Inflation: Why price rises are worse for some people than others

The cost of living is more than 11% higher than it was a year ago, the official figures say. But you may feel your bills have risen by a lot more.

That's because your own personal inflation rate is driven by factors specific to you: if you're someone who buys a lot of petrol, your weekly outgoings will have gone up a lot more than someone who cycles everywhere, for example.

Here are some ways that your individual experience of price rises may be at odds with what's reported in the news.

Inflation is measured by taking a typical "basket" of goods and services and seeing how much they're going up in price.

The contents of that basket changes each year as habits change. Pet collars, sports bras or canned pulses on your shopping list? The Official for National Statistics (ONS), which is responsible for calculating inflation statistics, says you're on trend for 2022.

Note: in the calculator, the ONS compares your personal inflation rate with CPIH, a measure of inflation that includes housing costs for those who own their home. Recently this has been slightly lower than the more widely-reported measure, called CPI, and in October 2022 it was 9.6%.

In the age of hybrid work however, suits are out, and blazers, for the more sporadic trip to the office, are in instead. Individual bakery doughnuts are also out, because people working from home are more likely to plump for multipacks instead apparently.

Not everything you buy is reflected in the official inflation numbers; the more niche, the less likely it is to be monitored. And the things you're buying may go up in price by more than what's in the basket, or if you're lucky by less.

It's not just what's in the ONS's basket that's re-evaluated at the start of every year - but how big a part that item plays in our day to day spending. Every item has a "weight" attached, so the changing price of petrol will have a much bigger impact than if the cost of tea goes up - simply because we spend a much bigger proportion of our income on petrol.

Sometimes that means there's a bit of a lag. For example, at present, the ONS assumes that household energy bills make up about 3.5% of spending, which was accurate at the start of 2022. But with energy bills poised to at least double, they're ultimately going to take up 7% or more of a typical household budget. That means the official rate of inflation may not be fully reflecting the impact of rising energy bills until next year.

Inflation has been driven largely by higher energy costs over the last year - but bills vary widely from household to household.

For the 86% of UK homes that are mainly heated by gas, bills have risen more sharply, than where heating is from oil or electricity.

Fuel efficiency makes a big difference too. Homes are rated on energy performance, from A to G, with A being the most efficient. Average fuel costs for a home in England with a D rating are a fifth higher than for those with an A-C rating. Those with a G rating may pay three times as much; those lofty but draughty period homes come with an invisible extra price tag.

Between 2014 and 2021, the ONS reckons inflation was pretty much the same for people in all income groups.

But that's changed this year, because the main items that are rising in price are staples: food as well as energy. That has a bigger impact on those with the lowest incomes. The ONS reckons energy, food, and drink accounts for around 15% of lower-income households' spending, compared to 10% for high-income groups.

It means that it reckons inflation in October was 12.5% for the poorest 10% of households versus 9.6% for the richest 10% - the biggest gap since 2009.

Even if that draughty mansion is expensive to heat, that might not represent as big a problem to the owner as a person on a low income in a small flat.

Older, larger homes will cost more to heat, but the occupants may also be able to better afford the rising bills

But it could have been even worse without the government's Energy Bill Support package. Before it was unveiled, the Institute for Fiscal Studies had predicted least well off households could have faced an 18% inflation rate in October, while the richest 20% could have seen a rate of 11%.

Even if prices are rising for everyone, the pain felt varies. And the only way to maintain living standards is to have more money coming in.

The average pay packet is failing to match the rising cost of living; the gap between the two is the biggest for at least two decades. The private sector - in particular hospitality, where staff shortages have been acute, and financial services - have typically seen bigger pay rises than the public sector. Those relying on the state pension or Universal Credit may see those rates go up by 10% - but they'll have to wait for next spring.

So if you feel your money goes far less far than a year ago you're far from alone.
