Free Study Hours Planner calculator with clear step-by-step results.
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.
Total hours
Total = topics x hours per topic x (1 + 0.5 x (passes - 1))
Weekly requirement
Per week = total hours / (weeks x efficiency)
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.
Roughly, for well-spaced retrieval practice. If the first pass was passive reading rather than active recall, later passes take nearly as long.
