Sometimes we may want to only sum the visible cells in a filtered list or a table. We may notice that if we use **SUM** function directly with selecting the visible reference in the filtered list, all data in the list (also contains the hidden rows) is included into calculation.

Above all, we need to find a proper function can only sum visible cells in a filtered list and ignore the filtered-out data. Actually, excel built-in **SUBTOTAL** function can perform calculating like sum data, count, average for both visible & invisible cells or only visible cells properly. As we only want to show you the formula to perform sum visible cells in filter list, so in this article we will only introduce you the basic usage of **SUBTOTAL** function on sum data. After reading this article, I think you must have a well understanding of **SUBTOTAL** function, it is flexible for you to use it in your daily work.

**EXAMPLE:**

If we want to sum total amount for the filtered fruit, can we use **SUM** function here directly?

Enter **=SUM(B2:B10)** in B12. See screenshot below, we get 64 here, the returned value is incorrect obviously. It equals to the total amount of the whole list B2:B10, the hidden rows are also taken into calculation.

**FORMULA:**

Let’s apply **SUBTOTAL** function in this case to try to calculate total amount for ‘Apple’ again.

**Step 1:** Enter **=SUBTOTAL(9,B2:B10)**.

**Step 2:** Press **Enter **to load return value.

We can see that this time correct amount 21 is displayed in B12.

**HOW THIS FORMULA WORKS:**

This formula only contains only one function: **SUBTOTAL **function.

**Syntax:**

**=SUBTOTAL (function_num, ref1, [ref2], …)**

It has several arguments like function_num, ref1, ref2. For **function_num**, it is a number, it shows the function used by **SUBTOTAL, **by providing different numbers, SUBTOTAL function can perform different calculation. As we mentioned above, **SUBTOTAL** function can perform most basic calculations like **SUM**, **COUNT**, **AVERAGE**, etc., so we need to know some useful function numbers before explaining **SUBTOTAL **function.

Please see below screenshots, they show the correspondence between number and function.

**Function number from 1 – 101.**

**Function number from 101 – 111.**

Refer to above function number list, we can see that SUM function has two function numbers, **9-SUM** and **109-SUM**. Actually, if we enter 9, **SUBTOTAL** function will only sum visible data and ignore the filtered-out data; and if we enter 109, **SUBTOTAL** function will only sum visible data and ignore the manually hidden data. See, the difference is:

**9: ignore data which is hidden by filter list;**

**109: ignore data which is hidden manually.**

In this instance, in the formula **=SUBTOTAL(9,B2:B10)**. There are two arguments. For the first argument **function_num**, as data is hidden by filter list, so we enter 9 here; for the second argument, **reference**, we can enter the whole list B2:B10, or you can also hold your mouse and select the visible cells directly.

**RESULT:**

We already get proper amount for ‘Apple’, this time let’s pick Banana to check if our formula works properly after changing the filter criteria.

It works properly. **SUBTOTAL** function can work well on ‘sum visible cells’.

**NOTES:**

- If we change
**function_num**from 9 to others, the**SUBTOTAL**function will change calculation accordingly based on the function number. For example, change 9 to 2 in this case (2 – COUNT).

We will get 2 by applying the formula.

**SUBTOTAL**function can ignore all hidden data, so we can also use it to sum visible cells in a range. Just enter the range as the reference, the it will ignore hidden cells in this range.
