Disk Space and Bandwidth Overage Billing Calculation Clarification

Hi,

I've read through the Disk Space and Bandwidth Overage Billing article, but I still find the calculations portion still a bit unclear. I would recommend adding 1 or 2 sample calculations to the documentation as well.

For example, I have a package with 1GB Disk Space and 2GB Bandwidth.

I charge $2 per GB (overage on either Disk Space or Bandwidth) or any part thereof.

So as example 1, the client used 2.1GB Bandwidth for the month, we would charge them $2 overage for the month since the 0.1 pushes the client over his current 2GB Bandwidth

Example 2: the client used 1.5GB Disk Space and 3.9GB Bandwidth, which is 0.5GB over on Disk Space and 1.9GB over on Bandwidth, we would charge him $6 (1x overage on Disk Space and 2x overage on Bandwidth)

How do I go about to set this up on my product on WHMCS to calculate the correct overage charges?

Thanks in advance.
