So — have been messing about with this thing for something like four months now and it’s basically bookmarked at this point, so figured I’d say something since someone asked me last week. I’m based in the UK, generally bet football and racing, a fiver here and there, so take it how you like.

How I found it was genuinely embarrassing — I never could work out what an e/w return actually came to with 1/5 odds a place. Basically I’d guess and get a shock. Now type the odds in first, every time, even a straight one-selection punt.

Their single bet calculator is the bit I open most — you put in your stake, the odds and it spits out the return instantly, fractions or decimals. Same tool covers the fiddly ones — acca and treble maths, lucky 15s, a yankee, honestly that’s where I always mess it up. If you want a look, it’s over at [url=https://free-bet-calc.uk/bet-calculator/lucky-15]lucky 15 bet[/url] — free, no signup.

What really shifted things for me was the geekier bits. The odds-to-probability calculator and it makes obvious the overround, plus a kelly criterion calculator — I run quarter kelly because full kelly is a quick route to a dead bankroll. The dutch tool is decent for when I’m splitting a race.

Couple of gripes. The design is a bit basic — zero frills, it’s clearly function over form. On mobile it’s fine but the lucky 63 breakdown need a bit of scrolling. There’s no proper app, it’s a website and that’s it — fine by me but worth saying.

So yeah. Free, no ads shoved in your face, works. If anyone still works out returns on a calculator app, give it a go — saved me a fair few “wait, that’s it?” moments.
