Getting ready for Halloween isn't cheap.

Many Americans are spending more money on Halloween this year than last, according to an annual National Retail Federation report.

Here's a look at the numbers behind Halloween:

$8.4 billion will be spent on Halloween this year: According to the National Retail Federation (NRF), U.S. consumers will spend an average of $82.93, up from $73.34 last year.

$3.1 billion will be spent on costumes: Americans want to dress to impress, according to the national retail report. And while Americans are spending a lot of money on costumes, some are more expensive than others.

$2.5 billion will be spent on candy, according to the NRF: But your sweet tooth may cost you more this year. The price of candy and chewing gum has been on the rise since 1998 (even greater than the rate of inflation), according to the Bureau of Labor Statistics.

171 million Americans plan to partake in Halloween festivities.

At Woods of Terror in Greensboro, the revenue goes right back into all the decor, costumes and make up.

There are more than 100 actors this year - all have to go through extensive training to learn how to "scare" people.

It takes about 2 hours to get all the characters in costume and make-up.

Woods of Terror is open until the first weekend of November - click here for more information.
