What is Habit Success Predictor?
Most habits fail not because the idea is bad, but because the plan is too demanding for real life. A habit that looks easy on paper can be hard to sustain when time, energy, and motivation fluctuate.
Habit Success Predictor estimates the chance of sticking with a habit based on difficulty, time required, motivation, and past consistency. It helps you choose a realistic version of the habit before you commit.
Use it as a planning aid. The best results come from adjusting inputs and seeing how small changes improve the probability.
Habits break when effort and consistency are mismatched
People often choose ambitious habits without accounting for daily time costs.
Motivation is treated as a fixed trait even though it changes with stress, sleep, and workload.
Past consistency is a strong predictor, but many plans ignore it.
Without a simple check, it is easy to overcommit and abandon the habit early.
A probability score that encourages realistic planning
Enter difficulty, daily time, motivation, and past consistency to get a success probability.
Use the score to test a lighter version of the habit, such as fewer minutes or fewer days per week.
Limitations: the model is simplified and does not capture social support, environment, or health constraints.

Frequently Asked Questions
What is past consistency?
Your recent completion rate, such as how many days you met the habit last week.
Can I use this for weekly habits?
Yes. Convert the time per week into a per-day average.
Is a low probability a bad sign?
It is a signal to reduce difficulty or time, not to quit.
How should I rate motivation?
Use your honest current level, not your ideal future level.
Does the tool account for reminders?
No. It focuses on difficulty, time, motivation, and consistency.
Can I compare multiple habit ideas?
Yes. Try different inputs to see which is most realistic.
What if I have no past data?
Use an estimate based on similar habits or start with a low consistency value.
Should I aim for 100 percent?
Not necessarily. A high but realistic probability is better than a perfect target.
Does it store my habit data?
No. Everything stays in your browser.
Can I use this with a coach?
Yes. Share the inputs and assumptions for alignment.
Is this a psychology test?
No. It is a planning aid, not a diagnosis tool.
