Tipster ROI Explained is part of Racing Tipster Radar's evidence-first guide to paid and free horse-racing tipping services. Our aim is not to promise winners. It is to help readers understand what a service says it offers, what evidence is available, and which questions still need answering before money is committed.
Tipster ROI Explained
ROI measures profit or loss relative to the amount staked.
Example
If £1,000 is staked across a set of bets and total returns leave £80 profit, the betting ROI is 8%. If the record loses £80, ROI is -8%.
What the number leaves out
A published betting ROI may exclude subscription fees. It can also depend heavily on the odds used to settle the record. Always check the definition before comparing services.
ROI is historical
Even a correctly calculated positive ROI describes a past sample. It is not a promise about the next bet or next year.
Performance claims require evidence. Useful background sources include the UK Gambling Commission's safer-gambling guidance, ASA/CAP gambling and tipster advertising guidance, and structured third-party tip records where methodology is visible. Commercial terms should always be checked on the live merchant checkout.
