I use Junegunn’s Vim plugin [vim-easy-align](https://github.com/junegunn/vim-easy-align/) to make it easier to align my code. This plugin does not have a default mapping for aligning the dollar sign ($). Because the plugin is designed to be extensible, I was able to add support for aligning by the dollar sign ($) by adding some lines to my .vimrc file.
