WAN Optimization Calculator

Calculate bandwidth and time savings from WAN optimization with compression and deduplication.

The total amount of unoptimized data to be transferred over the WAN link during the measurement period (per day or per transfer).
How much data is reduced by compression. A ratio of 2:1 means data is halved. Typical: 1.5:1 to 3:1 depending on data type. Text/office docs compress well; media does not.
:1
How much data is eliminated by deduplication (removing duplicate byte patterns). Typical: 2:1 to 10:1. Backup data can see 20:1+. First transfer sees minimal dedup.
:1
The actual WAN link bandwidth available for this traffic. This is the provisioned circuit speed.
Mbps
