• Interest Portion of Payment:= IPMT(Interest Rate/12, Payment #, Total Months, -Loan Amount)
• Remaining Loan Balance:= Previous Balance - Principal Payment
• Inventory Turnover Ratio (Monthly): = Sales (Units) / Average Monthly Inventory Value

Conditional Formatting

• Low Stock Alerts: If Ending Inventory Units fall below a predefined safety stock level, cells turn red.
• Late Payment Warning: If a loan payment is overdue (based on current date), the row turns orange.
• Surplus Inventory Highlighting: Cells above 150% of average inventory levels are shaded green to indicate overstocking.
