Progressive jackpot calculator
Value and break-even threshold
How it works
The jackpot contributes its probability times its cash value to the expected return. Add that contribution to the base return only if the base excludes this jackpot.
At a stake of 1, base RTP of 95% and a 1-in-1,000,000 hit chance, the break-even jackpot is 50,000.
The hit probability must come from game rules, not from meter size. Fixed jackpot, independent spins, no shared prize, tax, meter growth or competing players. Must-hit-by jackpots use a different conditional model.
