The Arbitrage Calculator helps you calculate how much to stake on different odds from two (or more) sportsbooks to ensure you make a profit—no matter who wins.
If the ROI (Return on Investment) is negative, it means you’ll lose money, so there's no arbitrage opportunity in that case.
Arbitrage betting (also called "surebets," "surewins," or "miraclebets") is a strategy where you bet on all possible outcomes of a sporting event across different betting sites.
By taking advantage of the differences in odds offered by these sportsbooks, you can guarantee profit or at least break even, no matter the result.
In simple terms, you’re betting smartly so you can’t lose money.
Let’s say there’s an NBA game between the Houston Rockets and Cleveland Cavaliers.
Here’s what two different sportsbooks are offering:
Sportsbook A
Houston Rockets: ₦1.50 (odds)
Cleveland Cavaliers: ₦2.50
Sportsbook B
Houston Rockets: ₦1.80
Cleveland Cavaliers: ₦2.20
You could place:
₦55,550 on the Houston Rockets with Sportsbook B, to return ₦100,000
₦40,000 on the Cleveland Cavaliers with Sportsbook A, to also return ₦100,000
Your total stake = ₦95,550, but you’ll receive ₦100,000 no matter who wins. That’s a guaranteed profit of ₦4,450.
This is a classic sports arbitrage opportunity.
There are different ways to apply arbitrage. Here are two common strategies:
Let’s say:
You have ₦100,000
Knicks vs Celtics game
Knicks (Sportsbook Z): -125 odds
Celtics (Sportsbook Y): +150 odds
You place:
₦41,860 on the Celtics at +150
₦58,140 on the Knicks at -125
Returns: ₦104,650 no matter who wins
| Sportsbook | Team | Stake | Return |
|---|---|---|---|
| Z | Celtics (+150) | ₦41,860 | ₦104,650 |
| Y | Knicks (-125) | ₦58,140 | ₦104,650 |
Total Stake: ₦100,000
Profit: ₦4,650 (4.65% ROI)
✅ Safe strategy, perfect for growing your bankroll steadily.
If you have a strong feeling one team will win, you can tweak the stakes to favour that team.
Example:
Celtics (+150): ₦44,440
Knicks (-125): ₦55,560
If Celtics win: Return = ₦111,100 → Profit = ₦11,100 (11.1% ROI)
If Knicks win: Return = ₦100,000 → No profit (Break Even)
| Sportsbook | Team | Stake | Return | Profit Outcome |
|---|---|---|---|---|
| Z | Celtics (+150) | ₦44,440 | ₦111,100 | ✅ Profit = ₦11,100 |
| Y | Knicks (-125) | ₦55,560 | ₦100,000 | ⚠️ Profit = ₦0 (Break Even) |
This is a weighted arbitrage strategy. It's riskier, but useful if you believe strongly in one team winning.
Compare odds across different sportsbooks. It’s slow, but free. Use odds comparison websites to speed things up.
There are online tools that automatically scan for surebets across multiple sportsbooks.
Be careful of fake software—don’t give out your card details to suspicious platforms.
Some betting platforms offer boosted odds or bonus bets. You can use those to create arbitrage opportunities.
⚠️ Tip: Some sportsbooks may ban your account from future promos if you abuse this method. To avoid this:
Use different sportsbooks to balance bets
Place small random bets on different events to seem like a regular bettor
While arbitrage betting is mostly low-risk, it’s not 100% foolproof. Risks include:
Voided Bets: If a sportsbook makes a pricing error (e.g., offering ₦51 odds instead of ₦1.05), they can cancel your bet.
Odds Changing Quickly: Sometimes odds change before you can place both bets, ruining the arbitrage.
Account Restrictions: Bookmakers may limit or ban accounts that constantly place arbitrage bets.
🧠 Key Rule: If the odds seem too good to be true, they probably are.
Arbitrage betting is one of the safest ways to make money in sports betting, but you must be fast, smart, and careful.
Stick to realistic profit margins of 1%–5% and use trusted tools. With discipline, you can turn this into a consistent side income.
