This tutorial explains the difference between the SUMIF and SUMIFS functions in terms of their syntax and usage, and provides a number of formula examples to sum values with multiple AND / OR criteria in Excel 365, 2021, 2019, 2016, 2013, 2010, and lower.
As everyone knows, Microsoft Excel provides an array of functions to perform various calculations with data. A few articles ago, we explored COUNTIF and COUNTIFS, which are designed for counting cells based on a single condition and several conditions, respectively. Last week we covered Excel SUMIF that adds values meeting the specified criteria. Now it's time to go over the plural version of SUMIF  Excel SUMIFS that allows summing values by multiple criteria.
Those who are familiar with the SUMIF function might think that converting it to SUMIFS takes just an extra "S" and a few additional criteria. This would seem quite logical… but "logical" it's not always the case when dealing with Microsoft : )
The SUMIF function is used to conditionally sum values based on a single criteria. We discussed the SUMIF syntax in detail in the previous article, so let me give you just a quick summary now.
As you see, the syntax of the Excel SUMIF function allows for one condition only. And still, we say that Excel SUMIF can be used to sum values with multiple criteria. How can that be? By adding the results of several SUMIF functions and by using SUMIF formulas with array criteria, as demonstrated in the examples that follow.
You use SUMIFS in Excel to find a conditional sum of values based on multiple criteria. The SUMIFS function was introduced in Excel 2007 and is available in all subsequent versions of Excel 2010, 2013, 2016, 2019, 2021, and Excel 365.
Compared to SUMIF, the SUMIFS syntax is a little bit more complex:
The first 3 arguments are mandatory, additional ranges and their associated criteria are optional.
sum_range
 one or more cells to sum, required. This can be a single cell, a range of cells or a named range. Only cells with numbers are summed; blank and text values are ignored.criteria_range1
 the first range to be evaluated by the associated criteria, required.criteria1
 the first condition that must be met, required. You can supply the criteria in the form of a number, logical expression, cell reference, text or another Excel function. For example you can use criteria such as 10, ">=10", A1, "cherries" or TODAY().criteria_range2, criteria2, …
 these are additional ranges and criteria associated with them, optional. You can use up to 127 range/criteria pairs in SUMIFS formulas.Notes:
And now, let's have a look at the Excel SUMIFS formula with two conditions. Suppose, you have a table listing the consignments of fruit from different suppliers. You have the fruit names in column A, suppliers' names in column B, and quantity in column C. What you want is to find out a sum of amounts relating to a given fruit and supplier, e.g. all apples supplied by Pete.
When you're learning something new, it's always a good idea to start with simple things. So, to begin with, let's define all the arguments for our SUMIFS formula:
Now assemble the above parameters, and you will get the following SUMIFS formula:
=SUMIFS(C2:C9, A2:A9, "apples", B2:B9, "Pete")
To refine the formula further, you can replace the text criteria "apples" and "Pete" with cell references. In this case, you won't have to change the formula to calculate the quantity of other fruit from a different supplier:
=SUMIFS(C2:C9, A2:A9, F1, B2:B9, F2)
Note. Both the SUMIF and SUMIFS functions are caseinsensitive by nature. To get them to recognize the text case, please see Casesensitive SUMIF and SUMIFS formula in Excel.
Since the aim of this tutorial is to cover all possible ways to sum values by several conditions, we will discuss formula examples with both functions  Excel SUMIFS and SUMIF with multiple criteria. To use them correctly, you need to clearly understand what these two functions have in common and in what way they are different.
While the common part is clear (similar purpose and parameters), the differences are not so obvious, though very essential.
There are 4 major differences between SUMIF and SUMIFS:
For example, SUMIF(A2:A9,F1,C2:C18) will return the correct result because the leftmost cell in the sum_range argument (C2) is right. So, Excel will make the correction automatically and include as many columns and rows in sum_range as there are in range.
A SUMIFS formula with unequally sized ranges will return a #VALUE! error.
