If you pay or receive child support in Tennessee and are curious about child support calculations, check out this free website: tnchildsupportcalculator.com
(You'll have to copy and paste as this forum is censoring my links)

It uses the same formula mandated by the state of Tennessee and has all of the same features as the official calculator, but it works in most browsers and even works on Mobile devices, like iPhone, iPad, and Android devices.

Check it out. Great for educating yourself and your peers.
