SUM time over 9 hours in Excel

In this article, we will learn how to SUM time over 9 hours in Excel.

  1. SUMPRODUCT function
  2. TIME function

Now we will make a formula out of these functions. Here we will given the time value data and we needed sum time values where value is greater than 9 hours.

Use the formula:

= SUMPRODUCT ( ( times - TIME (9,0,0) ) * ( times > TIME (9,0,0) ) )

variables:
times: array of Time values

Let's test this formula via running it on an example
Example:
James has to complete 9 hrs daily but he gets to use the extra time above 9 hrs in the next week.
We have the time record of him for the last 7 days. And for recalculation purpose, we mentioned the extra time for each day.

Here hrs ( D3:D9 ) given in as using named range.

Explanation:

  • TIME (9,0,0) returns the 9:00:00 time value.
  • hrs > TIME (9,0,0) returns the TRUE & FALSE values.
  • hrs - TIME (9,0,0) returns the difference of the actual time value and 9:00 time value
  • SUMPRODUCT function returns the SUM of values given in as array to the function.


As you can see the total extra time he has which he can utilize is 2 hrs and 20 min.

As you can see from the above formula the you can get total sum of time values having criteria.
