Team Capacity Calculator

How to use this calculator

Choose the planning dates and team closures. Add uniquely named people with their available daily hours and workweek. Match absence names exactly to those people.

Available hours should already exclude meetings and other commitments. Absence entries describe total unavailable hours on a date. Repeated entries for a person and date use the maximum, preventing duplicate deductions; combine separate absences into one total. Leave is capped at scheduled capacity.

A worked example

Over two weeks, Alex has ten six-hour days and Sam has eight four-hour days. Removing one six-hour absence from Alex leaves 86 person-hours.

Why use person-hours rather than elapsed hours?

Two people working six hours together provide 12 person-hours in six elapsed hours. Team capacity sums individual availability; it does not predict a project finish date or task dependencies.

Which calendar and years are supported?

Use Gregorian dates from 1900 through 2100, with results inside that range. Most daily plans are limited to 366 dates; academic terms and sprint plans allow up to 731. Forms limit the number of entries to keep calculations responsive. Holidays and policy rules come from your inputs. Date-only plans ignore DST; tools with time-zone inputs use the browser's time-zone data and explicitly resolve repeated times. Calendar exports preserve date-only markers or exact timed events as appropriate. Calculations run only when requested, without background polling.

What happens to my dates?

Calculations run on your device. Saving a calculation is optional and keeps it in this browser. A setup link contains the dates and settings you entered; anyone with the link can read them. Use one tab per saved calculator. Clear saved data from Privacy & settings.
