DFS Contest EV Calculator: Expected Value for Any Contest
By Odds Reference Published March 1, 2026 Updated July 19, 2026 Fact-checked by Odds Reference Editorial Editorial Policy
This free calculator finds a DFS contest’s expected value: enter entry fee, field size, payout structure, and estimated cash rate, and it returns EV per entry, break-even cash rate, and rake impact. The math is identical across DraftKings, FanDuel, and any other platform. Run your own numbers in the DFS Contest EV calculator below.

Key Takeaways
- DFS expected value = (cash probability x average payout) - entry fee. Positive EV means the contest is profitable for you over repeated entries.
- Standard DFS rake runs 8-15% of the entry pool depending on platform and contest type. In a 50%-cash double-up at 10% rake, that means the break-even cash rate is ~55.6%, not 50%.
- Cash game break-even is straightforward: about 55.6% win rate at standard 10% rake. GPP break-even depends on your finish distribution across the payout tiers, not a single cash-rate number.
- A consistent 58% cash rate in double-ups generates about $0.88 profit per $20 entry — modest per contest, but roughly $440 across a season of 500 entries.

How Does Rake Affect DFS Expected Value?
Rake is the platform’s cut of every entry fee, taken before any prize money is paid out. DraftKings and FanDuel charge roughly 8-15% depending on contest type and format. This single percentage is the largest structural headwind standing between an average player and long-term DFS profitability.
| Contest Type | Typical Rake | Prize Pool Per $20 Entry | Break-Even Cash Rate |
|---|---|---|---|
| Double-Up (50% cash) | 10% | $18.00 per entry | 55.6% |
| 50/50 (50% cash) | 10% | $18.00 per entry | 55.6% |
| GPP (20% cash) | 15% | $17.00 per entry | Varies by finish |
| Single-entry GPP | 10-12% | $17.60-$18.00 per entry | Varies by finish |
| Head-to-Head | 10% | $18.00 per entry | 55.6% |
In a $20 double-up, 10% rake shrinks the winner’s payout from an even $40 (2.0x) to $36 (1.8x) — the platform keeps $4 of every $40 matched between the two entries. Because you’re paid 1.8x instead of 2.0x for the same win, you need to cash more than half your entries just to break even. Break-even cash rate = entry fee ÷ payout = $20 / $36 = 55.6%, not 50%.

What Is the EV Difference Between Cash Games and GPPs?
Cash games (double-ups, 50/50s) and guaranteed prize pool tournaments (GPPs) both charge rake, but they convert your skill edge into profit through fundamentally different EV profiles — one flat and predictable, the other lumpy, top-heavy, and far more sensitive to field size and payout structure.
Cash games reward consistency. You need to beat roughly half the field to cash, and the payout is relatively flat (1.8-2.0x entry). Break-even analysis is clean: estimate your cash rate, multiply by payout, subtract entry fee.
GPPs reward variance. Top-heavy payout structures mean that first place might win 20% of the total pool while 15th place wins 2x entry. Your EV depends not just on whether you cash, but on how you finish when you do.
| Metric | Cash Game ($20) | GPP ($20, 1000 entries) |
|---|---|---|
| Cash rate needed | 55.6% | N/A (finish matters) |
| 1st place payout | $36 | $3,000+ |
| Min cash payout | $36 | $40 |
| Optimal roster style | Safe, high-floor | Contrarian, high-ceiling |
| Edge from skill | Steady small +EV | Lumpy large +EV |
| Bankroll variance | Low | Very high |
A profitable cash game player who wins 56% of double-ups earns +$0.16 per entry on a $20 contest. Over 500 entries ($10,000 invested), that totals $80 in profit — a 0.8% return on investment.
A profitable GPP player might cash 22% of the time but hit top-10 finishes 2% of the time, generating the majority of profit from rare large payouts. The per-entry EV might be similar to the cash game player, but the variance is dramatically higher.

How Do You Estimate Your Cash Rate?
Your cash rate — the percentage of entries where you finish in the money — is the most important, and hardest to estimate, variable in any DFS EV calculation. Honest self-assessment matters more than any formula, because an inflated estimate turns a real edge into a costly illusion.
Methods for estimating your edge:
- Historical tracking: Record every contest entry, result, and payout for at least 200 entries. Calculate your actual cash rate across cash games and GPPs separately.
- Platform percentile: DraftKings and FanDuel show your historical percentile finish. A consistent top-45% finish rate suggests a cash rate above 55%.
- Field analysis: Assess the skill level of the specific contest. Single-entry contests have harder fields than multi-entry. Low-stakes double-ups tend to have softer fields than high-stakes. Skill is also concentrated: a widely cited McKinsey & Company analysis of DraftKings and FanDuel entry data found that during the first half of the 2015 MLB season, 1.3% of players captured 91% of total profits — meaning your realistic field, in any contest with repeat multi-entry players, includes a small number of opponents with a very large edge.
| Estimated Cash Rate | Per-Entry EV ($20 Double-Up) | Season EV (500 entries) |
|---|---|---|
| 50.0% (average) | -$2.00 | -$1,000 |
| 53.0% (below break-even) | -$0.92 | -$460 |
| 55.6% (break-even) | $0.00 | $0 |
| 58.0% (slight edge) | +$0.88 | +$440 |
| 60.0% (strong edge) | +$1.60 | +$800 |
| 63.0% (elite edge) | +$2.68 | +$1,340 |
The gap between an average player (-$1,000/season) and an elite player (+$1,340/season) is $2,340. That gap is entirely attributable to skill, research, and roster construction quality — not luck, since these figures are per-entry averages over 500 entries.

What Is the Break-Even Formula for Any Contest Structure?
For any DFS contest, the break-even cash rate equals your entry fee divided by your average cash payout — the point where expected value crosses from negative to positive. Cash games use one fixed payout number; GPPs require weighting every finish-tier payout by its probability, which is why GPP break-even is harder to pin down.
Break-Even Cash Rate = Entry Fee / Average Cash Payout
For contests with multiple payout tiers (GPPs), this requires estimating your payout distribution:
Break-Even EV = Sum of (P(finish_i) x Payout_i) - Entry Fee = 0
Our DFS strategy guide covers lineup construction principles that affect where in the payout structure you tend to finish.
FAQ
Q: How do you calculate DFS expected value?
A: DFS expected value equals your estimated cash probability multiplied by the average cash payout, minus the entry fee. For a $20 double-up at 1.8x payout, a 56% cash rate gives EV = (0.56 x $36) - $20 = +$0.16 per entry. The key variable is your skill edge over the field, which sets your cash rate above break-even.
Q: What cash rate do you need to break even in DFS?
A: For cash games (double-ups, 50/50s) with standard 10% rake, the break-even cash rate is approximately 55.6%, not 50%. Rake shrinks the payout from an even 2.0x to about 1.8x, so entry fee divided by payout ($20 / $36) sets the threshold. GPP break-even is more complex — it depends on your finish distribution, not just cash frequency.
Q: Is this DFS EV calculator really free to use?
A: Yes — there is no subscription, account, or paywall. Enter your inputs and it returns EV per entry, break-even cash rate, and rake impact immediately. We haven’t audited every competing tool on the market, but EV estimation is often bundled inside paid DFS subscription packages costing $30-100+ per month; this tool runs the same core math for free.
