RTP Calculator for sports bets

RTP Calculator is a simple, free tool that reveals the true value of any sports bet. Enter the odds for each outcome and instantly get the RTP (Return to Player), the percentage of stakes a bet theoretically returns to players, the rest being the bookmaker's margin. WHAT IS RTP? Return to Player (RTP) is the share of the money a betting market gives back to players. It is the flip side of the bookmaker's margin: the higher the RTP, the greater the chance of finding an attractive price. RTP Calculator does the maths for you in an instant. HOW IT WORKS - Create a bet analysis and enter the odds for every possible outcome. - Enter each price in the format your bookmaker displays — decimal (EU), fractional (UK) or American (US). Convert them to your preferred format in one tap if you wish. - The RTP is calculated instantly with a colour indicator (red to green) so you can judge the odds at a glance. - Save, edit, duplicate or share your analyses at any time. KEY FEATURES - Instant RTP calculation for any sports bet. - All odds formats supported: decimal (EU), fractional (UK) and American (US), with one-tap conversion. - As many outcomes as you need — ideal for 1X2, correct score and complex markets. - Duplicate an analysis in one tap to compare the same bet across several bookmakers and find the best return. - Share your bet analyses as an image. - Save and edit your entire betting history. - Completely redesigned: a dark, fast, uncluttered interface built for bettors. - 100% offline — your data stays on your device. No account, no sign-up. WHO IS IT FOR? - Sports bettors who want to assess the mathematical reality of their bets before placing them. - Bettors comparing odds from different bookmakers on the same event. - Anyone who wants to choose their bets more carefully and, failing to come out ahead in the long run, to lose less. WHY USE RTP CALCULATOR? A high RTP means bookmakers are taking a smaller margin on the market — the closer the RTP gets to 100%, the better the chances of finding a genuinely attractive price because it is mispriced (what the jargon calls a value bet). Checking the RTP before placing a bet is therefore a fundamental discipline for any serious bettor, and for anyone looking to protect their bankroll.
