How much can you realistically earn?

Arbitrage is the rare betting activity where the profit per bet is locked in advance, so expectations should be MORE precise than in gambling, not less. If a number sounds exciting, check it against the arithmetic below.

The arithmetic #

Your monthly result is approximately: average arb percentage x number of arbs x average stake. Or equivalently: average arb percentage x how many times you turn your bankroll over in a month.

Typical inputs for an active arber: arbs in the 1 to 3 percent range (average around 2), a bankroll that turns over once or twice a week depending on how fast your bets settle. Two turnovers a week at 2 percent is roughly 16 percent on the bankroll in a month.

What actually moves the number #

Four levers, in order of impact:

• Bankroll size: profit scales linearly with it. This is the biggest lever and the least glamorous one.
• Time and speed: more hours at the screen means more arbs caught before they vanish. InPlay especially rewards presence and fast hands.
• Settlement speed: InPlay arbs free your money the same day, PreMatch can lock it until the weekend. Faster settlement = more turnovers.
• Bookmaker health: limited accounts and empty balances silently cut the arbs you can actually take. Account care compounds.

The honest caveats #

Months are not equal. Big tournament weeks produce more arbs; summer breaks produce fewer. Early months run below target while you learn, get verified everywhere and make the beginner mistakes everyone makes.

The percentage also does not scale forever. Very large bankrolls hit bookmaker stake limits and account restrictions, which is why professional arbers plateau and diversify (exchanges, Back/Lay, more books) rather than compound indefinitely.

What it costs in time #

Treat arbing as paid work, not passive income. A realistic starter rhythm is 1 to 3 focused hours per day: scanning, placing, topping up accounts, logging results. The scanner compresses the finding part to seconds; the placing and the money logistics remain yours.

Where to go next #

If the numbers work for you, size your bankroll properly and then learn the mistakes that cost beginners their first month, so you can skip them.
