What is latency and why does it matter?

Latency (also called ping) is the time in milliseconds for data to travel from your device to a server and back. High latency causes delays in video calls, lag in games, and slow-feeling remote desktop sessions. For video calls, latency should be below 150ms. For gaming, below 50ms.

Jitter measures how much your latency varies over time. Even if your average latency is good, high jitter means your connection swings between fast and slow, causing choppy video, audio glitches, and inconsistent gaming performance. Lower is better — below 30ms for calls, below 10ms for gaming.

Packet loss is the percentage of data that gets lost in transit and never arrives. Even 0.5% packet loss can cause visible problems in video calls and online games. It should be as close to 0% as possible.

How do I find my latency, jitter, and packet loss?

Run a test at speedtest.net or speed.cloudflare.com. Cloudflare shows all three metrics. You can also use the ping command in your terminal. Test at different times of day for the most accurate picture.

Does this tool use my download/upload speed?

No. This tool focuses on connection quality (latency, jitter, packet loss) rather than raw speed. Most UK households have enough download speed, but poor quality metrics cause the problems people actually notice — choppy video calls, lag in games, and slow remote desktop.

What does the peak-time simulation do?

It increases all your quality metrics by a percentage to simulate how your broadband performs during busy evening hours (7-11pm). UK broadband connections typically worsen by 15-40% during peak times, especially on older FTTC and ADSL connections.

How is the productivity risk score calculated?

The risk percentage is based on how your household uses broadband. Video call hours and remote desktop usage carry the most weight. If those activities score below 50% (meaning your metrics significantly exceed thresholds), your risk increases proportionally.

What should I do if activities are failing?

First, test with a wired Ethernet connection to rule out Wi-Fi problems. If quality is still poor, consider upgrading to FTTP (full fibre), switching provider, or improving your home network with a mesh system or QoS router settings.

Is gaming always the hardest to pass?

Yes. Online gaming has the tightest quality requirements — latency below 50ms, jitter below 10ms, and packet loss below 0.5%. Many UK broadband connections struggle with these during peak hours, especially on non-fibre connections.

How This Tool Works

📋 Purpose

Most broadband problems are not about speed — they are about quality. This tool tests your latency, jitter, and packet loss against the real requirements for video calls, gaming, remote desktop, and streaming. It then scores your overall productivity risk based on how your household actually uses broadband, including a peak-time simulation to check evening reliability.

⚙️ How It Works

1
Run a speed test and note your latency, jitter, and packet loss readings
2
Enter these values along with your household usage profile (concurrent users, call hours, activities)
3
The tool compares your metrics against published quality thresholds for each activity
4
Each activity gets a pass/fail result and a suitability score (0-100%)
5
Your overall productivity risk is calculated from a weighted combination of activity scores and usage patterns
6
Enable peak-time simulation to test how your connection holds up during busy evening hours

Why Speed Tests Alone Are Not Enough

Download speed only tells part of the story. For video calls, gaming, and remote work, three other metrics matter just as much: latency (delay), jitter (inconsistency), and packet loss (dropped data). This tool checks your connection against real activity requirements so you know whether your broadband truly supports your household needs.

Your Connection Quality

Enter your latency, jitter, and packet loss from a speed test. You can use sites like Speedtest.net or Cloudflare Speed Test to get these numbers.

Latency

Delay before data arrives. Lower is better. Typical: 10-80ms

Jitter

How much latency varies. Lower is better. Typical: 1-20ms

Packet Loss

Data lost in transit. Should be near 0%. Anything over 1% causes problems.

Postcode (optional — adds area speed context from Ofcom)

Your Household Usage

How your household uses broadband on a typical day

People using broadband at the same time

Include everyone who might be online at the same time — working, streaming, gaming, or browsing

Daily video call hours

Total hours of Teams, Zoom, FaceTime, or other video calls across all household members

Online Gaming

Peak-Time Simulation

Test how your connection performs during busy evening hours (typically 7-11pm)

Risk Level

Maximum acceptable values for each activity. If your reading is below the threshold, the activity passes.

Activity	Max Latency	Max Jitter	Max Packet Loss
Video Calls	150ms	30ms	1%
Online Gaming	50ms	10ms	0.5%
Remote Desktop	100ms	20ms	0.5%
Streaming	300ms	50ms	2%

Data Sources and How This Works

Your Inputs

All calculations use the connection quality values you enter — latency, jitter, and packet loss from a speed test. No personal data is stored or sent anywhere.

Activity Thresholds

The pass/fail thresholds for each activity are based on widely published guidelines from platform providers (e.g. Microsoft Teams, Zoom, PlayStation, Xbox) and industry standards for real-time communication quality. Video calls need latency under 150ms and jitter under 30ms. Gaming needs latency under 50ms and jitter under 10ms.

How Activity Scores Are Calculated

Each activity gets a suitability score (0-100%) based on how far your metrics are from the thresholds. If your latency is half the threshold, you score 50% for that metric. The overall score is the average of latency, jitter, and packet loss scores. A score above 0% means your reading is within the acceptable range.

How Productivity Risk Is Calculated

The risk percentage is a weighted calculation based on your household usage profile. Video call hours, gaming, remote desktop usage, and the number of concurrent users each contribute a weighted share. Activities with scores below 50% increase risk proportionally to how far below 50% they fall.

