Comparing the cost of investing on platforms can be tricky, which is why we put our tables together. There are lots of platforms to choose from, each with their own unique charging structure.

Some obvious points before we start: firstly, some platforms charge a fixed, rather than a percentage fee. This is good for those with a larger lump sum to invest, but can be expensive if you are starting out or have little to set aside.

Secondly, platforms charge a fixed fee each time you buy and sell shares. However, some will also offer a reduced rate if you commit to investing a regular monthly amount (often known as a regular investing plan).

Lastly, cost is only one aspect of choosing a platform. Other factors to consider are how much help you require choosing your investments; how much value you put on investing with a big brand platform and how easy the company’s website is to use.


The table below looks at a £50,000 investment into a pension, where a customer invests only in funds. It highlights the total cost of using the platform over one year.

The calculations include the platform fees, any additional charges for a pension or Isa, and trading charges where applicable.

The first example assumes no trading, the second assumes a customer making six transactions (buys or sells) in the year.

Monthly fund investment in an ISA

This table assumes a monthly investment in a fund, held within an Isa. One set of calculations assumes no trading, whereas the second assumes the customer makes six transactions (either buys or sells) throughout the year.

For simplicity, when calculating percentage charges, we take the mid-point of one year of investing. For example, for £100 a month, we use £600, and for £1000 a month, we use £6,000.

The two tables below use the same assumptions as above, except they assess the cost for investing in equities rather than funds. 

By equities we mean investment in shares, investment companies and exchange traded funds.

The lang cat recently undertook a large research project looking at the cost of using Investment Companies on different platforms. The research was carried out on behalf of the Association of Investment Companies. Click here to have a look at this research


They are a type of fund where investors pool their money to invest in a portfolio of assets, such as shares bonds and cash. A professional fund manager decides what to buy or sell – much like a managed fund.  However, they are listed companies and can be traded like any other share, like Vodafone or National Grid.

As listed companies, they have independent boards of directors to look after shareholders’ interests.
