About this app
RTP Calculator is a free, no-frills tool that reveals the true value behind any sports bet. Enter the odds for each outcome and instantly get the Return To Player (RTP) — the percentage of stakes a bet theoretically returns to players.
WHAT IS THE RTP?
The Return To Player (RTP) is the share of money a betting market gives back to players. It's the flip side of the bookmaker's margin: the higher the RTP, the better your chances of finding interesting odds.
RTP Calculator does the math for you in an instant.
HOW IT WORKS
• Create a bet analysis and enter the odds for each possible outcome.
• Enter each odd in the format shown by your bookmaker — decimal (EU), fractional (UK) or American (US). Convert them in one tap to your preferred format if you like.
• The RTP is calculated instantly, with a color indicator (red to green) to gauge the level of the odds at a glance.
• Save, edit, duplicate or share your analyses anytime.
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 want — perfect for 1X2, correct score bets 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 full betting history.
• Completely redesigned: a fast, clean, dark 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 who compare odds from different bookmakers on the same event.
• Anyone who wants to choose the bets they place more wisely — and, failing to win in the long run, at least lose less.
WHY USE RTP CALCULATOR?
A high RTP means bookmakers take a lower margin on the market — the closer the RTP gets to 100%, the better your chances of finding genuinely interesting odds (what's known in the jargon as a value bet).
Checking the RTP before placing a bet is therefore a fundamental discipline for any serious bettor, or anyone looking to protect their bankroll.
RTP Calculator is first and foremost a decision-support tool. It does not encourage gambling and makes no promise of winnings. Please bet responsibly and only if you are of legal age in your country.
