Tier Prcing not showing on Magento 2.2.4
Solution
This issues are using the custom theme, so the update cart template was changed.
Please check vendor/magento/module-configurable-product/view/base/templates/product/price/tier_price.phtml
to see how tier prices are shown on product page and then fix in your theme.
In Magento 2.2.4 Tier price of a simple product does not appear on a configurable product page
Also Please update your tier price, its belongs to simple price not for whole qty, I check your screenshot its showing for whole qty price..
i mean if your product price is $20
than if 2qty than set price 19.5 not for 39
if 3qty than set price 19 not for 57 etc...
i hope its work for you
