RTP describes a long-run mathematical average. Total wagering can be larger than your deposit. The calculator cannot predict a session or the next outcome.

Your deposit and total wagers

RTP describes the theoretical share of wagers returned as prizes over extensive play. At 96% RTP, the corresponding house edge is 4%. A short session can finish far above or below that average.

A $100 deposit can fund more than $100 in wagers when payouts are played again. If the balance supports $1,000 in total bets, use $1,000 in the expected-loss calculation. Every stake counts toward that total.

For $1,000 wagered at 96% RTP, theoretical return is $960 and expected loss is $40. The calculation is $1,000 × (1 − 0.96).

How it works

Choose the calculator that matches your question. Enter the figures from the game's rules, bonus terms, credit denomination, or your own records. Read the result with its assumptions and worked example.

Cash returned, profit, and taxable winnings measure different things. A total payout can include the original stake. Profit subtracts the stake. The tax calculator uses reportable gambling winnings and eligible losses entered separately.

Keep the same unit throughout a calculation. Convert a credit balance or BTC amount before using it in a dollar-based tool. Copy calculation keeps the inputs, results, and assumptions together for reference.

Common questions

Can a calculator tell me whether the next bet will win?

It can evaluate known probabilities and payout rules. An unrevealed random outcome remains uncertain.

Is RTP the same as the chance of winning?

RTP measures returned money relative to money wagered. Win probability measures how often a specified outcome occurs. Games with the same RTP can pay at different frequencies.

Which game figures should I enter?

Use the RTP, payout convention, denomination, and terms for the exact game or offer you are checking. The result depends on those inputs.
