ROI Betting Tool
Calculate your betting return on investment from total staked, returned and bet count.
How to Use This Calculator
- Enter the total amount you have wagered, meaning the sum of every stake
- Enter the total amount returned, counting winning payouts together with the stakes
- (Optional) Add the number of bets you placed to unlock per-bet metrics
- Review your profit, ROI percentage, and per-bet statistics
Formula
Net Profit = Total Returned − Total Wagered
ROI = Net Profit / Total Wagered × 100%
Average Stake = Total Wagered / Number of Bets
Profit per Bet = Net Profit / Number of Bets
Sustained ROIs above 5-10% are typical of strong sports bettors over 1000+ bets; anything above 20% on a small sample is usually variance, not skill.
Frequently Asked Questions
What counts as a good ROI in sports betting?
Professional sports bettors generally target a long-term ROI of 5-10%. Anything beyond 3% across a large sample of 5000 or more bets is regarded as exceptional. Sharps often run thinner at 2-3% on heavier volume, while recreational winners tend to manage 5-15% on smaller volumes accompanied by greater variance.
How does ROI differ from yield?
Yield is simply another label for ROI in a betting context. Both express profit as a percentage of the total wagered, and the terms are interchangeable. Yield is favoured in horse racing and European betting, whereas ROI is more typical in US sports betting and matched betting.
Why does sample size carry so much weight?
Over the short term, ROI is governed by variance rather than skill. A 20% ROI across 50 bets tells you next to nothing, since random variance can manufacture that with ease. To separate skill from luck you usually need 1000 or more bets placed with consistent staking and odds before ROI begins to reflect your genuine edge.
Should I track ROI by sport, market, or bet type?
Absolutely, and each segment deserves its own record. A single headline ROI can disguise the fact that you are profitable on NHL totals yet leaking money on NBA spreads. Granular tracking is the bedrock of any meaningful improvement loop in long-term betting.
