Ahead or behind? Know.
Four numbers give you your CPI and SPI, the two indexes that tell you whether the job is over or under budget and ahead or behind schedule. Free, no signup.
CPI = earned value ÷ actual cost. SPI = earned value ÷ planned value. Earned value is your budget times the percent of work physically complete. On both, 1.0 is the line: above 1.0 is under budget or ahead of schedule, below 1.0 is over or behind. Many construction projects run 0.90 to 1.05.
Your numbers
“Actually complete” is your physical progress. “Should be complete” is where the baseline schedule says you should be today.
Earned Value Performance
Both cost and schedule under pressure

The index is where other software stops. It's where POD starts.
A one-time CPI tells you where you stand today. POD reads the daily reports, schedules, and cost files your team already produces and keeps CPI and SPI live on every project, per work package, updated as the work happens, and only from the numbers your data backs.
What CPI means
CPI = earned value ÷ actual cost. A 1.0 means every dollar spent bought a dollar of work. Under 1.0 is over budget; over 1.0 is under budget.
What SPI means
SPI = earned value ÷ planned value. It compares what you have finished against what the baseline schedule expected by today. Under 1.0 is behind.
Earned value
Earned value is budget × percent physically complete. It is the honest measure of progress, not hours logged or invoices sent.
We won't invent numbers you didn't give us.
See these indexes on your own project.
POD turns the reports you already produce into live cost and schedule performance, per work package. As complete as your data, and it shows you what to add.
