How can I calculate shipping costs using the Flat Rate Green calculator?

Created:   |   Updated:

If you are considering upgrading to a plan that includes Flat Rate Green (the Plus plan and above) or if you are curious to see how much you can save using FRG, you can use ShippingEasy's Flat Rate Green Calculator

To use the calculator, follow these steps: 

  1. Go to
  2. Input dimensions of your package. Each side must be 18” or less and you must round up to the nearest inch if there are decimals - See below for more information. 
  3. Enter the "From" zip code: where the package is shipping from.
  4. Enter the "To" zip code: where the package will be delivered.
  5. Click "Calculate". Your price will be displayed below this button. 
NOTE: The calculator does not currently accept decimals (we are working on adding this functionality). As the measurements and pricing for Flat Rate Green are somewhat broad we suggest rounding up to the next inch.
