The correct answer is B. .75. The Schedule Performance Index (SPI) equals Earned Value divided by Planned Value; with 30% complete on a $750,000 program against a planned 40%, SPI = $225,000 / $300,000 = 0.75.
Question
You are the program manager for your organization. Your program has a budget of $750,000 and is expected to last one year. The program is currently 30 percent complete and has spent $245,000. The program is supposed to be 40 percent at this time. What is the schedule performance index (SPI) for this program?
Options
- ANegative ten percent
- B.75
- C$300,000
- D$225,000

Why each option
The Schedule Performance Index (SPI) equals Earned Value divided by Planned Value; with 30% complete on a $750,000 program against a planned 40%, SPI = $225,000 / $300,000 = 0.75.
SPI is a dimensionless efficiency ratio, not a percentage difference; 'negative ten percent' is not a valid expression of SPI.
SPI = EV / PV. Earned Value (EV) = 30% x $750,000 = $225,000 and Planned Value (PV) = 40% x $750,000 = $300,000. Dividing EV by PV yields $225,000 / $300,000 = 0.75, indicating the program is progressing at only 75% of the planned schedule rate.
$300,000 is the Planned Value (PV) component of the SPI formula, not the SPI result itself.
$225,000 is the Earned Value (EV) component of the SPI formula, not the SPI result itself.
