My one-year-old daughter has a Junior ISA and a SIPP (Self-Invested Personal Pension). These are accounts and tax wrappers that allow us to invest in stocks and shares and leverage the power of compounding for long-term growth. But what about this £37m figure? Well, the maths tells us that it’s possible.
In fact, this is a calculation I’ve run for my daughter’s SIPP:
- A total of £320 in monthly contributions, consisting of £240 from my own funds and £80 from HRMC.
- I’ve accounted for this figure increasing by 3% annually, assuming a rising threshold.
- A 12% annualised growth rate, which is about the rate of growth I think I can achieve for her. Other investors may wish to take a slightly lower figure.
- As of 2028, the minimum age to withdraw from a SIPP is 57 years. So, I’ve accounted for 57 years of investing and reinvesting.
Adding all this together, we come to the figure of £37m. As we can see from the graphic below, most of the growth is coming towards the end of the period. That’s compounding. Compounding really comes into its own when we invest for the very long run. I appreciate this requires a very long-term perspective. But I’m surprised more people don’t do this.

This is how Warren Buffett made it
This isn’t a new strategy. In fact, Warren Buffett‘s wealth is a testament to the power of compounding and time. At age 30, his net worth was $1m, growing to $25m by 39. By 56, he became a billionaire, and by 66, his wealth surged to $17bn. Remarkably, 99% of his wealth was accumulated after age 50, with $84.2bn earned post-50 and $81.5bn after 65. Today, he’s worth $160bn.
Buffett’s strategy of reinvesting profits and focusing on long-term investments allowed his wealth to snowball over decades. For example, his $1bn investment in Coca-Cola in 1988 grew to over $20bn through reinvested dividends. This exponential growth underscores the importance of starting early and letting compounding work over time.
Investing for long-term growth
With Buffett in mind, one stock to consider for long-term investing is his Berkshire Hathaway (NYSE:BRK.B) conglomerate.
Berkshire Hathaway, under Warren Buffett’s leadership, has consistently demonstrated its ability to deliver long-term growth through disciplined investing and compounding. From 1965 to 2023, the company achieved a compound annual growth rate (CAGR) of 19.8%, significantly outperforming the S&P 500’s 10.2% over the same period.
Moreover, its diversified portfolio, spanning insurance, utilities, and railroads, provides stability and resilience across economic cycles. This is why it was one of the first investments in my daughter’s SIPP.
In 2024, Berkshire reported more positive results, supported by strong insurance operations and a $334bn cash reserve. This financial strength allows Berkshire to capitalise on market opportunities, such as its recent investments in Japanese trading houses.
However, risks include its reliance on Buffett’s leadership, with succession concerns looming. Additionally, its massive size may limit agility in volatile markets, although its cash position may suggest the opposite.
Despite these challenges, Berkshire’s proven track record, wide economic moat, and conservative capital allocation make it an enticing proposition for long-term investors. Analysts maintain a Buy rating, with a 12-month price target of $511, reflecting confidence in its continued growth.
