You do not need to learn every formula at once. A beginner can become useful by learning a small group of formulas and practicing them with real examples.
1. SUM
Use SUM when you want to add numbers.
Example:
=SUM(B2:B10)
This adds all numbers from cell B2 to B10.
Use it for:
- Adding sales
- Adding expenses
- Adding hours
- Adding marks
- Adding stock totals
2. AVERAGE
Use AVERAGE when you want the usual or middle value from a group of numbers.
Example:
=AVERAGE(C2:C10)
This adds the values and divides by how many numbers are in the range.
Use it for:
- Average test marks
- Average weekly sales
- Average customer ratings
- Average working hours
3. MAX
Use MAX when you want the highest number.
Example:
=MAX(D2:D20)
Use it for:
- Highest sale
- Highest score
- Highest expense
- Most hours worked
4. MIN
Use MIN when you want the lowest number.
Example:
=MIN(D2:D20)
Use it for:
- Lowest sale
- Lowest score
- Smallest payment
- Fewest hours worked
5. COUNT
Use COUNT when you want to count how many cells contain numbers.
Example:
=COUNT(A2:A50)
This is useful when you want to know how many numeric entries are in a list.
6. COUNTA
Use COUNTA when you want to count cells that are not empty.
Example:
=COUNTA(A2:A50)
This can help with attendance lists, customer records, or task trackers.
7. IF
Use IF when Excel needs to make a decision.
Example:
=IF(B2>=50,"Pass","Fail")
This says: if B2 is 50 or more, show Pass. Otherwise, show Fail.
Use it for:
- Pass or fail
- Paid or unpaid
- Complete or incomplete
- Approved or not approved
8. COUNTIF
Use COUNTIF when you want to count only matching cells.
Example:
=COUNTIF(C2:C100,"Paid")
This counts how many cells say Paid.
9. SUMIF
Use SUMIF when you want to add only numbers that match a condition.
Example:
=SUMIF(A2:A50,"Online",B2:B50)
This checks column A for Online and adds the matching numbers in column B.
10. XLOOKUP
Use XLOOKUP when you want to search for something and return a matching result.
Example:
=XLOOKUP(E2,A2:A100,C2:C100)
This looks for the value in E2 inside A2:A100 and returns the matching value from C2:C100.
