Packet Loss Impact Calculator

Estimate TCP throughput degradation caused by packet loss (Mathis formula).

Packet Loss (%)

RTT (ms)

Link Speed (Mbps)

Effective Throughput2.34 Mbpsof 100 Mbps (2.3% efficiency)

0.01% loss23.36 Mbps23.4%

0.1% loss7.39 Mbps7.4%

0.5% loss3.30 Mbps3.3%

1% loss2.34 Mbps2.3%

2% loss1.65 Mbps1.7%

5% loss1.04 Mbps1.0%

Uses the Mathis formula: Throughput ≈ MSS / (RTT × √p). Even 1% packet loss can cause significant throughput drops.
