OK — have been messing about with this thing for something like a few months now and it’s basically bookmarked at this point, so thought I’d write something up since a lad on another thread asked me the other day. I’m in the UK, mainly do football and horses, small stakes, just so you know where I’m coming from.

The reason I started using it was actually pretty stupid — I couldn’t ever work out what an e/w return actually was with 1/5 odds a place. Basically I’d eyeball it and then be surprised. Now I punch the numbers in first, every time, even a straight one-selection punt.

Their single bet calculator is the one I’m on daily — you put in stake and odds and it spits out profit and total return straight away, fractions or decimals. There’s also the multiples — doubles and trebles returns, a lucky 15, patents and yankees, and that’s where most people I know mess it up. Have a go yourself, it’s over at [url=https://singlebettingcalculator.uk/bet-calculator/dutch]free dutching calculator[/url] and it’s free with no account nonsense.

What actually made a difference were the geekier bits. They’ve got an probability thing and it makes obvious what margin’s baked in, and a kelly criterion calculator — I use half kelly as the full version is terrifying. The dutch tool gets used a fair bit if I’m spreading across selections.

Couple of gripes. The interface feels a bit basic — no frills, which honestly I don’t mind but some will. On my phone it’s usable although the lucky 63 breakdown make you pinch and zoom. Also there’s no app, it’s browser only — fine by me just flagging it.

So yeah. Free, barely any ads, does the job. If anyone still adds it up in their head, give it a go — saved me plenty of “wait, that’s it?” moments.
