Use Our Weight-Based Spreadsheet Formula to Compare Total Costs Before Checkout

Unexpected shipping fees are a common checkout surprise that can deray a great deal. At VigorBuy, we empower smart shoppers with a proactive solution: the VigorBuy Shipping Estimator Spreadsheet. Learn how a simple, weight-based formula can bring transparency and savings to your cross-border purchases.

How the Weight-Based Formula Works

Shipping carriers primarily use volumetric weightactual weight—whichever is greater—to calculate costs. The core formula is straightforward:

Shipping Cost = Base Rate + (Weight × Rate per Kg)

By inputting the product weight (in kg or lbs) into your spreadsheet, you can dynamically estimate charges from major logistics providers.
