How this is calculated▾
Total playthrough = bonus × playthrough multiplier. Playthrough applies to the bonus / SC bundle, not the deposit.
Expected loss = total playthrough × (1 − RTP). At 97% RTP you give back 3% of every dollar you play through on average.
Cashback recovered = expected loss × cashback %.
Estimated value = (deposit Sweeps Coins − expected loss + cashback − bundle price. Positive means a profitable buy on average; negative means a losing one.
The likely range uses a normal approximation: variance per spin scales with bet size and volatility, and total variance scales with the number of spins. Real slot distributions are skewed by jackpots, so treat the range as directional, not exact.
Likely range is roughly one standard deviation either side of the estimated value (the middle ~68% of outcomes), with the worst case floored at losing what the bundle cost you.

Frequently asked questions
What is estimated value (EV) on a casino bonus?▾
Estimated value is the average net result of a bonus or playthrough scenario over many repetitions. Positive EV means that on average you finish ahead of your deposit; negative EV means you finish behind. It is not a guarantee for any single session, but it is the long-run average outcome given your inputs.
What is RTP and where do I find it?▾
Return to Player (RTP) is the long-run percentage of wagered money a slot returns to players. A 97% RTP slot returns $97 of every $100 wagered on average, with the remaining $3 being the house edge. Operators publish RTP per game in the help / paytable section. Higher RTP means lower expected loss while clearing playthrough.
How is the playthrough multiplier applied?▾
Playthrough applies to your bonus / SC bundle, not your deposit. If you purchase 50 SC on a site with a 2× playthrough, you must wager 100 SC before redeeming. A 1× playthrough on a sweepstakes site means you wager the bundle once before redemption; online casino bonuses commonly run 20×–40×. Check your operator's terms. A few apply playthrough to deposit + bonus combined.
Why does volatility matter if RTP is the same?▾
Higher volatility means a wider distribution of outcomes around the same estimated value. A 97% RTP low-volatility slot lands you near the average loss most of the time, while a 97% RTP high-volatility slot can wipe out your Sweeps Coins before you finish playthrough, or pay big in rare hits. Volatility doesn't change EV; it changes how far a single run can land from it.
Why doesn't the calculator ask for my bankroll?▾
Because it doesn't change the answer. On a sweepstakes bundle you are washing a fixed number of Sweeps Coins, and the most you can lose is what the package cost. Your balance outside the site has no bearing on whether the offer is worth buying, so the only figures that matter are the price, the Sweeps Coins it gives you, the playthrough, and the RTP you clear it on.
Is positive EV a guarantee of profit?▾
No. Positive EV means the strategy is profitable on average over many trials, not on any single attempt. Variance can produce a losing session even with a strong +EV setup. This calculator is informational only and does not constitute financial or gambling advice.
What is estimated value (EV) on a bonus?
Estimated value (EV) is the average result you'd expect from a bonus or purchase if you played it out many times over. In plain terms, it answers one question: is this offer actually worth it? A positive EV (+EV) means that, on average, you finish ahead. The bonus pays you. A negative EV (−EV) means the math is against you and you'd lose money on average, however any single session happens to go. For sweepstakes and social-casino players, EV is the whole game: it's the line between grinding offers that quietly pay you and ones that quietly cost you.
How to use this calculator
- 1. Enter the bonus. Add your deposit (if any) and the bonus or Sweeps Coins bundle you're getting on top.
- 2. Set the playthrough. How many times you must wager the bundle before you can redeem. 1× on most sweepstakes sites, 20×–40× on typical online-casino bonuses.
- 3. Pick your game's RTP. The return-to-player of the slot you'll clear it on (published in each game's paytable). Higher RTP means lower expected loss.
- 4. (Optional) Fine-tune the risk. Add cashback, your average bet, and volatility to see how wide the realistic range of outcomes gets.
- 5. Read the verdict. The green or red line at the top of the results tells you instantly whether the setup is +EV or −EV, with the exact dollar figure and your realistic cashout. Weighing two offers? Hit “Compare two scenarios” to see them side by side.
Why EV matters for sweepstakes players
The entire edge in sweepstakes and social casinos comes from clearing a low playthrough on a high-RTP game and redeeming what's left. Here's the difference EV makes, with real numbers:
A 50 SC bundle with a 1× playthrough on a 97% RTP slot means you wager 50 SC once and expect to give back about 3%. Roughly 1.5 SC. Leaving about 48.5 SC to redeem. That's a strong +EV setup. Now swap in a 40× playthrough (a typical online-casino bonus) on the same slot: you'd wager 2,000 and expect to lose about 60. Turning the exact same bonus deeply −EV. The calculator runs this math instantly, so you can tell the good offers from the traps before you deposit.
Then put it to work: find the best +EV offers on our sweepstakes casino rankings, stack free coins from the free daily SC list, and cash out at the fastest-paying sites.
