About this calculator
The Agile Burndown Calculator helps development teams estimate the remaining time to complete a project or sprint. Based on the total remaining points (stories or tasks) and the team's daily velocity (points delivered per day), the tool calculates how many working days are still needed. This allows objective progress tracking and facilitates planning adjustments.
It works simply: enter the remaining points and daily velocity. The formula is days remaining = remaining points / daily velocity. For example, if 40 points remain and the team delivers 5 points per day, 8 days are needed. The result is rounded up, as fractional days are not worked. The tool does not consider holidays or days off, only consecutive working days.
Use this calculator at the start of a sprint to predict the delivery date, or during the sprint to check if the pace is adequate. It is also useful for larger projects divided into sprints, allowing replanning if velocity changes. Scrum masters and product owners can use it to communicate deadlines transparently with stakeholders.
Caveats: daily velocity should be based on reliable historical data, not optimistic estimates. Remember that unforeseen events (meetings, bugs, dependencies) can reduce actual velocity. The calculation assumes a constant pace, which may not hold. Always reassess velocity each sprint to keep the forecast accurate.
Frequently asked questions
What is daily velocity in an agile project?
It is the average number of story points or tasks the team can deliver in a working day, calculated from previous sprints.
How do I round the result of remaining days?
The calculator rounds up, since you don't work half a day. For example, 3.2 days becomes 4 days.
Can I use this calculator for 1-week sprints?
Yes, as long as the daily velocity is consistent with the team's capacity. Adjust velocity if the sprint has holidays.
What if velocity changes during the sprint?
Recalculate with the new velocity. The tool is useful for simulations and continuous replanning.
Does the calculator consider weekends?
No, it only considers consecutive working days. If there are breaks, you should manually adjust velocity or use a weekly average divided by 5.
