I am sure that we all have had that one post, which got 100+ likes and 50+ shares and we start wondering if we were to do an ad, how much will that cost. As you can imagine I have wondered that few times myself and after doing a massive amount of research, I have built a calculator which helps me and hopefully, it can help you to evaluate the worth of your organic post as well.
Let me know in the comments if this tool is helpful or how can I improve this.
