VPS Size Calculator

Tick what you want to run. You get a RAM estimate with headroom and the smallest netcup VPS that covers it. The numbers are rough idle figures for typical Docker installs, so treat the result as a starting point, not a promise.

How the estimate works

  • Base system: about 0.4 GB for Debian or Ubuntu, Docker and a reverse proxy.
  • Apps: typical memory when idle or lightly used. Real use grows with data and users.
  • Headroom: +30%, so spikes and updates don't trigger the OOM killer.

Over budget? The RAM budget guide covers container limits, swap and log caps. Sizes and prices change, so confirm on the VPS voucher page, where each code links to the matching plan. Not sure about netcup? See netcup vs Hetzner vs Contabo.
