Deadline Back Planner

Back-plan start date and milestones from a fixed deadline, workload, and daily capacity.

Input values

Results update as you use the interface above.

Enter the deadline, total work required, and daily capacity to back-calculate the required start date and intermediate milestones.

Enter the deadline date and time
Set the fixed deadline: the non-negotiable end point. This anchors the entire back-calculation.
Enter total work hours and daily focus capacity
Enter how many hours the project requires in total, and how many focused hours you can realistically work per day. Be conservative: most people overestimate this.
Set the buffer percentage and weekend policy
Add a buffer (e.g. 20%) to absorb scope creep, reviews, and blockers. Choose whether weekends count as working days. The buffer is applied before distributing work across days.
Review the required start date and milestones
The result shows the required start date and evenly spaced milestone checkpoints. If the start date is in the past, the plan is already overrun: adjust scope, capacity, or deadline.
