These are the actual published outputs of the widget with sample sizes and speeds. Change a number or a unit to see the estimate update.

Transfer duration estimator controls in Elementor
Calculation sets decimal or binary size units, the starting size and speed with their units, an allowance for overhead and the speeds to compare. Behaviour switches live calculation, the bytes-per-second line and the Clear button. Labels holds every text. The Style tab covers the fields and unit lists, the result box and comparison table, labels and messages, the widget and the buttons.
03 / Website use cases
Where to use transfer duration estimator
Software, game, course and media sites publish file sizes in GB while visitors know their connection in Mbps, and the factor of eight between bytes and bits trips almost everyone up. Transfer duration estimator sits on your own page: visitors type the size and their speed, each with a unit, and see a readable time such as 13 min 56 s, the speed read as bytes per second, an optional allowance for overhead and a table of times at other speeds. Nothing is sent anywhere.
Course and media libraries
Help learners plan video or audio downloads before a trip.
Backups and hosting
Estimate how long an upload of a site or photo library takes at a given upload speed.
04 / Installation and setup
How to add a download time calculator in Elementor
Start with Complementor installed and your license connected. Enable this module in the WordPress library, then configure it in Elementor.
Install Complementor, connect your license and enable Transfer duration estimator in the Complementor library.
Add the widget to a page, for example next to a download button or a file list.
Under Calculation, choose decimal or binary units and optionally set a starting size and speed with their units.
Optionally add an allowance for overhead and speeds to compare, then adjust the texts under Labels and Behaviour.
Style the fields, result and buttons under Style, then change a number to check the estimate.
05 / Content and style controls
Customize transfer duration estimator in Elementor
Configure the settings available for this module to suit the page you are building.
Size in bytes, kB, MB, GB or TB, in decimal (1 GB = 1,000 MB) or binary (1 GiB = 1,024 MiB) units.
Speed in kbps, Mbps, Gbps or MB/s, with a line reading it the other way, such as 100 Mbps = 12.5 MB/s.
Readable times from under 0.1 s to days, such as 2 min 40 s or 4 h 27 min.
Allowance for overhead from 0 to 90%, with the full-speed time shown beside the estimate.
Optional table of times at up to 8 speeds you list, such as 10, 100 and 1,000 Mbps.
Results as visitors type or with a Calculate button and optional icon; Style sections for fields, result, table, labels and buttons.
06 / Choose the right approach
Transfer duration estimator and Elementor alternatives
Compare the existing Elementor workflow with this Complementor module before choosing your setup.
A file size next to the download button
Enough when visitors only need the size; it leaves the bits-and-bytes conversion and the time to them.
Elementor's Progress Bar or Counter widgets
Show numbers you set; they do not calculate a time from what visitors enter.
An online speed test or calculator site
Measures or converts elsewhere and takes visitors away from your page.
07 / Requirements and compatibility
Transfer duration estimator compatibility with Elementor
- Requires Elementor; works without WooCommerce.
- An estimate from the size and speed entered; it does not measure the connection.
- Sizes and speeds up to 1,000,000,000,000 in the chosen unit.
Complementor uses classic Elementor APIs. Atomic-native controls are not implemented. Check your theme, cache and integrations on a staging site before release.
08 / Common setup problems
Troubleshoot transfer duration estimator
Check these settings if the published page behaves differently from the editor.
Why is the time eight times longer than size divided by speed?
File sizes are in bytes and internet speeds in bits, and a byte has 8 bits. The detail line shows the speed in bytes per second, such as 100 Mbps = 12.5 MB/s.
Why does Windows show a different size for the same file?
Windows counts 1 GB as 1,024 MB (binary units). Choose binary units under Calculation to match it; they are labelled GiB and MiB.
Why is a real download slower than the estimate?
Protocol overhead, Wi-Fi and busy servers lower the speed. Set an allowance for overhead, for example 10, to assume 90% of the line speed.
Why does 1,000 show a message?
A comma followed by three digits is read as a thousands separator, which is not accepted so it cannot be mistaken for a decimal comma. Type 1000, or 1 000 with a space.
Transfer duration estimator plugin questions
Does it need Elementor Pro?
No. It works with the free version of Elementor.
Does it measure the visitor's real connection?
No. Visitors type their speed, for example from their plan or a speed test; the widget makes no network test.
Can visitors use decimals?
Yes, with a point or a comma, such as 1.5 or 1,5.
Can I show several speeds at once?
Yes. List up to 8 speeds under Calculation and a table shows the time at each.
Does it need JavaScript?
Yes. Without it a short message is shown instead.
