Welcome to our Mathis Equation Throughput Calculator!

This tool is designed to help you estimate network throughput in the presence of packet loss, using the Mathis equation—a widely recognized formula for understanding how TCP performance is impacted by packet loss and round-trip time (RTT). 

Packet loss is a critical factor in network performance, as even small losses can significantly reduce throughput.

1,500 byte is the maximum transmission unit (MTU) for Ethernet networks and the average packet size on the internet is varies on usage, it can be anywhere between 20 and 1500 bytes. If you are unsure, pick 800 or try a few different sizes.
 

For typical users, packet loss rates can vary

  • Home networks generally experience packet loss below 1%, depending on ISP quality,  and network conditions - crowded Wi-Fi environments can drive this number up.
  • Public networks, such as Wi-Fi in cafes or airports, often have higher packet loss, ranging from 2% to 5% due to congestion and interference.

Use the calculator below to better understand how packet loss impacts your network’s performance and optimize your setup for smoother data transmission.
