Thanks Adrian!
Ah, I doubt the telcos would show you such calculations, as their plans are structured in a complex manner that gives you a lot of perceived value and features, and each telco always "wins" when comparing itself to the competitor, making consumers confused haha.
But ultimately, I believe what matters is the bottomline of how much you end up spending in addition to your current monthly usage, so the ideal plan varies for each consumer. Hopefully this calculator will help some people make a more informed decision and save a bit of money for them.
