Export Duty Calculator – Export Taxes, Levies, Rebates and Net Profit
The Export Duty Calculator helps exporters understand how export duty, levies, rebates and logistics costs affect the real profitability of an export shipment. Instead of working with separate spreadsheets for FOB value, surcharges and rebates, this tool combines everything into five connected modes that focus on practical decisions: what you earn, what you pay and what remains as net profit.
Export regimes differ from country to country. Many products are fully exempt from export duty, while some raw materials, agricultural goods or strategic items may carry export taxes or special cess. At the same time, governments often offer export incentives such as rebates and duty drawbacks to encourage value-added exports. This calculator is designed to handle all of these elements in a simple, scenario-based way.
How the Export Duty Calculator Works
The calculator is divided into five modes so that you can focus on specific questions or build a complete picture step by step:
- Export Duty: Calculates export duty and export levies from FOB value and shows the effective export tax rate.
- FOB / CFR / CIF: Builds export values under different Incoterms using factory price, inland transport, port charges, freight and insurance.
- Export Levies: Aggregates multiple export levies such as cess, promotion and social or conservation charges.
- Rebate / Drawback: Estimates export rebates or duty drawbacks as a percentage of FOB value plus any refund of duty on inputs.
- Net Export Profit: Combinesenue, production costs, logistics, export taxes and other expenses to show net export profit and margin.
The default export duty rate is set to 0 percent, reflecting that many exports are duty-free. You can override all rates and amounts to match your own country, product and shipment.
Mode 1: Export Duty from FOB Value
The Export Duty mode starts with FOB value, which represents the value of goods at the port of shipment, including loading costs but excluding international freight and insurance when using classic FOB terms. You input FOB value, export duty rate and any additional export levies as percentages.
Export Duty and Levies Formula
Export Levies = FOB Value × Levies Rate%
Total Export Taxes = Export Duty + Export Levies
Net FOB After Export Taxes = FOB Value − Total Export Taxes
The calculator also reports the effective export tax rate as a percentage of FOB value. This is useful when comparing how export taxes affect different products or markets.
Mode 2: FOB, CFR and CIF Export Values
The FOB / CFR / CIF mode helps you understand how different Incoterms change the export value basis. You start with goods value at the factory and add inland transport to the port, port and handling charges, international freight and insurance. The tool then builds FOB, CFR and CIF values.
Export Value Formulas
CFR Value = FOB Value + Freight
CIF Value = CFR Value + Insurance
In addition to the three values, the calculator also shows how much of CIF value is pure goods value and how much comes from logistics and insurance. This helps exporters and buyers see where costs are concentrated and which components are most sensitive to change.
Mode 3: Export Levies and Surcharges
Some countries apply several types of export levies on the same shipment, such as export cess, export promotion levies and social or conservation charges. Instead of adding them manually each time, the Export Levies mode lets you enter allevant percentages in one place.
Export Levies Formula
Promotion Levy = FOB × Promotion Rate%
Social or Conservation Levy = FOB × Social Rate%
Other Levies = FOB × Other Rate%
Total Levies = Cess + Promotion Levy + Social Levy + Other Levies
Net FOB After Levies = FOB − Total Levies
The mode summarizes the total levies both as an amount and as a percentage of FOB, which is helpful when negotiating prices or checking whether an export market remains profitable under new levy structures.
Mode 4: Export Rebate and Duty Drawback
Export incentive schemes often provide refunds based on a percentage of FOB value or a refund of duties paid on imported inputs. The Rebate / Drawback mode lets you enter a rebate rate and any additional refund amounts tied to input duties.
Export Rebate Formula
Total Rebate = Rebate from Rate + Duty Paid on Inputs
Netenue Including Rebate = FOB + Total Rebate
Effective Rebate Rate = Total Rebate ÷ FOB × 100
This helps exporters understand the full benefit of incentive schemes and how they change the true export price received, especially when comparing markets with and without rebates.
