Project is running with behind schedule and within Budget
If you want to evaluate how the project is doing with respect to the schedule and budget, you need to calculate CPI and SPI. The first step is to write down the information you have so far: BAC = $550,000, Planned %complete = 45%, actual % complete = 40%, and AC = $175,000.
Now you can calculate PV = BAC x planned% complete = $550,000 x 45% = $247,500.
And you can calculate EV = BAC x actual % complete = $550,000 x 40% = $220,000.
Now you have the information you need to calculate CPI and SPI. CPI = EV / AC = $220,000 / $175,000 = 1.25, which is above 1.0—so your project is within its budget. And you can calculate
SPI = EV / PV = $220,000 / $247,500 = .89, which is below 1.0 – so your project is behind schedule.
