⚙️ Core Mathematics Formulas
Forward Addition
Multiplies your net amount cleanly against the target percentage rate, appending that yield directly onto base costs.
Reverse Extraction
Divides inclusive pricing layers using proportional constants to pull out hidden net costs precisely.
💼
Gross Price
The full commercial amount displayed at retail checkouts, encompassing both raw production items and mandatory tax obligations.
📑
Net Base
The clean baseline evaluation value before government statutory rules or consumer adjustments apply.
GST / VAT Addition Formula
Gross = Net × (1 + Tax Rate / 100)
Where Gross is your retail ticket cost, and Net represents the starting pre-tax evaluation benchmark.
Frequently Asked Questions
When tax is added, the rate is calculated based on the original *smaller* net amount. If you subtract that same percentage from the new *larger* gross total, you will end up removing too much money. Proper reverse calculation divides by `1 + (Rate / 100)` to restore balance.
Functionally, the underlying math remains identical. Value Added Tax (VAT) applies incrementally at various production stages, while Goods and Services Tax (GST) usually triggers as a single unified consumption item. Both use the exact same percentage math.
