. If you want one-click game server deploys with no terminal, managed hosting is the better fit.
For FiveM and RedM, the best managed option is ZAP-Hosting — they're an official Cfx.re partner. Use voucher Keishin-a-8710 for 20%% off permanently.
For console cross-play (ARK Xbox, Palworld cross-play, Bedrock Realms alternative), use Nitrado — they're the only host with official console game-server partnerships.
For budget Minecraft with one-click modpacks and Multicraft panel, Shockbyte is the cheapest credible option.
A Paper or Purpur Minecraft server with 50 players on a medium world needs 6-8 GB RAM allocated to Java, which means the VPS should have at least 8 GB total so the OS has headroom. Hostinger KVM 2 fits this exactly. If you're adding 10+ plugins or a small modpack, step up to KVM 4.
Rust keeps the entire procedurally-generated map in RAM at all times: every tree, barrel, building, and player entity. A 3500-size map uses about 8-10 GB just sitting idle. Facepunch's own documentation recommends 12 GB minimum for a small server — our calculator bumps that up with a safety margin because Rust crashes hard when it hits the RAM ceiling.
No. Shared hosting (the cheap ~€2/month plans) doesn't give you SSH, root access, or the ability to bind custom ports — all of which are mandatory for a game server. You need a VPS (virtual private server) like Hostinger's KVM line, or a managed game server from ZAP/Nitrado/Shockbyte.
The calculator assumes Linux. Windows Server needs ~20%% more RAM for the OS itself. If you're running Windows, add one plan tier. See our Windows game server guide for details.
Yes. Hostinger supports in-place VPS upgrades — you click "upgrade" in hPanel, pay the prorated difference, and the VPS reboots on new hardware within 5-10 minutes. Your data and configuration are preserved. Start small and upgrade when you hit 80%% RAM.
Honestly? Don't underprovision. A Rust server that crashes every 6 hours because RAM hits 100%% will lose your playerbase in a week. If KVM 4 is out of budget for Rust, consider a managed host with a per-slot pricing model (ZAP-Hosting scales from ~€5/month for small servers), or reduce your map size and slot count until the numbers drop to KVM 2.
