How do I calculate data transfer when exceeding 1TiB?

IP ServerOne’s network bandwidth/data transfer is provided for FREE for the first 1 TiB of usage and is refreshed every month.

However, if your usage exceeds this amount, the subsequent charges are as follows:

1 TiB ~ 10 TiB || MYR 0.44 per GiB
10 TiB ~ 50 TiB || MYR 0.31 per GiB
50 TiB onwards || MYR 0.30 per GiB

Note: The usage boundaries are measured in TiB (tebibytes), but the charges are calculated per GiB (gibibytes).
1 TiB (tebibyte) = 1024 GiB (gibibytes).
