What is roi in fantasy football?
Roi is an acronym that is used in economics, short for return on investment. In fantasy football it means roughly the same thing. It refers to a player performing well based on what they were projected to score or how much an owner invested in them.
How ROI is Measured in Fantasy Football
Roi can be measured in one of two ways. It can be based off of how well your team does in a daily competition (DFS) or based on an individual's performance.
In daily fantasy competitions you pay a buy in amount to be able to compete. That buy in amount factors into what is eventually your roi. What also goes into it is the prize money you win. The more money you win and the less money you spend to enter, the higher your roi.
For example, if you were to enter a competition that requires a 10 dollar entry fee and win 25 dollars then you would have a return on investment of 15 dollars. It can also be written out as a percentage instead. In which case, the roi here would be 150 percent (25 - 10 / 10).
For the most part roi is used to measure a drafted team's success, however roi can also be used to measure how worth it a single player was. In this case the return would be based off of the fantasy points scored and the investment would be the salary paid to the player.
It's a little confusing so here's an example: you spend 10 percent of your salary on one player, and they produce 20 fantasy points. On their own, those values have no meaning, but when compared to other totals from the same competition, a roi can be calculated. To do so you look at the average, so say the average player scores 15 points and costs 10 percent of your salary. The roi would be positive because your player while an average cost, had an above average production.
What is a Good ROI?
A good roi is relative to the amount of experience you have in fantasy sports. A basic rule is that a positive roi is good (making more than you spend). It's also important to factor in that there are service fees which increase the investment number making it harder to have a positive roi.
