- 1Estimate daily wagering volume across your machines — count × average bet × games/hour × hours open.
- 2Apply a contribution rate matched to your desired hit frequency — faster hits need a higher rate.
- 3Project a ceiling from that rate over one full period, seeded at a modest starting fraction.
- 4Average win value is the midpoint of that range — where a mystery jackpot pays out on average.
Calculator questions
How accurate is this calculator?+
It is a planning tool, not an actuarial one. It gives a directionally sound starting point using typical mid-market assumptions for games-per-hour and floor hours. Your exact contribution rate, seed and ceiling should be tuned during a real build to your game math, RTP and regulatory limits.
What is a jackpot contribution rate?+
The percentage of every wager on a linked machine that is diverted into the jackpot pool instead of the base game. Faster desired hit frequencies typically need a higher contribution rate so the pool refills quicker; rarer, larger jackpots can fund more slowly toward a bigger number.
I don't know my games-per-hour or floor hours — does that matter?+
The calculator uses sensible defaults (500 games/hour, 18 hours/day) so you can get a useful estimate immediately. Open "Advanced assumptions" to adjust either figure if you know your own throughput — it changes the estimated daily wagering volume the whole model is built on.
Can Prosperity Gaming build the exact configuration this suggests?+
Yes — send us the numbers from this calculator via the quote form and we will return a tailored contribution structure, seed and ceiling for your venue, matched to your bet range and level structure, within one business day.
