Player Retention Prize Pool Split Calculator
Split a tournament or event prize pool across ranked placements with a configurable top-prize share and payout decay. The calculator normalizes the weights so every dollar is assigned, then reports the winner’s payout, the last paid place, and the concentration of the top three awards. It is useful for testing payout structures before publishing event rules.
Calculator
Tournament payout designFormula
Weightᵢ = top weight × decay⁽ⁱ⁻¹⁾
Prizeᵢ = pool × Weightᵢ ÷ Σ(weights)
Prizeᵢ = pool × Weightᵢ ÷ Σ(weights)
What the result means
The main result is the normalized first-place payout. Because all weights are normalized, the pool is fully allocated even when raw weights do not total 100%.
Published payouts may need a rounding adjustment so displayed currency amounts add exactly to the prize pool.
Example calculation
For a $10,000 pool, eight paid places, a 35% starting weight, and 75% decay, normalized first place receives approximately $2,779.83.
Tips for better results
- Check whether the final paid place still covers participation costs.
- Use a lower decay rate for a more top-heavy structure.
- Publish exact rounded payouts before registration closes.
- Reserve taxes or operating costs before entering the prize pool.
- Compare individual and team payout expectations separately.
Frequently asked questions
Why is the first-place payout not exactly the entered top share?
The entered share is a starting weight. All placement weights are normalized so the payouts use the entire pool.
What does payout decay mean?
It is the percentage of the previous placement’s weight assigned to the next placement.
Do the calculated prizes add to the full pool?
Yes before currency display rounding. Published rounded amounts may need a small final adjustment.
Can teams use this prize pool split?
Yes. Treat each paid place as a team, then decide separately how each team divides its award.
Does the calculator deduct taxes or event costs?
No. Enter the net amount actually available for prizes after any deductions.
