Fixed stake vs percentage bankroll betting
Fixed stake risks the same amount every time; percentage bankroll risks the same share of what you currently hold. They start identically and diverge from the second bet: flat staking measures selection quality cleanly, proportional staking compounds gains and cushions losses.

Head to head
The two plans answer different questions. Flat staking asks how good the selections are. Proportional staking asks how a bankroll grows if those selections are repeated indefinitely.
| Fixed stake | Percentage bankroll | |
|---|---|---|
| Stake basis | Constant €10 | 1% of current balance |
| Winning run | Linear growth | Accelerating growth |
| Losing run | Constant loss per bet | Shrinking loss per bet |
| Ruin risk | Real — balance can reach zero | Asymptotic — stake shrinks with balance |
| Best for | Measuring an edge | Growing a measured edge |
The same twenty bets, two plans
Replay any identical sequence of selections through both plans and the pattern is consistent: after a winning stretch the proportional bankroll is ahead, because later bets were larger. After a losing stretch it is ahead again, because later bets were smaller. In choppy sequences the two finish close together, with flat staking slightly ahead when losses come late.
BetBuddy runs exactly this experiment continuously — the same selections, four separate virtual bankrolls — so the comparison is observable rather than theoretical.
Which one should you use?
If you cannot yet demonstrate an edge over several hundred settled bets, use flat staking: it is the measurement instrument. Once the edge is established and stable, proportional staking is the standard way to convert it into growth.
Betting carries financial risk and no staking plan removes it. Historical performance does not guarantee future results, and BetBuddy runs in paper mode: stakes are simulated and no bookmaker account is connected.
- Still measuring: fixed stake.
- Edge established, want compounding: percentage bankroll.
- Edge established and calibrated: fractional Kelly.
- Chasing a deficit: none of the above — recovery staking increases risk, not edge.
The two plans side by side on the same bets
Run the identical selection sequence through both plans and the difference is entirely in the sizing response. Fixed staking makes every bet a €10 unit regardless of history; percentage staking sizes each bet off the balance that the previous results produced. On a rising sequence the percentage plan pulls ahead through compounding; on a falling one it loses less, because it is betting less.
| Plan | Ending bankroll | Largest stake | Max drawdown |
|---|---|---|---|
| Fixed €10 | €1,020.00 | €10.00 | €40.00 |
| 1% of bankroll | €1,019.10 | €10.30 | €38.90 |
Choosing between them
Use fixed staking when the question is whether the selections have an edge at all: constant units make the profit curve a direct readout of selection quality, uncontaminated by sizing decisions. Use percentage staking when the question is how a bankroll should grow over a long horizon, and when surviving a bad run matters more than maximising a good one.
The plans are not rivals in BetBuddy — both run on the same selections in parallel, precisely so the sizing effect can be separated from the selection effect in the published history.
