single bet calculator

OK — been on this thing for about four months now and it's stuck on my phone, so figured I'd say something since someone asked me the other day. Am UK based, mostly do football and horses, nothing mad, just so you know where I'm coming from.

The reason I started using it was actually a bit daft — I never could work out what an e/w payout actually came to once you get five places instead of three. I used to just guess and get a shock. Now I punch the numbers in first, every time, even a simple single bet.

The single bet calculator is the one I open most — you drop in your stake, the odds and it spits out returns with no faffing, fractional or decimal, doesn't matter. Same tool covers the multiples — acca and treble maths, lucky 15 and lucky 63, a yankee, honestly that's where I always got it wrong. Have a go yourself, it's here how to work out a lucky 63 — free, no signup.

What actually shifted things for me were the more serious bits. They've got an probability converter and it makes obvious how much the bookie's taking, and a kelly staking calculator — I use half kelly because full kelly is a quick route to a dead bankroll. Dutching calculator is decent when I'm covering two or three runners.

Not all sunshine though. Its interface looks pretty plain — not much frills, looks like it was built by someone who cares more about maths than colours. On my phone it's fine though the acca grid are a squeeze. Also there's nothing on the app store, it's browser only — slight shame but worth saying.

So yeah. Free, not plastered in adverts, does what it says. If you even now does the maths on paper, give it a go — saves me a fair few "wait, that's it?" moments.
