Martin Lewis sets out a simple “rule of thumb” for how much people should aim to contribute to their pension, emphasising that starting earlier generally improves retirement outcomes. In a recent appearance connected to the Martin Lewis Money Show, Lewis responds to a question from a viewer who asks whether making 15% pension contributions in their mid-30s is enough without affecting their current quality of life. Lewis says the viewer is “really well” placed with that level. He then explains the method: take the age when you begin pension contributions, halve it, and use that as the percentage of income to direct into your pension for the rest of your working life. For example, if someone starts at 30, the rule suggests 15%. Lewis frames the guidance as a way to show many people may not ultimately reach that contribution level, and as an illustration that the earlier someone starts saving, the better their prospects for retirement. He also notes the advice should be considered alongside the State Pension, which is part of retirement income.
