How It Works

📊 What is ROI?

ROI (Return on Investment) measures the profitability of your betting activity. It shows how much profit you're making relative to your total stakes.

Example: If you stake $1,000 total and get $1,150 back in returns, your ROI is 15%.

🧮 Calculation Formula

Net Profit = Total Returns - Total Staked
ROI = (Net Profit / Total Staked) × 100
Win Rate = (Wins / Total Bets) × 100

Track Your Bets Automatically

Our platform automatically calculates your ROI, win rate, and performance metrics in real-time.

A betting ROI calculator measures how much profit you generate relative to your total stakes. It is the single most useful metric for evaluating betting performance over time because it strips out stake size and lets you compare results fairly across different bet sizes and periods.

Enter your total stakes and total returns to get your ROI percentage and profit. You can also work backwards to find the total stakes or return needed to hit a target ROI.

How to Calculate Betting ROI

  1. 1
    Enter total stakes — the sum of all bets placed over the period you are measuring.
  2. 2
    Enter total returns — the sum of all winnings received (including returned stakes on winning bets).
  3. 3
    Read your ROI — the calculator shows profit, loss, and ROI percentage. Positive ROI = profitable. Negative = losing.

The ROI Formula Explained

ROI formula

ROI (%) = ((Total returns − Total stakes) ÷ Total stakes) × 100

Example

You placed €2,000 in bets over a month and received €2,180 in returns.

ROI = ((2180 − 2000) ÷ 2000) × 100 = +9%

Profit: €180. A +9% ROI over meaningful volume is strong in matched betting.

Yield vs ROI

ROI measures profit against total investment. Yield measures profit against total stakes without including returned stakes in returns. For matched betting, ROI is more standard.

What Is a Good ROI in Matched Betting?

In matched betting, ROI depends on the type of offers being worked. Sign-up offers typically return 50–80% ROI on the qualifying stake because you are converting a free bet into guaranteed cash. Reload offers and ongoing promotions tend to return 5–20% ROI per offer.

Volume matters more than individual ROI. A 5% ROI on €10,000 in monthly stakes is €500. Using the volume betting calculator helps estimate how many bets you need to hit a target monthly profit.

Common ROI Tracking Mistakes

  • ✕
    Counting stakes as returns. Only count actual winnings received, not your original stake unless it was returned as part of a winning bet.
  • ✕
    Calculating ROI over too few bets. ROI over 10 bets is noise. Over 100+ bets, it becomes meaningful. Short-term variance can make a losing strategy look profitable.
  • ✕
    Ignoring qualifying losses in total stakes. Include every bet placed, including qualifying bets that lost, in your total stakes figure. Otherwise your ROI is inflated.

Frequently Asked Questions

What is ROI in sports betting?

ROI (Return on Investment) measures your profit as a percentage of total stakes. A +5% ROI means for every €100 staked you return €105 on average. It is the standard metric for evaluating betting performance over time.

What is a good ROI in matched betting?

Sign-up offers can generate 50–80% ROI on the qualifying stake. Reload offers and loyalty bonuses typically return 5–20%. The key metric is monthly profit in euros, which depends on both ROI and volume.

How is betting ROI different from yield?

ROI uses total investment (stakes paid out, regardless of outcome) as the denominator. Yield typically refers to profit as a percentage of turnover. In most matched betting contexts the terms are used interchangeably.

Can I calculate expected monthly profit from ROI?

Yes. If your ROI is 8% and you stake €3,000 per month, your expected profit is €240. Use the volume betting calculator to estimate monthly profit based on bet frequency and average stake.
