How to Use the Book vs Video Learning Efficiency Calculator
When learning the same topic, it's often unclear whether a book or a video will get you there faster. This calculator takes the time you spent on each method and your self-rated comprehension afterward, then computes learning efficiency per hour so you can compare them with real numbers instead of a gut feeling.
Efficiency is comprehension (%) divided by time spent (hours). Shorter time at the same comprehension, or higher comprehension at the same time, both produce a higher efficiency score. Treat the result as a reference — actual results vary with focus level and repetition.
Don't stop at one measurement — try it across a few topics to learn which medium tends to work better for you personally. It's common to find videos more efficient for grasping concepts, while books work better for detailed memorization.
Frequently Asked Questions
Rate how much you feel you understood after studying, on a 0-100% scale. A rough subjective estimate is fine — you don't need a formal test score.
If the gap is small, choose based on cost or which medium keeps you focused. Combining both — video for concepts, books for review — often works well too.
