Right — have been messing about with this thing for something like five months now and it’s basically bookmarked at this point, reckon I’d write something up since a lad on another thread asked me last week. Am based in the UK, mainly bet football and racing, nothing mad, for context.

How I found it was genuinely embarrassing — I could never work out what an each way return would be when the place terms changed. I used to just eyeball it and get a shock. Now I punch the numbers in before I place anything, even the boring singles.

Their single bet calculator is the bit I use most — type in the price and your stake and it shows the return instantly, fractions or decimals. There’s also the bigger stuff — trebles maths, a lucky 15, yankees, and that’s where I always got it wrong. If you fancy a poke about, it lives at [url=https://freebet-calculator.com]single bets calculator[/url] and there’s no login wall, which I appreciated.

What genuinely changed how I bet was the more serious bits. The probability thing and it makes obvious how much the bookie’s taking, and there’s the kelly tool — I stick to fractional kelly as the full version is a quick route to a dead bankroll. Dutching calculator is decent for when I’m splitting a race.

Not all sunshine though. Its layout is pretty plain — not much flash, looks like it was built by someone who cares more about maths than colours. On my phone it’s fine though the lucky 63 breakdown are a squeeze. And nothing on the app store, it’s browser only — fine by me but you asked.

So yeah. Doesn’t cost anything, barely any ads, works. If anyone honestly does the maths on paper, have a look — saved me a load of dumb bets I’d have regretted.
