Sales tax is a consumption tax imposed by governments on the sale of goods and services. It is typically calculated as a percentage of the purchase price and is added at the point of sale. Understanding how to calculate sales tax is crucial for both consumers and businesses to accurately determine costs and manage finances.
How Sales Tax is Calculated
The basic formula for calculating sales tax is straightforward:
Consumers: Quickly estimate the final price of items before making a purchase, especially when shopping online or in areas with different tax rates.
Businesses: Ensure accurate pricing, track revenue, and prepare for sales tax filings. This is essential for inventory management and point-of-sale systems.
Budgeting: Help individuals and families budget for purchases, factoring in the added cost of sales tax.
E-commerce: Online retailers use sales tax calculators to apply the correct tax to orders based on the customer's shipping address, complying with various state and local tax laws.

}
var taxAmount = price * (taxRate / 100);
var totalCost = price + taxAmount;
resultDisplay.textContent = "$" + taxAmount.toFixed(2);
totalCostDisplay.textContent = "Total Cost: $" + totalCost.toFixed(2);
