Convert sustained or average network throughput into an estimated volume of transferred data over a chosen operating schedule. The calculator combines average Mbps, active hours per day, number of days, and an optional utilization factor to show how quickly a connection can accumulate gigabytes or terabytes of traffic.
It is useful when comparing ISP data caps, estimating WAN or cloud-egress volumes, sizing logging or transfer budgets, and translating a bandwidth measurement into a more intuitive data quantity. Because traffic is rarely constant, the quality of the result depends heavily on whether the entered Mbps value represents a realistic average during the active period.
1. Enter average throughput
Use the Mbps rate observed or expected during active transfer periods.
2. Set active hours
Enter how many hours per day traffic runs at roughly that average rate.
3. Choose the period
Set the number of days covered by the estimate.
4. Adjust utilization
Use 100% if the Mbps input is already a true average; lower it if the input is closer to a peak or nominal rate.
5. Review data volume
The result is shown in decimal GB and TB, using 1 GB = 1,000 MB.
Dividing by 8 converts megabits to megabytes. Dividing by 1000 converts MB to decimal GB. This is a transfer-volume estimate and does not add protocol-specific overhead separately.
The result estimates the amount of payload-equivalent traffic implied by the entered average rate and schedule.
If the rate varies materially by hour or day, calculate separate periods and add them for a better estimate.
Given: 100 Mbps, 8 active hours per day, 30 days, and 60% utilization.
Calculation: Effective rate = 100 × 0.60 = 60 Mbps. Data = 60 × 8 × 30 × 3600 ÷ 8 ÷ 1000 = 6,480 GB.
Result: 6,480 GB, or 6.48 TB, over the 30-day period.
Bandwidth is a rate. Even a moderate sustained rate accumulates a large data volume when it runs for many hours.
Use 100% when the Mbps input already represents the actual average. Use a lower percentage when the input represents a maximum or nominal rate that is not continuously reached.
This calculator uses decimal networking units: 1 GB = 1,000 MB and 1 TB = 1,000 GB.
Not necessarily. Providers may meter traffic differently, count both directions, or use other unit conventions.
Bandwidth describes transfer rate, usually in bits per second. Data usage describes the accumulated amount transferred over time.
