What is Import Duty?
The Import Duty calculation tells you your total landed cost from a few simple inputs. The figure you are solving for here is the total landed cost, expressed in INR.
The Import Duty formula
The core formula is:
Total landed cost = Goods value + Goods value × Customs duty rate ÷ 100 + (Goods value + Goods value × Customs duty rate ÷ 100) × Import tax ÷ GST rate ÷ 100Here is what each input means:
- Goods value — a money amount. Example: ₹50,000.
- Customs duty rate — a percentage, such as an annual rate. Example: 1%.
- Import tax / GST rate — a percentage, such as an annual rate. Example: 18%.
How to calculate it step by step
- Write down the goods value (for example, ₹50,000).
- Write down the customs duty rate (for example, 1%).
- Write down the import tax / gst rate (for example, 18%).
- Apply the formula above to get your total landed cost.
- Double-check the result with the Import Duty Calculator.

|---|---|
| Total landed cost | ₹32,450.00 |

Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
- Annual rates must be converted to the period you are calculating for (for example, divide an annual rate by 12 for a monthly figure).
