Air Freight Cost Calculator — Chargeable Weight to Freight Estimate
Answer: Air freight cost = chargeable weight (kg) × lane rate, then apply fuel surcharge and take the higher of the result and the carrier minimum charge.
What is air freight cost?
Air freight cost is what an airline or forwarder bills you to move cargo from origin airport to destination airport. It is dominated by chargeable weight × lane rate, then layered with fuel surcharge, security/screening, and a per-shipment minimum. This calculator returns the linehaul slice — the number most useful for budgeting before you have a forwarder RFQ in hand.
How the calculator works
Enter four numbers:
- Chargeable weight (kg) — the higher of actual scale weight and volumetric weight. For air, volumetric weight = (L × W × H in cm) ÷ 6000.
- Rate per kg — the base air freight rate for your lane (China–US, Vietnam–EU, India–US, etc.).
- Fuel surcharge % — applied to the base freight. As of May 2026 this is typically 18–28% on transpacific lanes.
- Minimum charge — the floor your carrier or forwarder applies on small shipments, usually 80–200 USD.
The calculator returns:
- Base freight = chargeable weight × rate
- Surcharge = base × fuel surcharge %
- Estimated total = max(base + surcharge, minimum charge)
Rate reference (as of May 2026)
Spot rates change weekly. The ranges below are typical for general cargo, 100–500 kg, non-peak season.
| Lane | Rate per kg (USD) | Notes |
|---|---|---|
| China (PVG/CAN) → US West Coast (LAX) | 4.50 – 6.80 | Direct lift, general cargo |
| China (PVG/CAN) → US East Coast (JFK/ORD) | 5.50 – 7.80 | Direct or one-stop |
| China → Europe (FRA/AMS) | 4.80 – 6.50 | General cargo |
| Vietnam (SGN/HAN) → US | 5.20 – 7.50 | Often consolidated |
| India (BOM/DEL) → US | 4.00 – 6.20 | Belly-cargo dependent |
Q4 peak season (mid-September through mid-December) typically adds 1.00–2.50 USD/kg on top.
Worked example
You are shipping 8 cartons from Shenzhen (CAN) to Los Angeles (LAX). Each carton is 60 × 40 × 35 cm and weighs 18 kg.
- Volumetric weight per carton = (60 × 40 × 35) ÷ 6000 = 14 kg → use actual 18 kg
- Total chargeable weight = 18 × 8 = 144 kg
- Lane rate = 5.20 USD/kg, fuel surcharge = 22%, minimum = 150 USD
- Base freight = 144 × 5.20 = 748.80 USD
- Surcharge = 748.80 × 0.22 = 164.74 USD
- Estimated total = max(913.54, 150) = 913.54 USD
That is your linehaul-only number. Add customs entry (~125 USD), destination delivery, and any duty before comparing landed cost against ocean LCL.
Air vs ocean vs courier — when to use which
| Mode | Best for | Transit | Typical price band |
|---|---|---|---|
| Express courier (DHL/FedEx) | Under 50 kg, urgent | 3–5 days | 6.00 – 12.00 USD/kg |
| Air freight (this tool) | 50–2000 kg, time-sensitive | 5–10 days door-to-door | 4.50 – 7.50 USD/kg |
| Ocean LCL | 2–15 CBM, cost-sensitive | 30–45 days | ~80–180 USD/CBM |
| Ocean FCL | Over 15 CBM | 30–45 days | flat per container |
For shipments in the 100–500 kg range with retail urgency (FBA replenishment, launch SKUs), air freight is usually the right mode. Below 100 kg, courier often beats forwarder-managed air. Above 2000 kg, ocean LCL or FCL usually wins on cost even with longer transit.
FAQs
What weight should I enter?
Enter chargeable weight. Compute volumetric weight (L × W × H in cm ÷ 6000) for each carton, take the higher of that and actual weight, and sum across all cartons. The chargeable weight calculator linked below does this for you.
Does the rate already include fuel?
Usually no. Forwarders quote a base rate and a separate fuel surcharge so the surcharge can move with jet fuel index changes. Some all-in rates do bundle fuel — if yours does, enter 0 in the surcharge field.
Why is the minimum charge field there?
Small shipments under ~45 kg often fall below the carrier’s revenue floor. The floor protects the forwarder’s fixed handling cost. If your weight × rate × surcharge total is below the floor, you pay the floor.
What surcharges are NOT modeled here?
Security/screening (~0.15–0.30 USD/kg), AWB fee (~25–50 USD), origin handling, destination terminal handling, battery/DG fees (50–150 USD), and overweight piece fees on cartons over 150 kg. For a clean budget, add roughly 5–10% on top of this calculator’s output to absorb those.
How does this compare with a real forwarder quote?
A weight × rate × surcharge model is normally within 10–20% of a live quote on stable lanes. The gap comes from space conditions, seasonal peaks, cargo profile (battery, magnetic, liquid), and whether the booking is direct or routes through a transfer hub.
Dated facts
As of May 2026, transpacific air freight rates have stabilized in the 4.50–7.50 USD/kg band for general cargo after Red Sea diversion pressure in 2024–2025 eased. Fuel surcharge percentages on most forwarder quotes sit between 18% and 28%, reset weekly off the jet fuel index. The IATA volumetric divisor remains 6000 cm³/kg, and the 6.0 dimensional factor for in/lb conversion is unchanged at 166 in³/lb.
Frequently asked questions
- How is air freight cost calculated?
- Air freight is billed on chargeable weight (the higher of actual weight and volumetric weight). The base freight is chargeable weight × lane rate per kg. Carriers and forwarders then add fuel surcharge, security/screening fees, and apply a minimum charge floor. This calculator captures the dominant linehaul math; airport handling, customs, and destination delivery are extra.
- What is volumetric weight for air freight?
- IATA standard volumetric weight = (L × W × H in cm) ÷ 6000, giving a kg figure. If your shipment is light and bulky, that number is higher than actual weight, so it becomes the chargeable weight. Express couriers like DHL and FedEx use a stricter divisor of 5000.
- What is a typical air freight rate per kg from China to the US in 2026?
- As of May 2026, general-cargo air freight rates from major Chinese gateways (PVG, CAN, HKG) to US gateways (LAX, ORD, JFK) commonly fall in the 4.50–7.50 USD/kg range for 100–500 kg shipments, with general consol routings near the low end and direct air below 100 kg near the high end. Battery cargo, dangerous goods, and Q4 peak season run materially higher.
- Does this calculator include customs duty, taxes, or destination delivery?
- No. This is a linehaul-only estimate — the slice that goes from origin airport to destination airport plus fuel surcharge. Customs entry, duty, MPF/HMF, last-mile delivery, and any battery or DG handling surcharges sit outside this number and must be quoted separately.
- When does the minimum charge kick in?
- On small shipments — typically under 45 kg chargeable weight — carriers and forwarders apply a minimum revenue floor (often 80–200 USD depending on lane and agent). If your weight × rate math comes out below that floor, you pay the floor, not the math.
- How accurate is a calculator estimate vs a real quote?
- A weight × rate × surcharge model is normally within 10–20% of a live quote on stable lanes, which is good enough for pre-RFQ budgeting. The gap comes from space conditions, seasonal peaks, cargo profile (battery, magnetic, liquid), and whether the booking is direct or via a transfer hub. Always validate with a live forwarder quote before committing to a PO.
