All Math Excel Formulas: A Complete Beginner-to-Advanced Guide
Microsoft Excel is one of the most powerful tools for calculations, data analysis, and automation. Whether you are a student, business professional, or data analyst, understanding Excel math formulas can save time and improve accuracy.
In this guide, you’ll learn all essential math formulas in Excel, explained in simple language with practical examples.
What Are Excel Math Formulas?
Math formulas in Excel are built-in functions that help you perform calculations such as addition, subtraction, averages, percentages, and more.
All formulas in Excel start with:
=
Example:
=5+3
1. Basic Arithmetic Formulas
These are the foundation of all calculations.
Addition
=A1 + B1
Subtraction
=A1 - B1
Multiplication
=A1 * B1
Division
=A1 / B1
Power
=A1^2
2. SUM Function (Most Used)
Adds a range of numbers.
=SUM(A1:A10)
Adds all values from A1 to A10.
3. AVERAGE Function
Finds the average value.
=AVERAGE(A1:A10)
4. COUNT Functions
Count Numbers Only
=COUNT(A1:A10)
Count Non-Empty Cells
=COUNTA(A1:A10)
Count Blank Cells
=COUNTBLANK(A1:A10)
5. MIN & MAX Functions
Minimum Value
=MIN(A1:A10)
Maximum Value
=MAX(A1:A10)
6. ROUND Functions
Round Number
=ROUND(A1, 2)
Round Up
=ROUNDUP(A1, 2)
Round Down
=ROUNDDOWN(A1, 2)
7. Percentage Formula
=(A1/B1)*100
Or format as percentage:
=A1/B1
8. ABS (Absolute Value)
Removes negative sign:
=ABS(A1)
9. MOD (Remainder)
Returns remainder after division:
=MOD(A1, B1)
10. SQRT (Square Root)
=SQRT(A1)
11. POWER Function
=POWER(A1, 3)
Raises A1 to the power of 3.
12. PRODUCT Function
Multiplies a range:
=PRODUCT(A1:A5)
13. SUMIF & SUMIFS
SUMIF (Single Condition)
=SUMIF(A1:A10, ">10")
SUMIFS (Multiple Conditions)
=SUMIFS(B1:B10, A1:A10, ">10")
14. CEILING & FLOOR
Round Up to Nearest Value
=CEILING(A1, 5)
Round Down
=FLOOR(A1, 5)
15. RAND & RANDBETWEEN
Random Number (0–1)
=RAND()
Random Between Range
=RANDBETWEEN(1, 100)
16. Advanced Math Functions
LOG
=LOG(A1)
EXP
=EXP(A1)
PI Value
=PI()
17. Trigonometry Functions
Sine
=SIN(A1)
Cosine
=COS(A1)
Tangent
=TAN(A1)
18. Matrix Multiplication
=MMULT(A1:B2, C1:D2)
Used for advanced calculations.
