Use this calculation when every balance, flow, and elapsed period follows the same accounting basis, currency, entity boundary, and reporting period. It is useful for a reproducible schedule or analytical cross-check, but the result should still reconcile to the ledger.

Days sales outstanding

Days sales outstanding: average collection period for receivables in days.

Days inventory outstanding

Days inventory outstanding: average time inventory is held before sale, in days.

The implemented rule is: Calculate the operating cycle in days as days sales in inventory plus days sales outstanding, the time from acquiring inventory to collecting cash from sales.^[1]

Operating cycle

Operating cycle length in days; shorter cycles convert inventory to cash faster.

The calculator applies the stated arithmetic and does not decide whether a recognition method or classification is permitted under a particular accounting framework. Estimates, cutoff errors, seasonality, acquisition effects, inconsistent averages, and differing policies can make a mathematically correct result misleading.

Reconcile the inputs to the general ledger and supporting schedules. For reporting decisions, compare the result with the entity's accounting policy, applicable GAAP or IFRS guidance, prior-period disclosures, and an accountant's review.

• Cash Conversion Cycle Calculator

  Calculate the cash conversion cycle in days as days inventory outstanding plus days sales outstanding minus days payable outstanding.

• Inventory Turnover Calculator

  Calculate inventory turnover as cost of goods sold divided by average inventory, measuring how often inventory is sold and replaced per period.

• DSO Days Sales Outstanding Calculator

  Calculate days sales outstanding as average accounts receivable divided by credit sales, times the number of days in the period.
