Right — have been messing about with this thing for about five months now and I keep coming back, so figured I’d say something since a mate asked me last week. Am based in the UK, generally bet football and racing, nothing mad, so take it how you like.

How I found it was honestly embarrassing — I could never work out what an ew payout actually was with 1/5 odds a place. I used to just eyeball it and moan when the payout landed. Now punch the numbers in first, every time, even a straight one-selection punt.

The single bet calculator tool is the one I’m on daily — you drop in stake and odds and it spits out the return instantly, fractions or decimals. Same tool covers the multiples — doubles and trebles maths, lucky 15 and lucky 63, patents and yankees, which is where most people I know got it wrong. Have a go yourself, it’s over at [url=https://singlebettingcalculator.uk/bet-calculator/lucky-15]free lucky 15 bet calculator[/url] and there’s no login wall, which I appreciated.

The thing that actually shifted things for me was the geekier bits. The odds-to-probability thing and it makes obvious the overround, plus a kelly staking calculator — I run quarter kelly since full stakes are far too aggressive. Dutching calculator gets used a fair bit when I’m covering two or three runners.

Couple of gripes. The layout feels very functional, let’s say — no flash, looks like it was built by someone who cares more about maths than colours. On my phone it works but the bigger tables are a squeeze. There’s no proper app, just the site — fine by me but you asked.

So yeah. Costs nowt, not plastered in adverts, works. Anyone who still adds it up in their head, have a look — it’s saved me a fair few “wait, that’s it?” moments.
