📝 Formula Summary & Accounting Logic
Core Trading Formulas
Gross Profit (GP) = 2% × Sales
Cost of Goods Sold (COGS) = Sales − Gross Profit
Closing Stock = Opening Stock + Purchases − COGS
Validation Check
Closing Stock = Opening Stock + Purchases − (Sales − GP)
If COGS = Sales − GP, and Closing Stock = OS + P − COGS, then the equation balances.
How It Works
User enters only: Opening Stock, Purchases, and Sales.
Gross Profit is auto-calculated at 2% of Sales.
Closing Stock is auto-calculated using the formula above.
If Closing Stock is negative, a warning is displayed.
