💡 Example: Calculating a Diamond Ring Purchase

Let’s say you’re planning to purchase a 1.50-carat diamond with the following details:

  • Price Per Carat: $5,200
  • Ring Setting Cost: $1,100
  • Sales Tax Rate: 7.5%

Calculation:

  • Diamond Cost = 1.5 × $5,200 = $7,800
  • Subtotal (Diamond + Setting) = $7,800 + $1,100 = $8,900
  • Tax = 7.5% of $8,900 = $667.50
  • Total Cost = $8,900 + $667.50 = $9,567.50

With our calculator, you would instantly see a total cost of $9,567.50.
