Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- No break after the last block. This is a schedule calculation, not a claim about an optimal attention span.
Example Calculation
- Work blocks: 8
- Work block duration: 25 min
- Short break: 5 min
- Blocks per long-break cycle: 4
- Long break: 15 min
Eight 25-minute blocks, six 5-minute breaks and one 15-minute break take 245 minutes.
Frequently asked questions
How do I use this calculator?
Enter work blocks, work block duration, short break, blocks per long-break cycle, long break. The result updates automatically. Use Reset to restore the example values.
What method does it use?
breaks occur only between work blocks; every cycle-th intervening break is long.. No break after the last block. This is a schedule calculation, not a claim about an optimal attention span.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
