Packet Loss Ratio Formula

The following formula is used to calculate the packet loss ratio for a given number of lost packets and total number of sent packets.

PLR = (L / T) * 100

Variables:

  • PLR is the packet loss ratio (%)
  • L is the number of lost packets
  • T is the total number of sent packets

To calculate the packet loss ratio, divide the number of lost packets by the total number of sent packets. Multiply the result by 100 to get the percentage.

What is Packet Loss Ratio?

Packet loss ratio (PLR) is a measure of the number of data packets that are lost during transmission over a network. It is expressed as a percentage of the total number of packets sent. Packet loss can occur due to various reasons such as network congestion, hardware failures, or signal interference. High packet loss ratios can lead to degraded network performance, resulting in slower data transfer rates, increased latency, and poor quality of service for applications such as VoIP, video streaming, and online gaming.

How to Calculate Packet Loss Ratio?

The following steps outline how to calculate the Packet Loss Ratio.


  1. First, determine the number of lost packets (L).
  2. Next, determine the total number of sent packets (T).
  3. Next, calculate the packet loss ratio using the formula PLR = (L / T) * 100.
  4. Finally, calculate the Packet Loss Ratio.
  5. After inserting the values and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Number of lost packets (L) = 50

Total number of sent packets (T) = 1000
