Compound growth calculator
Geometric growth with full reinvestment
Project bankroll trajectory when every won bet's profit is reinvested into the next.
Why compounding differs from fixed staking
Most bettors stake a fixed percentage of starting bankroll. Compound staking reinvests winnings — meaning your effective stake grows after wins and shrinks after losses. Over long horizons with positive edge, compounding produces dramatically larger returns than flat staking. This calculator shows the difference. Pair with our Bankroll growth simulator for fixed-stake comparison and Kelly criterion for optimal compound fraction.

How to use
- 1Enter starting bankroll.
- 2Enter expected edge per bet (%).
- 3Enter number of bets.
- 4See compound vs flat staking side by side.
Example: 500 bets at 3% edge
Start: €1000. Edge 3%. 500 bets. Compound: ≈€4,500 (4.5x). Flat: ≈€2,500 (2.5x). The difference grows exponentially with N — at 1000 bets compounding gives ≈€20k vs flat ≈€4k.
When to use
- Long-term planning over thousands of bets
- Comparing aggressive vs conservative reinvestment
- Visualizing the math behind 'just stick with it'
