So — have been messing about with this thing for maybe four months now and it’s basically bookmarked at this point, so figured I’d write something up since a lad on another thread asked me last week. I’m in the UK, generally do football and horses, small stakes, so take it how you like.

The reason I started using it was genuinely embarrassing — I could never get my head round what an each way return would be when the place terms changed. I’d just guess and get a shock. Now I stick my stake in before every slip, even a simple single bet.

The single bet calculator tool is the one I use most — type in stake and odds and it spits out profit and total return with no faffing, either odds format. It also handles the bigger stuff — doubles and trebles maths, a lucky 15, a yankee, and that’s where I’d always lose track. Have a go yourself, it’s here [url=https://single-calculator.com/bet-calculator/accumulator]acca odds[/url] and it’s free with no account nonsense.

What really changed how I bet was the more serious tools. They’ve got an odds-to-probability calculator that shows the overround, and a kelly staking calculator — I stick to fractional kelly since full stakes are a quick route to a dead bankroll. The dutch tool gets used a fair bit when I’m spreading across selections.

It’s not perfect mind. Its design looks a bit basic — no flash, looks like it was built by someone who cares more about maths than colours. Phone-wise it works though the acca grid are a squeeze. Also there’s no app, it’s a website and that’s it — fine by me but worth saying.

Right, that’s me. Free, no ads shoved in your face, works. If you honestly works out returns on a calculator app, give it a go — saves me plenty of arguments with the bookie.
