How to calculate the total cost including sales tax?

The total cost of an item including sales tax can be calculated using the following formula:

Total Tax:

§§ \text{Total Tax} = \left( \frac{\text{Item Cost} \times \text{Tax Rate}}{100} \right) \times \text{Quantity} §§

where:

  • § \text{Total Tax} § — the total amount of sales tax
  • § \text{Item Cost} § — the price of a single item
  • § \text{Tax Rate} § — the sales tax percentage
  • § \text{Quantity} § — the number of items purchased

Total Cost:

§§ \text{Total Cost} = \left( \text{Item Cost} + \text{Total Tax} \right) \times \text{Quantity} §§

This formula calculates the total cost by adding the item cost and the total tax, then multiplying by the quantity of items.

Example:

  • Item Cost (§ \text{Item Cost} §): $100
  • Sales Tax Rate (§ \text{Tax Rate} §): 5%
  • Quantity (§ \text{Quantity} §): 2

Calculating Total Tax:

§§ \text{Total Tax} = \left( \frac{100 \times 5}{100} \right) \times 2 = 10 §§

Calculating Total Cost:

§§ \text{Total Cost} = (100 + 10) \times 2 = 220 §§
