When planning pension funding, inflation is often acknowledged but not always fully reflected in contribution decisions. Using an average inflation rate of around 5% over recent years helps to illustrate why this matters so much. Even when inflation appears to be easing in the short term, its long-term effect on retirement income can be significant.

Inflation erodes purchasing power. A pension pot that looks comfortable today may buy far less in real terms by the time retirement arrives. At an average inflation rate of 5%, prices double roughly every fourteen years. This means that someone planning to retire in twenty years’ time will need close to twice the income they might intuitively expect, just to maintain the same standard of living. Ignoring inflation risks building a pension fund that appears adequate on paper but falls short in practice.

Inflation also affects investment returns. Pension growth is often discussed in nominal terms, but what really matters is real growth, that is growth after inflation. A fund growing at 6% per year sounds healthy, but if inflation is averaging 5%, the real increase in value is modest. This has implications for asset allocation, contribution levels and the balance between growth and lower risk investments as retirement approaches.

For those making regular contributions, inflation should influence both the starting level and how contributions increase over time. Flat contributions that are not reviewed regularly lose real value year by year. Linking contribution increases to inflation or at least reviewing them periodically in light of inflation trends, can make a material difference to the eventual outcome.

Finally, inflation uncertainty reinforces the importance of flexibility. Retirement may last twenty or thirty years, during which inflation will vary. Building in a margin of safety, through higher contributions or diversified investments, can help protect against prolonged periods of higher inflation.

Taking inflation seriously is not about pessimism. It is about realism. Factoring an average inflation rate of 5% into pension planning leads to better informed decisions and a greater chance that retirement income will meet expectations when it is most needed.

Automatic enrolment for workplace pensions has helped many employees to start making provision for their retirement with employers and government also contributing to make a larger pension pot.

The law states that employers must automatically enrol workers into a workplace pension if they are aged between 22 and State Pension Age, earns more than minimum earning threshold. The minimum threshold is currently £10,000 and will remain the same in 2026-27. The employee must also work in the UK and not already be a member of a qualifying work pension scheme. Employees can opt-out of joining the pension scheme if they wish.

Under the rules, employers are also required to offer their workers access to a workplace pension when a change in their age or earnings makes them eligible. This must be done within 6 weeks of the day they meet the criteria.

Under the automatic enrolment rules the employer and the government also add money into the pension scheme. There are minimum contributions that must be made by employers and employees.

Both the employer and employee need to contribute. There is a minimum employer contribution of 3% and employee contribution of 4%. This means that contributions in total will be a minimum of 8%: 3% from the employer, 4% from the employee and an additional 1% tax relief. For example, if you pay £40, your employer adds £30, and you receive £10 in tax relief, a total of £80 goes into your pension.

In most automatic enrolment schemes, employees make contributions based on their total earnings between £6,240 (the lower qualifying earnings limit) and £50,270 (the upper qualifying earnings limit) a year before tax. This means that for many employees the 8% contribution rate will not be based on their full salary.
