How much interest on 50 million pounds can I earn?

The interest on 50 million pounds would enable you to live comfortably for the rest of your life without ever having to tap into your capital. 

Let’s explore just how much interest a substantial sum like £50 million can earn for you annually, as well as other ways that you might invest your money to earn better returns.  

The base interest rate in the UK is currently 5.25%. This means that your £50 million could earn £2.62 million in interest annually.

Unfortunately, you cannot simply walk into a bank, deposit £50 million and expect to get 5% interest as most UK banks that offer savings accounts have a deposit limit and an interest rate limit cap.

It’s also important to bear in mind that the Financial Services Compensation Scheme (FSCS) only offers protection for up to £85,000 on an individually owned account.

Challenger banks may have shaken up the banking industry with higher rates, but you would have to investigate other avenues, such as private or investment banks if you wanted to earn interest off £50 million.

Do you pay tax on savings interest?

When you're dealing with significant sums like £50 million, the taxman will come knocking. 

Tax on savings interest is income, and like most other forms of income, it attracts a tax liability.

Unfortunately, individual savings accounts (ISAs), with their yearly tax-free contribution limit of £20,000, do not offer much relief from the potential tax burden on your interest income at this level. 

Earning interest on such a large sum of money can have huge tax implications, so it's always a good idea to consult a financial adviser for personalised advice on managing such a large sum of money.

What is the best way to invest 50 million pounds to earn better returns? 

Let's shift our focus to broader investment horizons with potentially better returns.

Beyond traditional savings accounts, what you can do with £50 million is almost limitless. 

Here are a few recommendations:

  • Luxury investments like a yacht, fine art, or jewellery not only bring joy but can rise significantly in value, acting as both investments and lifestyle enhancements.

  • Investing in real estate is a time-tested option for wealth preservation and growth. Residential or commercial properties can provide consistently high returns over the long term.

  • Explore entrepreneurial opportunities such as investing in or starting a business. This can yield significant returns, albeit with a higher level of risk. 

  • Invest in carefully researched individual stocks with high growth potential or dividend-paying stocks for income and potential capital appreciation.

  • Consider investing in financial instruments such as structured products like derivatives or high-yield bonds like corporate or emerging market bonds.

Bear in mind that higher returns often come with higher risks.

It's crucial to consider your risk tolerance and diversify your investments to strike a harmonious blend of steady, low-risk returns and ventures with the potential for greater rewards.
