Yes. Every calculator on iGamingNavigator is completely free, runs in your browser, and requires no signup, account, or download. Nothing you enter is stored.
Enter your bonus amount and the wagering (playthrough) requirement — for example 30x — and the calculator shows the total you must bet before winnings become withdrawable, plus how the deposit vs bonus split affects it.
RTP (Return to Player) is the percentage of wagered money a game pays back over time; the house edge is the casino's share, which is 100% minus the RTP. A slot with 96% RTP has a 4% house edge. Our RTP Calculator estimates both from any published RTP figure.
No. These tools help you understand odds, bonus terms, and bankroll limits so you can make informed decisions — they cannot predict outcomes or beat the house edge. Gambling always carries risk; only ever bet what you can afford to lose.
