The Smart Tip Calculator

Never worry about tipping again. No matter what country you're in, Gratzi has your back. Our research team has done the heavy lifting and pre programmed over 100 individual tipping trends. Since gratuity is based on how much people generally give, Gratzi can help pull these trends together to make knowing how much to tip so much easier.
