Sprint Capacity & Delivery Confidence Calculator

Turn capacity, focus factor, and interrupt load into a confidence band for the sprint.

Honest delivery confidence from hours, meetings, and interrupts — not story-point theater.

How it works

Enter team size, sprint length, hours/day, meeting load, focus factor, and interrupt load.

Sprint inputs

Honest inputs beat optimistic calendars. Defaults are a starting point.

Team size (people) Contributors with capacity this sprint (exclude long leave).

Sprint days Working days in the sprint (exclude holidays).

Hours / day Paid hours available before meetings and interrupts.

Meeting load (%) Share of gross hours in ceremonies, syncs, and reviews.

20%

Focus factor Share of remaining time that is deep work (0.60–0.85 typical).

0.75

Interrupt load (%) Production support, unplanned asks, context switches.

15%

Committed story points What the team plans to pull into this sprint. Historical velocity (points / sprint) Average completed points over recent sprints.

Capacity & confidence

Defaults match the form. Change any input — numbers refresh instantly.

Available capacity — Hours after meetings, interrupts, focus

Capacity vs commitment — Velocity-normalized load vs capacity band

Confidence band — High / Medium / Low

Cut-line suggestion — Scope to drop for a safer sprint

How the model works

Gross hours = team size × sprint days × hours/day.
After meetings = gross × (1 − meeting %).
After interrupts = after meetings × (1 − interrupt %).
Available capacity = after interrupts × focus factor.
Commitment load compares committed points to historical velocity and maps load onto capacity (points-per-hour implied by velocity ÷ typical capacity).
Confidence: High when commitment ≤ ~90% of velocity and capacity is comfortable; Medium when tight; Low when overcommitted — suggest a cut-line.

All math runs in your browser. Prefer cutting scope early over heroic overtime.

FAQ

How is available capacity calculated?

Gross hours = team size × sprint days × hours/day. Then subtract meeting load and interrupt load, and apply focus factor. Result is available capacity hours for committed work.

What is focus factor?

Focus factor is the share of remaining time that is truly deep work (typically 0.6–0.85). Lower focus means less delivery capacity even if calendars look open.

How is delivery confidence decided?

We compare committed points to historical velocity and to capacity vs commitment %. High ≈ comfortably under capacity and near velocity; Medium ≈ tight; Low ≈ overcommitted — cut scope.

What is the cut-line suggestion?

When commitment exceeds a safe band of historical velocity (or capacity is thin), the calculator suggests how many points to cut so the sprint lands in a Medium/High confidence band.

Should I use points or hours?

Capacity is hour-based; commitment uses your team’s story points and velocity. Keep both honest — padding points while ignoring interrupts creates false confidence.

Are results a guarantee of delivery?

No. This is directional planning. Dependencies, production incidents, and scope creep still move outcomes. Use it for sprint planning honesty, not as a performance scorecard.
