How It Works

How to Calculate Study Efficiency

Study efficiency measures what percentage of material you have mastered relative to what you need to learn.

Formula

Efficiency = (Topics Mastered / Total Topics) x 100

Topics per Hour = Topics Mastered / Hours Studied

Tracking efficiency helps you identify which study methods produce the best results per hour invested.

Worked Example

A student has mastered 12 out of 20 topics in 6 hours of study.

topics_mastered = 12total_topics = 20hours_studied = 6
  1. 01Study efficiency = (12 / 20) x 100 = 60%
  2. 02Topics per hour = 12 / 6 = 2.0
  3. 03Remaining topics = 20 - 12 = 8
  4. 04Estimated hours remaining = 8 / 2.0 = 4.0 hours
