# Why don't my Summary Report's billable amounts match the total?

In some cases, you'll generate a [Summary Report](https://track.toggl.com/reports/summary/) that lists [billable amounts](https://support.toggl.com/en-us/article/billable-rates-6jv44s) that don't match up with the total. This is because Toggl Track always rounds up amounts to two decimal places.

Here's an example: We have six Projects. Each Project has an hourly rate of €100, and a total tracked time of 1 minute each.

When billable amounts are computed, hourly rates are converted into cents. So €100/hour becomes ¢10,000/hour.

Each Project is thus worth ¢166.6666667, or €1.6666667:

*1 minute = 0.01666667 hours*  
 *0.01666667 hours x* ¢*10,000 =* ¢*166.6666667*  
¢*166.6666667* ÷ *100 = €1.6666667*

Like on any other service that displays money values, the billable amounts are rounded to two decimal places. So on the Summary Report, the Projects would be listed like so:

When the total amount on the right side of the Summary Report is generated, the set of unrounded ¢166.6666667... values for each Project are summed up for accuracy.

¢*166.6666667 +*  
¢*166.6666667 +*  
¢*166.6666667 +*  
¢*166.6666667 +*  
¢*166.6666667 +*  
¢*166.6666667 =*   
€*1,000 ÷ 100 = €10*

However, manually summing up the values displayed in the Summary Report would result in €10.02. This is because you're adding items that have already been **rounded** up.
