ROI Calculator
Use this tool to pressure-test your assumptions before placing real bets. Enter your expected hit rate, average odds, and stake size to see how your return on investment changes over a sample of bets.
Projected outcome
- Total staked
- Expected profit
- Projected ROI
- Break-even hit rate at these odds
How this works
- Expected winners = bets × hit rate.
- Total return from winners = winners × stake × average odds.
- Profit = total return − total staked.
- ROI = (profit ÷ total staked) × 100.
- Break-even hit rate = 1 ÷ average odds.
