What yield is in betting and how to calculate it
Yield is the number that separates the feeling of being ahead from the real result. Here is what it measures, how to calculate it properly and how to read it honestly.
The short definition
Yield is the profit you make on every euro staked, as a percentage:
Yield = profit ÷ total staked × 100
If you have staked €6,000 in total and made €180, your yield is 3%: on average, every €100 staked has left you with €3. You can do the sum with the yield calculator.
Why it matters more than profit
Three bettors finish the year with the same profit:
| Bettor | Total staked | Profit | Yield |
|---|---|---|---|
| A | €2,000 | €300 | 15% |
| B | €10,000 | €300 | 3% |
| C | €60,000 | €300 | 0.5% |
All three can say “I made €300”, and all three are telling the truth. But C moved thirty times more money than A to get the same. That does not prove A is better (perhaps A placed few bets and got lucky), but it does show that profit alone does not allow a comparison.
How to calculate it without mistakes
- Gather your full history. Not what you remember: all of it. Memory holds on to wins better.
- Add up the stakes of all settled bets. That is your total staked.
- Work out the profit: what you collected minus what you staked.
- Divide and multiply by 100.
Three cases that tend to cause problems:
- Void bets. Your money is returned, so they stay out of the calculation. Including them would dilute the yield for no reason.
- Cash-out. It counts as a normal bet: the stake placed and what you collected when closing it.
- Bonuses. If you bet with bonus money, your real calculation should separate it. Mixing it in inflates the result, and it will not repeat when the promotion ends.
How to read your yield
Your starting point is negative. Bookmakers build a margin into their odds; a 1X2 on a big match can be around 5%, as you can check with the implied probability calculator. If you bet at random on those markets, your expected yield would be roughly that margin in the negative. So simply getting close to zero already beats the result you would expect from betting with no edge.
Sample size matters. 15% over 50 bets says almost nothing. At odds of 2.00, the standard deviation of yield is about 10 points over 100 bets and about 3 points over 1,000. We go into this in how to tell if a tipster is profitable.
Average odds matter. At high odds the result swings more. Two histories with the same yield are not equally reliable if one bets at 1.50 and the other at 5.00.
Be wary of spectacular yields. A double-digit yield sustained over thousands of bets on liquid markets is very unusual. When someone advertises one, the reasonable thing is to ask for the full, verifiable history.
What to do with the number
Overall yield is only the beginning. What helps is breaking it down: by sport, bookmaker, tipster, bet type and odds range. It is common to discover that one specific part of your history explains almost all the losses, and quite often it is parlays.
Be careful with small breakdowns, though. If you split a thousand bets into twenty categories, some will look very good by chance alone. And a positive yield in the past guarantees nothing in the future: betting always carries risk.
You can do this by hand with our free Excel template, or import your history into BetTracker Pro and get the breakdown without writing formulas.
Frequently asked questions
Are yield and ROI the same?
It depends who is using them. Many websites treat them as synonyms. The clearest approach is to call yield the profit over total staked and ROI the profit over the starting bank, and always to check the formula.
How many bets do you need for yield to mean something?
There is no magic number, because it depends on your average odds. With odds around 2.00, below several hundred bets chance weighs far more than any skill.
Can you live on a 3% yield?
Yield is not a salary. It depends on volume and risk, and it does not guarantee future results. Betting should not be treated as a source of income.
