According to the Statistical Center of Iran, median household income of Iran in the fiscal year of 2018–2019 was 434,905,000 rials (a bit above $3,300), an 18.6% rise from the previous yearlong period of 2017–2018, where median household income was about 366,700,000 rials. Adjusted for purchasing power parity, Iran's 2017–2018 median income was equivalent to about $28,647 (2017 conversion factor, private consumption, LCU). As the average Iranian household size is 3.5, this puts median personal income at around $8,185. While Iran rates relatively well on income, median wealth is very low for its income level (on par with Vietnam or Djibouti), indicating a high level of spending. According to SCI, median household spending in the FY 2018 was 393,227,000 rials, or 90.5% of the median household income of 434,905,000 rials.
