How would linode charge me if I create a VPS and delete it after a few days before complete billing month?

(Not staff)
The charge for the vps is per hour. The cheapest Linode is $5/month but the $5 in this example is the estimated bill if you kept the Linode for the entire month. If you deleted that a few days before the bill would be something like $4.58 (not exact).
