Key Takeaways
- Jackpot funding = coin-in × contribution rate; seed is a one-time floor, not recurring.
- A larger linked bank builds the meter faster than standalone machines.
- Use the build rate to size seed and contribution before certification.

How This Calculator Works
Jackpot funding is a flow problem: coin-in × contribution rate = meter build, plus a one-time seed. This tool lets a licensed operator model a linked progressive from three inputs — linked machine count, daily coin-in per machine, and contribution rate.
Everything runs in your browser. No inputs are transmitted or stored.
The Model
daily_meter = machines × coin_in × rate
seed_funded = seed (one-time)
days_to_target = (target - seed) / daily_meter
The linked bank scales the meter linearly — double the machines, halve the days to any target. The seed is a floor, not a recurring drain.
A Worked Example
50 linked machines, $1,500 coin-in/day each, 1% contribution, $5,000 seed, $25,000 target:
- Daily meter = 50 × 1500 × 1% = $750/day
- Days to target = (25000 − 5000) / 750 ≈ 27 days
- Seed is funded once; the meter then self-sustains from play
Fund Within the Certified Model
Contribution rate and seed are set by the approved math model, not by operator preference. Confirm both with your compliance profile and verify the underlying economics with the slot ROI calculator.

Frequently Asked Questions
What is the contribution rate?
It is the percentage of each wager that feeds the jackpot meter, set by the certified math model. Typical linked progressives contribute 0.5%–2% of coin-in. The rate is approved per market and per order during certification.
What is the seed?
The seed is the minimum the jackpot resets to after a win — a one-time funded floor, not a recurring cost. It is usually a fixed amount agreed in the game's certified configuration.
Why link machines?
A linked bank shares one meter across more coin-in, so the progressive builds faster and reaches higher headlines, which drives play. Standalone machines fund their own slower meter.
Does GOLDPRIME run jackpots?
We build cabinets and platform software that support certified linked progressives for licensed operators, with the jackpot logic scoped per market and per order.
