Calculator Inputs
Formula Used
Base Effort = (Pages × Minutes per Page) + (Questions × Minutes per Question) + Research Minutes + Writing Minutes + Review Minutes
Difficulty Adjusted Effort = Base Effort × Difficulty Multiplier
Focus Adjusted Effort = Difficulty Adjusted Effort ÷ (Focus Efficiency ÷ 100)
Break Time = (Focus Adjusted Effort ÷ 60) × Break Minutes per Hour
Buffer Time = (Focus Adjusted Effort + Break Time) × Buffer Percent
Total Estimated Duration = Focus Adjusted Effort + Break Time + Buffer Time

FAQs
1. What does this calculator estimate?
It estimates realistic homework time by combining reading, questions, research, writing, review, focus efficiency, breaks, and extra safety buffer.
2. Why use a difficulty multiplier?
Different subjects demand different effort. The multiplier raises or lowers the base workload so hard topics receive more realistic study time.
3. How should I choose focus efficiency?
Use 90 to 100 for highly focused sessions, around 75 to 85 for normal study, and lower values when distractions often slow progress.
4. What is buffer time for?
Buffer time protects your plan against confusion, rework, missing notes, slow internet, unexpected interruptions, or extra revision before submission.
5. Can I use this for group projects?
Yes. Add shared reading, research, writing, and review time. Then divide the final estimate across team members if responsibilities are evenly split.
6. Why does the total exceed base effort?
The total includes difficulty adjustment, real focus limitations, planned breaks, and a buffer. Base effort only measures the raw task workload.
7. Is the daily target mandatory?
No. It is a planning guide. You can change target days or sessions per day until the schedule fits your routine and energy level.
8. Does this replace a study timetable?
No. It complements a timetable by showing time demand first, helping you build a schedule with more accurate study blocks.
