How to make # url crawlable

Hi,

I have an url abc.com/#/emi-calculator

Currently this url is not being crawled and indexed by google since it contains a "#" in it.

After some research i found that if we use "#!" Then the url will be crawlable.
But this method recommended for SEO? Or should i just go ahead and create a new page and host my emi calculator there?
