According to the 2025 Household Financial Welfare Survey, as of the end of March last year, the average assets of households in South Korea were 566.78 million won, while the average debt was 95.34 million won, resulting in an average net worth of 471.44 million won.
Among these assets, financial assets averaged 136.90 million won per household, while physical assets averaged 429.88 million won.
When broken down by the age of the household head, asset sizes increased with age.
Households headed by individuals under 29 had an average asset of 155 million won, those aged 30-39 had 359.58 million won, 40-49 year-olds had 627.14 million won, 50-59 year-olds had 662.05 million won, and those aged 60 and over had 609.5 million won.
Considering average debt, the net worth figures are as follows: for those under 29, the average net worth is approximately 107.96 million won, with a median of 50 million won; for ages 30-39, the average is about 250.60 million won, with a median of approximately 155.85 million won; for ages 40-49, the average is about 483.89 million won, with a median of around 283.84 million won; for ages 50-59, the average is about 551.61 million won, with a median of about 316.85 million won; and for those aged 60 and over, the average is about 535.91 million won, with a median of 250 million won.
Notably, the difference between the average and median values is significant. For those aged 30-39, the average net worth is about 250.60 million won, while the median is approximately 155.85 million won, indicating that the median is about 94.75 million won lower than the average.
The median represents the middle value when households are arranged in order of net worth. Thus, the median figure of 155.85 million won for households in their 30s means that half of these households have a net worth below this amount, while the other half have more.
The trend among younger age groups is particularly striking.
As of the end of March 2025, the average assets of households headed by individuals under 39 decreased by 0.3% compared to the previous year. The National Data Agency noted that while average assets increased in other age groups, they declined only among those under 39.
The average assets for those in their 30s were 359.58 million won, down 0.6% from 361.75 million won the previous year. In contrast, the average for those in their 40s rose by 7.7% to 627.14 million won, and for those in their 50s, it increased by 7.7% to 662.05 million won.
This survey was jointly conducted by the National Data Agency, the Bank of Korea, and the Financial Supervisory Service, with asset, debt, and household characteristics based on data as of March 31, 2025.
