ROI, return on investment, is the net profit of a betting record expressed as a percentage of the total amount staked — the headline profitability figure of bet tracking. Yield names the same idea against turnover: yield divides profit by everything that passed through the accounts, ROI by what was actually at risk.
ROI = (net profit / total staked) × 100
Stake $1,000 over a month and end with $1,080, and the ROI is 8%. Stake the same $1,000 and end with $1,020, and it drops to 2%. Because the ratio normalizes profit by volume, records of very different sizes compare on even footing, which is why trackers and tipster services put ROI on every dashboard.
A reporting variant is worth knowing before comparing quotes. Some services express ROI as money returned divided by stake rather than net profit divided by stake: bet $1,000, collect $1,050, and the return form reads 105% against 5% net. The two conventions sit exactly 100 percentage points apart, and the return form is the one Pinnacle’s editorial uses.
ROI vs Yield
ROI and Yield part ways over the denominator. Under even-stake betting the numbers match; they diverge the moment turnover and staked amount are pushed apart by variable stakes, voided bets, cashouts, and exchange commissions, which is where the Yield article explores each case. The rule that travels between tools: ROI compares a history with the money put to risk, yield with the total money that moved.
ROI on Stakes and ROI on Bankroll
ROI against stakes is a per-bet measure of edge. ROI against the bankroll is an account-growth measure, staking-dependent through and through. Turn the bankroll over ten times and a 5% per-stake edge becomes a 50% return on the starting capital; stake each dollar once and the two numbers are identical.
A 12-month record: $5,000 starting bankroll, $50,000 of total stakes, $2,500 net profit.
ROI against stakes: $2,500 / $50,000 = 5%
ROI against bankroll: $2,500 / $5,000 = 50%
Trackers mostly measure against stakes; tools reporting profit against starting capital under the ROI label are quoting the bankroll convention. Before judging a claim of 20% ROI, find out which base produced it — a figure that looks spectacular on the bankroll can be unremarkable on the volume of stakes behind it.
Expected ROI at Fair Prices
Bet at the price the market implies and the expected ROI is zero before the bookmaker margin, negative after it. The expected value of a unit stake combines win probability and price:
expected ROI per unit = (P × odds) − 1
Bet 2.00 on an event you estimate at 55%: 0.55 × 2.00 − 1 = 0.10 — a 10% expected ROI per unit. Set the estimate to the price’s implied probability and the formula lands at break-even, the same line the Hit Rate article draws: ROI turns positive where the win rate clears one divided by the Average Odds. A 60% hit rate on 1.30 favorites loses money; a shallow strike rate on longshots can be deeply profitable. Win rate alone says nothing until the prices enter.
What Real ROI Looks Like
Peer-reviewed data frames the realistic range. According to a study of all 5,136,660 fixed-odds bets placed through New Zealand’s Racing Board between August 2006 and April 2009, the average bet lost about 14.4%, favorites returning −9.78% per bet against −19.00% on longshots, with the most experienced accounts approaching break-even. According to a study of crowd forecasts on Oddsportal, betting when a majority of tipsters backed an outcome returned 1.317% across 68,339 events — one of the rare positive real-world ROIs in the peer-reviewed record.
The practical read: most bettors lose, and a sustained low-single-digit ROI over thousands of bets already sits above nearly everyone. The confidence to attach to any number lives in the sample behind it — the Yield article lays out exactly how many bets a positive figure needs before it stops looking like luck.
What ROI Cannot Tell You
ROI measures the outcome, not the ride. Two bettors can share an 8% ROI while one grinds steady favorites and the other swings through deep drawdowns; Bankroll Charts show the path and the Sharpe Ratio prices the volatility. ROI also says nothing about price quality: a positive number with negative CLV is a bettor running hot, and EV is the forward-looking twin ROI confirms only after settlement.
How Trackers Surface ROI
Every tracker in the wiki reports the figure, but not against the same base. Channels record profit and stakes the way the user logs them, and a positive ROI in one app can print lower in another purely because of how voids, cashouts, and free-bet stakes are settled.
