Free agile tools
Calculators and generators for the parts of scrum that involve arithmetic nobody enjoys doing twice. Every tool shows its working — the formula, a worked example, and where the number stops being trustworthy.

Calculators
The arithmetic of planning, estimation and facilitation. The line on each card is that calculator’s worked example — real inputs, and the answer it actually gives.
Sprint velocity calculator
Enter completed points from your last few sprints and get the average, the spread, and a commit / expect / stretch range — not one misleading number.
14 · 26 · 19 · 31 · 17 · 24 → commit 16 · expect 22 · stretch 28
Open calculatorSprint capacity calculator
Nets out leave, ceremonies and focus factor per person, so you plan against the hours that actually reach the backlog. For the sprints that don’t look like the last few.
5 people × 2 weeks = 400 h headline → 211 h that reach the backlog
Open calculatorStory points to hours
Derives hours per point from your own sprint history rather than an invented constant, and answers with a range — because the honest conversion has error bars.
13 points × 4.2–9.5 h/point = 55 to 124 hours
Open calculatorRetrospective timebox calculator
Sprint length and team size in, a minute-by-minute five-phase agenda out — ready to paste straight into the calendar invite.
2-week sprint, 7 people → 90 min · 5 phases · 7 min airtime each
Open calculatorGenerators
For the parts of the sprint that are meant to be fun.
Sprint name generator
Memorable sprint names across 16 themes, with formats, alliteration, and a series mode that names a whole quarter in one go.
Sprint “Wobbly Traffic Cone” · Sprint “Ancient Kraken” · Sprint “Sleepless Capybara”
Open the generatorWhy these tools show their working
Most agile calculators on the web give you a number and no way to argue with it. That is a problem, because every one of these numbers is an estimate resting on assumptions your team may not share — a focus factor someone guessed, a velocity averaged over a team that has since changed shape, a points-to-hours ratio that was never stable in the first place. Each tool here shows the formula, walks through a worked example with real numbers, and says plainly where the result stops being trustworthy.
The pattern worth internalising across all of them: a single number is almost always the wrong output. Velocity is a range, capacity is a ceiling rather than a target, and a points-to-hours conversion is mostly useful for showing you how wide the uncertainty really is. The retrospective is where a team decides what to do about what those numbers revealed.
Frequently asked questions
Are these agile tools really free?+
Yes — every calculator and generator here runs entirely in your browser, needs no account, and has no usage limits. Nothing you type is sent to a server, which is also why you can use them with real team data.
Which calculator should you use for sprint planning?+
Start with the sprint velocity calculator: for a normal sprint, what your team has historically delivered is the best predictor of what it will deliver. Switch to the sprint capacity calculator when the coming sprint is unusual — a holiday week, someone onboarding, or a planned rotation — because the historical average is misleading in exactly those sprints.
Can you share a calculator result with your team?+
Yes. The calculators keep your inputs in the page URL, so copying the address bar shares the exact result you are looking at. Every tool also has a copy button that produces a plain-text summary you can paste into a ticket, a document, or a chat message.
The numbers say what happened. The retro decides what changes.
FocusRetro gives the same team a calm board for honest feedback, blind voting, and action items that survive until next sprint.
