Knowing the total cost after tax helps ensure accurate budgeting and financial planning.
Smart Strategy
Always factor in taxes and any additional fees to avoid surprises during the checkout process.
Product Price: $${productPrice.toFixed(2)}
Quantity: ${quantity}
Tax Rate: ${(taxRate * 100).toFixed(1)}%
