What is a Good Betting Win Rate?
Based on real data from tracked bettors on Gammbler, here is what a good betting win rate actually looks like.
The Data
Based on real betting data tracked on Gammbler across 1,888 bets from 18 scored bettors, the average bettor win rate is 57.6%.
Breakeven Win Rate
For standard -110 odds (the most common line in point spread and over/under betting), the breakeven win rate is 52.4%. This means you need to win more than 52.4% of your bets at -110 odds just to break even after accounting for the sportsbook's vig (juice). Most bettors fall below this threshold.
Win Rate by Bet Type
Win rate benchmarks vary significantly by bet type:
- Moneyline (favorites): Higher win rate (60-70%+) but lower profit per win
- Moneyline (underdogs): Lower win rate (25-40%) but higher profit per win
- Point Spread: ~47-53% for most bettors. Need 52.4%+ to be profitable
- Over/Under: Similar to spreads — ~47-53% for most bettors
- Parlays: Much lower win rate (10-30%) due to compounding odds
- Props: Highly variable — ranges from 40-60% depending on market efficiency
Win Rate by Sport
Based on Gammbler data:
- NFL: Average win rate of 57.8% across 17 scored bettors

- MLB: Average win rate of 58.0% across 8 scored bettors
- SOCCER: Average win rate of 57.9% across 4 scored bettors
- NHL: Average win rate of 56.7% across 4 scored bettors
- CFB: Average win rate of 54.9% across 3 scored bettors
- CBB: Average win rate of 55.5% across 2 scored bettors
What Separates Good from Great
A "good" win rate depends on what odds you are betting. At -110, anything above 53% is solid. At +150, 40% could be highly profitable. The real measure is not win rate alone — it is win rate relative to the odds you are getting. This is why Gammbler's scoring algorithm considers both win rate AND ROI together, rather than ranking bettors by win rate alone.
Frequently Asked Questions
What win rate do I need to be profitable?
At standard -110 odds, you need to win at least 52.4% of your bets to break even. Profitable bettors typically win 53-58% at -110.
Is a 55% win rate good?
Yes. At -110 odds, a 55% win rate produces a roughly 4.5% ROI, which would place you among the top bettors on most platforms.
Why does my win rate not match my profitability?
Win rate alone does not determine profitability. A bettor winning 60% of -300 favorites may be less profitable than a bettor winning 40% of +200 underdogs. ROI is the better profitability measure.
