About this project

What you'll build: A calculator that takes a price and GST slab (5/12/18/28%) and shows the tax amount and final price, both for tax-inclusive and tax-exclusive inputs.

Why it's a good starter: GST is everywhere in Indian business and the inclusive-vs-exclusive logic is a nice, contained challenge.

What you'll learn: Implementing GST formulas correctly for both directions and validating against real bill examples.
