RTP Explainer

Return to Player (RTP) is the theoretical percentage of wagered money a game pays back to players over a very large number of plays.

Try a hypothetical calculation

Expected gross return
£960.00
Expected theoretical cost
£40.00

Turnover is not your deposit

Expected gross return = total wagering × RTP ÷ 100. Theoretical cost is total wagering minus that return, under the same model.

RTP does not promise that a deposit or session returns that percentage. Replayed winnings add to turnover. Actual results can vary greatly, and a game is not due to repay previous losses.

Educational arithmetic only. No calculator makes gambling risk-free or guarantees a return.

RTP describes a mathematical model

Return to player is expected gross return as a percentage of total money staked under a defined game model. A 96% theoretical RTP means £96 expected returns for each £100 of total stakes over that model. It does not promise a refund of 96% of your deposit, a minimum payment or a result within a particular session.

Turnover can be much higher than the starting balance because returned money may be staked repeatedly. A player can lose an entire deposit even when the game’s theoretical RTP is high. A displayed percentage is not a protection against that outcome.

Work through the formula

Expected gross return equals total wagering multiplied by RTP divided by 100. At £1,000 of wagering and 96% RTP, expected returns are £960 and expected net cost is £40. The same-model house edge is 100% minus RTP, here 4%.

This example assumes the supplied figure applies to the exact game, configuration and decisions. It does not estimate the probability of a large win, account for every promotion term or predict when a payment will occur. Actual results can be far above or below the expectation.

Read volatility and rules separately

Two games with equal RTP may have different payment distributions. One may return smaller amounts more often; another may rely on rarer large prizes. A volatility label describes an aspect of that spread but is not a standardised guarantee of session length or maximum loss.

Check the in-game help for the precise version, paytable and any strategy assumptions. A recent losing run does not show that a random game is due to catch up. Do not keep wagering to reach an advertised percentage. Set limits independently of the calculator and stop if gambling creates pressure.

Frequently asked questions

Does 96% RTP mean I keep £96 of a £100 deposit?

No. RTP concerns total stakes under a theoretical model, not a guaranteed deposit balance or personal-session refund.

Can two versions of a game have different RTP?

Yes. Check the specific configuration and rules in the actual game help rather than relying on another version’s figure.
