# Excel - 4 methods to SUM daily transactions

Your credit card company sends you each month your monthly statement balance.

you can see how much you spent each day.
But sometimes you have more than one transaction per day.
Is there a simple method in Excel by which you can find the answer to this question?
In this post I’m going to demonstrate 4(!) methods. The first three ones are quite common and well-known by the average Excel user. However, the fourth and last is my original invention.
Since I wanted to show a dynamic solution, I am using a Table instead of the more commonly used cell ranges.

The table’s name is CCDebit, and it has only 2 columns: Date and Sum, as can be seen in the following picture:

Table CCDebit

OK, so let’s get down to business.

The first method uses only one function: SUMIF

Method 1 – SUMIF

The second method is a “variation” on the first one. Instead of SUMIF we use SUM and IF:

Method 2 – SUM+IF

Method 3 uses the SUMPRODUCT function

Method 3 – SUMPRODUCT

The fourth and last formula is the most complicated one (My own invention). It combines 5(!) functions as can be seen in the picture:

Method 4 – Five Functions

Explanation:
The formula consists of 2 parts. Each part creates an array, and then both arrays are multiplied to create a single array. Then this array is SUMmed by the SUM function which gives us the final result of the formula.

The first part:

ISNUMBER(MATCH(CCDebit[Date],\$G\$1,0))

returns an array of TRUEs and FALSEs:
TRUE if the argument’s date (\$G\$1) was found in the [Date] column of the table,

Result of the formula’s first part

The second part:

OFFSET(\$A\$1,1,1,COUNTA(CCDebit[Date]),1)

Returns an array of sums, similar in size to the first array:

Result of the formula’s second part

Now, the multiplication of both arrays yields a new array in memory which holds only the sums which belong the parameter date:
multiplication of FALSE (=0) by any number yields 0, of course. And the result of multiplication of TRUE (=1) by any number, is the number itself

Result of  the multiplication

So, now that we have the final array, all that’s left to do is to SUM it.

Simple, isn’t it?
