Hello and welcome to our guide to using our lucky 15 calculator. In this guide, we'll show you what a lucky 15 bet is and why you’ll need a calculator to go with it.
A lucky 15 bet can be a difficult bet to put together and it can be even tougher to get right as well. All you need is the right calculator to give you a better shot at success. Take a look at the rest of our guide to see why you need our lucky 15 calculator free tool.
Before we can get to what our lucky 15 calculator is and how it benefits you, we first need to touch on what a lucky 15 bet actually is. If you have only recently come to grips with the concept, it's not a bad idea to brush up on what it is. Well, put simply, a lucky 15 bet is just 15 different bets that are all of equal value, placed on selections in 4 different events. The combination of your 15 bets needs to be very specific as it needs to include the following: our singles, six doubles, four trebles and one four-fold accumulator. As you can see, there are quite a few moving parts with this kind of betting strategy. Even your most experienced online sports betting fans can struggle with a betting type that is this complex. That is precisely why you would need something like our lucky 15 calculator.
The basic idea of the calculator:
It doesn’t take much for you to see that a lucky 15 bet is quite a complex thing to stay on top of. I mean we are in this business and even our heads get a little dizzy looking at it. This is exactly why we put our lucky 15 calculator together. Our lucky 15 calculator will help you figure out what your potential payout is for your bet. Not only that but, like an
odds calculator, it can help you see what sportsbooks are offering you the best odds, it can change the type of odds you are using and convert them for you in a swift fashion and it can even give you your total outlay and your total returns as well. This is the basic idea of the lucky 15 calculator but we have a lot more to get to in terms of how it serves you with this type of betting strategy.

Why you need a lucky 15 calculator - give yourself an edge
While a lucky 15 can certainly be tricky to navigate, especially for first-timers, that does not mean there aren’t experienced horse racing bettors who can’t do it themselves. That is all good and well, and honestly quite impressive, but that still leaves room for human error.
Cut out any mistakes
Even if you feel like you can complete your lucky 15 bet by yourself, there is always the chance that you miscalculate or miss a step somewhere. This is one of the biggest reasons that even the most experienced horse racing punters use our lucky 15 calculator. Once you enter the odds you want to use from all of your selections into our lucky 15 calculator, it does all the work for you. There is no chance of you undervaluing your bet (or overvaluing for that matter), no chance of misunderstanding the total amount of your wager or anything else that you could possibly miss. Just like our trixie calculator, you can rely on our lucky 15 calculator to do all the work seamlessly for you to make sure you fully appreciate what you are betting on and what your potential outlay, returns and profits are.

Why you need to use a lucky 15 calculator - smooth out your rough edges
You can see pretty clearly that there are some major positives to using our lucky 15 calculator. With that said, is the lucky 15 calculator that we provide for you only really useful for helping you avoid silly errors?
Knowing where the value really lies
The answer to that is a resounding no. One of the best parts of our lucky 15 calculator is that it can help you formulate the perfect bet with the odds that you have at your disposal. What we mean by this, is that you can shop around on a host of other online sportsbooks to see what odds they are offering you on the same race and jockeys. From there, you can play around with our lucky 15 calculator to see which sportsbooks are actually giving you the chance for a value bet. All it takes is for you to play around for a while until you see what sportsbook you should be using for a specific race.
Top tips for using a lucky 15 calculator for the first time - what you should keep in mind
We couldn’t let you leave us without giving you some top tips for using our lucky 15 calculator. At the end of the day, you will get to know the lucky 15 calculator we offer you from the time you spend using it. Here are a couple of tips to get you started off on the right foot:
Keep it as simple as possible at first:
While the very nature of a lucky 15 bet is that it is quite complex, there are ways for you to keep it a little more straightforward. Try to make sure that you aren’t placing your first couple of bets on outlandish odds. Furthermore, try to keep the accumulator part of your lucky 15 bet simple as well as this is where you will most likely falter.
Don’t let the returns blind you:
While we recommend that you play around with our lucky 15 calculator like you would with our lucky 31 calculator, we don’t want you to be drawn in by the returns alone. Seeing the number in front of you can sometimes lead you to go for a bet that may be a bit audacious. Keep things simple, keep things well thought out and don’t let the
potential
rewards cloud your betting judgement.
Check the figures and then check them again
There is going to be a hefty amount of information that you need to enter into our lucky 15 bet calculator which is all the more reason for you to be extra careful when you do so. Once you have entered the odds and everything else that is required in the blank fields of our lucky 15 calculator, make sure you double check the figures again. All it takes is a minor error in the figures and betting types for your entire bet to be thrown off course.
