### Environment

Tableau Desktop### Resolution

The above steps can be reviewed in the attached workbook "Decile Bins".### Option 1

An IF/ELSEIF calculation can be combined with LODs and the PERCENTILE aggregation. For example, deciles of sales on the individual record/underlying row level looks like this:- Select
**Analysis**>**Create Calculated Field...** - Name the calculated field, enter the following formula and click
**OK**.IF [Sales] <= {PERCENTILE([Sales], .1)} THEN "<10%" ELSEIF [Sales] <= {PERCENTILE([Sales], .2)} THEN "20%" ELSEIF [Sales] <= {PERCENTILE([Sales], .3)} THEN "30%" ELSEIF [Sales] <= {PERCENTILE([Sales], .4)} THEN "40%" ELSEIF [Sales] <= {PERCENTILE([Sales], .5)} THEN "50%" ELSEIF [Sales] <= {PERCENTILE([Sales], .6)} THEN "60%" ELSEIF [Sales] <= {PERCENTILE([Sales], .7)} THEN "70%" ELSEIF [Sales] <= {PERCENTILE([Sales], .8)} THEN "80%" ELSEIF [Sales] <= {PERCENTILE([Sales], .9)} THEN "90%" ELSE "100%" END

### Option 2

If you are looking to compare an aggregate, some modifications will need to be made. For example, if you want to evaluate each customer's decile of sales, the formula will need to look more like this:- Select
**Analysis**>**Create Calculated Field...** - Name the calculated field, enter the following formula and click
**OK**.IF{ FIXED [Customer Name] : SUM( [Sales] ) } <= {PERCENTILE({ FIXED [Customer Name] :SUM([Sales]) }, .1) } THEN "<10%" ELSEIF{ FIXED [Customer Name] : SUM( [Sales] ) } <= {PERCENTILE({ FIXED [Customer Name] :SUM([Sales]) }, .2) } THEN "20%" ELSEIF{ FIXED [Customer Name] : SUM( [Sales] ) } <= {PERCENTILE({ FIXED [Customer Name] :SUM([Sales]) }, .3) } THEN "20%" ELSEIF{ FIXED [Customer Name] : SUM( [Sales] ) } <= {PERCENTILE({ FIXED [Customer Name] :SUM([Sales]) }, .4) } THEN "20%" ELSEIF{ FIXED [Customer Name] : SUM( [Sales] ) } <= {PERCENTILE({ FIXED [Customer Name] :SUM([Sales]) }, .5) } THEN "20%" ELSEIF{ FIXED [Customer Name] : SUM( [Sales] ) } <= {PERCENTILE({ FIXED [Customer Name] :SUM([Sales]) }, .6) } THEN "20%" ELSEIF{ FIXED [Customer Name] : SUM( [Sales] ) } <= {PERCENTILE({ FIXED [Customer Name] :SUM([Sales]) }, .7) } THEN "20%" ELSEIF{ FIXED [Customer Name] : SUM( [Sales] ) } <= {PERCENTILE({ FIXED [Customer Name] :SUM([Sales]) }, .8) } THEN "20%" ELSEIF{ FIXED [Customer Name] : SUM( [Sales] ) } <= {PERCENTILE({ FIXED [Customer Name] :SUM([Sales]) }, .9) } THEN "20%" ELSE "100%" END
