Study Time Calculator
Study Time Calculator: free, instant and private. Two 90-minute sessions across the day beat one 3-hour block — sleep between sessions is when consolidation happens.
How the Study Time Calculator works
The Study Time Calculator takes Topics to cover (one per line), Days available, Study hours per day and returns the answer instantly — no button to hunt for, no page reload. Two 90-minute sessions across the day beat one 3-hour block — sleep between sessions is when consolidation happens. Leave the last 10–15% of days as revision buffer; plans without buffer fail at the first disruption.
Enter your own numbers to replace the example values; the result panel updates as you type. Everything runs in this single page, so nothing you enter leaves your device.
Formula used
minutes per topic = total study minutes ÷ topics, split into two sessions per day
| Symbol | Meaning |
|---|---|
| two sessions | morning and evening — spacing beats one marathon block |
| per-topic minutes | equal split; star your weak topics for a second pass |
| total hours | days × hours per day |
Two 90-minute sessions across the day beat one 3-hour block — sleep between sessions is when consolidation happens. Leave the last 10–15% of days as revision buffer; plans without buffer fail at the first disruption.

Worked example
Take the default example — topics to cover (one per line) of Thermodynamics Optics Electromagnetism Modern Physics, days available of 30, study hours per day of 3:
- list: Day 1 (session 1): Thermodynamics — ~1350 min, Day 1 (session 2): Optics — ~1350 min, Day 2 (session 1): Electromagnetism — ~1350 min, Day 2 (session 2): Modern Physics — ~1350 min
- perTopicMinutes: 1,350
- totalHours: 90
