How this is calculated

SV = EV - PV. SPI = EV / PV. Below 1.0 means less work finished than the plan expected by now. The day figure converts the ratio into elapsed time and is an indicator, not a substitute for re-running the schedule.

Frequently asked
Why is schedule variance measured in dollars?

Because earned value measures progress by the budgeted worth of finished work. It is unintuitive at first, which is why the day estimate above exists, but it lets cost and schedule be compared on one scale.

Can SPI be above 1 while the project is still late?

Yes. SPI can look healthy if the easy, cheap work finished early while a critical long-lead item slipped. Always read SPI next to the critical path rather than instead of it.
