Should I Opt For A DIY Or Ready-Made Portfolio?

If you’re not confident in making investment choices yourself, then the ready-made option may be best for you.

However, in addition to paying a platform fee, you may also be charged a fund management fee, which is usually a flat fee or a percentage of total investment that year.

It’s worth noting at this point that ready-made portfolios often offer a special plan where you only invest in companies that care about the environment and society also known as ESG investing.

If you know exactly what companies you’d prefer to invest in, then the DIY option would be better for you, and give you complete control over your investments.

How Much Money Can I Make With A Stocks And Shares ISA?

The extent to which your money will grow in a Stocks and Shares ISA depends entirely on what companies you invest in and market conditions.

Financial institutions do their very best to predict how much profit a stock or share will make in the future. But we’re going to level with you here.

You can’t predict everything, and there’s always a chance that you could lose all the money you invest in a Stocks and Shares ISA.

However, if you invest your money in a relatively wide range of stocks and shares, and keep the money there for several years, then there’s a good chance that you will make at least some money from your investments.

It’s important to note at this point that different ISAs are capped at different limits. The £20,000 is a limit on what you can pay in each tax year, not on how much your investments can grow. There’s no cap on tax-free growth inside the ISA.
