Jump value is the monetary difference between your current salary and what potential employers are courting you with. 

所谓的“跳槽价值”指你的当前薪资与潜在雇主招募你时承诺的薪资之间的差距。

比如，你现在每月8000元，有个公司想招你过去，承诺每个月给你1万，那么你的jump value就是2000元。

This was common in the 1990s with web developers and solution architects when they were switching jobs frequently to have jump values of five figures when all bonuses and incentives were calculated. This number was often compared against the potential for salary hikes with an existing employer over x years, but also as a way to gauge one's 'rank' or value in the .com revolution.

这个说法在20世纪90年代的时候在网络研发人员和方案工程师当中特别流行，他们频繁跳槽，所有奖金和津贴之类加起来，跳槽价值能达到五位数。他们通常会用跳槽价值来跟当前就职公司在未来n年里的涨薪幅度作比较，同时，这个跳槽价值也能体现一个人在互联网领域的地位和价值。
