Input the local sales tax rate applicable in your area (e.g., 8.25 for 8.25%). - Click “Calculate”

💡 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.
