FAQ
How much does a Hetzner CPX31 cost per month?
A CPX31 starts at €17.49/mo net (cheapest EU location) — about €0.03/hour. With backups enabled it's ~€20.99/mo, plus VAT and any traffic over the 21.99023255552 TB included.
What's included in the CPX31 price?
The flat rate includes the 4 vCPU / 8 GB RAM / 160 GB NVMe instance and 21.99023255552 TB of outbound traffic. Extra traffic is €1.00/TB. Backups add 20%. Volumes, extra IPs and load balancers are billed separately.
Is the CPX31 billed hourly or monthly?
Hourly, capped at the monthly rate — but Hetzner bills a full hour the moment a server exists, so a server alive for two seconds still costs one billed hour. HCM books spend the same way, so short-lived/autoscaled servers are counted correctly.
Why is my CPX31 bill higher than €17.49?
The sticker price is the base rate at the cheapest EU location. US locations cost ~3× more, and backups (+20%), traffic overage, volumes and IPs all add up. HCM shows your true per-resource spend so there are no surprises.
