Place Odds Calculator

---

Adjust the number of runners and places in the top 2 boxes. Enter digital odds in the left hand 'win odds' column. The book they make will be scaled up or down to make it a 100% book.

Note that the odds are in digital notation, where 2.0 means "evens", 3.0 means "2/1", 1.5 means "1/2" and so on.

Note also that the place odds shown are likely to be shorter than true odds on short-priced runners and longer than true odds on outsiders. In other words, favoured horses place far less often than the odds given by this calculator would indicate. I believe one cause of this is that often if an odds-on favourite doesn't win it's because it has fallen, not because it has been outrun. Odds-on favourites have a tendency to either win or come nowhere. This calculator doesn't (yet) take this into account.

Finally, note that this calculator comes with absolutely no warranty. The calculations are quite possibly all wrong. If you find it useful, feel free to use it. If you want to copy the source code and improve it, please feel free to do so.
