It is not enough to simply memorise a Math formula for CBSE Class 6 to 12 for an exam; the formulas are, in fact, the foundation of every solution you will write. If you are a Class 6 student learning algebra or a Class 12 student preparing for JEE or CBSE board exam 2027, the right formula, used correctly, can make the difference between the smooth flow of a step and a whole page of crossed-out attempts.
Most students look for these formulas in an urgent and hurried manner the night before a test, hopping from one web source to another and finding no assurance which of them covers their current syllabus. Therefore, this guide fixes this issue. It includes all the classes from 6 to 12 and covers the updated CBSE syllabus 2026-27 (with chaining of new NCERT textbooks Ganita Prakash and Ganita Manjari) and provides you with formula chapters, which help you know exactly where to look.

Why CBSE Math Formulas Matter More Than You Think (Especially for 2026–27 Exams)
Consider a formula as a shortcut that mathematicians have developed over hundreds of years to calculate some value, so you don’t have to rederive it yourself. That is where most students go wrong, though: They don’t know the origins of a formula, or when to use it. The understanding and thinking have been the focal point for CBSE to test over and over since 2023, and it will feature again in the 2026- 27 board cycle. The new question pattern to be adopted is not memorisation of the formula, but it is competency-based. Conceptual applications will be accepted.
Important Note: New NCERT Textbooks for 2026–27: What Has Changed?
In Class 6,7,8,9, look closely! Based on NCF-SE 2023 and NEP 2020, the NCERT has new textbooks launched for the session 2026-27. Now the Classes 6, 7 and 8 are using Ganita Prakash, and Class 9 is using Ganita Manjari Part 1. These are not simply “renamed” books, but a style of teaching that is concept-centric, rather than formulaic. Old chapters have been reorganised and renamed; some chapters have been rewritten. This information is updated as needed. The Grade 10th, 11th and 12th continue with the current NCERT textbooks, but with some changes.

Class 6 Maths Formulas – Ganita Prakash (2026–27)
It starts here at CLASS 6. The new book by Ganita Prakash is a hands-on approach. The key chapters are: Perimeter and Area, Fractions and The Other Side of Zero. Area and perimeter formulas for squares, rectangles and triangles are introduced here and will continue to hold to the end of Class 10.

Class 7 Maths Formulas – Ganita Prakash (2026–27)
The most prominent chapters in Class 7 are: Triangles and Their Properties, Simple Equations, and Comparing Quantities. In Class 7, you learned the triangle angle rules, and it is useful to grasp the idea of ratio as you learn more about geometry in Classes 9 and 10. Many students who find it hard in algebra in class 8 or 9 can trace it to the unreliability in solving Simple Equations in this class. But take (take with a grain of salt idiom synonym) that chapter seriously!

Do not rewrite it all in one go; go through it a few days at a time the night before. When combined with previous year papers (2020-25), this can potentially boost your result significantly.

How to Actually Remember CBSE Maths Formulas – Tips That Work in 2026
Let’s get back to something teachers don’t say enough: you don’t memorise formulas by looking at them. They remind you of them by practising them until they feel automatic. These four methods do work.
- Write it, solve it, explain it: When writing a formula write 2 problems with it right away and look for their solutions. Explain it to a younger student and in your own words. This 3-step cycle will help you to remember the formula much better than re-reading.
- Group formulas by concept: Rather than memorising randomly, group related formulas, for example, all area formulas together, all trigonometric identities together, all differentiation rules together. Your brain builds connections between related ideas, which makes recall faster.
- Revisit within 24 hours: The forgetting rate maximises in the first 24 hours following learning. The retention rises by more than 60% if you rewrite a formula the following morning. Provide a 10-minute revision block each morning for formulas you learned the day before.
- Consider using previous year’s question papers: The CBSE question papers from the year 2020 to 2025 are available and exactly give you an idea of which formulas get tested most often. Perusing these papers is quite instructive: some formulas are repeated each year. Prioritise those.
Which CBSE Maths Formulas Are Asked Most Often in Board Exams?
There are some formula topics that come back each year from 2020 to 2025. Following the above analysis, the high-priority formula areas for the CBSE Board exam 2027 are listed below:
- Class 10: Trigonometric ratios and identities, the quadratic formula, AP sum and nth term formula, Heron’s formula, and the distance and section formula in coordinate geometry are the most consistently tested formula sets.
- Class 12: Integration by parts, standard integration formulas, differentiation of composite functions (chain rule), Bayes’ theorem in probability, the equation of a plane in vector form, and inverse trigonometric function properties are asked almost every year. Calculus alone accounts for 35 marks out of 80 in the theory paper.
Insight: Students who lose marks in board exams usually do not lose them because they did not know the formula. They lose marks because they applied the wrong formula in the right situation or forgot to check the condition under which a formula is valid. Always note conditions alongside formulas, not just the formulas themselves.
Final Thoughts: Build Your Formula Bank Early
Students who perform best on Maths board exams and competitive exams have not studied for the highest hours; They have reinforced their formula base throughout their study, and they have a strong base of formulas. This guide provides you with the class-wise structure. Now it’s your turn to put the formulas in, solve problems using them and check them on a regular basis throughout the 2026–27 session.
If you are revising for your class 10th exam or preparing for JEE entrance as in class 11th and 12th, then there are no better formulas than the CBSE maths formulas. Make this guide your personal living formula book this year, add to it, review it and carry it along with you throughout the year.
Frequently Asked Questions (FAQs)
Q1. Are these maths formulas based on the latest CBSE syllabus 2026–27?
Yes. This guide is updated as per the CBSE 2026–27 syllabus, including the new NCERT textbooks Ganita Prakash (Classes 6, 7, 8) and Ganita Manjari (Class 9). Classes 10, 11, and 12 are based on the current NCERT textbooks in use for the 2027 board exams.
Q2. Before the Board Exam, how should a Class 12 student revise all the Maths formulas?
The most effective method is to maintain a dedicated formula notebook, one page per chapter, with the formula, its condition, and one example. Revise this notebook every few days, not all at once. Pair this with solving CBSE previous year papers from 2020 to 2025 to see which formulas are tested most frequently.
Q3. Is the Ganita Prakash syllabus followed by all CBSE schools in 2026–27?
In accordance with NEP 2020 and NCF-SE 2023, most of the CBSE-affiliated schools have used Ganita Prakash books for students of Classes 6, 7 and 8 and Ganita Manjari for students of Class 9. But, some schools may still be in the use of the previous NCERT textbooks. Please check with your school maths teacher for this session on which textbook you are using.
Q4. Can memorising formulas alone help me score well in CBSE maths?
Not anymore. Since the year of 2022, the CBSE exam pattern has definitely undergone a change towards competency-based questions. That is, not only understanding what a formula is, but also when and how one should use it. Memorisation is what starts you out, understanding and application are what add to your score.
Q5. Where can I find CBSE maths formulas for all classes in one place?
This blog from Motion Education is right for that. Here is a chapter-wise formula structure for classes 6 to 12 as per the 2026-27 CBSE syllabus, which will help you practice them in exams. Keep it as a reference for the whole academic year and fill out the formulas as you read through each chapter.
