Casino RTP Calculator 2026

Last reviewed: September 1, 2026

Use this casino RTP calculator to convert a game’s published return-to-player percentage into house edge, theoretical return and estimated long-run loss. Enter total wagering rather than only a starting deposit, because money returned during play can be wagered again. The result is a mathematical average—not a forecast of one session.

Important: RTP does not remove gambling risk or show the chance of leaving a session ahead. Actual results can differ substantially because of variance. Confirm the RTP for the exact game version available in your location, set firm limits and never gamble with money needed for essential expenses.

Casino RTP and house-edge calculator

Convert a published RTP into house edge, theoretical return and expected long-run loss. Use the same currency for both money fields. Calculations stay in your browser and are not sent to Latest Casino Promos.

Important: RTP is a theoretical average over a very large number of rounds. This calculator does not predict a session, estimate the chance of winning, model volatility or guarantee that a bankroll will last. Actual results can differ substantially. Gambling involves risk and is for adults of legal gambling age only.

How to use the RTP calculator

  1. Find the published RTP. Open the game’s information or help screen and check the percentage for the exact version you plan to use.
  2. Enter total wagering. Add all wagers placed during the period being modelled, including wagers made with money returned by earlier rounds.
  3. Enter the average wager. This estimates the number of equal-size rounds or spins; it does not change the total expected loss when total wagering stays the same.
  4. Calculate and read the limitations. Treat the figures as long-run averages and not as a session target, bankroll plan or promise of a return.

The calculator is currency-neutral. If the total wagered and average wager are entered in dollars, euros, Canadian dollars, Australian dollars or Norwegian kroner, the monetary outputs use the same unit.

RTP and house-edge formulas

For this calculator, house edge = 100% − RTP. A published 96% RTP therefore corresponds to a 4% theoretical house edge. Theoretical return is total wagering multiplied by RTP, while estimated long-run loss is total wagering multiplied by house edge.

For common table-game and slot examples, use our house-edge comparison by game to see how wheel type, pay tables, commission, game rules and strategy change the percentage.

  • Theoretical return: total wagered × RTP percentage.
  • Estimated long-run loss: total wagered × (100% − RTP).
  • Approximate rounds: total wagered ÷ average wager.
  • Expected loss per average wager: average wager × house edge.

These formulas describe an average across a very large sample. They do not create a smooth loss rate. A short sequence can finish above or below the theoretical return, sometimes by a wide margin.

Illustrations assume the stated RTP remains applicable and show theoretical averages only. They are not promises about a session.

The examples use the same 1,000 units of turnover so the mathematical cost of different RTP inputs is easy to compare. They do not say that a player depositing 1,000 units will receive the theoretical return, because deposit size and total wagering are different measures.

Why total wagering is not the same as a deposit

Total wagering counts every stake. If a person starts with 100 units, places repeated 1-unit wagers and reuses returned funds, the turnover can become much larger than the original 100-unit balance. Expected loss is applied to that accumulated turnover, not simply to the amount first deposited.

This distinction is especially important when comparing bonuses. A wagering requirement can create thousands of units of turnover from a much smaller deposit and bonus. Use our separate casino wagering calculator when the calculation also needs a bonus amount, wagering basis and game-contribution percentage.

RTP, volatility and hit frequency are different

RTP describes a long-run theoretical return. Volatility describes how results may be distributed, such as smaller and more frequent outcomes or larger and less frequent outcomes. Hit frequency measures how often a result classified as a win occurs, but a winning result can still be smaller than the original stake.

Two games can publish the same RTP and still feel very different during play because their prize distributions, feature frequency and volatility differ. A higher RTP does not guarantee a better short session, and a low-volatility label does not make gambling safe or profitable.

Check the RTP source, version and market

  • Open the game information: look for RTP, rules and paytable details inside the live game rather than relying only on a promotional page.
  • Match the exact title and provider: similar names do not prove that two games use the same mathematics.
  • Check for multiple configurations: a provider may make more than one RTP version available to operators.
  • Confirm the active market version: rules and available configurations can differ by operator or jurisdiction.
  • Record the date: game information and availability can change, so recheck before using an old figure.

For a worked example of why the exact configuration matters, use our blackjack rule comparison covering natural payouts, soft 17, doubling, splitting and surrender.

For fixed-probability wheel games, use our roulette wheel and payout comparison to check pocket counts, standard payouts, house edge and zero-rule differences.

For a fixed-rule card-game example, use our baccarat Banker, Player and Tie comparison to check outcome probabilities, commission, payouts and modified variants.

For a strategy-dependent example, use our video poker pay-table comparison to see how 9/6 versus 8/5 payouts, the royal-flush schedule and playing decisions affect theoretical RTP.

For a dice-game comparison, use our craps odds and payout comparison to check line wagers, true Odds payouts, two-dice probabilities and higher-edge proposition bets.

What this calculator cannot tell you

  • whether the RTP displayed by a third-party page matches the live game version;
  • the chance of winning or losing a particular session;
  • how long a bankroll will last;
  • the effect of changing strategy in a skill-influenced game;
  • whether a game contributes to bonus wagering;
  • whether an operator or game is legal or available in your location; or
  • whether identity, payment, withdrawal or promotional rules have been satisfied.

Casino RTP calculator FAQ

Does 96% RTP mean I get 96 back from every 100 wagered?

No. It describes a theoretical return across a very large amount of play. An individual 100-unit sample can return more, less or nothing.

Is RTP always the opposite of house edge?

The calculator uses house edge = 100% − RTP. For games affected by player decisions or rule variations, the applicable return can depend on strategy and the exact rules, so verify what the published percentage assumes.

Can I calculate a reliable RTP from my own session?

You can divide returns by wagers to describe that session, but a small personal sample is not evidence of the game’s long-run theoretical RTP. Short-term variance can dominate the result.

Does a higher RTP mean lower volatility?

No. RTP and volatility measure different characteristics. Games with similar RTP figures can distribute results very differently.

Can this tool calculate bonus playthrough?

Use the dedicated casino wagering calculator for bonus-only versus deposit-plus-bonus requirements, game contribution and estimated qualifying volume. This page focuses on RTP, house edge and expected long-run cost.
