Minecraft: Java Edition Server Calculator

RAM is the biggest factor, but CPU single-thread speed matters a lot too since Minecraft's main game loop runs on one core. Disk speed (NVMe vs HDD) affects chunk loading and world saves, and network quality determines latency for your players. The calculator sizes RAM and CPU for you; the rest comes down to your hosting provider or hardware.

Mods add new blocks, entities, world generation, and systems that all live in memory. A vanilla server with 10 players might run fine on 4GB, but a 200-mod pack like All The Mods can need 8–10GB just to load. The calculator accounts for your mod count and pack size to give you a realistic number, not a generic guess.

Yes, home hosting works well for small groups of friends. You'll need a stable internet connection, port forwarding, and a machine that can stay on. The trade-offs are uptime, latency for distant players, and security exposure. The calculator gives you the same hardware recommendations whether you host at home or with a provider, so you can compare costs directly.

Managed hosting (like EVLBOX game servers) handles setup, updates, and the control panel for you. You configure your world and play. A VPS gives you a full Linux machine with root access, which is more flexible but requires you to install and maintain the server software yourself. The calculator shows a VPS option if your setup would benefit from one.

Absolutely. Most hosting providers, including EVLBOX, let you upgrade your plan without losing your world or data. It's better to start with what the calculator recommends and scale up if you see lag or TPS drops, rather than overpaying from day one.

It uses the same sizing logic our support team relies on and accounts for your software, player count, mods, and play style. Real-world performance also depends on world size, redstone builds, and specific plugins, so treat the result as a strong baseline. If anything, it errs slightly generous so you have headroom.
