Investing £2,000 per month exceeds the stocks & shares ISA annual allowance (£20,000 ISA + £4,000 in a GIA or pension). At 7% returns over 25 years, this grows to approximately £1,621,000 — with £600,000 contributed and over £1 million generated through compound interest. At this rate, your money is working harder than you are within the first decade. For high earners, business owners, or those who've received an inheritance, this level of investment can build multi-generational wealth. The key consideration at this level is tax efficiency — use your full ISA allowance first, then consider pensions and GIAs.
