销售与存货比率及存货与销售比率


销售与存货比率及存货与销售比率商品销售额与商品存货额、商品存货额与商品销售额之间的比率。它是反映市场动向的重要指标，可用来说明商品流转状况和企业经营效果。在批发业，这一比率称为月度存货与销售比率。其计算公式为:月度存货与销售比率-月末商品存货额全月商品销售额这一比率表示月末商品存货额为全月商品销售额的倍数，说明月末商品存货额可供销售多少个月。比率如果上升得快，表示商品存货的增长速度超过了商品销售的增长速度，说明市场上商品销售状况不好，今后需要压缩生产，防止商品存货继续上升;比率如果下降，表示商品销售的增长速度超过了商品存货的增长速度，说明市场上商品销售状况较好，今后需要扩大生产来满足市场需要。 在零售业，这一比率称为年度销售与存货比率。其计算公式为:年度销售与存货比率一全年商品销售额年末商品存货额这一比率表示全年商品销售额为年末商品存货额的倍数。比率上升得快，说明市场销售情况较好;比率下降较多，则说明市场销售情况不很好。
