The Weekly Deadline Planner estimates whether a defined amount of work can be completed before a near-term deadline. Enter the work remaining, productive days left, usable hours per day, and a buffer percentage. The calculator converts the buffer into protected capacity, reports effective available hours, and shows the daily pace required to finish on time.
This is useful for assignments, reports, deliverables, and other work that can be estimated in hours. A capacity surplus indicates room for uncertainty, while a deficit shows the additional hours that must be found or the scope that must change. The model assumes work can be distributed across the remaining productive days; dependencies, review cycles, and fixed sequencing may make the practical schedule tighter than the numerical result.

1. Estimate work remaining Use active work hours, not elapsed calendar time.
2. Count productive days Exclude days that cannot realistically contribute to the deadline.
3. Set daily usable capacity Enter hours available after meetings and other fixed commitments.
4. Choose a buffer Reserve a percentage for uncertainty, revisions, and interruptions.
5. Review pace and margin Compare required daily hours with the capacity you can sustain.
Gross capacity = Productive days × Usable hours per day
Effective capacity = Gross capacity × (1 − Buffer % ÷ 100)
Capacity margin = Effective capacity − Work remaining
Required daily pace = Work remaining ÷ Productive days
What the result means
A positive result is buffered capacity beyond estimated work; a negative result is the shortfall.
The planner assumes the work estimate and daily capacity use the same definition of productive hours.
Given: 24 hours of work, 5 productive days, 6 usable hours per day, and a 15% buffer.