Alright, enough strategy (i.e. theory), let's get into the tactics (i.e. formula examples : )
A moment ago, we discussed a simple SUMIFS formula with two text criteria. In the same manner, you can use Excel SUMIFS with multiple criteria expressed by numbers, dates, logical expressions, and other Excel functions.
In our fruit suppliers table, suppose, you want to sum all deliveries by Mike with Qty. 200 or more. To do this, you use the comparison operator "greater than or equal to" (>=) in criteria2 and get the following SUMIFS formula:
=SUMIFS(C2:C9,B2:B9,"Mike",C2:C9,">=200")
Note. Please pay attention that in Excel SUMIFS formulas, logical expressions with comparison operators should always be enclosed in double quotes ("").
We covered all possible comparison operators in detail when discussing Excel SUMIF function, the same operators can be used in SUMIFS criteria. For example, the following formula with return the sum of all values in cells C2:C9 that are greater than or equal to 200 and less than or equal to 300.
=SUMIFS(C2:C9, C2:C9,">=200", C2:C9,"<=300")
In case you want to sum values with multiple criteria based on the current date, use the TODAY() function in your SUMIFS criteria, as demonstrated below. The following formula sums values in column D if a corresponding date in column C falls within the last 7 days, including today:
=SUMIFS(D2:D10, C2:C10,">="&TODAY()7, C2:C10,"<="&TODAY())
Note. When you use another Excel function together with a logical operator in the criteria, you have to use the ampersand (&) to concatenate a string, for example "<="&TODAY().
In a similar fashion, you can use the Excel SUMIF function to sum values in a given date range. For example, the following SUMIFS formula adds the values in cells C2:C9 if a date in column B falls between 1Oct2014 and 31Oct2014, inclusive.
=SUMIFS(C2:C9, B2:B9, ">=10/1/2014", B2:B9, "<=10/31/2014")
The same result can be achieved by calculating the difference of two SUMIF functions, as demonstrated in this example  How to use SUMIF to sum values in a given date range. However, Excel SUMIFS is much easier and more understandable, isn't it?
When analyzing reports and other data, you may often need to sum values corresponding either to empty or nonempty cells.
Criteria  Description  Formula Example  

Blank cells  "="  Sum values corresponding to blank cells that contain absolutely nothing  no formula, no zero length string.  =SUMIFS(C2:C10, A2:A10, "=", B2:B10, "=")
Sum values in cells C2:C10 if the corresponding cells in columns A and B are absolutely empty. 
""  Sum values corresponding to "visually" blank cells including those that contain empty strings returned by some other Excel function (for example, cells with a formula like ="").  =SUMIFS(C2:C10, A2:A10, "", B2:B10, "")
Sum values in cells C2:C10 with the same conditions as the above formula, but includes empty strings. 

Nonblank cells  "<>"  Sum values corresponding to nonempty cells, including zero length strings.  =SUMIFS(C2:C10, A2:A10, "<>", B2:B10, "<>")
Sum values in cells C2:C10 if the corresponding cells in columns A and B are not empty, including cells with empty strings. 
SUMSUMIF or SUM / LEN 
Sum values corresponding to nonempty cells, not including zero length strings.  =SUM(C2:C10)  SUMIFS(C2:C10, A2:A10, "", B2:B10, "")
=SUM((C2:C10) * (LEN(A2:A10)>0)*(LEN(B2:B10)>0)) Sum values in cells C2:C10 if the corresponding cells in columns A and B are not empty, cells with zero length strings are not included. 
And now, let's see how you can use a SUMIFS formula with "blank" and "nonblank" criteria on real data.
Suppose, you have an order date in column B, delivery date in column C and Qty. in column D. How do you find the total of products that have not been delivered yet? That is, you want to know the sum of values corresponding to nonempty cells in column B and empty cells in column C.
The solution is to use the SUMIFS formula with 2 criteria:
=SUMIFS(D2:D10, B2:B10,"<>", C2:C10,"=")
As noted in the beginning of this tutorial, the SUMIFS function is designed with AND logic. But what if you need to sum values with multiple OR criteria, i.e. when at least one of the conditions is met?
