Schedule performance index = 0.7

Schedule performance index = $70,000 / $100,000
Schedule performance index = 0.7
The Schedule performance index is less than 1 and this indicates that the project performance is unfavorable and behind the schedule for completion .
SPI = 1 (Project on schedule), SPI<1 (Project behind the schedule).
