Minecraft Server RAM Calculator

Two questions, one honest answer — how much RAM your server actually needs, and the plan that fits it.

1 What will you run?

Vanilla Pure vanilla or snapshot survival Vanilla + Plugins Paper / Spigot with up to ~25 plugins Light Modpack ~50–100 mods (e.g. Fabric performance packs) Medium Modpack 100–200 mods (e.g. Better MC, Prominence II) Heavy Modpack 200–400+ mods — huge do-everything packs (e.g. All the Mods, RAD) Expert-Tier Pack Kitchen-sink giants — the biggest, heaviest packs there are (e.g. GT: New Horizons)

2 How many players online at once?

We’ll keep adding mods or plugins over time (adds headroom)

Recommended RAM —

This calculator needs JavaScript. No problem — as a rule of thumb: vanilla runs great on 3–4 GB, medium modpacks want 6–8 GB, and heavy packs like All the Mods want 10–16 GB. Browse all plans →

The honest print: these are recommendations for consistently smooth TPS — that’s your server’s frame rate, how smooth it feels — not requirements, and never hard caps. Player slots are unlimited on every plan, every plan can run any pack, and you can resize anytime as your community grows.

How we calculate it

Each server type has a fixed footprint (the world, loaded chunks, and the pack’s mod set) plus a per-player cost for the chunks, entities, and traffic every online player adds. Heavier packs both start bigger and grow faster per player — an expert-tier pack can idle above what a vanilla server needs at 20 players. We round up to the nearest GB and match you to the smallest plan that clears the recommendation, so you’re not paying for RAM you won’t use. That’s why $5/GB is fair — you buy exactly the RAM you need and not a gigabyte more.

Every plan runs on the same hardware — AMD EPYC cores, DDR5 ECC memory, and Gen4 NVMe storage — and every server is deployed and crash-supervised by our own MineXEngine, so the RAM you buy goes to your world, not to overhead.
