Strike Rate Calculator
Work out your strike rate and compare it with the break-even rate the odds you bet at actually demand.
A strike rate calculator works out what share of your bets win, and crucially, compares that rate with the break-even percentage that the odds you bet at actually demand, because a strike rate alone tells you almost nothing about profit.
What Is a Strike Rate?
Strike rate is the share of your bets that win, expressed as a percentage. It is the simplest measure of betting performance, and also one of the most misleading when quoted alone. A strike rate of 39.2% sounds reasonable — until you learn it requires 3.00 odds to be profitable (33.3% break-even), and fails to break even at 2.00 (50.0% break-even). Strike rate means nothing without the odds beside it.
Strike rate is distinct from two other record measures. Win-loss records simply count wins and losses after the fact, giving you the full picture of past results. Streak probability tells you how likely a run is at your strike rate. Strike rate itself measures just the rate — the share of winners in your sample — without reference to what you backed or at what prices. This separation matters because a strike rate on its own can be misleading. A bettor can improve their strike rate by backing shorter odds and still lose money overall, because short odds demand a high strike rate to turn a profit.
The only meaningful question about strike rate is: does your rate beat the break-even rate that the odds you took actually demanded? Everything else is noise.
Strike rate matters most as a tool for self-assessment. It forces you to measure your selection accuracy and compare it head-on with the prices you took. The comparison reveals whether you found value or simply chased odds that were too short to carry your win rate.
How Strike Rate Is Calculated
Strike rate is simply wins divided by total bets, expressed as a percentage. If you have placed 120 bets and 47 won, your strike rate is 47 ÷ 120 × 100 = 39.2%. The calculation is straightforward and is the foundation of every other measure you might calculate about your record.
Break-even strike rate is equally simple: one divided by the decimal odds. At 2.00, the break-even rate is 1 ÷ 2.00 = 50.0%. At 3.00, it is 1 ÷ 3.00 = 33.3%. At 1.50, it is 1 ÷ 1.50 = 66.7%. These break-even rates are the thresholds where the odds and your strike rate combine to neither profit nor lose. Above the break-even rate, you profit; below it, you lose.
The power of this pairing is that it immediately shows whether your strike rate is any good at the odds you took. A 39.2% strike rate is losing at 2.00 (which needs 50%), break-even at around 2.55 (which needs 39.2%), and comfortably profitable at 3.00 (which needs 33.3%).
What the Calculator Shows You
Enter your wins and total bets, and the calculator returns your strike rate as a percentage. Enter the decimal odds you bet at, and it returns the break-even rate those odds demand. The calculator then shows you instantly whether you are above or below break-even at that price. This is the entire conversation: is your strike rate higher or lower than the break-even rate the odds required?
You can also check what happens if you bet at different odds. If your strike rate is 39.2%, you could enter 2.00 to see that you are below break-even, then enter 3.00 to see that you are above. This teaches the critical lesson: raising the odds you bet at lowers the break-even rate they demand, and your fixed strike rate can move from losing to profitable without any change in your selection skill.
Worked Example
Consider a record of 47 winners from 120 bets placed. The strike rate is 47 ÷ 120 = 39.2%. At face value, that is a solid record. But the meaning depends entirely on the odds. At 2.00, the break-even rate is 50.0%, so 39.2% is losing. At 2.50, the break-even rate is 40.0%, so 39.2% is almost at break-even, still just short. At 3.00, the break-even rate is 33.3%, so 39.2% is comfortably profitable — a five-point cushion.
The worked example includes a telling note: 39.2% is losing at 2.00, break-even at around 2.55, and comfortably profitable at 3.00. The same strike rate, the same 47 winners from 120 bets, the same selection skill — but completely different financial outcomes depending on what odds you took.
This is why quoting a strike rate without the odds is close to useless for any serious assessment. The raw percentage is almost meaningless in isolation. A bettor must always state what odds they achieved that rate at, or the figure communicates nothing about whether they made or lost money. Two bettors might both report a 39.2% strike rate from the same volume of 120 bets, but one could be profitable if they bet at longer odds, and the other could be breaking even if they backed shorter prices.
