Important: These figures are for illustrative purposes only and do not constitute financial advice. Actual returns will vary depending on market performance and individual investment choices. Past performance is not a guide to future performance. Trade fees are based on the number of trades per month entered and may vary by provider. Additional charges may apply — including fund AMC charges — always check each provider’s website for their full, up-to-date fee schedule before investing. If you are unsure whether an investment is right for you, please seek advice from an FCA-authorised financial adviser. The value of investments can go down as well as up. Capital at risk.
What is Fund AMC? Every provider shows a Fund AMC (varies by fund) in their fee basis. This is the Annual Management Charge set by the fund provider (e.g. Vanguard, BlackRock) — not by the platform. It is charged on every fund or ETF you hold, regardless of which platform you use, and is deducted directly from your fund value so you never see it as a separate line item. Typical AMC rates range from 0.07% for passive index funds to 0.75% for actively managed funds. Because this cost is identical across all platforms for the same fund, it does not affect the comparison above — but it will reduce your actual returns on top of the platform fees shown. Always check the individual fund’s factsheet for its exact AMC before investing.
