Selected Portion = Contract Amount × Percentage ÷ 100
Balance Due = Selected Portion − Already Paid
Remaining Contract = Contract Amount − Selected Portion
Full Contract = Known Amount ÷ (Percentage ÷ 100)
Remaining Value = Full Contract − Known Amount
Profit Value = Base Cost × Profit Rate ÷ 100
Quote Before Tax = Base Cost + Profit Value
Final Quote = Quote Before Tax + (Quote Before Tax × Tax Rate ÷ 100)
Platform Fee = Contract Amount × Platform Fee Rate ÷ 100
Net Income = Contract Amount − Platform Fee − Tax − Expenses
Percentage Change = (New Contract − Old Contract) ÷ Old Contract × 100
