Features & Capabilities

Sprint Capacity Calculator is a tiny, lightweight extension that helps Scrum Masters and engineering teams plan the next sprint without spreadsheet gymnastics.

Enter your sprint working days, team size, average story-point velocity, and total days off across the team (PTO, NPDDs, etc.). Capacity updates live as you type.

How it works • Points per person per day = average velocity ÷ working days ÷ contributors • Capacity = velocity − (points per person per day × total days off) • Reduce working days when holidays fall in the sprint

Features • Live calculation — no Calculate click needed • Persistent inputs via Chrome storage (stays on your machine) • Dedicated window that stays open while you plan in Jira or Docs • Lightweight Manifest V3 extension — storage permission only; no account, no tracking, no network access

Built for sprint planning rituals where you need a clear “how many points can we pull?” number in seconds.

Is Sprint Capacity Calculator Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Sprint Capacity Calculator does not require any sensitive permissions.

Risk impact analysis details

Low This permission has no access or impact on the user's system or data, thus carrying no risk.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Sprint Capacity Calculator is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
