CMAT Formula Sheet 2026 :Topic Wise List

The CMAT (Common Managemant Aptitude Test) 2026 is scheduled on 25th January 2026. There are only few day left for the D-day, therefore remembering CMAT quant formulas is very important.

Having formulas on your fingertips not only builds confidence but, increase your speed and accuracy while solving the questions. Read on to know CMAT topic wise formulas here:

✅Percentages

Percentages appear everywhere in CMAT: DI charts, profit-loss, interest, comparisons, and ratio conversions. If your percentage basics are solid, DI becomes faster and less error-prone. Here are the CMAT percentages important formulas to practice:

What you need	Formula
Percentage	(Part / Whole) × 100
x% of y	(x/100) × y
% increase	((New − Old) / Old) × 100
% decrease	((Old − New) / Old) × 100
New value after +x%	Old × (1 + x/100)
New value after −x%	Old × (1 − x/100)
Successive % change	a + b + (ab/100)

✅Ratio, Proportion & Variation

Ratio questions in CMAT are usually straightforward but time-consuming if you don’t set them up quickly. This topic also supports mixtures, ages, partnerships and DI comparisons. Here are the CMAT ratio, proportion and variation important formulas to practice:

Concept	Formula
a:b = c:d	ad = bc
If a:b = m:n	a = km, b = kn
Direct variation	y ∝ x ⇒ y = kx
Inverse variation	y ∝ 1/x ⇒ y = k/x
Split in ratio a:b	Total T ⇒ parts = (a/(a+b))T and (b/(a+b))T

✅Averages & Weighted Average

CMAT frequently tests averages through tables/DI sets, and weighted average is a common trap (people use the simple average by mistake). Mastering this makes DI much cleaner. Here are the CMAT averages important formulas to practice:

Concept	Formula
Average	Sum of observations / Number of observations
New average after adding x	(OldSum + x) / (n+1)
Weighted average	(w1x1 + w2x2 + …) / (w1 + w2 + …)

✅Profit, Loss & Discount

Profit-loss is a CMAT classic because it mixes arithmetic with real-life language. You’ll often see marked price, discount chains, and profit percentage. Here are the CMAT profit, loss and discount important formulas to practice:

What	Formula
Profit	SP − CP
Loss	CP − SP
Profit %	(Profit/CP) × 100
Loss %	(Loss/CP) × 100
SP (profit p%)	CP × (100 + p)/100
SP (loss l%)	CP × (100 − l)/100
Discount	MP − SP
Discount %	(Discount/MP) × 100
MP from SP & discount d%	MP = SP × 100/(100 − d)

✅Simple Interest & Compound Interest

Interest formulas are scoring in CMAT because questions are typically direct. The main time-waster is not remembering the amount/CI relationship. Here are the CMAT simple interest and compound interest important formulas to practice:

Type	Formula
Simple Interest (SI)	(P × R × T)/100
Amount (SI)	P + SI
Compound Amount	A = P(1 + R/100)^T
Compound Interest	CI = A − P

✅Time, Speed & Distance 

TSD is common in CMAT and usually solvable quickly if you know when to use relative speed and average speed formulas (especially in train problems). Here are the CMAT time, speed and distance important formulas to practice:

Topic	Formula
Speed	Distance / Time
Distance	Speed × Time
Time	Distance / Speed
Relative speed (same direction)	|v1 − v2|
Relative speed (opposite direction)	v1 + v2
Avg speed (equal distances)	2xy/(x+y)
The train crosses the pole	Time = Train length / Speed
The train crosses the platform	Time = (Train + Platform length) / Speed

✅Time & Work

This is one of the highest ROI CMAT topics. Most questions boil down to converting “days” into 1-day work and adding rates. Here are the CMAT time and work important formulas to practice:

Concept	Formula
Work	Rate × Time
If A finishes in x days	A’s 1-day work = 1/x
Combined work (A+B)	1/x + 1/y
Time together	xy/(x+y)

✅Mixtures & Alligation

Mixtures come up in CMAT Arithmetic and also inside DI (composition-based sets). Alligation saves time when two components mix into a mean value. Here are the CMAT mixture and alligation important formulas to practice:

Concept	Formula
Mean value	(Σ quantity×value) / (Total quantity)
Alligation ratio	(High − Mean) : (Mean − Low)

