Illustration only. Charges are modelled as a simple drag on the annual return. Higher charges are not automatically bad — the question is always what you get for them.
Assumptions and method
- Each scenario compounds monthly at (growth − charge) ÷ 12; contributions added monthly.
- "Total charge" should include everything: platform fee + fund charges + any ongoing advice fee. Firms must disclose aggregated costs if you ask.
- No allowance for tax or inflation; returns are assumed smooth, which real returns never are.
Use this alongside what financial advice costs — it's the tool for converting "0.75% ongoing" into pounds over a decade before you sign anything.
Reminder: general education only — not advice, and not a suggestion that any particular product or fee level is right for you. For personal recommendations, consult an FCA-authorised adviser via our toolkit.
