Quick Answer
TL;DR summary
GPP vs Cash EV comparison helps you decide between tournament and cash game formats. Cash games offer ~1.8x payout for top ~45% with lower variance. GPPs offer huge payouts but lower ITM rates. Your expected value in each format depends on your edge - skilled players often have higher EV in one format based on their strengths.
Key Facts About EV
Important things to know
- Cash game EV = (Win Probability × Payout) - Entry Fee
- GPP EV requires estimating finish distribution across payout tiers
- Cash games need ~56% win rate to be +EV after 10% rake
- GPPs can be +EV even with <20% ITM rate if top finishes are frequent
- Your edge should determine format selection
- Variance tolerance matters: Cash = lower, GPP = higher
- Mix both formats based on confidence and bankroll
- Track EV separately by format to find your strengths
Frequently Asked Questions
Common EV questions
What is Expected Value (EV) in DFS?
Expected Value is your average expected return per contest entry over the long run. Positive EV (+EV) means you expect to profit over time. Negative EV (-EV) means you expect to lose. EV = (Probability of Each Outcome × Payout for Each) - Entry Fee.
How do I calculate my edge?
Your edge is how much better (or worse) you perform than average. If you win 55% of cash games (average is ~45% after rake), your edge is +10%. Track results over hundreds of contests to estimate your true edge - small samples are unreliable.
When is GPP +EV over cash?
GPPs become more +EV when: you can consistently finish in top percentiles, your lineups are differentiated enough to hit top payouts, you have ownership leverage advantages, and variance tolerance allows for long losing streaks. Cash is often better for consistent but modest edges.
Does rake affect EV differently?
Rake (typically 10-15%) affects both formats but impacts differently. In cash games, it directly reduces your win rate needed. In GPPs, rake reduces the prize pool but the top-heavy structure means skilled players can still find +EV spots.
How much edge do I need to be profitable?
In cash games with 10% rake and 1.8x payout, you need >55.5% win rate to profit. In GPPs, the math is complex - you can profit with lower ITM rates if your big hits are big enough. Most profitable players have 5-15% edge over the field.
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.
