Most bettors have no idea what their actual return on investment is. Zort calculates your sports betting ROI automatically — across every bookmaker, sport, and bet type — the moment you scan a slip.
Education
ROI — Return on Investment — is the single most important metric for any sports bettor. It measures how much profit or loss you generate relative to the total amount you stake. Unlike win rate alone, ROI tells you whether you are actually making money over time, not just winning a lot of individual bets.
A bettor with a 60% win rate but poor odds selection can still have a deeply negative ROI. Conversely, a bettor winning only 40% of bets but at the right odds can be consistently profitable. ROI cuts through the noise and shows you the truth.
Professional bettors, tipsters, and analysts all use ROI as their core performance benchmark. It is the sports betting equivalent of the annual return percentage you would track on an investment portfolio.
Breaking it down further:
The total money received back from all settled bets — including your returned stake on winning bets. Losing bets contribute £0 to this figure.
The total amount wagered across all bets in the period, win or lose. Every bet you place contributes to your total staked figure.
Positive = profitable. Negative = losing money. A +5% ROI means for every £100 staked you net £5 profit. A -10% ROI means you lose £10 per £100 staked.
Example
Let's walk through a concrete example so you can see exactly how the ROI formula works in practice.
An 8.5% ROI on £1,000 staked is genuinely excellent — most recreational bettors have a negative ROI. If sustained over 12 months, that's the hallmark of a sharp bettor.
Benchmarks
Context matters. Here is how to interpret your ROI figure against realistic benchmarks.
Most recreational bettors sit at -5% to -15% ROI long-term. Bookmaker margins mean the house wins over large sample sizes. Knowing your ROI is the first step to improving it.
Breaking even or slightly positive is already better than the vast majority of bettors. If you can sustain this across hundreds of bets, you have found a genuine edge.
Professional territory. Consistently achieving 5-15% ROI over 500+ bets is what distinguishes sharp bettors from recreational ones. Very few reach this level.
A +30% ROI after 10 bets is meaningless — that's just variance. ROI becomes statistically meaningful after roughly 200–500 settled bets. Zort tracks every single bet so your ROI figure reflects your true edge, not just a lucky run. The more bets you log, the more reliable your ROI becomes as a signal.

FAQ
Yes. "Returns" in the ROI formula means the total money you receive back from a winning bet — which includes both your profit and your returned stake. Losing bets return nothing, contributing £0 to your returns total.
At least 200 settled bets to start seeing a statistically meaningful signal. Below 100 bets, variance can make a losing bettor look profitable and vice versa. Zort tracks your bet count alongside ROI so you always know how much to trust the number.
Absolutely. Many bettors are profitable in one sport and losing in another — but their blended ROI hides this. Zort's per-sport breakdown is one of the most valuable analytics features because it shows where you have a real edge and where you're overconfident.
Yes — yield is another term for the same calculation. Some tipster services use "yield" rather than "ROI" but the formula is identical: net profit divided by total stakes, expressed as a percentage.
You can manually add historical bets in Zort if you want to build up your full record, or you can start fresh and let Zort capture all new bets via scanning. Either way, your ROI will update automatically as you log results.
