Track card's time in list in Trello
Jun 1, 2025
Timing metrics help you understand how long it takes to complete a task. Cycle time measures the elapsed time from the start of work on a card until it’s ready for delivery.
With Screenful, you can track timings for Trello cards with 15 different charts, and share that information with other stakeholders by scheduling automated reports.

How to measure card's time in list correctly?
Capturing the full cycle time of a Trello card can be done by observing the card transition history available via the Trello API. However, some pitfalls should be avoided. To get accurate timings, you should take into account the following aspects:
What if the card skips columns, or there is no sequential workflow?
What if a card is moved from the “not started” state directly to “done” without going through any of the “in progress” states?
How does the cycle time work if a card is moved into "in progress" and then back to "not started yet"?
What if a card is moved from "in progress" to "done", but then back to "in progress" again?
Should the out-of-office hours and weekends be included in the cycle time calculations?
Read on to learn how to visualise lead and cycle times of one or more Trello cards with various charts.
See timings for work in progress
To create a custom chart with Screenful, go to the Charts tab and click Add new chart in the top right corner. A modal is opened with a set of chart templates. You can either create a new chart from scratch or pick one of the predefined charts.
You can filter the template list using the top search box. Searching "timings" shows the charts related to the timing metrics. Click the first template called Timings for work in progress:
The resulting chart shows the current cards in progress and how long they've been in progress so far:
The Time in progress column shows how long ago that task was started. The summary at the bottom shows the average time in progress across all cards currently in progress.
You can configure the summary in the chart settings to display either sum, average, or median.
When you hover the mouse over the question mark, you see the movements between columns on your Trello board:
On the tooltip, you see all the movements between the columns in your board and how long the card stayed in each column. This view displays all the moves between states, including bounces backward in the pipeline.
The rightmost column shows the totals per column:
The Timings by workflow state column shows the total time the card has spent in different columns so far.
You can use the Task list chart to display the timings for any Trello card.
See the trend of your cycle time
The Cycle time trend shows your cycle time over the selected date range. You can filter the data according to a label or a custom field to track a specific aspect of your work, such as bugs, features, or support tickets. Timings are calculated from the completed cards.
Cycle time is a measure of the elapsed time from the start of work on an item (story, task, bug, etc.) until it is ready for delivery.
What can you do with that data? Let's consider a situation where your team is asked by business owners how long does it take to implement a certain functionality. Instead of just making a guess, the team can look at the data to see how long it has taken in the past to complete similar tasks and provide a data-driven estimate.
Another good way of visualising cycle times is by using a scatter plot, which presents data points in two dimensions according to the selected variables - cycle time and completion date.
Each circle corresponds to a completed card. The higher the circle, the longer it took to complete it. The horizontal axis is time. That allows you to visually see the outliers. For example, you can see how many cards took more than 7 days to complete.
See how long each workflow step takes
While it is helpful to know your overall cycle time and its trend, you may want to dig in deeper. The Cycle time per workflow state chart shows the average cycle time per workflow step (board column). The numbers represent the average time an issue has stayed in that specific list in the selected period.
This chart tells you which steps in your workflow are the quickest and which are the slowest. For example, if tasks spend a lot of time in waiting in some specific state, removing that delay would increase your throughput, and overall delivery speed.
You can also track the cycle time trend of any individual workflow state. Here's a line chart showing the trend for the In review state:
In this example, the review time has decreased by 38,5% during the selected time period, which is a positive trend. If the trend shifts and the review step starts to slow down, you might consider adding more QA resources or exploring alternative ways to reduce delays in that specific step.
Set working hours
When you create a chart using the Time in state unit, there is a checkbox only working hours. When selected, the chart will calculate the timing metrics from the working hours only.
The working hours can be specified in the Account settings:
You can select the working days (e.g. Monday to Friday) and the working hours (e.g. 08 to 16)
You can also choose to only include working days on the Burndown chart by checking Exclude non-working days in the chart editor. When doing so, the ideal burndown is flat during the non-working time (e.g. weekends).
Create a cycle time report from a template
The quickest way to get the cycle time metrics is by using a report template. Go to the Reports tab and click Add new report:
A modal opens, showing the available templates. Select Timings report. You'll get a complete report containing the metrics introduced in this article.
The best thing is that each chart in the report is configurable so you can create the exact report you need.
