Network Latency Calculator
Analyze ping results to measure network latency. Paste raw ping output or a list of round-trip times to get mean, median, min, max, jitter, standard deviation, packet loss and an overall connection quality grade.

What does this calculator do?
Running ping gives you a stream of round-trip times, but reading raw output line by line tells you little about how good your connection really is. This tool parses that output and turns it into the numbers that actually matter for latency-sensitive work like gaming, video calls and VoIP:
- Ping count — how many replies were measured.
- Mean, median, min, max and range — the average round-trip time and how much it swings.
- Standard deviation — how spread out the times are around the average.
- Jitter — the average difference between consecutive pings (packet delay variation). Low jitter matters more than low latency for real-time audio and video.
- Packet loss — the percentage of packets that never came back.
- Quality grade — an overall Excellent / Good / Fair / Poor rating combining latency, jitter and loss.
How to use it
- Run a ping in your terminal, e.g.
ping -c 20 google.com(macOS/Linux) orping -n 20 google.com(Windows). - Copy the whole output and paste it into the Ping Data box. The tool auto-detects round-trip times and the packet-loss summary line from Linux, macOS and Windows.
- Alternatively, paste a plain comma- or space-separated list of times (e.g.
12.3, 14.1, 11.8, 45.2). - If your input has no packet-loss line, optionally fill in Packets Sent and Packets Received to compute loss.
- Read the result table — it updates as you type, and can be copied or downloaded as CSV.
How is the quality grade decided?
The grade is the worst rating triggered by any single metric, so one bad dimension pulls the whole score down:
- Poor — packet loss over 10%, mean latency over 200 ms, or jitter over 50 ms.
- Fair — packet loss over 5%, mean over 100 ms, or jitter over 30 ms.
- Good — packet loss over 1%, mean over 50 ms, or jitter over 15 ms.
- Excellent — everything below those thresholds.
Latency vs. jitter — what's the difference?
Latency (round-trip time) is how long a packet takes to make the trip; jitter is how inconsistent that time is from one packet to the next. A connection with a steady 60 ms latency feels smoother on a call than one that bounces between 10 ms and 90 ms even though the second has a lower minimum — the variation causes audio dropouts and rubber-banding in games. That's why this tool reports jitter alongside the average.
Which standard deviation is used?
The population standard deviation (dividing by n, not n−1) is used, treating the pings you paste as the complete set being measured rather than a sample of a larger population.
