Pomodoro Task Estimator
Break your project into subtasks, rate the complexity of each, and get a realistic Pomodoro estimate with a day-by-day schedule.

Complexity Guide
Quick - 1 Pomodoro
Simple, well-defined tasks. Replying to emails, quick code fixes, short reviews. You know exactly what to do and how to do it.
Moderate - 2 to 3 Pomodoros
Tasks that need some thought. Writing a report section, designing a component, researching a topic. Clear goal but requires concentration.
Complex - 4 to 5 Pomodoros
Multi-step tasks with unknowns. Building a feature, writing a long document, solving a tricky bug. You might hit roadblocks and need to problem-solve.
Deep Work - 6 to 8 Pomodoros
Large, demanding tasks that require sustained deep focus. Architecture decisions, long-form writing, complex analysis. Often best spread across multiple days.
Why Estimate Before You Start
Most projects go over deadline for one reason: nobody thought about how long the work would actually take. We jump into tasks with a vague sense that it will take "a few hours" or "a couple days," and then reality hits. The task is bigger than expected, there are dependencies you did not see, and suddenly a two-day project becomes a two-week project.
Breaking work into subtasks forces you to think through the real scope. When you have to list every piece of the project and rate its complexity, hidden work becomes visible. That "simple redesign" suddenly has 15 subtasks across research, design, development, and testing. And that is useful information - not because it makes the project smaller, but because it gives you a realistic picture of what you are committing to.
The Pomodoro Technique gives you a natural unit for estimation. Instead of guessing hours (which humans are terrible at), you think in 25-minute focus blocks. A Pomodoro is concrete - you know what one feels like. Estimating in Pomodoros tends to be more accurate than estimating in hours because the unit is small enough that errors do not compound as badly.
How to Use This Estimator
Name your project at the top so you remember what this estimate is for. Then start breaking it into subtasks. Be specific - "write blog post" is one subtask, but "research topic, outline post, write draft, edit and polish, add images" is five subtasks, and each has a different complexity level. The more specific you are, the more accurate your estimate will be.
For each subtask, choose a complexity level. If you are not sure, go with one level higher than your gut tells you. People consistently underestimate task complexity, and building in a small buffer is better than running behind. The Pomodoro Calculator can help with specific calculations if you need them.
Once your subtasks are in, the estimator shows a day-by-day schedule based on your daily capacity. Adjust the capacity slider to match how many Pomodoros you can realistically do per day. If you have meetings and other commitments, you might only have 4 to 6 Pomodoros of focus time. On a clear day, you might hit 10 or 12.
Use the schedule to set realistic deadlines and plan your week. Move the subtasks to your Daily Planner when you are ready to start working, and use the timer to track your sessions.
Frequently Asked Questions
How does the task estimator calculate Pomodoro estimates?
The estimator uses your complexity rating for each subtask to generate a Pomodoro count. Quick tasks get 1 Pomodoro (25 minutes), moderate tasks get 2 to 3, complex tasks get 4 to 5, and deep work tasks get 6 to 8. These ranges are based on common project management heuristics for focused work sessions.
How many Pomodoros can I realistically do in one day?
Most people can complete 8 to 12 Pomodoros per day, which works out to 3.5 to 5 hours of focused work. The estimator defaults to 8 per day, but you can adjust this based on your schedule and experience. If you are new to the technique, start with 6 and increase as you build stamina.
Can I save my project estimate?
Yes. Your project and subtasks are saved in your browser's local storage automatically as you work. You can close the page and come back later to find everything where you left it. Nothing is sent to a server. Clearing your browser data will erase saved projects.
What if my estimate turns out to be wrong?
That is expected and useful. The estimator gives you a starting point, but real work always has surprises. After completing a few tasks, come back and adjust your complexity ratings. Over time your estimates will get closer to reality. The gap between your estimate and actual time is where you learn the most about your own work pace.
