The tippingCalculator is arguably the most sophisticated, intuitive, flexible, and easiest app for calculating gratuity. It's just as simple as 1-2-3. Step one, enter the subtotal or the total bill amount. Step two, enter the tax percentile or tax amount. Step three, enter the tip percentile or tip amount and the tippingCalculator will do the rest. Splitting the bill? Just slide the split slider to the number of people sharing the bill.

Features:
- Shows break-down in detail
- Has flexibility to override fields
- Calculates in real time as fields are entered
- Splits bill for up to 100 people
- Saves the last value of tax and tip percentile entered
- Has ability to round the grand total

Note:
- The tippingCalculator is designed for use in the United State of America or those countries that have similar currency format.
- Tip amount is calculated before tax. And of course, you could always override it by simply entering the tip amount field you want to give.
