适用于永续盘存制吗？Does it work for perpetual inventory?
本页按会计等式示意：期末存货 = 期初存货 + 本期采购 − 销货成本。永续盘存制会随每笔交易更新存货，但期末结果应满足同一等式；具体计价方法（先进先出、加权平均）需另行计算销货成本。It uses the accounting identity: ending = beginning + purchases − COGS. A perpetual system updates stock with each transaction, but its period-end figure satisfies the same identity; the costing method (FIFO, weighted average) is needed to get COGS itself.
能举个计算实例吗？Can you show a worked example?
例如在「期末存货」中填 期初存货 = 20000，购进 = 50000，销货成本 = 45000，结果区显示：期末存货：25,000.00For example, entering Beginning = 20000, Purchases = 50000, COGS = 45000 in the Ending Inventory Calculator gives: Ending inventory: 25,000.00
