Packet Loss Impact Calculator

Calculate application performance impact from network packet loss

Percentage of packets lost in transit. Even 0.1% can significantly impact TCP throughput.
%
Different applications react differently to packet loss. VoIP degrades quality; TCP reduces throughput via congestion control.
Network round-trip latency. LAN: 1-5ms, Metro: 5-20ms, Cross-country: 40-80ms, International: 100-300ms.
ms
Available bandwidth of the network link in Mbps.
