50/50 Method
EVM Terms
Reviewed by forProject Technology - updated Sep 2026
Quick definition: The 50/50 Method is an earned value technique that earns 50% of a Work Package's or task's budgeted value when it starts, and the remaining 50% when it's completed.
The 50/50 Method is a variation of the Start/Finish method for earning value: 50% of the planned value posts as soon as work begins, and the other 50% posts at completion. It's best suited to shorter-span Work Packages or tasks, generally no more than two reporting periods.
Why it matters
It's a simple middle ground between waiting for full completion and tracking granular percent-complete — useful for short tasks where precise interim measurement isn't practical. Applied to longer Work Packages, though, it can distort earned value, since half the budget is claimed the moment work starts.

FAQ
How is 50/50 different from 0/100?
0/100 waits until full completion to earn any value; 50/50 earns half of the value immediately at actual start and the balance at actual finish.
What's the risk of using 50/50 on a long task?
Because half the budget is earned as soon as the task starts, it can give too much credit if that doesn't match how the work is actually progressing. That can create misleading, false-positive variances.
