Free online bandwidth calculator. Calculate bandwidth requirements for RDP, video streaming, Zoom, gaming, and VoIP. Calculate data transfer time and convert Mbps, MB/s, Gbps units.
The Network Bandwidth Calculator helps you plan the internet or network bandwidth you need for RDP sessions, video streaming, Zoom/Teams meetings, online gaming, IP cameras, and VoIP calls. Enter the number of concurrent users for each service and get an instant recommendation with a 20% safety buffer.
For a team of 10 doing standard office work over RDP (5 Mbps each): 10 x 5 Mbps + 20% buffer = 60 Mbps minimum. For multimedia-heavy RDP sessions, budget 15 Mbps per user. Multi-monitor 4K setups require 40+ Mbps per user.
Transfer Time (seconds) = (File Size in GB x 1024 x 8) / Speed in Mbps. Example: 100 GB over 1 Gbps = (100 x 1024 x 8) / 1000 = 819 seconds (about 13.7 minutes). Over 10 Gbps Ethernet: 81.9 seconds.
1 Mbps = 1,000 Kbps = 0.001 Gbps. 1 MB/s = 8 Mbps. 1 GB/s = 8 Gbps. A 100 Mbps connection transfers files at 12.5 MB/s theoretical maximum.
RDP bandwidth depends on resolution and activity. Standard 1080p office work: 5 Mbps/session. Multimedia: 15 Mbps/session. Multi-monitor 4K: 40 Mbps/session.
Netflix HD = 5 Mbps, 4K = 25 Mbps per stream. For 10 HD streams: 10 x 5 + 20% buffer = 60 Mbps minimum.
Time (seconds) = (Size_GB x 1024 x 8) / Speed_Mbps. A 10 GB file at 100 Mbps: (10 x 1024 x 8) / 100 = 819 seconds (~13.7 minutes).
Mbps = megabits per second (network speed). MB/s = megabytes per second (file transfer rate). Since 1 byte = 8 bits: 1 MB/s = 8 Mbps. A 100 Mbps link = ~12.5 MB/s.
