Question 1

How does the compounding betting calculator work?

Accepted Answer

The calculator multiplies your stake by the odds at each step, then reinvests the entire return as the next stake. Starting with $100 at odds of 1.40, after 28 consecutive wins your total reaches $1,311,701. You can adjust the starting stake and odds using the What-If inputs.

Question 2

What is the probability of winning 28 bets in a row?

Accepted Answer

At a 50% win rate per bet, the probability of winning 28 consecutive bets is approximately 1 in 268,435,456 (0.000000373%). This is a mathematical illustration only and does not represent a viable betting strategy. Never risk money you cannot afford to lose.

Question 3

What odds should I use in the compounding calculator?

Accepted Answer

The default is 1.40 (implied probability ~71%), which represents a strong favourite. Lower odds (e.g. 1.25) reduce the growth rate but increase the theoretical win probability per step. Use the What-If inputs to model any odds between 1.10 and 10.00.

Question 4

Is compounding betting a real strategy?

Accepted Answer

Compounding betting is a mathematical concept, not a guaranteed strategy. While the numbers are mathematically accurate, a losing bet at any step resets your bankroll. This calculator is for educational and entertainment purposes only. Always gamble responsibly.
