GDP per Capita Calculator
From GDP and population, compute GDP per capita = GDP ÷ population, the average output per person, used to compare living standards across regions.
Input Data
Results
At a glance:GDP per capita = GDP ÷ population — average output per person. Total GDP shows scale; per capita removes population size to compare average living standard and development fairly across economies. Higher per capita usually means higher average output/income, a rough living-standard proxy. Cross-country comparison often uses PPP to remove price/exchange differences. But per capita is an average — it hides distribution (high average + huge inequality ≠ most are well off) and excludes non-market activity, environment and quality of life. Pair with the Gini coefficient and median income for a fuller picture.

GDP per capita examples
| Case | GDP (HK$) | Population | Per capita (HK$) |
|---|---|---|---|
| A | 14,300,000,000 | 7,500,000 | 1,906.67 |
| B | 3,000,000,000,000 | 7,500,000 | 400,000.00 |
| C | 143,000,000 | 7,500,000 | 19.07 |
Per capita = GDP ÷ population. Same population: bigger GDP → higher per capita. Compare average wealth by per capita, not total GDP.
Case Studies
Case 1: GDP and population to per capita
Economy: GDP = 3,000,000,000,000 (3 trillion), population = 7,500,000.
Per capita = 3,000,000,000,000 ÷ 7,500,000 = 400,000 HK$.
About 400k per person of annual output. Per capita removes population size so economies compare fairly per person, better than total GDP for development.
Case 2: Big total GDP need not mean richer people
A: GDP 6 trillion, population 40 million; B: GDP 3 trillion, population 7.5 million.
A per capita = 6,000,000,000,000 ÷ 40,000,000 = 150,000; B per capita = 3,000,000,000,000 ÷ 7,500,000 = 400,000.
A's total GDP is 2× B's, but with 5.3× the population, its per capita is only ~3/8 of B's. Clear: compare average wealth by per capita; total GDP misleads via population scale.
FAQ
Why compare per capita, not total GDP?
They answer different questions. Total GDP is overall scale — a large-population country can have huge GDP yet be poor per person; a small rich region can have modest GDP but high per-person output. Comparing average wealth by total GDP is unfair, like comparing firms by revenue not per-employee. Per capita removes population size so economies compare on an equal per-person basis, better reflecting development and average income. Example: A's total GDP is 3× B's, but A's population is 5× B's, so A's per capita is actually lower — B's people are on average richer. For 'who is more developed/wealthy', per capita is the better metric.
What is PPP-adjusted per capita GDP?
PPP-adjusted per capita GDP removes cross-country price and exchange-rate differences for a fairer living-standard compare. Converting each country's per-capita GDP at market exchange rates ignores that the same money buys different amounts locally — in low-price areas, the same nominal income buys more (stronger real purchasing power); market rates often miss this, especially for non-tradable services (haircuts, dining, rent). PPP uses a basket of identical goods/services priced locally to derive a purchasing-power conversion rate, then converts per-capita GDP. After PPP, low-price areas are usually 'raised', high-price areas 'lowered', reflecting real living standards better. For rigorous international living-standard comparison, economists use PPP-adjusted per capita GDP, not market-rate figures. Pair with the PPP calculator.
Does high per capita mean everyone is wealthy?
Not necessarily — per capita is an average, blind to distribution. Two places with identical per capita: one fairly equal (most comfortable), one highly concentrated in a few rich (most struggling) — same average, vastly different lives. Averages are pulled up by extreme highs, masking most people's reality. So judge 'everyone wealthy' with distribution indicators, mainly the Gini coefficient (0 = equal, 1 = unequal) and median income (the middle person's, more typical than the mean). Per capita also excludes non-market activity, environment, health and education. So per capita is useful for average output, but pair with Gini, median income and social indicators for true well-being. Pair with the Gini calculator.
GDP per capita vs GNI per capita?
They differ by statistical boundary — one is geographic, the other by nationality. GDP per capita = GDP ÷ population, territorial (what is produced within borders, by anyone). GNI per capita = GNI ÷ population, by nationality (what residents earn, incl. overseas earnings minus foreigners' local earnings). GNI = GDP + net foreign factor income. Big difference when: foreign factories abound (profits repatriated) → GDP per capita may exceed GNI (much produced locally, little kept by residents); or large outward investment (much overseas income) → GNI exceeds GDP. For 'domestic activity and jobs' use GDP per capita; for 'residents' actual average income' use GNI per capita. The World Bank groups countries by GNI per capita, not GDP.
Why PPP not exchange rates for cross-country compare?
Comparing per capita GDP only at market exchange rates understates low-price countries' real living standards, so rigorous comparison uses PPP. The issue: one US dollar buys very different amounts across countries. In low-price areas the same nominal income buys more (stronger real purchasing power); but market rates mainly reflect tradable goods and capital flows, missing non-tradable services (haircuts, dining, rent) that are especially cheap in low-price countries. Result: market-rate conversion systematically understates low-price countries' living standards. PPP prices a basket locally to derive a real purchasing-power rate, then converts; after PPP, low-price areas are 'raised', high-price 'lowered', fairer. So: for nominal scale or import power use market-rate per capita GDP; for real living standards use PPP-adjusted. Pair with the PPP calculator.
