Right — been on this thing for about six months now and it’s basically bookmarked at this point, reckon I’d say something since a mate asked me a few days back. Am UK based, generally do football and horses, nothing mad, just so you know where I’m coming from.

How I found it was honestly embarrassing — I could never work out what an e/w payout actually was when the place terms changed. I used to just wing it and moan when the payout landed. Now punch the numbers in first, every time, even a simple single bet.

Their single bet calculator is the one I open most — type in your stake, the odds and it spits out the return with no faffing, fractions or decimals. There’s also the bigger stuff — trebles maths, a lucky 15, yankees, honestly that’s where most people I know lose track. If you fancy a poke about, it’s over at [url=https://singlebettingcalculator.uk/bet-calculator/kelly-criterion]kelly criterion formula[/url] — free, no signup.

What really shifted things for me is the nerdier tools. They’ve got an probability converter that shows what margin’s baked in, and there’s the kelly criterion calculator — I use half kelly since full stakes are a quick route to a dead bankroll. The dutch tool is decent for when I’m covering two or three runners.

Couple of gripes. Its layout looks pretty plain — not much polish, it’s clearly function over form. On my phone it’s fine though the lucky 63 breakdown are a squeeze. Also there’s no proper app, it’s browser only — doesn’t bother me just flagging it.

So yeah. Costs nowt, not plastered in adverts, works. Anyone who still works out returns on a calculator app, have a look — it’s saved me a fair few arguments with the bookie.
