Shopify Shipping Rate Calculator

Estimate carrier costs and dimensional weight to set accurate manual rates.

5000 (Standard Courier/Express) 6000 (Some Ground Services) 4000 (Specialized)
Actual Weight: 0 kg
Volumetric Weight: 0 kg
Chargeable Weight: 0 kg
Total Estimated Cost: $0.00
Alert: Your package is charged based on size (Volume), not actual weight.

Understanding Shopify Shipping Calculations

Setting up shipping rates in Shopify can be one of the most challenging aspects of launching an e-commerce store. If you undercharge, you lose profit on every sale. If you overcharge, you risk cart abandonment. This calculator helps you estimate the True Chargeable Weight and total cost of shipping a package so you can configure your Shopify shipping profiles accurately.

How Shopify Shipping Works

When you set up shipping in Shopify, you generally have three options:

  • Calculated Rates: Real-time rates from carriers like UPS, FedEx, or USPS based on package weight and dimensions.
  • Flat Rates: A set price per order or weight range.
  • Free Shipping: Usually applied on orders over a certain dollar amount.

The "Calculated Rates" method is the most accurate, but many merchants prefer Flat Rates to simplify the customer experience. To set a Flat Rate that doesn't lose money, you must understand how carriers bill you.

The Hidden Cost: Volumetric Weight

One of the biggest mistakes Shopify merchants make is ignoring Volumetric (Dimensional) Weight. Carriers do not charge based solely on how heavy an item is; they also charge based on how much space it takes up in the truck or plane.

The formula for Volumetric Weight (in kg) is usually:

(Length x Width x Height) / Divisor

The standard divisor is 5000. If the Volumetric Weight is higher than the Actual Weight, the carrier will charge you for the Volumetric Weight. This is known as the "Chargeable Weight."

Using This Calculator

Use this tool to simulate what a carrier might charge you for a specific product or box size:

  1. Actual Weight: Weigh your product including the box and bubble wrap.
  2. Dimensions: Measure the outer dimensions of your shipping box.
  3. Carrier Rates: Input your negotiated or standard base rate and cost per kg (check your carrier's rate sheet).
  4. Handling: Add the cost of the box, tape, and labor.

The result gives you a baseline "break-even" shipping cost. You should set your Shopify manual rates at or above this value to ensure profitability.

You will be charged for the size.'; } else { alertBox.style.display = 'none'; } // Show result container document.getElementById('result-container').style.display = 'block'; }
