Key takeaways

The bet calculator, each-way single calculator, Rule 4 calculator and dead heat calculator work out returns before or after a race.
The odds converter switches between fractional odds, decimal odds and implied probability.
The draw bias checker shows how each stall has done at a course, distance and going.
Every tool is free, needs no account and has no bookmaker links.

Which calculator do I need?

Use the bet calculator or each-way single calculator for most bets, the Rule 4 calculator when a horse is withdrawn late, and the dead heat calculator when two horses share a place.

Each tool shows how the return is worked out, so you can check a settlement line by line. The draw bias checker is for before the race: it shows whether low or high stalls have done better at that course, distance and going.
