Volumetric Weight Calculations by WOW Express: Explained

Introduction: The Hidden Challenge in E-commerce Shipping

In India’s fast-growing e-commerce ecosystem, sellers often face a frustrating challenge: weight discrepancies and courier overcharges. Shipping companies rely not just on dead weight (the actual weight of the package) but also on volumetric weight, a measurement based on package dimensions.

When sellers and courier companies calculate weight differently, it leads to:

• Unexpected shipping charges

• Manual disputes that drag on for days

• Customer dissatisfaction due to delayed deliveries

One of the couriers, WOW Express, uses its own volumetric weight calculation formula. While accurate dimensioning is essential, differences between courier formulas can cause disputes and unnecessary costs for sellers.

This blog breaks down WOW Express’s volumetric weight calculation, how it compares to competitors, and how Scandim360’s automated dimensioning system solves the problem for good.

Why Weight Discrepancy Matters in E-commerce

Weight mismatches may seem minor, but they have a direct financial and operational impact:

• Financial Losses: Overcharges per shipment accumulate into significant losses over time.

• Disputes & Delays: Manual dispute resolution with couriers like Shiprocket, Delhivery, or Flipkart Smart Fulfilment eats into valuable time.

• Customer Dissatisfaction: Disputes cause delivery delays, creating a poor buying experience.

• Lack of Transparency: Without accurate proof, sellers can’t challenge incorrect courier bills.

• Wasted Resources: Manual measurement, re-calculations, and follow-ups drain operations teams.

In short, sellers spend more time fighting courier discrepancies than focusing on sales growth.

How Current Practices Create Problems

Today’s shipping ecosystem still depends heavily on manual processes:

1. Manual Weighing & Measuring – Sellers often use tape measures and weighing scales. Small errors in measurement can lead to big volumetric weight differences.

2. Courier Recalculations – Companies like WOW Express may re-measure at warehouses, often leading to higher billed weights.

3. Lack of Proof – Without visual or automated proof, sellers can’t effectively dispute overcharges.

4. Inconsistent Formulas – Each courier (WOW Express, Delhivery, FedEx, BlueDart) uses slightly different volumetric calculation formulas.

These inefficiencies translate into avoidable disputes, extra costs, and mistrust between sellers and couriers.

WOW Express’s Volumetric Weight Formula Explained

WOW Express uses a standard volumetric weight formula similar to global couriers, but with its own divisor:

Volumetric Weight (kg) = (Length × Breadth × Height in cm) ÷ 5000

• If the volumetric weight is higher than the dead weight, the courier charges for volumetric weight.

• If the dead weight is higher, that becomes the chargeable weight.

Example:

• Package dimensions: 40 × 30 × 20 cm

• Volumetric weight = (40 × 30 × 20) ÷ 5000 = 4.8 kg

• Dead weight = 3.5 kg

• Billed weight = 4.8 kg (since volumetric > dead weight).

How It Differs from Competitors

• Delhivery: Uses a divisor of 5000 (similar) but strict rounding rules.

• FedEx / DHL: International shipments often use divisor 6000, meaning slightly lower volumetric weight charges.

• BlueDart: Applies rounding up to next 500 g or 1 kg, leading to higher billed weight.

This means sellers shipping with multiple couriers face constant recalculations, mismatched invoices, and unpredictable shipping costs.
