💡 Example Calculations to Help You Understand

Example 1: Winning Scenario

  • Entry Fee: $10
  • Prize Won: $50
  • Total Entries: 1000
  • Your Rank: 45

Results:

  • Net Profit: $40
  • ROI: 400%
  • Rank Percentile: Top 95.5%

You made a solid return on your investment and placed in the top 5% of the contest!

Example 2: No Win Scenario

  • Entry Fee: $25
  • Prize Won: $0
  • Total Entries: 500
  • Your Rank: 350

Results:

  • Net Profit: -$25

  • Rank Percentile: Top 30%

You didn’t cash, but you ranked better than 30% of the field — helpful data for long-term strategy.

📊 Why ROI and Percentile Matter in DFS

DFS success is not just about winning big; it’s about long-term profitability. Understanding ROI and rank percentile helps players:

  • Track performance over time
  • Identify profitable contests or strategies
  • Find the best contest types (single-entry vs. multi-entry)
  • Adjust lineups based on historical success
  • Manage bankroll responsibly

The ROI metric is especially important because it tells you how efficiently you’re using your money. Even a small positive ROI over many contests can result in consistent profits.

📌 Additional Tips for Daily Fantasy Sports Players

  • Track Your Entries Weekly: Use a spreadsheet or tool like this calculator to evaluate your weekly or monthly ROI.
  • Start with Single-Entry Contests: These contests are more balanced and less dominated by high-volume players.
  • Compare Contest Types: Use the tool to see which contests give you the best ROI — tournaments, 50/50s, or head-to-heads.
  • Avoid Chasing Losses: Seeing negative ROI? Use your data to pause and reassess before continuing.
