Question 1

How long does it take to become a millionaire?

Accepted Answer

The time to reach £1 million depends on how much you invest each month and your investment return rate. Investing £500 per month at a 7% annual return takes approximately 33 years. Increase that to £1,000/month and you could reach £1M in around 24 years. The MillionaireAge calculator shows your exact projected timeline.

Question 2

How much should I invest monthly to reach £1M?

Accepted Answer

To reach £1 million in 20 years at a 7% annual return, you would need to invest approximately £2,300 per month. To reach it in 30 years, around £750 per month is needed. If you already have significant savings, the required monthly contribution will be lower. Use our calculator to find your exact number.

Question 3

What return rate do investors typically achieve?

Accepted Answer

Historically, a globally diversified stock market index fund has returned around 7–10% per year before inflation. The S&P 500 has averaged roughly 10% annually over the long term. A conservative estimate of 5–7% after inflation is commonly used for financial planning. Our calculator defaults to 7% as a realistic long-term assumption.

Question 4

Can compound interest really create £1 million?

Accepted Answer

Yes — compound interest is the most powerful force in personal finance. When your returns generate their own returns, your wealth accelerates exponentially. £300 per month invested at 8% annual growth becomes over £1 million in 35 years — with only £126,000 of that coming from your own contributions. The rest is pure compound growth.
