以股票季度净利润为例，同比指的是当前季度净利润数额与去年同季度净利润数额的比值，同比的计算公式：（本季度净利润－去年同季度净利润）/去年同季度净利润*100％。同比说明的是本期发展水平与去年同期发展水平对比的增长率。比如某公司当前一季度净利润是1.1个亿，去年一季度净利润是1个亿，那同比增长率就是：（1.1-1）/1*100%=10%。

环比指的是本季度净利润数额与上个季度净利润数额的比值，环比计算公式：（本季度净利润－上个季度净利润）/上个季度净利润*100％。环比说明的是本期发展水平与上一时期发展水平对比的增长率。比如某公司二季度净利润1.12亿，一季度净利润1.1亿，那二季度环比增长率就是：（1.12-1.1）/1.1*100%=1.81%。
