Returns to Education
Returns to education measure how much an extra year of schooling raises a person's earnings. The World Bank's global database, compiled by Psacharopoulos and Patrinos, finds the average private return is about 9% per year, with the highest returns in Latin America and Sub-Saharan Africa and for higher education. Returns are consistently larger for women than for men.
Key Returns to Education Insights
Roughly 9% per extra year
Across 1,120 estimates in 139 countries, the average private return to one more year of schooling is 8.8% and has stayed near 9% for decades. The most recent estimate per country averages 9.5%.
Highest in Latin America and Africa
Private returns peak at 11.0% in Latin America & the Caribbean and 10.5% in Sub-Saharan Africa, where human capital is scarcer, and are lowest at 5.7% in the Middle East & North Africa.
Tertiary education pays the most
Private returns to higher education average 15.8% and have risen over time, overtaking secondary (15.1%). Primary still shows the highest social returns at 17.5%.
Bigger payoff for women
Private returns to female education exceed those for men by about two percentage points, a gap that has widened, making girls' education a development priority.
Private Return per Year of Schooling by Region
Average private rate of return to one additional year of schooling, by world region, from the pooled global database.
Key Finding: Latin America (11.0%) and Sub-Saharan Africa (10.5%) lead; the Middle East & North Africa is the outlier at 5.7%.
Private Returns by Level of Education
Average private rate of return at primary, secondary, and higher education, estimated with the full-discounting method.
Key Finding: Primary education returns highest at 25.4%, while higher education (15.8%) now edges out secondary (15.1%).
Private vs Social Returns by Level
Comparison of private returns (to the individual) and social returns (which add the public cost of schooling) at each level.
Key Finding: Social returns are always lower because they count public subsidies; the gap is widest at higher education (15.8% vs 10.5%).
Returns to Schooling: Women vs Men
Average private Mincerian return per year of schooling by gender, pooled across the global database.
Key Finding: Women earn about 12% per extra year versus about 10% for men, roughly a two percentage point advantage.
Average Return per Year of Schooling Over Time
How the overall Mincerian return to a year of schooling has evolved across successive global reviews.
Key Finding: Returns have stayed remarkably stable near 9%, edging up from 8.7% pre-2000 to 9.1% after 2000.
Understanding Returns to Education
Private vs social returns
The private rate of return compares the extra lifetime earnings an individual gains from schooling against their private costs (tuition, fees, and foregone earnings while studying). The social rate of return adds the public cost of education, such as government spending on buildings and teacher salaries, to those private costs. Because researchers can measure full social costs but not the broader social benefits of education, social returns are always lower than private returns, and the gap reflects how heavily a level of schooling is publicly subsidized.
The Mincerian method
Most modern estimates use the Mincerian earnings function (after Jacob Mincer, 1974), a regression of log wages on years of schooling plus work experience. The coefficient on schooling is read directly as the average percentage gain in earnings from one additional year of education. The World Bank database also includes older full-discounting estimates, which equate the present value of lifetime earnings with costs and are used to compare returns across primary, secondary, and higher education levels.
Why returns differ by level and region
Returns follow a classic pattern: they are higher where schooling is scarcer. That is why low-income countries (9.3%) and regions like Sub-Saharan Africa and Latin America post some of the highest returns, while advanced economies with near-universal schooling see lower returns. By level, primary education historically yielded the highest returns, but returns to higher education have risen as labor markets reward advanced skills, raising new questions about financing and equity.
Caveats
Mincerian estimates can suffer from ability bias (more able people both earn more and study longer) and credentialism (degrees signal productivity rather than create it), which can inflate measured returns. Returns are averages that mask wide variation across fields, individuals, and over time, and they capture earnings gains rather than the full private and social value of education. The database pools 1,120 estimates from 139 countries spanning 1950–2014, so figures blend many study designs and eras.
