Here I have made a Golf Lesson Price Calculator.
Here you have the chance to calculate your future golf lesson cost. This is only a comparison table to see if your new golf instructor maybe take to much money for his job.
But aware: Some real good Golf Coaches took a lot of money because the people will pay them this money. So use this calculator only as a benchmark.
Maybe you find a real cheap golf course or golf academy. That don't mean that their service is crap. If they have enough people who pay them, they can give you as a customer a discount.
Personal lessons aren't a good choice if you are a real beginner of golf. Take a first lesson to learn the biggest things you need to take care of and starting with a group to learn golfing.
If your skills getting better and you think you can't reach the next step than you have the choice to take personal golf lessons to increase your performance.
