OK — have been messing about with this thing for something like four months now and it’s basically bookmarked at this point, so thought I’d chuck my thoughts in since a mate asked me the other day. Am UK based, generally bet football and racing, a fiver here and there, for context.

How I found it was genuinely pretty stupid — I couldn’t ever figure out what an each way return actually came to when the place terms changed. Basically I’d guess and then be surprised. Now punch the numbers in first, every time, even a straight one-selection punt.

The single bet calculator tool is the bit I open most — type in your stake, the odds and it spits out returns instantly, either odds format. It also handles the multiples — acca and treble returns, lucky 15 and lucky 63, a yankee, which is where most people I know mess it up. If you want a look, it’s here [url=https://singlebettingcalculator.uk/bet-calculator/matched-betting]how is matched betting calculated[/url] and it’s free with no account nonsense.

The thing that really changed how I bet was the geekier bits. They’ve got an odds-to-probability converter that shows how much the bookie’s taking, and a kelly staking tool — I stick to fractional kelly as the full version is a quick route to a dead bankroll. Dutching calculator is handy too for when I’m splitting a race.

It’s not perfect mind. Its design feels pretty plain — not much frills, looks like it was built by someone who cares more about maths than colours. On mobile it’s fine although the acca grid make you pinch and zoom. Also there’s no proper app, it’s browser only — doesn’t bother me just flagging it.

So yeah. Free, no ads shoved in your face, works. Anyone who still works out returns on a calculator app, have a look — saves me a fair few arguments with the bookie.
