Like most things in project management, there's usually more than one way to do the same work. I'm happy to report that earned value management works the same way. The formulas I provided previously are accurate, somewhat reliable, and straight out of the PMBOK. However, there are some alternative formulas that you could use to save some of the headaches in memorizing these complex formulas, especially with the ETC and the EAC formulas.
Table 7-1 provides a quick reference for all of these nifty formulas and a mnemonic for memorizing the most common earned value formulas.
