Estimate Available Team Capacity for a Planning Period

Use this calculator

Estimate team hours available for planned project work after absence and an explicit project allocation. Use the result to discuss capacity, not to promise delivery.

Formula and units

Gross hours = people × working days × hours per person per day. Remaining hours = gross hours − total team absence hours. Project capacity = remaining hours × allocation ÷ 100.

Worked example

5 people × 10 days × 7.5 hours = 375 gross hours. Subtract 15 team absence hours, then allocate 80%: 288 project hours.

Inputs and limits

• People in the team: 1 to 10000 (whole numbers only).
• Working days in the period: 0 to 366 (whole numbers only).
• Working hours per person per day: 0 to 24.
• Total team absence hours in the period: 0 to 100000000.
• Project allocation of remaining time (%): 0 to 100.

The upper bounds are practical input limits for this tool, not professional standards. Enter decimal numbers using a point, without currency symbols, commas or scientific notation.

Assumptions and interpretation

Use the same daily-hours assumption for everyone. Enter team absence as a combined total, not a per-person figure. Count working days only. Use allocation to allow for non-project commitments, such as routine support. Do not count the same absence twice. People have different skills and availability; capacity is not an estimate of task effort or a delivery commitment.

Rounding and data handling

Calculations use the entered values before rounding. Results display to two decimal places. A tiny non-zero result may display as 0.00; review the input units and magnitude. Financial figures are indicative, not accounting entries. Inputs are processed in browser memory only: this calculator does not submit or store them, and reset or reload clears them. Ordinary website page requests still occur. Do not enter personal or confidential information. Without JavaScript, use the formula and worked example above manually.
