A good plan turns a big syllabus into a daily number. Enter the days left, chapters remaining, daily study hours, rest days and revision share to see how much to finish each day.
Enter days left and chapters left.
Enter daily hours, rest days and revision share.
Follow the daily target.
Daily target: Topics ÷ (study days × (1 − revision share))
A study planner calculator converts the gap between today and your exam into a daily workload. You enter how many days are left, how many chapters or topics remain, how many hours you can study each day, how many rest days you take per week and what share of the time you want to keep for revision. It returns the number of topics you must finish each day and the hours you can give each topic.
Students preparing for board exams, JEE, NEET, CUET, UPSC prelims or a semester end exam use it to check whether their plan is realistic before they commit to it. A target of 0.8 topics a day feels calm. A target of 2.5 topics a day with only 1.5 hours per topic is a warning that something has to change: more hours, fewer rest days, a smaller revision share or a sharper focus on high-weightage chapters.
1. Count the calendar days left until the exam, D, and the topics or chapters still to be learnt, T.
2. Remove rest days: study days S = D × (7 − rest days per week) ÷ 7.
3. Choose a revision share r as a percentage and set it aside: revision days = S × r ÷ 100.
4. Find the learning days: L = S − revision days, which is the same as S × (1 − r ÷ 100).
5. Daily target = T ÷ L topics per learning day.
6. Time per topic = (L × hours per day) ÷ T. Compare this with how long a chapter actually takes you.
7. If the time per topic is too low, change one input at a time and recompute until the plan fits.
The calculator does not count actual Sundays on a calendar. It assumes your rest days are spread evenly, so each week contributes (7 − rest) study days out of 7. For 90 days with one rest day a week, that is 90 × 6 ÷ 7, about 77.1 study days. The fractional answer is deliberate. It gives the average capacity of the period, which is what matters when you divide a syllabus across it. On paper you can round down to whole days to be safe, but the per-day targets change only slightly.
A common planning error is to spread the syllabus across every available day and hope revision happens somehow. This calculator reserves revision first. If you keep 30% for revision, only 70% of the study days carry new topics, so the daily target rises. Mathematically, Topics ÷ (S × (1 − r)) is larger than Topics ÷ S by a factor of 1 ÷ (1 − r). At 25% revision that factor is 1.33, and at 40% it is 1.67. Keeping this block intact is what lets you take full-length mock tests near the exam.
The daily target alone can mislead, because topics differ in size. Hours per topic, L × h ÷ T, is the better sanity check. It is the average time you can afford for each chapter during the learning phase. If a Physics chapter with numericals usually takes you eight hours and the calculator gives four, the plan will fail however motivated you feel. The model assumes equal-sized topics and steady daily hours. For uneven syllabi, weight heavy chapters as two or three topics each before you enter the count.
Ananya has 90 days left before her Class 12 board exams, 60 chapters across subjects still to finish, can study 5 hours a day, wants to keep 30% of her time for revision and takes one rest day a week.
Study days after rest days: 90 × (7 − 1) ÷ 7 = 77.1 days
Split learning and revision: Revision: 77.1 × 30% = 23.1 days Learning: 54 days
Daily target: 60 ÷ 54 = 1.11 topics/day
Time per topic: 54 × 5 h ÷ 60 = 4.5 hours
Answer: Topics to finish per day 1.11; Hours available per topic 4.5 hours; Revision days 23.1 days
Counting all remaining days as study days and forgetting school, coaching travel, festivals or family functions that also eat time.
Treating every chapter as one topic, even when one chapter is three times longer than another.
Setting the revision share to zero to make the daily target look easier, then running out of time for mock tests.
Entering the hours you wish you could study instead of the hours you have actually managed over the last two weeks.
Not recomputing after falling behind; the target should be updated weekly with the new days and topics left.
Board exam preparation, splitting Physics, Chemistry, Maths or Biology chapters over the months before February or March.
Competitive exams such as JEE, NEET or CUET, where the syllabus is large and fixed.
UPSC, SSC or banking aspirants dividing a list of subjects and current-affairs months across a preparation window.
University semester exams, where a student planning study leave checks whether the gap between papers is enough.
Parents and teachers setting realistic weekly goals for a student who has fallen behind.
How much revision time is enough?
Many toppers keep the last 20–30% of the time for revision and full-length mocks.
What if a topic needs more hours than available?
Increase daily hours, reduce rest days, or prioritise high-weightage chapters.
