How these calculators are built

Grounded in the Scrum Guide, honest about team choices, and built for teams that work with AI.

Scrum Guide firstWhere the Scrum Guide says something, the tools follow it. Where it doesn't, the default is shown and you can change it.
Agents are not membersAI agents add capacity to the work, but accountability stays with people. The tools count the human time needed to verify agent output.
Private by designAll calculations run in your browser. Nothing you enter is sent to our servers.

Frequently asked questions

Are the calculators free?

Yes. Every calculator is free to use with no sign-up.

Is the data I enter stored anywhere?

No. Calculations run in your browser. Some tools offer an option to remember your inputs on your own device, and you can clear it at any time.

Who reviews the calculators?

Each tool is reviewed by Sanjay Saini, a Professional Scrum Trainer licensed by Scrum.org, before it goes live.

Which calculator should I start with?

Start with the Sprint Capacity Calculator before your next Sprint Planning. It shows how much time the team really has once holidays, leave, events and AI review are taken out. If your team works with AI agents, paste your candidate stories into the User Story Token Estimator during refinement, then check the whole Sprint with the Sprint Token Budget Calculator.
