ResultPlanned capacity: 13.44 TB

Projected logical data: 5,600 GB.

2 storage copy/copies plus 20% headroom.

Capacity-planning assumptions

Results use decimal storage units: 1 GB is 1,000 MB and 1 TB is 1,000 GB. Actual encoded bitrate can vary by scene, codec, quality settings, metadata, snapshots, filesystem overhead, retention policy, and provider behaviour. Keep operational reserve beyond the mathematical estimate.

How to use this calculator

  1. Enter the labelled values and review the live result.
  2. Review the live result and use Copy result when you need to share it.

How the calculation works

Monthly growth is added over the planning period, multiplied by stored copies, then capacity headroom is applied.

Formula

Monthly growth is added over the planning period, multiplied by stored copies, then capacity headroom is applied.

Step-by-step calculation

  1. Enter the labelled values and review the live result.
  2. Monthly growth is added over the planning period, multiplied by stored copies, then capacity headroom is applied.
  3. Check the displayed result, then copy it if needed.

Worked example

2 TB growing by 150 GB monthly for 24 months with two copies and 20% headroom needs 13.44 TB.
