(Beta) EVA Calculations when Dated Resource Bill Rates Apply to Assignments and Timecards

Warning:

The dated resource rates feature is Beta functionality in this release of PSA. Do not adopt it except in sandbox environments. Further development is required to deliver a fully functional solution.

For full details of when Estimates Versus Actuals records (EVAs) are generated, see Estimates Versus Actuals. This page uses examples to illustrate how estimated and actual values are calculated on EVAs when dated resource rates are being used by assignments and their related timecards.

For an introduction to dated resource rates, see (Beta) Dated Resource Rates Overview.

Note:

The following example uses hourly bill rates. If you use daily bill rates, estimated and actual values are calculated in the same way. Using hours to days rules is also supported.

Example Scenario

An assignment starts on September 15, 2025 and ends on October 10, 2025. Its schedule specifies five hours worked daily Monday - Friday, and no hours worked Saturday - Sunday. This means that the total working hours per week is 25.

The assignment is using a bill rate card with the following dated resource rates:

Example Dated Resource Rates
Effective Date Rate
September 1, 2025 $100
September 24, 2025 $120

Calculation of Estimated Values

The following table shows the rate that applies each day of the assignment, and how scheduled EVA values are calculated using that information.

Example of Scheduled Value Calculations when Dated Resource Rates are Used
Month Date Rate Scheduled Hours Scheduled Billable Amount Scheduled Bill Rate
(Amount / Hours)
September 2025 15 Monday 100 5 500  
16 Tuesday 100 5 500  
17 Wednesday 100 5 500  
18 Thursday 100 5 500  
19 Friday 100 5 500  
Week 1 Total 25 2,500 2,500 / 25 = 100
22 Monday 100 5 500  
23 Tuesday 100 5 500  
24 Wednesday 120 5 600  
25 Thursday 120 5 600  
26 Friday 120 5 600  
Week 2 Total   25 2,800 2,800 / 25 = 112
29 Monday 120 5 600  
30 Tuesday 120 5 600  
October 1 Wednesday 120 5 600  
  2 Thursday 120 5 600  
  3 Friday 120 5 600  
  Week 3 Total   25 3,000 3,000 / 25 = 120
  6 Monday 120 5 600  
  7 Tuesday 120 5 600  
  8 Wednesday 120 5 600  
  9 Thursday 120 5 600  
  10 Friday 120 5 600  
  Week 4 Total   25 3,000 3,000 / 25 = 120
  September Total   60 6,500 6,500 / 60 = 108.33
  October Total   40 4,800 4,800 / 40 = 120

When EVAs are generated for this assignment, the scheduled values are as shown:

Calculation of Actual Values

By default, actual EVA values are calculated when timecards are submitted or approved.

The following table shows how actual EVA values are calculated for the assignment in the previous table. Timecards are submitted for the hours shown in the Actual Hours column. Notice that no hours are worked on September 19. To make that time up, 2.5 extra hours are worked on both September 24 and September 25.

Example of Actual Value Calculations when Dated Resource Rates are Used
Month Date Rate Actual Hours Actual Billable Amount Actual Average Bill Rate
(Amount / Hours)
September 2025 15 Monday 100 5 500  
16 Tuesday 100 5 500  
17 Wednesday 100 5 500  
18 Thursday 100 5 500  
19 Friday 100 0 500  
Week 1 Total 20 2,000 2,000 / 20 = 100
22 Monday 100 5 500  
23 Tuesday 100 5 500  
24 Wednesday 120 7.5 900  
25 Thursday 120 7.5 900  
26 Friday 120 5 600  
Week 2 Total   30 3,400 3,400 / 30 = 113.33
29 Monday 120 5 600  
30 Tuesday 120 5 600  
October 1 Wednesday 120 5 600  
  2 Thursday 120 5 600  
  3 Friday 120 5 600  
  Week 3 Total   25 3,000 3,000 / 25 = 120
  6 Monday 120 5 600  
  7 Tuesday 120 5 600  
  8 Wednesday 120 5 600  
  9 Thursday 120 5 600  
  10 Friday 120 5 600  
  Week 4 Total   25 3,000 3,000 / 25 = 120
  September Total   60 6,600 6,600 / 60 = 110
  October Total   40 4,800 4,800 / 40 = 120

Now when EVAs are generated for the assignment, the actual values are as shown:

EVA Actual Values Generated for the Preceding Example

When you compare both scheduled and actual values, you can see that the actual values for weeks 1 and 2, and for the month of September, are different from the scheduled values. This is because no hours were worked on September 19 when the rate was $100. Instead, 2.5 extra hours were worked on both September 24 and September 25 when the rate was $120.

EVA Scheduled and Actual Values Generated for the Preceding Example

This illustrates that when hours are moved to after the rate increase, the actual billable amount is greater than the estimated amount because more hours are worked at the higher rate. Moving hours to before the rate increase would have resulted in the actual billable amount being less than the estimated amount because more hours would have been worked at the lower rate.
