From Chewy Applications:
British Columbia Sales Tax Calculator is the fastest and most straight forward sales tax app on the App Store. Simply enter your value in one of three boxes, and the other values are calculated as you key in the numbers. BC Sales Tax Calculator is useful in three specific cases: 'Adding Sales Tax': When you know a price excluding sales tax, and you need to know how much tax will be added, and what the final value is including the tax. 'Removing Sales Tax': When you know the final price including sales tax, and you need to know the tax component, and the amount before the tax was included. 'Working backwards': When you only know the sales tax amount, and you need to know what the original price of the goods were, excluding and including tax. Why BC Sales Tax Calculator is great: Automatic Calculations Results are calculated and displayed as you key in the numbers. Copy and Paste Starting values can be paste into any field, and results can be copied and pasted into other apps. Quick Entry The large number-pad is quick and easy. Quick Reset Tap the clear button in any of the boxes to reset the calculation. Multi-purpose Enter a value in any of the three input fields, and the other two fields will be calculated from that.
