For many, the dream of taking potions classes and playing Quidditch on the grounds of the Hogwarts School of Witchcraft and Wizardry hasn't faded since the first book was released in 1997. But over the years, there's been some speculation about how difficult it would be to attend the school -- partly because of the magical requirement and partly because of the cost.

Now, J.K. Rowling, the author of the world-famous "Harry Potter" series, has revealed the price of tuition to attend Hogwarts. The billionaire author responded to a tweet Friday about how high the cost of attendance would be at the school.

News outlet Mic estimated last year that Hogwarts would cost a total of $43,000 per year. It turns out that was a bit off.

There you have it: Tuition at Hogwarts is free, aside from the cost of books and supplies, such as cauldrons, scales and -- of course -- your wand. Mic estimated the cost of these items at around $1,031, using figures from the books and the website Pottermore, an extended universe fan site and interactive book experience run by Rowling.

This explains a lot, considering the Weasley family -- regularly cited as poor throughout the series -- managed to send seven children to the wizarding school. Good on the Ministry of Magic for keeping a magical education affordable. Otherwise, the next arrival in the "Harry Potter" cinematic universe could have been titled "Harry Potter and the Student Loan Debt," rather than "Fantastic Beasts and Where to Find Them."
