Good point. Here's my contribution.

What is ROI and how do I calculate it?

ROI is an acronym for "return on investment" and it is a measure of how many dollars you are earning for each dollar you "invest" in a poker game.

There's two equivalent ways to calculate it:

ROI = (total prize money won)/(total buy-ins + fees) - 1

or

ROI = (net profit or loss)/(total buy-ins + fees)

For example, if I've played 10 50+5 SnGs, and I've won $650 in prize money, my ROI is 650/550-1 or about 18%.
