Progressive Jackpot Simulator – How Does It Work?

Oddsmart’s Progressive Jackpot Simulator is a lightweight, spreadsheet-based tool that turns the glamour of growing jackpot pools into hard numbers.

By entering five simple inputs—your bet size, the slot’s base RTP, the current jackpot amount, the jackpot-hit probability (e.g. 1/1,000,000), and your average spin time—the simulator instantly calculates:

Base EV per Spin (stake × base RTP)

Jackpot EV per Spin (jackpot size × hit probability)

Total EV per Spin (sum of base and jackpot EV)

Spins per Hour (3600 ÷ spin time)

EV per Hour (total EV per spin × spins per hour)

Expected Spins to Hit (1 ÷ hit probability)

Expected Time to Hit (expected spins × spin time ÷ 3600)

These outputs show both your average profit or loss per wager and how long you’d likely play before hitting the big prize. A real-world example—£1 bets on a 95% RTP slot with a £200,000 jackpot at 1-in-2,000,000 odds and 4-second spins—reveals a nominal EV per spin of £1.05 but an expected 2,222 hours (93 days) to win.

This stark contrast highlights how even “positive” EV can mask impractical waiting times.

Whether you’re chasing life-changing payouts or seeking steadier matched-betting returns, this simulator equips you with the EV-versus-effort metrics needed to decide if a progressive jackpot is worth the marathon.
