Anu Aga Net Worth

Anu Aga has an estimated net worth of $2.6 billion, according to Forbes Real-Time Billionaires, Anu Aga profile (figures as of October 20, 2026). That is up from $1.4 billion in 2018.

Anu Aga is an Indian businesswoman and social worker best known for leading Thermax, an energy and environment engineering company. She joined Thermax in 1985 and later ran its human resources division from 1991 to 1996. In 1996, she became chairperson and led the business until 2004. After that, her daughter Meher Pudumjee took over the top role, while Aga stayed linked to the company and shifted more of her time toward public service and education work.

Her wealth comes from a majority stake in Thermax, a listed engineering firm in the construction and engineering field. Forbes put her net worth at $2.6 billion on its real-time billionaires tracker as of October 20, 2026. Outside business, she cofounded Teach for India in 2008, a non-profit that recruits young people to teach for 2 years in schools serving low-income children. She was also a nominated member of parliament in India’s upper house.

How Anu Aga built her fortune

Aga’s fortune is tied to Thermax. Forbes says her wealth comes from a majority stake in the listed engineering company. Thermax works in energy and environment engineering, which made Aga one of India’s best-known business leaders. Her rise at the company was gradual. She started there in 1985, led human resources from 1991 to 1996, and then served as chairperson from 1996 to 2004, a stretch that put her at the center of the company’s direction.

Even after stepping down in 2004, Thermax remained the core of her wealth story. Meher Pudumjee succeeded her as chairperson, while hired executives manage the firm. Forbes also notes that consumer goods billionaire Harsh Mariwala has a board seat at Thermax. Another notable move was a partnership with Andrew Forrest’s Fortescue Future Industries to set up a green hydrogen venture in India. Alongside business, Aga cofounded Teach for India in 2008 and later served as a nominated member of parliament.

Forbes net worth trend

Forbes has shown large swings in Aga’s fortune over time, reflecting the value of her Thermax stake. It estimated her wealth at $1.4 billion in 2018, then $1.1 billion in 2019. The number later moved higher, reaching $1.9 billion in 2022 and $2 billion in 2023. Because Thermax is a listed company, changes in market value can have a direct effect on how Forbes measures the worth of a major shareholder like Aga.

The sharpest jump in the figures listed here came when Forbes raised its estimate to $3.3 billion in 2024. By 2025, that figure was $2.9 billion, and Forbes placed her at $2.6 billion in 2026. Forbes currently shows $2.6 billion on its real-time billionaires tracker as of October 20, 2026. The main engine behind those changes is still the same: her majority holding in Thermax and the market’s view of that engineering business.
