Price changes on your VPS invoice can have a few different causes:

Common reasons for a price increase:

• Location fee adjustment — Some data center locations carry an additional regional fee that may be added or updated.
• VAT adjustment — Changes in applicable tax rates can affect the final invoice amount.
• Base price increase — Occasionally, Contabo adjusts the price of VPS plans themselves. These changes are always announced in advance via newsletter. Please check your email (including the spam folder) for prince increase updates.

If you received a newsletter before the change appeared on your invoice, the increase will have been explained there.
