Here’s how to try and build a £2m ISA with £30 a day
Opening a Stocks and Shares ISA with a UK brokerage is simple. Most providers let us set up an account online in minutes. All we need is our National Insurance numbers and bank details.
Once set up, a would-be investor can simply choose a monthly contribution. For this example, I’m using a larger contribution than normal: £30 a day, or about £900 a month. That’s not a small sum for everyone, but it’s a figure that can truly go wild when compounding gets involved.
The power of compounding
Investments snowball over time. This is called compounding. And when investing £900 a month, and achieving an annualised growth rate of 10%, this impact is truly significant over 30 years.
At the end of the first year, an investor would have £11,309 in the portfolio. By year five, that’s already £69,693. Fast-forward to year 15, and the portfolio is at £373,023. By year 24, it’d cross the £1m mark, and after 30 years, the ISA could exceed £2m.
| Year | Total deposits | Accrued interest | Balance |
|---|---|---|---|
| 1 | £10,800 | £509 | £11,309 |
| 5 | £54,000 | £15,693 | £69,693 |
| 10 | £108,000 | £76,360 | £184,360 |
| 20 | £216,000 | £467,432 | £683,432 |
| 24 | £259,200 | £811,522 | £1,070,722 |
| 30 | £324,000 | £1,710,439 | £2,034,439 |
Playing the smart game
By investing regularly, rain or shine, investors can harness pound-cost averaging. This essentially means making investments throughout the year to smooth out market bumps and potentially lowering the average purchase price over time. It’s also a disciplined, stress-busting approach that removes the guesswork of market timing.
What’s more, compounding isn’t just a numbers game. It’s a psychological one. The hardest part is sticking with it, especially when markets wobble.
But the really wild part? Most of that £2m fortune would come from growth, not what the investor puts in. In this scenario, after 30 years, an investor would have invested £324,000, but over £1.7m of the total could be pure growth. That’s the magic of letting time and discipline do the heavy lifting.
Capital preservation
However, investors can lose money, especially if they make poor decisions. The key to success is building a strong and diversified portfolio based on capital preservation. That doesn’t mean buying boring businesses or bonds. It just means ensuring there’s a margin of safety and not making a speculative investment.
One stock I believe would complement a varied portfolio is Salesforce (NYSE:CRM). The enterprise solutions giant looks set to play a leading role in agentic AI. These are autonomous systems capable of independent action and decision-making, operating as ‘AI agents.’
What’s more, the valuation isn’t particularly demanding. With a price-to-earnings-to-growth (PEG) ratio of 1.39, it trades at a 37% discount to the information technology sector average. This suggests there is some margin of safety.
However, there is some weakness in its enterprise solutions growth. This is no longer a period of hyper growth. And that could be an issue if Salesforce’s agentic AI push doesn’t take off.
Nonetheless, there’s lots of compelling evidence that Salesforce can lead in agentic AI. First among those is the CEO’s admission that AI conducts 30% to 50% of the company’s workload. It’s practicing what it preaches.
It’s a large part of my portfolio and I believe it’s certainly worth considering.
