What is Yield in Sports Betting?
Yield is the industry-standard headline metric: how much profit you make per unit staked. Tipsters quote it, trackers display it, sharps argue about it. Worth understanding both what it measures and where it falls short.
The short definition
Yield is the percentage return on each unit you stake. Expressed mathematically, it’s total net profit divided by total stake, multiplied by 100 to give a percentage.
The headline appeal of yield is that it normalises performance across bettors with different stake sizes. A bettor staking 50u a week and a bettor staking 0.5u a week can still be compared fairly on yield even though their absolute profit numbers will look wildly different.
The formula
Yield % = (Profit ÷ Total Stake) × 100Profit here is net — total returns minus total stake. Total stake is the sum of every individual stake you put down across the period being measured.
Worked example
You placed 100 bets at 1u each. Total stake: 100u. Average odds: 2.00. You won 53 and lost 47.
- Returns from wins: 53 × 2.00 = 106u
- Total stake: 100u
- Net profit: 106 − 100 = 6u
Yield = (6 ÷ 100) × 100 = +6 %You made 6 units of profit per 100 units staked. That would put you in “professional-grade tipster” territory in most sports.
What counts as a good yield?
Rough industry benchmarks, assuming the sample is large enough to be meaningful (1,000+ bets):
- Negative yield: losing money. The vast majority of bettors live here.
- 0 — 2%:breaking even or barely profitable after accounting for the bookmaker’s margin. Many recreational bettors with skill cluster here.
- 2 — 5%: a genuine, sustainable edge. Most professional tipsters in mainstream sports.
- 5 — 10%: excellent. Top-tier tipsters and seasoned sharps usually land here.
- 10%+: exceptional. Sustainable double-digit yield over thousands of bets in major sports markets is rare. Usually indicates either a small sample, a niche edge, or both.
Where yield falls short
Yield is intuitive and easy to compute, which is also why it’s gameable. Things to know:
- It says nothing about bankroll size. A 5% yield from 0.1u stakes is barely worth your phone charger. A 5% yield from 5u stakes is a living. Yield is per-unit-staked, not per-unit-of-life.
- Small samples are extremely noisy.Over 100 bets, a “true” 3% yield bettor will regularly show 8% yield or −2% yield purely from variance. 1,000 bets is the minimum sample for yield to be a credible signal; 5,000+ is where confidence hardens.
- Tipsters can game yield. By varying stake size based on confidence, a tipster can disproportionately credit their wins and discount their losses. Some platforms let tipsters retroactively adjust stakes after a result. Always check whether the stake-size policy is fixed.
- Yield doesn’t prove you have an edge in the future.It’s a historical description. Closing line value (CLV) is the cleaner forward-looking signal because it measures whether you made a good decision independent of whether the bet won.
- Some books limit winning accounts. Real yield in the wild is dragged down by stake caps. The yield you achieved was at the stake you were allowed, not the stake you wanted.
Yield vs ROI vs ROC
These three are often confused. The honest summary:
- Yield: profit divided by total stake. Per-unit-staked measure.
- ROI (Return on Investment):in finance, profit divided by capital invested. In betting, “ROI” is sometimes used as a synonym for yield (stake-based) and sometimes for ROC (bankroll-based). Always check which the source means.
- ROC (Return on Capital): profit divided by the bankroll deployed. Better as a measure of how productively your money is working but harder to compute because bankroll size varies over time.
