About Study Hours Planner
Builds total study time from a first pass at full length plus subsequent revision passes at roughly half the time each, since re-covering known material is faster. Available hours are discounted by an efficiency factor because scheduled study time is never fully productive.
Formulas
Total hours
Total = topics x hours per topic x (1 + 0.5 x (passes - 1))
Weekly requirement
Per week = total hours / (weeks x efficiency)

Assumptions and limits
- The result is derived only from the 6 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
Why discount available hours?
Because two hours blocked out rarely yields two hours of learning. Setup, distraction and fatigue mean 70-80% is a realistic figure for most people.
Are later passes really half the time?
Roughly, for well-spaced retrieval practice. If the first pass was passive reading rather than active recall, later passes take nearly as long.