The simplest solution is to sum the results returned by several SUMIF functions. For example, the following formula demonstrates how to find the total of products delivered by Mike and John:
=SUMIF(C2:C9,"Mike",D2:D9) + SUMIF(C2:C9,"John",D2:D9)
As you see, the first SUMIF function adds the quantities corresponding to "Mike", the other SUMIF function returns the amounts relating to "John" and then you add these 2 numbers.
The above solution is very simple and may get the job done quickly when there are only a couple of criteria. But a SUMIF + SUMIF formula may grow up enormously if you want to sum values with multiple OR conditions. In this case, a better approach is using an array criteria argument in the SUMIF function. Let's examine this approach now.
You can start by listing all of your conditions separated by commas and then enclose the resulting commaseparated list in {curly brackets}, which is technically called an array.
In the previous example, if you want to sum the products delivered by John, Mike and Pete, your array criteria will look like {"John","Mike","Pete"}. And the complete SUMIF function is SUMIF(C2:C9, {"John","Mike","Pete"} ,D2:D9)
.
The array argument consisting of 3 values forces your SUMIF formula to return three separate results, but since we write the formula in a single cell, it would return the first result only  i.e. the total of products delivered by John. To get this arraycriteria approach to work, you have to use one more little trick  enclose your SUMIF formula in a SUM function, like this:
=SUM(SUMIF(C2:C9, {"John","Mike","Pete"} , D2:D9))
As you see, an array criteria makes the formula much more compact compared to SUMIF + SUMIF, and lets you add as many values as you like in the array.
This approach works with numbers as well as with text values. For instance, if instead of the suppliers' names in column C, you had supplier IDs like 1, 2, 3 etc., then your SUMIF formula would look similar to this:
=SUM(SUMIF(C2:C9, {1,2,3} , D2:D9))
Unlike text values, numbers needn't be enclosed in double quotes in array arguments.
In case, your preferred way is to list the criteria in some cells rather that specify them directly in the formula, you can use SUMIF in conjunction with the SUMPRODUCT function that multiplies components in the given arrays, and returns the sum of those products.
=SUMPRODUCT(SUMIF(C2:C9, G2:G4, D2:D9))
Where G2:G4 are the cells containing your criteria, the suppliers' names in our case, as illustrated in the screenshot below.
But of course, nothing prevents you from listing the values in an array criteria of your SUMIF function if you want to:
=SUMPRODUCT(SUMIF(C2:C9, {"Mike","John","Pete"}, D2:D9))
The result returned by both formulas will be identical to what you see in the screenshot:
If you want to conditionally sum values in Excel not simply with multiple OR conditions, but with several sets of conditions, you will have to use SUMIFS instead of SUMIF. The formulas will be very similar to what we've just discussed.
As usual, an example might help to illustrate the point better. In our table of fruit suppliers, let's add the Delivery Date (column E) and find the total quantity delivered by Mike, John and Pete in October.
The formula produced by this approach includes a lot of repetition and looks cumbersome, but it is easy to understand and, most importantly, it works : )
=SUMIFS(D2:D9,C2:C9, "Mike", E2:E9,">=10/1/2014", E2:E9, "<=10/31/2014") +
SUMIFS(D2:D9, C2:C9, "John", E2:E9, ">=10/1/2014", E2:E9, "<=10/31/2014") +
SUMIFS(D2:D9, C2:C9, "Pete", E2:E9, ">=10/1/2014" ,E2:E9, "<=10/31/2014")
As you see, you write a separate SUMIFS function for each of the suppliers and include two conditions  equal to or greater than Oct1 (">=10/1/2014",) and less than or equal to Oct 31 ("<=10/31/2014"), and then you sum the results.
I've tried to explain the essence of this approach in the SUMIF example, so now we can simply copy that formula, change the order of arguments (as you remember it is different in SUMIF and SUMIFS) and add additional criteria. The resulting formula is more compact than SUMIFS + SUMIFS:
=SUM(SUMIFS(D2:D9,C2:C9, {"Mike", "John", "Pete"}, E2:E9,">=10/1/2014", E2:E9, "<=10/31/2014"))
The result returned by this formula is exactly the same as you see in the screenshot above.
