Not all children are fond of pulling out a loose tooth, but most are usually excited about being able to leave the tooth under their pillow. According to a survey by Visa, they might have even more to be excited about. 

USA Today reported that the survey showed that the Tooth Fairy is leaving an average of $3 per tooth, which is up 15 percent from last year when the average was $2.60 per tooth.

"The Tooth Fairy may be the canary in the economic coal mine. She's showing signs of life by leaving 40 cents more per tooth this year," said Jason Alderman, Senior Director of Global Financial Education, Visa Inc. in a press release.

"This is not only good news for kids, but an ideal teachable moment for parents to engage their children in thinking about how to budget their windfall by saving a portion," Alderman added.

The survey also found:

• 3 percent of children receive less than a dollar, down from 7 percent last year.
• 30 percent of children receive exactly $1. Last year's survey showed that 29 percent of children received exactly $1.
• 13 percent of children receive between $2 to $4, down from 18 percent last year.
• 18 percent of children receive $5, the same amount as compared to last year.
• 8 percent of children receive more than $5, compared to 3 percent last year.

In addition to the release of the survey, Visa also announced the creation of a free mobile app and online calculator to help parents figure out how much money to leave beneath their children's pillows. The app and calculator use Visa's survey data and factors in demographics such as gender, age, home state, income and education levels to formulate how much money the Tooth Fairy is leaving in comparable households.

The app is available for iPhones and iPads at the iTunes Store, while the calculator is available at: www.PracticalMoneySkills.com/ToothFairy.