Mode 5: Net Export Profit After All Costs
The Net Export Profit mode brings everything together. You enter FOB price per unit, quantity, production cost per unit, total logistics cost, export taxes and levies, and other export expenses such as bank charges or commissions. The calculator shows totalenue, total costs, net profit, profit per unit and profit margin.
Net Export Profit Formula
Production Cost Total = Production Cost per Unit × Quantity
Total Export Costs = Production Cost Total + Logistics Cost + Export Taxes and Levies + Other Export Expenses
Net Export Profit = Exportenue − Total Export Costs
Profit per Unit = Net Export Profit ÷ Quantity
Profit Margin% = Net Export Profit ÷ Exportenue × 100
This mode is especially useful for exporters who want to check whether a particular order or market remains profitable after taking into account all visible export-related charges.
Why Use an Export Duty and Net Profit Calculator?
Export decisions are often made on tight margins, and small changes in duty rates, logistics costs or rebate schemes can turn a profitable order into a loss. By using a structured calculator, you can break the problem into clear components and test different scenarios before committing to a price or shipment volume.
Some practical uses include:
- Checking how much export duty and levies reduce the net FOB value you receive.
- Comparing FOB, CFR and CIF pricing when negotiating Incoterms with buyers.
- Estimating the benefit of export rebate or duty drawback schemes.
- Testing how changes in freight rates or export duty rates affect profit margins.
- Evaluating whether to accept, renegotiate or decline a low-margin export order.
Limitations and Assumptions
This export duty calculator is designed for planning and education, not for legal or tax compliance. Among its limitations are:
- It does not include official export duty tables or HS-specific rates; you must enter the correct percentages yourself.
- It assumes percentage-based export duty and levies and does not model specific duties per unit or mixed formulas.
- It treats logistics as a single cost figure and does not consider multi-leg contracts or complex allocation rules.
- It does not handle currency conversion or exchange rate risk between invoicing and settlement dates.
- Some export incentive schemes use detailed formulas or caps that are not represented here.
For binding calculations, exporters shouldy on guidance from customs authorities, trade consultants, logistics providers and tax advisors, and should always verify rates and eligibility rules before making commitments.
How to Use This Tool Effectively
- Start with the FOB / CFR / CIF tab to understand your export value under different delivery terms.
- Use the Export Duty and Export Levies tabs to see how export taxes influence net FOB value.
- Switch to the Rebate / Drawback tab to add incentives and see how they change your effective export price.
- Finish with the Net Export Profit tab to check whether a specific shipment is financially attractive after all costs.
- Run multiple scenarios with different freight rates, export duty rates and rebate percentages to understand risk and sensitivity.

Frequently Asked Questions Export Duty and Net Export Profit
Find quick answers to common questions export duty, export levies, rebates, FOB/CIF values and export profit calculations.
Many products in many countries have no export duty, so 0 percent is a neutral starting point. If your product is subject to export duty, you can simply enter the correct percentage for your HS code and country.
No. The calculator does not have a built-in HS tariff database. You need to obtain the correct duty and levy rates from your customs authority, trade portal or customs broker and then input them manually into the calculator.
FOB value includes goods, inland transport and port handling to the export port. CFR adds international freight, and CIF adds insurance as well. The FOB/CFR/CIF tab helps you see how much cost is goods and how much is logistics.
The rebate and drawback mode shows the potential refund based on your FOB value and eligible input duties. You can use this to understand how much government incentives increase your effective export price and to plan pricing or reinvestment strategies.
No. The net export profit mode assumes all amounts are in the same currency and settled without delay. If exchange rate risk or long payment terms are important for your business, you should add those effects separately in your financial planning.
The calculator is suitable for quick scenario analysis for exporters of any size, but large exporters will usually supplement it with detailed ERP, cost accounting and trade compliance systems. Treat it as a fast planning and education tool rather than a full compliance engine.
