What is the difference between SUMPRODUCT and SUMIFS?

SUMIFS is fast and suitable for simple criteria, while SUMPRODUCT is useful for complex criteria and array calculations.

How do I create an OR condition?

You can create an OR condition by using the + operator.

Q: Why is SUMPRODUCT slow?

Because it calculates entire arrays, it becomes slower as the amount of data increases.

The SUMPRODUCT function is a powerful function that can handle multiple criteria through array-based calculations, rather than simply adding values. It is especially flexible for criteria that are difficult to handle with SUMIFS.

📌 Summary

Item	Description
Core function	Multiplies arrays and then sums the results
Main use	Multiple-criteria sums
Alternative function	SUMIFS (simple criteria)
Strength	Flexible criteria handling
Note	Slow with large datasets

1. What Is SUMPRODUCT?

SUMPRODUCT is a function that adds the results of multiplying corresponding values in arrays.

=SUMPRODUCT(array1, array2, ...)

In other words, it calculates as follows:

(A1×B1) + (A2×B2) + (A3×B3)...

2. How It Works (Key Concept)

It converts logical conditions from TRUE/FALSE to 1/0 for calculation.

=SUMPRODUCT((A:A="서울")*(B:B))

👉 If the value is “서울,” it becomes 1; otherwise, it becomes 0, acting as a filter when multiplied.

3. Basic Patterns

✔ Single Criterion

=SUMPRODUCT((A2:A10="서울")*(B2:B10))

✔ Multiple Criteria

=SUMPRODUCT((A:A="서울")*(B:B="완료")*(C:C))

👉 Multiplying additional criteria creates an AND condition.

4. Real-World Example (Order Data)

Data structure

Order ID	Region	Status	Sales
1001	서울	완료	50000
1002	부산	취소	30000
1003	서울	완료	70000

✔ Total Sales for 서울 + 완료

=SUMPRODUCT((B2:B100="서울")*(C2:C100="완료")*(D2:D100))

👉 Result: 120,000

👉 This approach is frequently used for logistics and e-commerce data analysis.

5. SUMIFS vs. SUMPRODUCT

Category	SUMIFS	SUMPRODUCT
Speed	Fast	Slow
Criteria	Simple	Can be complex
Flexibility	Low	High
Recommended for	Basic summaries	Advanced analysis

6. Advanced Uses

✔ OR Criteria

=SUMPRODUCT(((A:A="서울")+(A:A="부산"))*(B:B))

👉 The + operator creates an OR condition.

✔ Text Contains Criterion

=SUMPRODUCT((ISNUMBER(SEARCH("상품",A:A)))*(B:B))

👉 Sums values when a specific text string is included.

7. Important Considerations

Using entire columns (A:A) → slower performance
Mismatched array sizes → errors
Large datasets → Power Query is recommended

👉 Data automation: Power Query Basics

8. Conclusion

SUMPRODUCT is more than a simple function—it can be viewed as a criteria-based data analysis engine.

✔ Complex criteria → SUMPRODUCT
✔ Simple sums → SUMIFS
