The Mathematical Formula Behind the GST Calculator
Our calculator uses the standard GST formulas used by tax authorities worldwide. Here's the math:
Exclusive GST (Add Tax):
$$ \text{GST Amount} = \text{Amount} \times \frac{\text{GST Rate}}{100} $$$$ \text{Final Amount} = \text{Amount} + \text{GST Amount} $$
Inclusive GST (Remove Tax):
$$ \text{Original Amount} = \frac{\text{Amount}}{1 + \frac{\text{GST Rate}}{100}} $$$$ \text{GST Amount} = \text{Amount} - \text{Original Amount} $$
GST Share:
$$ \text{GST Share} = \frac{\text{GST Amount}}{\text{Final Amount}} \times 100 $$Understanding each variable:
- Amount: The base amount (exclusive) or total amount (inclusive).
- GST Rate: The applicable tax rate (e.g., 18%).
- GST Amount: The tax amount calculated.
- Original Amount: The amount before tax (for inclusive calculations).
- Final Amount: The total amount including tax (for exclusive calculations).
- GST Share: The percentage of the final amount that is tax.
The formulas are straightforward but essential for accurate tax compliance. Our calculator handles both scenarios so you always get the right result.
