Everyone has heard horror stories about companies selling a coupon on one of those group buy websites, and then having a huge stream of unprofitable business, resulting in a massive loss. On the flip side, many companies have had great success from coupon campaigns.

We’ve put together a calculator (opens in new window) to try and assist anyone considering a group coupon campaign. Feel free to play around with its parameters to get a feel for when a coupon would be profitable – or not.

There’s also a new tools page that links to this calculator, as well as the previous CPC/PPC one. We’re open to suggestions regarding other tools that may be useful to businesses.
