What is the difference between bandwidth and throughput?

Bandwidth is the maximum theoretical capacity of a network link, while throughput is the actual amount of data that is successfully transferred over that link in real-time, accounting for overhead and congestion.

Why does my actual download speed not match the bandwidth calculation?

Actual speed is often lower due to protocol overhead (TCP/IP headers), network congestion, hardware limitations, and latency (RTT) which affects the TCP window size.

How do I convert Megabits (Mbps) to Megabytes (MB/s)?

Since there are 8 bits in a byte, you divide the Mbps value by 8. For example, 100 Mbps / 8 = 12.5 MB/s.

Does the Bandwidth Calculator account for packet loss?

While basic calculators focus on capacity, our advanced tool allows you to factor in a percentage of overhead, which can be used to simulate the impact of packet retransmission.

What is the Bandwidth-Delay Product (BDP)?

BDP is the product of a data link's bandwidth and its round-trip delay. It represents the maximum amount of data that can be in transit on the network at any given time.

Is my data secure when using this online calculator?

Yes, the calculator performs all operations on the client-side using JavaScript, meaning your input data never leaves your browser and is not stored on any server.

Bandwidth Calculator — RDP, Streaming, Data Transfer & Unit Converter

Network Bandwidth Calculator

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.

Bandwidth Requirements by Service

Video Streaming (Netflix/YouTube): SD 480p = 3 Mbps, HD 1080p = 5 Mbps, 4K = 25 Mbps per stream
RDP Remote Desktop: Light use = 1 Mbps/user, Standard 1080p = 5 Mbps/user, Multimedia = 15 Mbps/user, Multi-monitor 4K = 40 Mbps/user
Video Conferencing (Zoom/Teams): HD 720p = 1.5 Mbps, Full HD 1080p = 3.8 Mbps per participant
Online Gaming: Standard = 5 Mbps, Cloud gaming 1080p = 20 Mbps
VoIP Calls: Standard G.711 = 100 Kbps/call, HD voice = 320 Kbps/call
IP Cameras: 1080p = 4 Mbps/camera, 4K = 16 Mbps/camera

RDP Bandwidth Calculator

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.

Data Transfer Time Formula

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.

Bandwidth Unit Converter

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.

Frequently Asked Questions

How much bandwidth does RDP use?

RDP bandwidth depends on resolution and activity. Standard 1080p office work: 5 Mbps/session. Multimedia: 15 Mbps/session. Multi-monitor 4K: 40 Mbps/session.

How do I calculate bandwidth for video streaming?

Netflix HD = 5 Mbps, 4K = 25 Mbps per stream. For 10 HD streams: 10 x 5 + 20% buffer = 60 Mbps minimum.

What is the formula for data transfer time?

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).

What is the difference between Mbps and MB/s?

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.
