Measured speed versus plan
Internet speed vs advertised speed test
Compare repeated browser measurements with the advertised and typical values on your internet plan. See the median, range, attainment rate, excluded runs, and every evidence caution before contacting support.
Test what your internet plan delivers
Run a full-capacity measurement, then compare eligible saved runs with the advertised and typical values on your plan.
Optional context is saved with recent results and included only if you copy a share link.
Full-capacity measurement
Active because you selected full-capacity mode. The time- and byte-bounded run requests at most about 832 MiB of test payload, and usually less. Protocol overhead may add a little more.
Test endpoint
Default Server - Nearest Location
Same-origin hosted endpoint
Endpoint readiness unavailable
Default endpoint is ready.
For plan evidence, prefer Ethernet, pause unrelated traffic, record the provider, and repeat across more than one date.
Two different reference values
Keep advertised speed and typical speed separate
A US Broadband Consumer Label lists pricing plus typical download, typical upload, and typical latency. Those values are distinct from a maximum advertised plan speed. The audit preserves both references instead of quietly substituting one for the other.
Advertised plan
Enter the download and upload speed used to identify or sell the plan. Treat it as a user-supplied reference, not an automatically verified entitlement.
Label typical performance
Enter typical download, upload, and latency exactly as the label shows them. Outside the US, use the equivalent contract or regulator disclosure when available.
Measured browser sample
The test includes the device, local network, browser, internet route, and selected endpoint. It does not directly measure only the access line.
Versioned method 1.0
Exact aggregation and reporting rules
Only locally measured runs with full download and upload transfer confidence enter the median. Editable shared values and incomplete or degraded transfer runs remain visible but are excluded. The bands below describe the selected sample; they do not decide a contract or regulatory question.
| Descriptive band | Minimum | Maximum | Meaning |
|---|---|---|---|
| At or above the entered reference | ≥ 100% | No upper bound | The sample aggregate equals or exceeds the speed value entered by the user. |
| Within 10% below the entered reference | ≥ 90% | < 100% | The sample aggregate is below the entered value but no more than 10% below it. |
| More than 10% below the entered reference | ≥ 0% | < 90% | The sample aggregate is more than 10% below the entered value. This descriptive band is not a legal or regulatory compliance threshold. |
Single snapshot
One eligible measured run. Useful for orientation, not for consistency.
Repeated sample
Two or more eligible runs that do not yet satisfy every stronger-sample check.
Stronger repeated wired sample
6+ eligible Ethernet runs across 2+ UTC dates and 6+ hours, with one consistent provider label.
Repeatable collection protocol
Build evidence before contacting support
1. Preserve the plan record
Save the plan label, date, base price, advertised values, typical values, and a bill without publishing account details.
2. Control the local path
Use Ethernet when possible, pause unrelated traffic, and keep the same capable device and test endpoint.
3. Repeat across time
Collect multiple eligible runs across more than one date. Keep low results instead of deleting inconvenient observations.
4. Export with limitations
Download JSON or CSV, preserve the generated summary, and state that the evidence is a browser sample rather than a certified line test.
Primary evidence
Sources behind the workflow
The interface separates provider disclosures from browser measurements and emphasizes repetition because the underlying sources do the same.
Federal Communications Commission
Broadband Consumer Label requirements
Broadband labels disclose price, typical download speed, typical upload speed, and typical latency.
Federal Communications Commission
Eleventh Measuring Broadband America Fixed Broadband Report
The program uses repeated measurements and reports aggregate download, upload, latency, and loss results rather than treating one observation as representative.
Internet Engineering Task Force
RFC 2330: Framework for IP Performance Metrics
Defines repeatability and careful methodology as core properties of useful network measurements.
Frequently asked questions
Internet speed versus plan questions
- How do I check whether I get the internet speed I pay for?
- Enter the advertised download and upload values from your plan, add the separate typical values from its Broadband Consumer Label when available, and compare several eligible measured runs. Prefer Ethernet, pause unrelated traffic, record the provider, and test across more than one date.
- Should I compare my test with advertised or typical speed?
- Keep the two references separate. Advertised speed describes the plan value used in marketing or sale, while a US Broadband Consumer Label separately discloses typical download, upload, and latency. The audit reports both without treating them as interchangeable.
- What percentage of advertised internet speed should I get?
- There is no universal percentage that proves compliance for every plan, technology, place, or test method. SwiftSpeedTest uses transparent descriptive bands at 90 and 100 percent to organize a browser sample; those bands are not contractual, legal, or regulatory thresholds.
- Why does the plan audit use a median?
- A median reduces the influence of one unusually high or low observation. It is still only a summary of the selected browser runs and cannot remove device, Wi-Fi, routing, endpoint, or time-of-day effects.
- Which speed test results are eligible for the audit?
- The aggregate includes locally measured runs with full download and upload transfer confidence. Editable shared results and runs with missing or degraded transfer confidence are disclosed and excluded.
- Can this report prove my ISP violated its contract?
- No. It is an organized browser evidence packet, not a certified access-line measurement, legal opinion, or regulatory finding. Keep the original plan label and bill, repeat controlled wired tests, and follow the provider or regulator process that applies in your location.
- Where are the plan details and test history stored?
- The plan form and recent speed-test history stay in local browser storage on the device running the test. They are not stored in a SwiftSpeedTest account. JSON and CSV downloads occur only when you request them.
