Import Business Profit Calculator

Import business profit margin.

Calculate import profit from units imported, supplier price, shipping, customs duty, and your selling price into the local market.

What this tool does

This calculator estimates monthly profit for import-based businesses by comparing total revenue against all per-unit costs. It accounts for supplier price, shipping expenses, and import duties applied to your landed cost, then subtracts the combined cost of goods from revenue to show net profit. The result illustrates how changes in monthly volume, supplier pricing, shipping rates, or duty rates affect profitability. Monthly units and selling price typically drive the largest movements in the outcome. A common scenario involves testing how a change in supplier cost or shipping method impacts margin across different monthly volumes. The calculator assumes a simplified duty structure and does not account for additional operational expenses, storage costs, returns, or market fluctuations. This is an educational illustration of basic import business economics.

Import business profit depends on landed cost (supplier + shipping + duty) vs selling price. Typical mark-up: 2-3x landed cost for B2C retail; 1.5-2x for B2B wholesale. Failure mode: founders calculate on supplier price only, miss shipping and duty, realize at shelf that margins don't work.

500 units × 8 supplier + 2 shipping + 8% duty on supplier = 5,320 landed. Selling at 25 retail = 12,500 revenue. Profit 7,180, 57% margin. Strong unit economics for a simple consumer product. At volume scales margins can improve through better shipping rates and bulk duty handling.

Common import pitfalls: MOQs (minimum order quantities) from factories often 5-20k for first order. Lead times 6-12 weeks from 3-6 weeks from Europe. Currency fluctuations over 6-month lead time can move costs 10%+. QA issues where first batch has defects require inspection before shipping, adding cost.

Run it with sensible defaults

Using monthly units of 500, supplier price per unit of 8, shipping per unit of 2, duty of 8%, the calculation works out to 7,180.00. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Monthly Units, Supplier Price per Unit, Shipping per Unit, Duty %, and Selling Price — do not pull with equal force. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.

How the math works

Landed cost = supplier + shipping + duty. Revenue = units × selling price. Profit = revenue - total landed cost.

What the score tells you

Headline financial numbers — income, savings, debt — each tell part of the story. This calculation stitches several together into a single read you can track over time. The value is in the direction, not the absolute number.

What this doesn't capture

The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.

Example Scenario

500 × (££25 - ££8 - ££2 - 8% duty) = 7,180.00.

Inputs

Monthly Units:500
Supplier Price per Unit:£8
Shipping per Unit:£2
Duty %:8
Selling Price:£25
Expected Result7,180.00

Frequently Asked Questions

Typical import profit margin?
Retail consumer goods: 40-60% gross margin. B2B wholesale: 20-35%. Low-ticket items need higher margin % due to fixed costs; high-ticket can work at lower margin %. Below 30% rarely sustainable once overhead and marketing are added.
MOQ challenges?
Factories typically require 500-2000 units minimum first order. For custom items, often 5000+. 5-20k upfront typical for first test batch. Founders often underestimate - think they can start with 100 units, find out factory won't engage.
Customs clearance?
Can be handled DIY (complex, time-consuming) or through customs broker (30-100 per shipment). Brokers handle paperwork, work with the tax authority, classify goods for correct duty rate. Usually worth it for anything over a few thousand units value.
Tariff engineering?
Legal practice of structuring products to qualify for lower-duty HS codes. Example: shipping men's shirts in 'athletic wear' packaging can reduce duty from 12% to 2-4%. Consult customs specialist for legitimate opportunities - not always applicable but can save materially.