The Strike Rate Each Price Needs Just to Break Even
Every decimal price has a break-even strike rate attached to it. The table shows how different odds set different break-even thresholds, and how a fixed strike rate of 39.2% fares at each.
| Decimal odds | Break-even strike rate | Is 39.2% enough? |
|---|---|---|
| 1.50 | 66.7% | No |
| 2.00 | 50.0% | No |
| 2.50 | 40.0% | Almost |
| 3.00 | 33.3% | Yes |
| 4.00 | 25.0% | Yes |
The pattern is clear: longer odds demand lower strike rates to break even. At 1.50, you need 66.7%. At 2.00, you need 50.0%. At 3.00, you need only 33.3%. Short-priced favourites need a very high win rate; long-shot odds need only a modest one. This is why chasing higher strike rates by backing shorter odds usually destroys value — the break-even rate rises faster than you can improve your selection.
Why Strike Rate Alone Tells You Nothing
Three different betting histories illustrate why strike rate without odds is meaningless.
| Strike rate | Average odds | Outcome |
|---|---|---|
| 70% | 1.20 | Losing |
| 50% | 2.00 | Break-even |
| 39.2% | 3.00 | Profitable |
A 50% strike rate is bang-on break-even at 2.00, which needs exactly 50%. A 39.2% strike rate sounds mediocre but is actually profitable at 3.00, which needs only 33.3%. The same strike rate at 1.50 would be losing, since 1.50 requires 66.7% to break even.
This table teaches the core lesson: strike rate and odds are inseparable. Comparing two bettors’ strike rates without knowing their average odds is like comparing two runners’ times without knowing the distance. The same strike rate can represent a losing position at one set of odds and a winning position at another. Context is everything.
Why Voids and Partial Settlements Matter
A strike rate quoted without context is open to abuse, and it is one of the most common ways a betting record is made to look better than it is. Two things distort it: void bets and partially settled bets. A void is a cancelled or postponed match that is removed from settlement. If you count a void as a loss, you drag your strike rate down as though you had actually lost money. You should exclude voids from both the wins count and the total bets count.
Each-way bets and partially settled bets (bets where you collect something but not the full return) do not fall neatly into win or lose. Decide how you are counting those before comparing your strike rate from one month to the next. Inconsistent counting will make your record look artificially better or worse.
When Strike Rate Matters
Strike rate alone tells you very little, but paired with odds, it becomes useful. The most important use is checking whether your strike rate at the odds you actually took is enough to turn a profit. If you beat the break-even rate, you are profitable. If you fall short, you are losing.
Strike rate also helps you audit your betting decisions. If you know your overall strike rate is 39.2%, you can then filter by betting category — perhaps singles versus system bets, or different leagues — to see which parts of your portfolio are working and which are dragging down the total. The pattern that emerges often shows that your strength lies at longer odds, where 39.2% easily clears the break-even bar, while your shorter-odds bets are thin on value. This kind of breakdown teaches you where your actual edge lies.
Common Mistakes
Many bettors quote a strike rate without saying what odds it was achieved at, which makes the figure almost meaningless. Others count void bets as losses, which understates the rate and makes a record look worse than it is. Some chase a higher strike rate by backing shorter and shorter prices, which usually lowers profit even as the rate climbs. Finally, many compare strike rates across bet types that sit at completely different odds, such as singles versus systems, which is like comparing runners from different races.
Strike Rate Against the Other Record Measures
Strike rate, ROI, and CLV each measure a different aspect of a betting record.
| Measure | What it captures | Blind spot |
|---|---|---|
| Strike rate | How often you win | Ignores the price |
| ROI | Profit per euro staked | Needs a large sample |
| CLV | Whether you beat the close | Says nothing about profit |

Strike rate = Wins / Total bets, as a percentage.
Break-even strike rate at a given price = 1 / decimal odds.
You profit when your strike rate is above the break-even rate for the odds you take.
Frequently Asked Questions
How do I calculate strike rate?
Divide wins by total bets and multiply by 100. Forty-seven winners from 120 bets is a 39.2% strike rate.
What is a good strike rate?
It depends entirely on your odds. At 2.00 you need above 50%; at 3.00 above 33.3%. A 39.2% rate is losing at 2.00 and profitable at 3.00.
What is the break-even strike rate?
One divided by the decimal odds. At 2.50 that is 40.0%, so you need to win more than four bets in ten to profit.
Should void bets count?
No. Exclude them from both the wins and the total, otherwise they drag the rate down as though they were losses.
