Calculateur de VPN Bandwidth Overhead
Estimate effective throughput after VPN encryption overhead.
Formula and method
This calculator computes Effective throughput directly in your browser without sending data to an external server.
Mathematical formula
- Effective throughput:
rawBandwidthMbps × (1-overheadPct ÷ 100)
Variables and parameters
- Raw bandwidth (rawBandwidthMbps): default value 100 Mbps.
- Estimated VPN overhead (overheadPct): default value 10 %.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
