Arbitrage Calculator
Enter two opposing odds (e.g. Home at Book A, Away at Book B). We tell you the split.
When an arb appears
An arb exists when (1/odds_1) + (1/odds_2) < 1. The tighter the sum, the slimmer the margin. Margins under 1% are common and quickly eaten by fees or limit reductions. We only act on arbs above 2%.
Be aware: books that spot arb accounts may limit or restrict them. Use arbs sparingly and don't turn every account into an arb account.
The editor's notes on this calculator
What this calculator does
Arbitrage (or ‘surebet’) betting is when you can place bets across all outcomes of an event at different operators such that you lock in a profit regardless of the result. Enter the odds offered by each operator on each outcome, plus the total amount you want to deploy. The calculator returns the optimal per-outcome stake and the guaranteed profit.
When it works
True arbitrage requires genuinely different prices on the same event across operators. It is rare: maybe 2 to 5 opportunities per week across the six Nigerian operators we review, and usually at 0.5 to 1.5% margin. Spotting them requires vigilance and a live odds-comparison workflow.
Why Nigerian bettors rarely find arbitrage profitable
Operators cap or close accounts that arbitrage-bet consistently. If you win 3% a week on N50,000 turnover for two weeks, you will be account-reviewed, and likely limited. Real arbitrage is a small-margin, short-horizon game that only works at scale and with constant fresh accounts — not a lifestyle for most.
A more realistic use
Use this calculator to validate that a specific bet at a specific price genuinely has value across operators before you commit. If the numbers do not arb, the market is in line and the bet is a regular value play, not a lock.
