For most people the state pension is seen as a top up to their other pension or income. Whether you could comfortably live off the state pension will depend on certain factors such as whether you own your home, whether you have any financial responsibilities or dependants. The maximum amount you can receive is £164.35 a week, giving you an annual pension of £8,546.20.
Therefore, if you are a married couple this would give you a combined annual pension of £17,092.40. Whether you receive the maximum state pension will depend on how much National Insurance you have contributed. The amount you require in retirement will also depend largely on the type of lifestyle you are used to i.e. new car, 2-3 holidays a year, health club membership, shopping allowances etc.
