Six calculators for stakes, returns and implied probability — odds conversion, each-way, lay and matched betting, dutching, accumulators and full cover bets with non-runners handled properly.

Common questions
What's the difference between fractional, decimal and American odds?
Fractional odds (5/2) show profit relative to stake. Decimal odds (3.50) show the total return including your stake. American odds use +250/−140 to say the same thing from either side of evens — all three describe one number, implied probability, which the odds converter puts side by side.
What does an acca bonus actually add?
A percentage uplift on winnings once a set number of legs win — typically 5% on four legs, rising with each extra leg. The accumulator calculator applies it after the combined odds, which is how most bookmakers do it.
What happens to a Lucky 15 with a non-runner?
A non-runner is treated as a winner at odds of 1/1 (evens) for any bet it's part of, so the remaining selections still count — the full cover bets calculator applies that rule automatically rather than voiding the whole bet.
