Quick Answer

TL;DR summary

DFS ROI (Return on Investment) = (Total Winnings - Total Entries) / Total Entries × 100. If you've spent $1,000 on entries and won $1,200, your ROI is +20%. Profitable DFS players typically target 5-15% ROI, though variance means short-term results can vary wildly.

Key Facts About DFS ROI

Important things to know

  • ROI = (Winnings - Entries) / Entries × 100
  • Winning DFS players typically achieve 5-15% long-term ROI
  • GPP variance means 1000+ entries needed for meaningful ROI data
  • Cash game ROI is more stable but capped around 5-10%
  • Platform rake (typically 10-15%) makes positive ROI difficult
  • Track ROI by sport and contest type separately
  • Short-term results are dominated by variance, not skill
  • Sample size of 500+ entries starts to show skill edge

Frequently Asked Questions

Common DFS ROI questions

What is a good DFS ROI?

Long-term ROI of 5-15% is considered very good for serious DFS players. The best players might sustain 15-25% ROI. Remember that platform rake of 10-15% means you need to beat opponents significantly to profit. Most recreational players have negative ROI.

How many entries do I need for meaningful ROI data?

For GPPs, at least 500-1000 entries before drawing conclusions. Cash games require fewer entries (200-300) since variance is lower. Small sample sizes are dominated by luck - one big GPP win or loss can swing ROI dramatically.

Should I track ROI by sport or contest type?

Yes, absolutely. You might be profitable in NFL but losing in NBA, or winning cash games but losing GPPs. Track separately to identify strengths and weaknesses. Focus more volume on your profitable sports/formats.

What causes negative ROI?

Common causes: platform rake (built-in disadvantage), poor player evaluation, bad bankroll management (too much GPP exposure), playing in fields with too many sharks, and variance. Improve by studying, focusing on soft fields, and proper bankroll management.

How does rake affect my ROI?

Platforms take 10-15% rake from prize pools. This means you need to be significantly better than average just to break even. In a 10% rake environment, you need to beat 55% of the field in cash games just to profit.

How this works

Calculations follow the published mathematics of the game — combinatorics for cards, probability theory for dice, and expected-value accounting for wagers. Results are verified against independent references (primarily Wizard of Odds). No calculation here is an opinion or recommendation; it is arithmetic applied to the rules of the game.
