# What is the %GT Quick Calculation really?

Using the %GT quick calculation and realising that I couldn't change the name of it, I tried to use the formula that is generally described as the replacement.

`Percentage = SUM(TableName[MyColumn]) / CALCULATE(SUM(TableName[MyColumn]), ALL(TableName))`

However, when I went to use a filter on my report page, I noticed that the formula did not deliver the expected result.

After quickly testing side by side the results of GT% quick calc and the above formula calcuation I worked out only the GT% quick calc was giving me the changed view of my data that I wanted.

Is there anyone who knows what the formula for GT% quick calc is exactly so I can mimic its behaviour in more situations?

As the measure use the ALL() function which returns all the rows in a table, or all the values in a column, ignoring any filters that might have been applied. It's expected that when you check different values from the slicer, the chart values will not change.

Regarding the "Percent of grand total", any filters include slicer, visual/ page/ report level filters will impact values.

In your scenario, you can use ALLSELECTED() function in the measure,

Measure 2 = SUM(Table1[Person count])/CALCULATE(SUM(Table1[Person count]),ALLSELECTED('Table1'))

What I complete the steps that you did I get exactly the same results between the Quick measure and the created measure.

I am unsure how yours is different?

@GilbertQ below is the pic that shows a replication of the problem.  The data file is incredibly simple, the two fields are very simple as well.  When the filter is used the output of the formula and the GT% quick calc is different.

Could I please ask you to try the following formula, and see if that resolves your issue.

```DIVIDE(
sum(Table1[Person count]),
Calculate(
sum(Table1[Person count]),
ALL(Table1)
)
)```

Thank for trying @GilbertQ

The picture below confirms the new formula produces the same result.

Thanx @v-qiuyu-msft!!!

That seems to work, producing the same result as the GT% quick calc.
