Free-shipping threshold calculator
A free-shipping threshold bar is a small banner that shows shoppers how much more they need to add to their cart to unlock free shipping. It turns a vague perk into a concrete, beatable target, which is why it is one of the most reliable ways to lift average order value: shoppers add one more item to clear the bar instead of checking out with a cart that was almost there. Because the bar travels with shoppers from the landing page to the cart, the reminder stays in view at the moment it matters most. Use the calculator to enter a sample cart total and see the exact progress message your store would show.

How it works
Enter a cart total above. The calculator compares it against an example free-shipping threshold and shows how much more the shopper needs to add, along with how far along they are as a percentage. That is the same nudge a live bar would display on every page of your store. Once the cart clears the threshold, the message switches to confirm that free shipping is unlocked. Try a few totals just below and just above the line to see how the wording changes as a cart gets closer.
Take it live on your store
The calculator previews the message; BoostPop shows it to real shoppers. Set your own threshold, style the bar to match your theme, and it renders on the first paint of every page with no theme edits and no developer required.
