How to use this calculator
- Enter estimated hours required and realistic available capacity.
- Add task counts and high-priority task volume.
- Rate stress and deadline pressure.
- Include a contingency buffer and the number of weeks available.
Compare required work with your realistic available capacity. This calculator measures workload utilization, overload probability, weekly completion gap, stress pressure, and the amount of work that should be deferred or rescheduled.
Workload utilization compares buffered required hours with total capacity. Capacity gap shows excess or spare hours, and overload probability incorporates utilization, stress, deadline pressure, and task concentration.
Available capacity should represent effective work time, not simply scheduled hours. Use the Solo Capacity Calculator first when capacity is uncertain.
If 45 hours of work must fit into 40 hours of capacity with a 10% contingency buffer, buffered workload becomes 49.5 hours and utilization exceeds 120%.
A workload above realistic effective capacity is overloaded. Even 90%–100% utilization can be risky when tasks are uncertain or deadlines are rigid.
Compare buffered required hours with effective weekly capacity, then review stress, deadline pressure, and the share of tasks that are high priority.
A practical target is often around 75%–90% of effective capacity, leaving room for revisions, communication, and unexpected work.
Cut low-impact scope, sequence dependencies, renegotiate deadlines, batch similar work, and defer tasks that do not affect the current objective.
Estimate each project’s hours and deadline risk, reserve fixed capacity by priority, and avoid treating every project as equally urgent.
| Utilization | Workload status |
|---|---|
| Below 75% | Light with strong contingency |
| 75%–95% | Healthy to moderately tight |
| 95%–110% | Heavy and vulnerable to delay |
| Above 110% | Critical overload requiring scope or deadline change |
