What is a Point of Sale (POS) Calculator?

A Point of Sale (POS) Calculator is used to determine the total amount due for a purchase, including the price of the items, applicable taxes, and any additional fees or charges. It helps in ensuring accurate billing and financial transactions.

Example Calculation

Consider an example where:

Price of Item(s) Purchased (P): $100
Tax Rate (T): 0.08 (8%)
Additional Fees or Charges (F): $5

Using the formula to calculate the Total Amount Due:

\[ T = 100 + (100 \cdot 0.08) + 5 = 113 \text{ dollars} \]

This means that the total amount due for this example is $113.
