An investment expert has warned pensioners that they could be missing a simple trick to boost their retirement income. Mark Hartley, an IT professional with a background in financial technology, says that investing just £300 a month in stocks could be more lucrative than a second home for some. Second homes have often been seen as an effective vehicle when planning for retirement but Mr Hartley believes that investing in stocks and shares can deliver a snowball effect that could outstrip the state pension.
The Power of Compounding
He wrote: “Investing regularly in the stock market harnesses the power of compounding — your gains generate their own gains, creating a snowball effect over time. A large enough pot of dividend-paying shares can deliver passive income that exceeds the UK State Pension.”
The key is consistency. Even modest monthly contributions can grow substantially over decades, especially when reinvested dividends buy more shares, which then pay more dividends.
Current State Pension Amounts
The current full new State Pension is £241.30 a week for the 2026/27 tax year, which equates to around £12,548 a year. The full basic State Pension — for people who reached State Pension age before the new system — is £184.90 a week. However the amount someone actually gets can be lower or higher depending on their National Insurance record and any protected/deferred pension entitlement.
The state pension normally rises every April under the triple lock, which increases payments by the highest of inflation, wage growth or 2.5%.
Tax Concerns for Pensioners
The gap between the full new state pension and the personal allowance has narrowed sharply, raising fears that more retirees will be pulled into the tax system. Frozen income tax thresholds mean pensioners can face higher tax bills even when their real income has not increased significantly.
How to Beat the State Pension
Mr Hartley added: “To beat the full new State Pension, you’d need £241.30 a week, or £12,547 a year. Using the 4% withdrawal rule, that requires around £315,000 invested.
“The MSCI World index has delivered an average annual return of 8.9% over the past 40 years. At that rate, investing £300 monthly compounds to £314,688 in 24 years and five months.
“So even someone aged 43 today could beat the State Pension by retirement with just £300 a month.”
