Constructing a big portfolio doesn’t have to interrupt the financial institution. Certainly, investing £1,000 a month may end up in a portfolio value £1.16m after 30 years. That might generate a really sizeable second earnings.
The nice information right here is that this situation assumes a 7% common annual return. That’s truly beneath the long-term whole return from the FTSE 100 and considerably lower than the typical returns of the S&P 500.
Right here’s how I’d go about attempting to achieve a £100k+ passive earnings portfolio.
Get the ball rolling
A no brainer place to begin can be to arrange a Shares and Shares ISA. This may actually open up a world of investing potentialities as a result of most ISA suppliers in the present day enable worldwide dealing.
The profit right here is that it might give my portfolio diversification, permitting me to purchase US shares in addition to these listed in London. My very own portfolio in the present day is cut up about 50/50 between US and UK shares.
Even higher, an ISA permits me to take a position £20k a 12 months and pay no tax on any capital returns or dividends. That’s why I exploit the time period no-brainer.

Which shares to purchase?
Right here, I’m going to focus on a FTSE 100 inventory I’ve at the moment received on my purchase listing. It typically flies beneath the radar regardless of rising earnings impressively for years. It’s Coca-Cola HBC (LSE: CCH).
This Switzerland-based firm has the unique rights to bottle and distribute merchandise from The Coca-Cola Firm in 29 international locations throughout Europe, Asia, and Africa. The HBC bit on the finish stands for Hellenic Bottling Firm, hinting at its roots in Greece within the Sixties.
The agency buys core concentrates, syrups and bases from the US mushy drinks big. These are the formulation that give Coca-Cola, Sprite, and Fanta their particular tastes. In the meantime, Coca-Cola retains a big possession stake within the firm.

In 2023, internet gross sales income elevated 10.7% 12 months on 12 months to €10.2bn, representing the third straight 12 months of double-digit development. Web revenue was €637m and brokers see this rising to €864m in 2026.
The dividend was raised by 19% and its five-year compound annual development charge is 10.3%. The forward-looking dividend yield in the present day is 3.1%, which I discover engaging given its long-term development potential.
Naturally, an financial downturn is a danger right here, as this might result in weaker demand for mushy drinks, particularly within the vacationer hotspots it operates in (Italy, Greece, Switzerland, and so forth).
That stated, Coke gross sales have a tendency to carry up fairly effectively even throughout downturns. Buying and selling at 14 instances ahead earnings for 2024, I feel the inventory provides super worth.
Passive earnings
As talked about, such shares attaining a 7% annual return might assist me construct a £1.16m portfolio in 30 years.
Nevertheless, I feel it’s lifelike to goal for a mean return of 9%. This isn’t assured and there shall be tough intervals alongside the best way, together with maybe the odd main crash. However pound value averaging (investing often so generally I purchase when costs are excessive, generally once they’re low) would assist easy out these ups and downs.
Assuming this 9% return (which, in fact, isn’t assured and might be a lot decrease), my hypothetical £12,000 compounding at this greater charge over three a long time would grow to be £1.7m, excluding any brokerage charges. Beautiful.
At this level, I might select to put money into dividend-paying shares yielding a mean 6%, giving me a possible yearly passive earnings stream of £102,000.
