How Arbitrage Betting Works
Arbitrage betting (arbing) exploits odds differences between bookmakers to guarantee profit regardless of outcome. When different bookmakers price the same event differently, you can bet on all outcomes and lock in profit.
Arbitrage % = (1/Odds1 + 1/Odds2) × 100
If the result is less than 100%, an arbitrage opportunity exists. The lower the percentage, the higher your profit margin.
Example:
Springboks vs All Blacks: Hollywood Bets offers Springboks at 2.10, AfricaSports offers All Blacks at 2.10.
Arbitrage % = (1/2.10 + 1/2.10) × 100 = 95.24%
With R10,000 stake split optimally, you're guaranteed R476 profit regardless of who wins.

How to use this arbitrage calculator
Compare matching outcomes
Use this two-outcome calculator only where the two selections cover every possible settlement outcome. Enter each decimal price and a combined rand stake. A football market with a separate draw option cannot be covered by entering only the two teams. Also check whether extra time counts at both bookmakers.
Illustrative split in rand
Suppose two exhaustive outcomes are each priced at 2.10 and the total allocation is R1,000. Arbitrage exists mathematically when the sum of 1/odds across outcomes is below 1. Here 1/2.10 + 1/2.10 is approximately 0.95238. Split stakes in proportion to 1/odds: each stake equals total allocation × its reciprocal odds divided by that sum. This gives R500 per selection, returning R1,050 from the winning side and leaving R50 after both stakes.
Read the margin carefully
The displayed percentage represents combined implied probability. Below 100% indicates a theoretical margin; exactly 100% leaves none. The example assumes both wagers are accepted unchanged and settled consistently. It is not a live offer. Rounding, stake restrictions, voids or a price movement can erase the calculated surplus.
What if only one wager is accepted?
You have an exposed position rather than a completed arbitrage. Check accepted stakes and prices on each receipt, and avoid chasing the missing side with money beyond your budget.
Should every small margin be pursued?
No. Compare the possible rand gain with operational uncertainty and the funds tied up. Keep records of both tickets together, including settlement rules. Stop if coordinating bets becomes stressful or encourages larger deposits.
