See All Articles on Investing    Download Code and Data

AMAZING LINEAR REGRESSION FINANCIAL USE CASES
  • Monthly expenses growth
  • Estimated home loan closure date
  • Estimated portfolio growth in "Current Value (in INR)" per day.

I was getting great ideas on how to name it and one such name was: Linear Regression Comes to Your Financial Rescue :D

You can find the code and data (original and unmasked) in my GitHub Repo. 

But here let's take a look at the findings:

I: Monthly expenses growth

Visual...

Note the spikes in the chart around 2022-23: these were times I made lumpsum payments towards real estate and renovation.

Excel Formula to Crunch The Numbers...


"Ignoring unusually large expenses (₹300,000 or more), how quickly are my monthly expenses increasing or decreasing over time?"
**Filter out rows with expenses exceeding 3L
Robust trend (with filter and without logs):
=ROUND(SLOPE(FILTER(C2:C200,C2:C200<300000),FILTER(B2:B200,C2:C200<300000)),3)

And this number stands out at: 1111.386
Meaning my monthly expenses are increasing at a rate of ₹1,111.39 per month (on average) over the last 5+ years.

II: Estimated Home Loan Closure Date

Loan Repayment Trend Line as of March 23, 2026
Loan Repayment Trend Line as of August 6, 2026
Date Slope (balance change per day) Intercept Estimated Loan Completion Date
2026-MAR-23 -715.21 4881572.37 2041-03-27
2026-AUG-06 -713.91 4880959.87 2041-04-07

III: Investment Growth

Drops in Current Value

(1): Note the drop around mid of 2025: That was when I repaid my car loan. (2): And the drop around mid of 2026: That was when I repaid my personal loan.

And the good news is...

My portfolio is growing at a rate of ₹936 per day (on average) over the last 2-or-so years. ** As per the old and wise Owl named 'Linear Regression' **

And let me admit: rather having much to do with mathematical modeling, all three of these use cases have got an awful lot to do with financial discipline with money and patience to watch the numbers move tiny bit after weeks, months and years of data accumulation.

Tata Trusts’ Pivot: From Funding Projects to Building Institutions

See All Articles


5 Key Takeaways

  • Tata Trusts will shift from funding short-term projects to creating durable institutions in healthcare and education.
  • Plans to build 40-50 not-for-profit general hospitals with a cross-subsidy model ensuring uniform care for all.
  • Advocates regulatory reforms to encourage private investment in higher education and build world-class institutions.
  • Calls for measurable, concrete outcomes in philanthropy instead of vague feel-good metrics.
  • The guiding philosophy is 'Do what India needs,' prioritizing excellence and long-term institutional building over size.



"Do What India Needs": Tata Trusts Charts a Return to Institution-Building

Noel Tata unveils an ambitious plan to build 40–50 not-for-profit hospitals and a new generation of academic institutions, demanding measurable accountability from Indian philanthropy.

In a sweeping address that signals a major strategic shift for one of India's oldest philanthropic institutions, Noel Tata, Chairman of Tata Trusts, revealed that the organisation will move decisively beyond its traditional role of funding projects and non-profits. Speaking at the IIMBue 2026 annual conclave in Bengaluru on August 2, 2026, he outlined an ambitious roadmap focused on building permanent institutions in healthcare and education, while demanding a new era of accountability in Indian philanthropy. The vision amounts to a revival of the founding impulse that gave India some of its most cherished public institutions over a century ago.

A Legacy of Nation-Building, Not Business Dominance

Tata Trusts is the philanthropic arm of the sprawling Tata Group, but Noel Tata made it clear that the group's ultimate purpose was never commercial scale. He reminded the audience of the foundational message passed down by the founders who bequeathed their company shares to the Trusts.

"The founders left their shares in the companies to the Trusts with one message: do good for India. They never said to become the biggest company. The companies exist to serve India and improve the quality of life."

That guiding principle, often overshadowed by the sheer size of the Tata Group's businesses, is now being placed back at the centre of the Trusts' strategy.

The historic result of that philosophy is a roster of institutions that have shaped modern India: the Indian Institute of Science, the Tata Institute of Fundamental Research, and the Tata Memorial Hospital, to name just a few. These were not quick-impact projects that folded after a few years. They were designed to serve generations. Tata Trusts now wants to return to that original template, moving from supporting existing organisations and short-cycle development programs to creating durable, world-class institutions that outlast any single grant cycle.

Building a National Healthcare Infrastructure

The most concrete manifestation of this shift will be in healthcare. Noel Tata announced that Tata Trusts will establish between 40 and 50 not-for-profit general hospitals across India. These will not be boutique facilities for the wealthy. Instead, they will operate on a cross-subsidy model. Patients who can afford to pay premium rates will, through their payments, help underwrite the treatment of patients from economically weaker sections. Crucially, the quality of doctors, medicines and overall healthcare infrastructure will remain uniform across the paying and subsidised streams. No patient will receive a second-class standard of care simply because they cannot pay.

The design is intended to solve a persistent problem in Indian healthcare: the deep segregation between high-end private care and a strained, under-funded public system. By creating a network of hospitals that runs on a professionally managed, self-sustaining yet not-for-profit business model, Tata Trusts hopes to demonstrate that affordable, high-quality care can be scaled nationally without depending perpetually on donor funds or government budgets alone.

