작동 원리 및 매커니즘.
COUNTIF 함수는 실무 엑셀에서 가장 널리 활용되는 필수 함수입니다. Counts the number of cells within a range that meet a single specified condition or criteria. 대용량 데이터 조회와 자동화된 연산을 지원하여 업무 효율을 극대화합니다.
💡 한눈에 보는 쉬운 설명.
Counts how many cells in a list match a rule you specify, such as counting scores over 75 or orders marked "Yes".
"Think of COUNTIF like a bouncer at a club checking IDs. It looks down your list and counts only the people who meet your rule (e.g. age 21 or over)."

실무 적용 시나리오Count High-Value Transactions
Count how many transactions in column B are greater than or equal to $100.
| Customer | Purchase Amount | Status | Criteria | Count Result |

=COUNTIF()반환 결과의 특성.
Returns number 3 based on sample evaluation criteria and active cell references.
실무 권장 모범 사례
- Use wildcards to find partial text matches: "*east*" matches any cell containing "east".
- When using logical operators with numbers, enclose the operator and number in double quotes: ">=100".
- For case-insensitive counts, COUNTIF automatically ignores uppercase/lowercase differences.
흔히 하는 실수 및 주의사항
- COUNTIF only supports a single condition. If you need to count cells meeting multiple conditions, use COUNTIFS.
- Text strings over 255 characters return incorrect results in COUNTIF.

자주 묻는 질문.
기술 Q&ACan COUNTIF evaluate multiple conditions at once?↓
No, COUNTIF only checks a single condition. To count rows matching multiple simultaneous criteria, use the COUNTIFS function.
How do wildcards work in COUNTIF?↓
You can use an asterisk (*) to match any series of characters (e.g. =COUNTIF(A2:A10, "*East*")) or a question mark (?) to match any single character. To match an actual question mark or asterisk, prepend a tilde (~).
