Education Calculators

Students consistently underestimate how much study time a target grade actually requires, and overestimate how much they can absorb in a single session. These calculators apply cognitive science research on spaced repetition, reading speed, and memory retention to give you a realistic study plan. The GPA calculator handles both weighted and unweighted scales across US grading systems. The tuition ROI calculator compares the cost of a degree against lifetime salary uplift by major — using BLS Occupational Outlook data — to help prospective students make one of the most significant financial decisions of their lives with actual numbers.
