Important: These projections are illustrative estimates only and do not constitute financial advice. Growth rates are not guaranteed and actual returns will vary. The pension net value assumes tax on withdrawals at the basic rate (20%) in retirement; your actual tax position may differ. Pension access is currently restricted to age 55, rising to 57 in 2028. ISA allowances and pension annual allowances apply. You should seek independent financial advice before making any investment decisions.