Education as the Second Pillar

Education forms the other half of the new institutional push. Noel Tata described a forthcoming undergraduate institution being developed in partnership with the Indian Institute of Management Bangalore as an important beginning, but his vision extends much further. He argued that India suffers not from a scarcity of academic talent, but from a severe shortage of institutional infrastructure capable of attracting and retaining it. As evidence, he pointed to the large numbers of Indian-origin professors teaching at the world's greatest universities, including Harvard. The talent is there; the platforms to bring them back or keep them at home are not.

India's annual loss of thousands of brilliant students to foreign universities, he said, is largely a problem of inadequate domestic capacity, not a failure of ambition. "There is no reason why India cannot build enough quality institutions so students can study in India instead of leaving simply because there are too few seats," he stated. To make that possible, he advocated for regulatory reforms that would encourage greater private investment in higher education. Current restrictions on for-profit educational institutions, he noted, have inadvertently discouraged serious, long-term capital from entering the sector. Changing those rules, he believes, is essential if India is to construct enough world-class classrooms, laboratories and research centres in time to capture its demographic dividend.

A New Kind of Accountability

Perhaps the most pointed part of his address was a call for philanthropy itself to become more rigorous. Speaking to an audience that included many alumni who now occupy influential positions, Noel Tata did not spare charitable organisations from scrutiny. He argued that the sector is overdue for a shift away from vague, feel-good metrics toward hard, measurable outcomes.

"When someone says we have touched thousands of lives, my question is: what does 'touched' actually mean? We need measurable outcomes. We need to know what difference our spending has actually made."

This demand for evidence of impact is as much a self-critique as a challenge to the broader philanthropic ecosystem. Tata Trusts, with its vast resources and long history, intends to set a standard by publicly demonstrating how its rupees translate into verifiable improvements in health indicators, educational attainment or other concrete social gains.

This push for accountability comes at a moment of generational change in Indian giving. Noel Tata noted that the country's philanthropic landscape is being transformed by a wave of entrepreneurs who are committing substantial personal wealth to social causes. "Every day I come across people who want to give back to society. It is inspiring and it also puts pressure on older institutions like ours to become more effective and accountable," he observed. The new entrants are often demanding sharper clarity on results, and the established players cannot afford to lag behind.

The Corporate Legacy that Shapes the Philanthropy

Noel Tata's personal experience as a business leader heavily informs his approach to the Trusts. He recalled how many of the Tata Group's most enduring businesses were created not as stand-alone commercial deals, but as deliberate responses to national developmental gaps. Tata Motors, for instance, grew out of manufacturing locomotives before expanding into commercial vehicles when India needed them. Tata Power came into existence to generate electricity at a time when Indian industry still relied overwhelmingly on steam power. He encapsulated the entire organisational philosophy with a maxim attributed to former Tata Group chairman Jehangir Ratanji Dadabhoy Tata:

"Do what India needs."

— J.R.D. Tata

That phrase now operates as a lens through which the Trusts are reviewing their own priorities. Instead of asking "which NGO should we fund this year?" the question becomes "what permanent capacity does India lack that we can help build?" It is a multi-decade commitment, not an annual budgeting exercise.

Noel Tata also shared a revealing story from his own corporate journey. After the Tata Group exited the Lakme cosmetics business in the late 1990s, he was instrumental in creating Trent Limited, the retail company. The strategic decision was to build Trent around private-label brands rather than chase rapid topline growth by stocking third-party labels. For years, the company faced criticism for its deliberately slow pace of expansion. But the discipline paid off, and Trent eventually emerged as a potent force in Indian retail. The lesson, he said, is universal:

"My philosophy has always been to be the best in everything you do. If you become the best, size follows. Trying to become the biggest without first becoming the best can end in disaster."

That distinction between the pursuit of excellence and the pursuit of size now animates the Trusts' new direction. Building 40 to 50 hospitals that deliver genuinely top-tier care to all economic segments is the harder path. Developing an undergraduate institution recognised globally for its rigour, rather than simply adding another campus to an overburdened system, will take years. The same holds for demanding measurable social impact instead of counting heads. The entire vision is a bet on depth rather than spread.

From Making Money to Spending It Well

For Noel Tata personally, the shift from corporate leadership to heading Tata Trusts has been a profound one. He described the transition succinctly: "You stop trying to make money and start trying to spend it." But his remarks made it clear that effective giving is in many ways more demanding than running a business. In the social sector, one is confronted directly with the magnitude of the challenges ordinary citizens face. The responsibility of ensuring that every single rupee creates meaningful and lasting impact is, in his telling, a weight far heavier than any quarterly earnings target.

He spoke of the exposure to ground-level reality that philanthropy forces upon its practitioners. It strips away the abstractions of boardrooms and market reports and replaces them with the tangible difficulties of access, affordability and quality that define the lives of hundreds of millions of Indians. For an institution as storied as Tata Trusts, that is both a humbling reckoning and a call to raise its ambitions.

What Comes Next

The blueprint is now public. In the coming years, India will watch for the first groundbreakings of those not-for-profit hospitals and the inaugural admissions to the new undergraduate institution co-created with IIM Bangalore. It will watch to see whether the regulatory environment for private educational investment shifts in the direction Noel Tata urged. And it will watch whether the Trusts themselves meet the very standard of measurable accountability they have set for everyone else.

This is not a pivot that will produce instant gratification. Institutions cannot be rushed. But if the effort succeeds at anything like the intended scale, it would mark a return to the most consequential chapter of Tata Trusts' history—the chapter that long ago gave the country the Indian Institute of Science and Tata Memorial Hospital. At a time when India's need for high-quality, accessible public goods is more acute than ever, the decision to stop merely funding projects and start building permanent institutions may prove to be one of the most significant statements of intent in the modern history of Indian philanthropy.