✅Number System Essentials

CMAT number system questions are often basic but tricky due to speed. These formulas help in series sums, quick calculations, and divisibility-based questions. Here are the CMAT number system important formulas to practice:

Concept	Formula
Sum 1 to n	n(n+1)/2
Sum of squares	n(n+1)(2n+1)/6
Sum of cubes	[n(n+1)/2]^2
HCF × LCM	Product of two numbers
If a and b are coprime	LCM = a×b

✅Algebra Identities

Algebra in CMAT is usually manageable; identities help you simplify quickly instead of expanding manually (especially in quadratic/expressions). Here are the CMAT algebra identities important formulas to practice:

Identity	Formula
(a+b)²	a² + 2ab + b²
(a−b)²	a² − 2ab + b²
(a+b)(a−b)	a² − b²
(a+b+c)²	a²+b²+c² + 2(ab+bc+ca)
a³−b³	(a−b)(a²+ab+b²)
a³+b³	(a+b)(a²−ab+b²)

✅Logarithms 

Logs aren’t always frequent in CMAT, but when they appear, questions are usually rule-based. If you remember these 5 rules, you’re set.

Rule	Formula
log(ab)	log a + log b
log(a/b)	log a − log b
log(a^b)	b log a
log_a(a)	1
log_a(1)	0
Change of base	log_b a = (log_c a)/(log_c b)

✅Probability 

CMAT probability questions typically focus on fundamental events, unions, intersections, and independence. The key is not overthinking them. Here are the CMAT probability important formulas to practice:

Concept	Formula
Probability	Favourable / Total
Range	0 ≤ P ≤ 1
P(A ∪ B)	P(A)+P(B)−P(A ∩ B)
Independent events	P(A ∩ B) = P(A)P(B)

✅Geometry & Mensuration (2D)

Geometry often feels scary, but CMAT typically asks direct area/perimeter questions. These are must-know formulas for quick wins. Here are the CMAT geometry and mensuration important formulas to practice:

Shape	Area	Perimeter
Square	s²	4s
Rectangle	l×b	2(l+b)
Triangle	½bh	a+b+c
Circle	πr²	2πr
Parallelogram	b×h	2(a+b)
Trapezium	½(a+b)h	a+b+c+d

✅Mensuration 

In CMAT, 3D questions are usually formula-based: plug values and calculate. Learn surface area vs volume clearly to avoid silly mistakes. Here are the CMAT Mensuration important formulas to practice:

Solid	Volume	Surface Area
Cube	s³	6s²
Cuboid	lbh	2(lb+bh+lh)
Cylinder	πr²h	2πr(r+h)
Sphere	(4/3)πr³	4πr²
Cone	(1/3)πr²h	πr(l+r)

✅Coordinate Geometry 

Coordinate formulas are short and high-impact. Even DI sets with graphs sometimes require slope/distance thinking. Here are the CMAT coordinate geometry important formulas to practice:

Concept	Formula
Distance	√[(x2−x1)²+(y2−y1)²]
Midpoint	((x1+x2)/2, (y1+y2)/2)
Slope	(y2−y1)/(x2−x1)
Line	y = mx + c

✅Trigonometry Basics 

CMAT trig is usually basic ratios + standard values. If you know these, you can solve most CMAT-level trig in seconds. Here are the CMAT Trignometry important formulas to practice:

Concept	Formula
sinθ	Opposite / Hypotenuse
cosθ	Adjacent / Hypotenuse
tanθ	Opposite / Adjacent
Key relation	tanθ = sinθ / cosθ
Identity	sin²θ + cos²θ = 1

How to Use This CMAT 2026 Formula Sheet?

Most students “read formulas” but don’t build recall under pressure. Do this instead:

• Step 1: Revise 3 topics/day (10–12 minutes each).
• Step 2: Solve 15 CMAT-level questions right after revision (mix of Arithmetic + DI).
• Step 3: Maintain a “weak formulas list” and revise it daily for 7 days.

This aligns nicely with CMAT’s QTDI-heavy syllabus areas like Arithmetic, Algebra, Geometry and DI sets. 

Why You Need a CMAT Formula Sheet 2026?

A well-structured CMAT 2026 Formula Sheet allows you to revise all important formulas and concepts at a glance. Instead of flipping through multiple books and notes, revising the CMAT Formula Sheet daily ensures better retention and faster recall during the exam.
