single bet calculat

OK — have been messing about with this thing for something like a few months now and it's stuck on my phone, reckon I'd write something up since someone asked me a few days back. I'm in the UK, mostly bet football and racing, small stakes, for context.
 
The reason I started using it was honestly a bit daft — I couldn't ever get my head round what an e/w payout would be once you get five places instead of three. I'd just guess and moan when the payout landed. Now I punch the numbers in before I place anything, even a straight one-selection punt.
 
Their single bet calculator is the part I open most — you drop in the price and your stake and it shows profit and total return instantly, either odds format. There's also the fiddly ones — acca and treble maths, lucky 15s, yankees, which is where most people I know got it wrong. Have a go yourself, it lives at <a href=https://free-bet-calc.uk/bet-calculator/trixie>trixie free bet calculator</a> and there's no login wall, which I appreciated.
 
What genuinely shifted things for me were the geekier bits. The implied probability calculator and it makes obvious how much the bookie's taking, and a kelly staking calculator — I stick to fractional kelly because full kelly is terrifying. Dutching calculator gets used a fair bit for when I'm covering two or three runners.
 
Not all sunshine though. Its layout looks a bit basic — zero flash, looks like it was built by someone who cares more about maths than colours. On my phone it works but the lucky 63 breakdown make you pinch and zoom. There's no app, just the site — slight shame just flagging it.
 
Right, that's me. Free, no ads shoved in your face, does what it says. If you still works out returns on a calculator app, try it — it's saved me a fair few "wait, that's it?" moments.
