Frequently Asked Questions (FAQ)


Top Price Calculator


1. Enter or Modify Price


Simply touch the price amount displayed on the Price line and enter the before-sales-tax price. The other amounts including the applicable sales tax(es) and total price will automatically update as you enter the price.

You can edit the existing price by touching the Back button at the top right of the calculator keys. This will remove the last number (or decimal point) entered.

2. Include Sale/Discount in Calculation


If the item or service is on sale, simply touch the % or the dollar value on the Sale line and type in the sale percentage or discount amount. The other amounts, including the applicable sales tax(es) and total price, will automatically update as you update the sale value.

To calculate an additional (second) discount, start by entering the first discount/sale and then enter the additional discount percentage on the second Sale line.

3. Calculate Price For Multiple Items


You can calculate the total price of multiple items by using the + or x calculator keys while the Price or Total values are selected. Examples:

  • 49.99 x 6
  • 19.99 + 4.99

  • If more than one operation is entered, the previous operation will first be calculated before performing the new operation. For example, entering the equation  49.99 - 6  followed by  x 10  will be calculated as  (49.99 - 6) x 10.

    4. Activate/Deactivate Taxes


    Tap the ... icon to the right of the tax line(s) to display tax related options. These options allow you to exclude one or more taxes from your calculation. This is useful when the item you are purchasing is not taxable or otherwise excludes a particular tax normally applied to other products and services.

    5. Add Custom Tax


    Tap the ... icon to the right of the tax line(s) to display tax related options. Activate (switch on) an additional tax to display the new tax and then tap the new tax line's % to enter the desired percentage.

    6. Reverse Price Calculation


    If you already have the total price of an item or service and would like to determine the price before tax, simply touch the total price number displayed on the right side of the Total line and enter the after-sales-tax price. The other numbers including the sales tax(es) and before-sales-tax price will automatically update as you enter the total value.

    7. Calculate Tip


    To calculate a tip amount, first tap the yellow cup icon to display the tip calculator.

    To change the tip percentage, first select it by tapping it, and then enter a new percentage.

    To specify a tip amount (rather than a tip percentage), first select it by tapping it, and then enter a new amount. The matching tip percentage will be displayed.

    To specify the total bill amount, including the tip (rather than specifying a tip percentage or amount), first select the Grand total amount by tapping it, and then enter a new amount. The tip amount and percentage will automatically change as you enter a new Grand total amount.

    8. Split Bill


    Touch the icon at the right of the tip amount to access the Split Bill feature. A panel will be displayed at the bottom of the screen. Tap the plus or minus sign to specify the number of people with whom you are splitting the bill.
