Keep this baseline in mind: on average worldwide, each additional year of schooling yields a personal return of roughly 9% per year.
Globally, each extra year of formal schooling translates into about a 9% annual increase in personal income; this benefit tends to be higher for women than for men. This figure applies to regular schooling, not to short courses or workshops. Think of it as a yardstick: if a course costs 30,000 yuan and lasts half a year, ask whether its expected income boost matches what one extra year of schooling would deliver.

No cost at all. Memorize this figure and use it as a benchmark for evaluating any “learning opportunity.”
A comprehensive review covering 1,120 estimates from 139 countries between 1950 and 2014 found that the worldwide average private return on each additional year of schooling is 9% per year. This private return is the portion that directly affects an individual’s earnings — on average, an extra year of schooling raises income by 9%. The private return on higher education is on the rise, while the social return on education (the benefit to society as a whole) remains substantial. Women continue to reap higher average returns than men from schooling.

Open source linkThis is a global average for “one extra year of schooling” and should not be taken as the expected return from a single course or workshop, nor as a figure specific to China. It serves merely as a rough reference point. Its main purpose is to provide a standard for evaluating any training program: if a course demands a 30,000‑yuan investment and six months of effort, you can gauge whether its income impact is comparable to that of one additional year of formal education. Keep in mind that this average masks considerable differences across fields and countries.
