This tool helps you estimate completion dates and timeline requirements for your projects based on your daily work capacity and total task volume.
Estimated Completion Date:
1970-01-06
Total Calendar Days:
5 days
Based on a start date of , working 8 hours daily to complete 40 total hours.
Interpretation: This date assumes a continuous work schedule without weekends or holidays. If your team only works business days, please adjust the calendar days accordingly.
Project duration is the measure of time from the start to the end of a project. To calculate it manually, you determine the total effort required in hours and divide it by your team's daily capacity or availability.
Completion = Start Date + (Total Hours / Daily Hours)
To illustrate how this works, let's look at a typical software development sprint or small project estimated at 120 total work hours.
Standard duration formulas calculate 'working days'. To find the actual calendar completion date, you must skip over Saturdays, Sundays, and any regional public holidays.
If you work part-time or have varying availability (e.g., 4 hours on Friday), it is best to use an average 'hours per day' figure for a rough estimate, or map specific hours to a project calendar for precision.
Experienced project managers always include a 'buffer' or 'contingency' time. Adding 20% to your total hours estimation is a common strategy to protect against unforeseen technical challenges or scope changes.
