Kernvel Shipping Calculator

Kernvel Shipping Calculator displays live shipping rates on your product pages, helping customers see delivery costs before they reach checkout. The app pulls from your existing Shopify shipping rates and shows them based on country, province, and ZIP code—without changing what you charge. Unexpected shipping costs are a common reason shoppers abandon their carts. By showing shipping information earlier in the shopping journey, you reduce uncertainty and help customers make informed decisions. The customizable free-shipping progress bar encourages shoppers to add more items to reach shipping goals. You can add the shipping progress bar to your cart or cart drawer and configure up to 8 promotional goal tiers. Customize colors, fonts, labels, border radius, and placement to match your store's design. The app also helps you identify countries where customers receive no shipping rates, so you can address potential delivery issues.
