Minecraft Server RAM Calculator
The best Minecraft server RAM calculator, estimating how much RAM Minecraft servers require to work, based on player base, plugins, configuration, and server version.
Minecraft server start.bat file
Use our script to automatically generate a start bat file for your Minecraft server, which helps optimizations and healthier tick rates. The script used is automatically calculated by our RAM resource calculator for Minecraft. This script is assisted by Aikar's Flags. It only works on the Paper jar. Additionally, you can find alternative server jars, if Paper does not suit you.
How to use our Minecraft RAM calculator
To calculate the amount of RAM for your server, simply choose the server version you are running, a player base that will be online, and the number of active plugins.
Based on your chosen criteria, you will receive an estimate of how much RAM you need to dedicate to your Minecraft server in order to run it smoothly.
Usually, Minecraft servers require at least 2GB of RAM for versions under 1.12. Newer versions require at least 4GB of RAM assigned. With these statistics set, we have outlined the specifications you need to know for creating a Minecraft server.

Frequently Asked Questions by Minecraft Server Owners
Can my computer run a Minecraft server?
Any computer can run and host a server, even the older ones. Our Minecraft server RAM calculator estimates the amount of RAM needed to host a server based on the number of players, plugins, and world size.
Is 1 GB of RAM good for a Minecraft server?
If you are playing older versions of Minecraft like 1.12 and below, 1GB of RAM is good for a server. However, versions 1.13 and above require at least 4GB to power up and use your server.
Is 1 GB of RAM good for a Minecraft server?
If you are playing older versions of Minecraft like 1.12 and below, 1GB of RAM would be enough. However, server versions starting from 1.13 and higher require at least 4GB to power up and use your server.
Do Minecraft servers need a multi-core CPU?
Minecraft servers require a CPU to be installed to operate. A single-threaded CPU from the Intel Celeron brand could handle plenty of player traffic, as it is designed for such purposes. And since Minecraft doesn’t use multi-threaded CPUs, you can easily invest in almost any budget CPU, rather than buying a gaming one.
Is 4GB RAM enough for a modded Minecraft server?
Modded Minecraft servers require more RAM than those using plugins. Using 4GB of RAM to run mods could keep your server playable. It strictly depends on what mods you wish to install, and the number of players connected at the same time.
The recommended starting RAM is between 4 and 6GB to keep your server in good health.
