Payables Days

Payables Days = (Accounts Payable / Cost of Goods Sold) × 365

This formula converts the accounts payable balance into an average number of days of purchases that remain unpaid.

Input: AP = $50,000, COGS = $500,000

Calculation: (50,000 / 500,000) × 365 = 0.1 × 365

Result: 36.5 days
