Limitations
Local Tax Variations
The calculator uses a single tax rate input. In reality, many jurisdictions have additional local taxes that may apply.
Tax-Exempt Items
Some items may be tax-exempt or have reduced rates (like groceries or medications) which this calculator doesn't account for.
Rounding Rules
Different jurisdictions have different rounding rules for tax amounts (up, down, or to nearest). The calculator uses standard rounding.
Sales Tax Formulas
Below are the formulas used for sales tax calculations.
1. Basic Sales Tax Calculations
- Tax Amount = Before Tax Price × (Tax Rate / 100)
- After Tax Price = Before Tax Price + Tax Amount
- Combined Formula: After Tax Price = Before Tax Price × (1 + Tax Rate / 100)
Example:
Calculate total for $100 at 6.5% tax:
Tax Amount = $100 × 0.065 = $6.50
After Tax Price = $100 + $6.50 = $106.50
Or directly: $100 × 1.065 = $106.50
2. Reverse Calculations
When you need to find the before-tax price or the tax rate from the total.
- Before Tax Price = After Tax Price / (1 + Tax Rate / 100)
- Tax Rate = [(After Tax Price - Before Tax Price) / Before Tax Price] × 100
Examples:
Find original price of $106.50 at 6.5% tax:
Before Tax Price = $106.50 / 1.065 = $100.00
Find tax rate when $100 becomes $106.50:
Tax Rate = [($106.50 - $100) / $100] × 100 = 6.5%
