In our public community, we aim to answer open questions about anything SysAdmin, DigitalOcean and beyond. However, we make every attempt to keep personal information safe and so don’t ever access personal account information here. This means we can’t provide help with any account or billing-related issues.
Digital Ocean charges by the hour for all droplets. The cost per hour is dependent on the hardware tier you select when creating a droplet and whether you decide to add the backup option enabled. Also please note that at minimum $0.01 is charged even if you use the lowest tier for even a minute as that’s the lowest that can be billed for. However Digital Ocean sets a cap on expenses for each tier.
Hope that helps!
