Bet Builder Calculator

Estimate the combined odds of a bet builder or same-race multi.

- Combined odds
- Est. return
- Est. profit

How to use the Bet Builder Calculator

  • Enter your stake and the odds of each leg.
  • The calculator multiplies the legs together, as an accumulator would.
  • Treat the result as an upper bound: bookmakers price bet builders shorter, because legs in the same race or match are linked.
