Study Time Calculator

Make the most of your study time. Allocate your available hours across subjects based on how difficult each is.

Study Time Calculator

Add subjects with a difficulty (1–5).

How to use it

Enter your total available study hours, then add subjects with a difficulty rating (1–5). Hours are allocated proportionally — harder subjects get more time.

Formula

Subject hours = Total hours × Difficulty ÷ Σ(all difficulties)

Examples

Example: 20 hours across Math (5) and History (3). Math gets 20 × 5 ÷ 8 = 12.5 hr; History gets 7.5 hr.

Example: 10 hours across three subjects rated 2, 3, and 5. Split: 2 hr, 3 hr, 5 hr.

Frequently asked questions

How should I rate difficulty?
Use your own judgment: 1 = easy/familiar, 5 = very challenging or new material.
Should harder subjects always get more time?
Generally yes, but also weigh how much each subject counts toward your grade.
Can I add more than two subjects?
Yes — use '+ Add subject' to include as many as you need.