Peak-Time Degradation

When enabled, the simulator increases all your metrics by the degradation percentage you choose. This models how UK broadband connections typically worsen during evening peak hours (7-11pm). Ofcom reports that average speeds can drop by 15-30% during peak times, more on older copper connections.

Important Note

This tool is an estimation based on the values you enter and published quality guidelines. Actual broadband performance varies by provider, technology type (FTTP, FTTC, ADSL), local network conditions, and time of day. Run speed tests at multiple times for the most accurate picture.

Quick Tips

Jump-start your understanding with these essential tips

A test at 10am on Tuesday tells you very little about your connection at 8pm on Friday. Run tests at the times that matter most — during video calls, gaming sessions, or busy evenings. Use at least two different test sites for reliability.

A 100 Mbps connection with 120ms latency and 40ms jitter will give you worse video calls than a 30 Mbps connection with 15ms latency and 3ms jitter. This tool focuses on quality metrics because they determine whether activities actually work, not just how fast files download.

Wi-Fi adds latency, jitter, and packet loss on top of your actual broadband performance. To measure your broadband quality accurately, plug your computer directly into the router with an Ethernet cable. If the results are good wired but bad on Wi-Fi, the problem is your wireless setup, not your broadband.

UK broadband connections typically degrade by 15-40% during peak hours (7-11pm). Enable the peak simulation with 25-35% degradation to see if your activities still pass under realistic evening conditions.

If three people are on video calls while someone else is gaming, that is four concurrent users. Each person adds load. Set the concurrent users to the maximum number of people online at the same time for the most realistic risk assessment.

Step-by-Step Guide

Follow these steps to get the most from this tool

Run a speed test using Speedtest.net or Cloudflare Speed Test and note your latency (ping), jitter, and packet loss. Enter these values into the tool.

If your speed test does not show jitter or packet loss, try Cloudflare Speed Test — it reports all three metrics. You can also use the command ping -c 20 google.com on Mac/Linux to see latency variation.

💡 Pro Tips:

•Run tests at different times of day for a realistic picture.
•Use a wired connection for the most accurate readings.
•If you only have latency, set jitter to roughly 20-30% of your latency as a starting estimate.

Compare broadband speed vs price value

Tell the tool how your household uses broadband. Set the number of people typically online at the same time, daily video call hours, and whether anyone games or uses remote desktop for work.

The tool uses these settings to calculate a weighted productivity risk score. Video calls and remote desktop are weighted more heavily because they are most sensitive to quality problems.

💡 Pro Tips:

•Count everyone who might be online at the same time — not just workers.
•Include school/uni video calls, not just work calls.
•If you use cloud development tools (GitHub Codespaces, AWS Cloud9), enable Remote Desktop.

Toggle on the peak simulation and set the degradation percentage. Start with 25-30% for a typical UK broadband connection. If you regularly notice evening slowdowns, try 40-50%.

The simulator increases all your quality metrics by the chosen percentage. This shows you how each activity performs under realistic worst-case conditions.

💡 Pro Tips:

•FTTP (fibre to the premises) has less peak degradation — try 10-20%.
•FTTC (fibre to cabinet) and ADSL may degrade 30-50% during peak hours.
•If all activities still pass at 40% degradation, your connection is robust.

Check whether switching broadband saves money

Check the summary cards for your overall risk level and how many activities pass or fail. Use the activity cards to see exactly which metrics are causing problems.

If critical activities fail (video calls, remote desktop), your broadband quality may not be suitable for your needs. Consider upgrading to FTTP, changing provider, or improving your home network setup (better Wi-Fi router, Ethernet cables, mesh network).

💡 Pro Tips:

•Focus on failing activities that affect your daily work or study.
•If only gaming fails, it may be acceptable for a non-gaming household.
•Check whether a wired connection solves the problem before switching provider.

Advanced Topics

Deep dives for advanced users

A connection with consistently high latency (e.g. 80ms) is often more usable than one with low average latency but high jitter (e.g. 20ms average but swinging between 5ms and 60ms). This is because real-time applications like video calls buffer data based on expected timing — and inconsistent delivery causes choppy audio, frozen video, and dropped frames.

If your latency is acceptable but jitter is high, the problem is usually local contention (Wi-Fi interference, shared bandwidth) rather than your broadband line itself.

Compare broadband quality across price tiers

Download speed measures throughput — how much data can flow per second. Quality metrics (latency, jitter, packet loss) measure how reliably and consistently that data arrives. You can have 300 Mbps download speed but terrible video call quality if latency is 200ms.

Speed matters for large downloads and streaming resolution. Quality matters for anything interactive — video calls, gaming, remote desktop, live collaboration. This tool focuses on quality because most UK households have enough speed but may not have enough quality.

Before switching provider, try these fixes:

Use Ethernet cables for devices that need the best connection (work laptop, games console)
Move your router away from walls, microwaves, and cordless phones
Use a mesh Wi-Fi system if your home has dead spots
Enable QoS (Quality of Service) on your router to prioritise video calls
Check for firmware updates on your router
Reduce background downloads and cloud sync during important calls

If quality problems persist on a wired connection, the issue is your broadband line or provider network, and upgrading to FTTP or switching provider may be the best option.
