Frequently Asked Questions

Common scratch-off ROI questions

How do I calculate my scratch-off ROI?

ROI = ((Total Winnings - Total Spent) / Total Spent) × 100%. If you spent $50 and won $30, ROI = ((30-50)/50) × 100% = -40%. Track all purchases and wins over time for accurate results.

What is a typical scratch-off ROI?

Most players experience -30% to -50% ROI over time. State lotteries typically return 50-70% of ticket sales as prizes. The remaining 30-50% covers operations, retailer commissions, and state revenue.

Can you have a positive scratch-off ROI?

Yes, but it's uncommon and typically short-term. Variance allows for winning streaks, but over large sample sizes, ROI converges toward the game's expected return rate (negative). Professional advantage players sometimes find +EV situations with near-end games.

Which scratch-off tickets have the best ROI?

Generally, higher-priced tickets ($10-$30) have slightly better return rates than $1-$2 tickets. Games nearing their end date with remaining top prizes may offer better value. Check your state lottery's website for remaining prizes.

How many tickets should I track before calculating ROI?

For meaningful statistical data, track at least 50-100 tickets. Short-term results vary wildly due to variance. A 20-ticket sample could show +50% ROI or -80% ROI and neither would reflect your true expected return.