As you remember, the SUMPRODUCT approach differs from the previous two in the way that you enter each of your criteria in a separate cell rather that specify them directly in the formula. In case of several criteria sets, the SUMPRODUCT function won't suffice and you will have to employ ISNUMBER and MATCH as well.
So, assuming that the Supplies Names are in cells H1:H3, Start Date is in cell H4 and End Date in cell H5, our SUMPRODUCT formula takes the following shape:
=SUMPRODUCT((E2:E9>=H4), (E2:E9<=H5), (ISNUMBER(MATCH(C2:C9, H1:H3,0))), D2:D9)
Many people wonder why use double dash () in SUMPRODUCT formulas. The point is that Excel SUMPRODUCT ignores all but numeric values, while the comparison operators in our formula return Boolean values (TRUE / FALSE), which are nonnumeric. To convert these Boolean values to 1's and 0's, you use the double minus sign, which is technically called the double unary operator. The first unary coerces TRUE/FALSE to 1/0, respectively. The second unary negates the values, i.e. reverses the sign, turning them into +1 and 0, which the SUMPRODUCT function can understand.
I hope the above explanation makes sense. And even if it doesn't, just remember this rule of thumb  use the double unary operator () when you are using comparison operators in your SUMPRODUCT formulas.
As you remember, Microsoft implemented the SUMIFS function in Excel 2007. If someone still uses Excel 2003, 2000 or earlier, you will have to use a SUM array formula to add values with multiple AND criteria. Naturally, this approach works in modern versions of Excel 2013  2007 too, and can be deemed an oldfashioned counterpart of the SUMIFS function.
In the SUMIF formulas discussed above, you have already used array arguments, but an array formula is something different.
Let's get back to the very first example where we found out a sum of amounts relating to a given fruit and supplier:
As you already know, this task is easily accomplished using an ordinary SUMIFS formula:
=SUMIFS(C2:C9, A2:A9, "apples", B2:B9, "Pete")
And now, let's see how the same task can be fulfilled in early "SUMIFSfree" versions of Excel. First off, you write down all the conditions that should be met in the form of range="condition". In this example, we have two range/condition pairs:
Condition 1: A2:A9="apples"
Condition 2: B2:B9="Pete"
Then, you write a SUM formulas that "multiplies" all of your range/condition pairs, each enclosed in brackets. The last multiplier is the sum range, C2:C9 in our case:
=SUM((A2:A9="apples") * ( B2:B9="Pete") * ( C2:C9))
As illustrated in the screenshot below, the formula perfectly works in the latest Excel 2013 version.
Note. When entering any array formula, you must press Ctrl + Shift + Enter. Once you do this, your formula gets enclosed in {curly braces}, which is a visual indication that an array formula is entered correctly. If you try typing the braces manually, your formula will be converted to a text string, and it won't work.
Even in modern versions of Excel, the power of the SUM function should not be underestimated. The SUM array formula is not simply gymnastics of the mind, but has a practical value, as demonstrated in the following example.
Suppose, you have two columns, B and C, and you need to count how many times column C is greater than column B, when a value in column C is greater or equal to 10. An immediate solution that comes to mind is using the SUM array formula:
=SUM((C1:C10>=10) * (C1:C10>B1:B10))
Don't see any practical application to the above formula? Think about it in another way : )
Suppose, you have the orders list like shown in the screenshot below and you want to know how many products have not been delivered in full by a given date. Translated into Excel's language, we have the following conditions:
Condition 1: A value in column B (Ordered items) is greater than 0
Condition 2: A value in column C (Delivered) in less than in column B
Condition 3: A date in column D (Due date) is less than 11/1/2014.
Putting the three range/condition pairs together, you get the following formula:
=SUM((B2:B10>=0)*(B2:B10>C2:C10)*(D2:D10<G2))
Well, the formula examples discussed in this tutorial have only scratched the surface of what Excel SUMIFS and SUMIF functions can really do. But hopefully, they have helped pointing you in the right direction and now you can sum values in your Excel workbooks no matter how many intricate conditions you have to consider.
