How capacity is calculated

A reference page for the capacity formula — what every number on the Sprint Capacity Summary means, where it comes from, and how it is combined.

Anyone trying to understand or reconcile capacity numbers.

Ekko's capacity summary is intentionally explicit — every number is labelled and traceable. This page is the formal definition: what each row means, where its value comes from, and how the final "available" and "workload %" are calculated.

Capacity respects your capacity mode setting — every value below is in hours OR in story points, never mixed.

The headline formula

Every term on the right-hand side is shown on the per-person card so you can audit it without leaving the page.

Inputs (where the numbers come from)

Sprint date range
From the Jira sprint object. If a sprint has no dates, Ekko falls back to next Mon → +13 days so you still see capacity.
Business days
Org setting (Settings → Business Days). Number of working days in the sprint = business days inside [start, end].
Working hours/day or points/day
User setting from Settings (overridden per-person in Team Management if set).
Holidays
Any holiday from the org-wide Holidays list whose date falls inside the sprint.
Time off (PTO)
Per-person entries that overlap the sprint, scaled by their units-per-day.
Tax
User setting OR per-person override, multiplied by the number of weeks in the sprint.
Assigned
Sum of original estimate (or remaining estimate, or story points — your choice) across this person's issues in the sprint.

A worked example

Consider a 2-week sprint (10 business days), team default 6 hours/day, default tax 3 hours/week. One person, "Sam":

Total possible
10 days × 6 h = 60 h
Holiday
1 holiday in the sprint, scaled by 6 h = 6 h
Time off
Sam took 2 full days off and 1 half day → (2 + 0.5) × 6 h = 15 h
Tax
3 h/week × 2 weeks = 6 h
Available
60 − 6 − 15 − 6 = 33 h
Assigned
Sam has 4 issues, original estimates 8h + 8h + 6h + 4h = 26 h
Workload %
26 ÷ 33 = 79% — green

Sort order and colour coding

  • The capacity summary sorts by workload % desc — over-committed people surface first.
  • Workload chip is green at 0–100%, amber 100–120%, red 120%+.
  • A person with available = 0 (entirely on PTO + tax) shows as "Out" rather than a divide-by-zero.
