Shipping Calculator that Includes Shopify's Discounted UPS Rates

[jj343]

Hi all, does Shopify provide a shipping calculator that includes their discounted UPS rates? For me to calculate profit/margins for prospective products. I saw the below, but it doesn't include Shopify's UPS rates. Most of the items I sell are on the heavier side, so UPS Ground usually ends up being the lowest priced option. Any help would be greatly appreciated!
