How to Calculate Horse Racing Strike Rate

What it means

Strike rate is the number of winning selections divided by total settled selections, multiplied by 100.

Strike rate is wins divided by settled selections, but it says nothing alone about price or profit.

A worked example

If 18 of 60 settled win bets succeed, strike rate is 30%.

Ten winners from 50 bets gives a 20% strike rate. At average winning odds below the required break-even level, that can still lose money.

How to keep the assessment honest

Write down the rule before betting, keep all settled results including losers, and use actual stakes and returns. Separate paper tests from real-money results.

Common mistakes and limitations

Strike rate alone says nothing about profit: odds and stake size also matter.

Short samples are volatile. High returns in a few races should not be extrapolated into a reliable income expectation.

Strike rate is not profitability

If 12 of 60 win bets win, strike rate = 12 ÷ 60 × 100 = 20%. At average decimal odds of 3.0, a flat £1 stake would return £36 from £60 staked, producing −40% ROI despite those 12 winners.

Practical checks and limitations

Conversely, a low strike rate can be profitable at sufficiently long odds. Record average price, turnover and returns alongside the win percentage.
