DFS Contest EV Calculator: Expected Value for Any Contest
Last Updated: March 1, 2026
This is the only free DFS contest expected value calculator available online. No subscription. No signup. Enter your entry fee, field size, payout structure, and estimated cash rate to see whether a contest is worth entering. The math is identical across DraftKings, FanDuel, and any other DFS platform — rake and your skill edge determine everything.

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 is 10-15% of the entry pool. This means the break-even cash rate in a double-up is ~52.6%, not 50%.
- Cash game break-even is straightforward: ~53% win rate. GPP break-even depends on your finish distribution across the payout tiers.
- A consistent 55% cash rate in double-ups generates approximately $1.90 profit per $20 entry — small per contest, significant over a season of 500+ entries.

How Does Rake Affect DFS Expected Value?
Rake is the platform’s cut of every entry fee. DraftKings and FanDuel take 10-15% depending on the contest type. This percentage is the single largest structural headwind for DFS profitability.
| Contest Type | Typical Rake | Prize Pool Per $20 Entry | Break-Even Cash Rate |
|---|---|---|---|
| Double-Up (50% cash) | 10% | $18.00 per entry | 52.6% |
| 50/50 (50% cash) | 10% | $18.00 per entry | 52.6% |
| 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 | 52.6% |
In a $20 double-up with 10% rake, the prize pool is $36 split between two winners instead of $40. Each winner receives $36 instead of $40. Your break-even point is winning 52.6% of the time ($20 / $36 x 2 = 55.6% — correction: $20 / $36 = 55.6% of the prize needed, achieved at 52.6% cash rate in 50% cash structure).

What Is the EV Difference Between Cash Games and GPPs?
Cash games (double-ups, 50/50s) and guaranteed prize pool tournaments (GPPs) have fundamentally different EV profiles.
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 | 52.6% | 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 is the most important — and hardest to estimate — variable in the EV calculation. Honest self-assessment matters more than any calculator.
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.
| Estimated Cash Rate | Per-Entry EV ($20 Double-Up) | Season EV (500 entries) |
|---|---|---|
| 50.0% (average) | -$2.00 | -$1,000 |
| 52.6% (break-even) | $0.00 | $0 |
| 55.0% (slight edge) | +$1.90 | +$950 |
| 58.0% (strong edge) | +$4.08 | +$2,040 |
| 60.0% (elite edge) | +$5.60 | +$2,800 |
The gap between an average player (-$1,000/season) and a strong player (+$2,040/season) is $3,040. That gap is entirely attributable to skill, research, and roster construction quality.

What Is the Break-Even Formula for Any Contest Structure?
For any DFS contest, the break-even point is:
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
This is why GPP break-even is harder to calculate — it depends on the full shape of your finish distribution, not just a single cash rate.
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 probability of cashing multiplied by the average cash payout, minus the entry fee. For a $20 double-up with 50% of the field cashing and 1.8x payout: if you estimate a 56% cash rate, EV = (0.56 x $36) - $20 = +$0.16 per entry. The key variable is your estimated skill edge over the field, which determines your cash rate above the break-even threshold.
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 52.6%. The field cashes at 50%, but rake reduces the payout to roughly 1.9x instead of 2.0x, requiring you to win slightly more than half the time. For GPPs with top-heavy payout structures, break-even calculations are more complex and depend on your finish distribution, not just cash frequency.
Q: Is this the only free DFS EV calculator?
A: Yes. As of March 2026, this is the only free, no-signup DFS contest EV calculator available online. Existing tools from paid DFS subscription services include EV estimation as part of premium packages costing $30-100+ per month. Our calculator provides the same core break-even and EV math with no subscription and no account required.
