So — have been messing about with this thing for about four months now and I keep coming back, so figured I’d say something since a lad on another thread asked me the other day. Am in the UK, generally stick to footie and the horses, nothing mad, just so you know where I’m coming from.

The reason I started using it was genuinely pretty stupid — I could never figure out what an ew return actually was with 1/5 odds a place. Basically I’d wing it and then be surprised. Now I punch the numbers in before every slip, even a simple single bet.

The single bet calculator tool is the part I’m on daily — you put in your stake, the odds and it shows returns straight away, fractional or decimal, doesn’t matter. It also handles the multiples — doubles and trebles maths, lucky 15 and lucky 63, yankees, which is where most people I know got it wrong. Have a go yourself, it’s here [url=https://singlebettingcalculator.uk/bet-calculator/implied-probability]implied probability[/url] and it’s free with no account nonsense.

What genuinely made a difference is the more serious bits. They’ve got an probability calculator that shows the overround, and there’s the kelly calculator — I stick to fractional kelly as the full version is a quick route to a dead bankroll. The dutch tool gets used a fair bit for when I’m covering two or three runners.

Couple of gripes. Its interface looks pretty plain — no frills, looks like it was built by someone who cares more about maths than colours. On mobile it’s fine although the bigger tables need a bit of scrolling. There’s no app, it’s a website and that’s it — fine by me but worth saying.

Anyway. Doesn’t cost anything, no ads shoved in your face, does the job. Anyone who even now works out returns on a calculator app, try it — it’s saved me plenty of arguments with the bookie.
