How We Calculate Net Worth
FIF does not invent its own net worth estimates. Every figure on the site comes from a named, published source, with the date it applies to.
Which sources we use
For billionaires we use, in this order of preference:
- Forbes Real-Time Billionaires, updated daily for listed holdings.
- Bloomberg Billionaires Index, updated daily for the world’s richest 500 people.
- Hurun rich lists (Hurun India and Hurun Global), published once a year.
- Other named lists, such as the 360 ONE Wealth Creators List, only where the main three do not cover a person. We say so on the page.
Where two sources disagree, we show both and name each one. Company figures come from annual reports, stock exchange filings (BSE, NSE, SEC) and the company’s own results releases.
Dollars and rupees
Each net worth figure is shown in US dollars with the rupee equivalent in crore or lakh crore. We convert at the Reserve Bank of India reference rate and state the rate and its date on the page. A figure such as “$90.7 billion (about ₹8.56 lakh crore) on 6 November 2026, per Forbes” tells you the amount, the conversion, the date and the source.
What a net worth figure includes
Lists estimate the value of a person’s stakes in listed and private companies, plus cash, property and other assets they can identify, minus known debts. Shares held by charitable trusts are not counted as personal wealth. That is why some heads of large groups have modest personal fortunes.
When we update
- We refresh a figure when it moves by more than 10% or when the person’s rank changes.
- Every profile shows a “Last verified” date. The net worth page keeps a dated history; older figures are never overwritten.
- Rankings on FIF use each person’s latest figure from the last 60 days.
What we do not do
We do not estimate the wealth of people who are not covered by a published list. If no reliable figure exists, the page says so. We do not publish salaries, house prices or quotes without a named source.
