1 Game time
The bankroll sets the risk before the bet
A bankroll is the capital set aside for betting. It should be money that can hit zero without affecting rent, bills or emergency savings.
Bankroll management turns every bet into a share of that capital. One unit at 1% of a $2,000 bankroll is $20. The rule comes before the result, not after a streak.
2 The box score
Three methods, three risk levels
Flat staking keeps the same amount on every bet, based on the starting bankroll. It protects against emotional decisions and makes results easier to read.
Percentage staking follows the bankroll. After a loss, the stake falls; after a win, it rises. Stakes adjust with the bankroll, but recovery takes longer.
Kelly calculates the stake that would grow the bankroll fastest:
Decimal odds (b × p − q) ÷ b
b = decimal odds − 1; p = win probability; q = 1 − p. At a 55% win rate and -110 (1.91) odds, Kelly gives 5.5%; half Kelly gives 2.8%.
Why Kelly is often scaled down
The formula assumes your probability is right. If you think you win 57% of bets while your true rate is 55%, Kelly rises to 9.7%. Over 500 simulated bets, a bettor who overestimates this way drops below half the bankroll in 68.4% of runs.
3 The replay
Stake size changes the path
For the same bettor, stake size does not change the edge. It changes how much time that edge gets to show up. Target: reach +35% before -20%, at -110 (1.91) odds.
Exact calculation, no random sampling. Flat stakes on starting bankroll.
A smaller stake helps the bankroll last longer. A short deadline often forces larger staking.

The turning point
Same bettor, two bankrolls
If your edge exists, bankroll size decides stake size. The return is not guaranteed, but the same 2% is a bigger dollar amount.
On $100,000 funded: $2,000 stakes, an average gain of $8,000 after the split.
Assumptions: a 5% return per unit staked, 100 bets a month, stakes of 2% of the bankroll. An average, not a guarantee: a month can end down. Prime Sports Funded shows its bankroll in US dollars.

5 Overtime
In a challenge, rules frame the bankroll plan
A prop firm adds two constraints: a stake range and a loss limit. Across the English-language operators we cover, published stake caps range from 1% to 10% depending on the offer, with drawdown limits that can end the challenge.
At a 5% stake, two losses in one day can be enough to hit a 10% daily limit. At 2%, it takes five. Bankroll management also keeps you inside the rules.

How we calculate
- Three profiles: 54% of bets won and 2 bets a day; 55% and 3; 57% and 4.
- Each operator is modeled at the stake that gives it the best chance, within its allowed range.
- Time-limited challenge: the number of bets is capped by the profile's pace.
- Several phases: the chances multiply.
- Not simulated: daily loss limits, minimum number of bets, activity targets, consistency rules.
- Bankroll U is taken at its Combine, the lowest real cost among the offers considered for this matchup, on the steady profile. Five levels: not ranked (higher real cost on the steady profile).
- Bankroll U: Combine only, which opens the Rookie level at 10% of profits.
- Fan Funded is taken at its 3 Step, the lowest real cost among the offers considered for this matchup, on the steady profile. 2 Step: not ranked (higher real cost on the steady profile). Blitz: not ranked (too close to call: the gap depends on the exchange rate).
- GetBet Funded: price shown with the operator's 20% discount, no published end date.
- Prime Sports Funded price with code PROMO25.
- Amounts are shown in each operator's own currency, with no conversion. Operators are not ranked across currencies.
- The math holds for these profiles, not for every bettor.
Frequently asked questions
How much should you stake per bet?
A 1% to 2% stake is the safer range when your edge is not measured precisely. With flat stakes based on starting bankroll, eight straight losses at 2% cost 16% of the bankroll. At 5%, the same run costs 40%.
Should you raise your stake after a loss?
No. Raising the stake to win it back increases risk at the worst point. A flat stake, or a fixed share of bankroll, removes that decision after the result.
What is the Kelly criterion?
Kelly gives a theoretical stake from your win probability and the odds. At a 55% win rate and -110 (1.91) odds, it gives 5.5%. It becomes dangerous when the win probability is overstated.
What stake should you use in a prop firm challenge?
The stake allowed by the rules, then the lowest one that still leaves a path to the target. With no time limit, 2% gives more room. With 30 days, the stake often has to move higher.
Final score
Pick the challenge that gives you time
Compare real cost, deadline and drawdown before paying. A larger bankroll does not remove risk; it changes the size of each decision.
