Stakeholder Note - if you are contributing to an FSAVC (or AVC, or are simply eligable to do so), you can probably contribute to a Stakeholder instead or as well, contributing up to an extra £3600 a year.
(1) - Income is total income, not simply the definition used by the company scheme. Many company schemes define pensions only in respect of BASIC salary, and take no account of bonuses, cars, overtime etc. This means that to retire on say, 50% could be 50% of £10,000 basic income, ( ie £5000), not 50% of the £20,000 that you actually earn taking into account bonuses and overtime etc.
