Managing personal finances with confidence can more than double a household net worth regardless of earnings, according to research from savings and investing app Moneybox.
The study of more than 4,000 UK adults found that individuals who feel in control of their money hold an average net worth of £228,000, compared to £74,000 for unconfident savers.
Brian Byrnes, 39, personal finance expert at Moneybox, said five simple lifestyle habits taking just 30 minutes a week helped him build tens of thousands of pounds in wealth over the past decade.
"Our research shows that money isn’t the only thing that compounds. The benefits of spending time on your finances can compound too," Byrnes said. "Making one good financial decision can give you the confidence to make another. Over time, those decisions can significantly add up."
The survey assessed consumer confidence across four key categories: saving, investing, retirement planning, and managing personal finances.
The findings come as UK households face rising living costs following a summer of holiday, day-out, and childcare expenses. Energy bills are on course to soar by 25 per cent in January, while households could face tax hikes in the upcoming Budget as Chancellor John Healey seeks funding for Labour spending plans.
Listing financial terms on a phone
Opening savings accounts often exposes consumers to confusing terminology, including terms like compound interest, annual percentage rate, and equities.
During his 20s and early 30s, Byrnes maintained a rolling list on his phone of unfamiliar financial terms, such as "what is an Individual savings account (Isa)?" and "how does pension tax relief work?".
He set aside time every weekend to research each topic, noting that spending a couple of hours dramatically improves financial literacy and estimating that this single habit boosted his savings by thousands of pounds.
Moneybox stated that financially confident households are more likely to set long-term goals and research products, such as finding cash Isas with the highest interest rates.
For example, placing £1,000 in a savings account paying 1 per cent interest yields £1,051 after five years. Choosing an account paying 5 per cent interest yields £1,283 over the same period, providing an extra £232.
After mastering basic terms, savers can research more complex products like pension annuities or investment trusts, or review financial news on Sunday mornings.
Byrnes built a reference collection of blogs, news sources, and podcasts to expand his financial knowledge. "The more time you put in, the more confident you will feel," Byrnes said.
Free guidance is available through government-backed services like MoneyHelper or charitable organisations such as Citizens Advice.
Writing out financial goals
Long-term ambitions such as home upgrades or family holidays can slip away without a structured financial strategy. Setting concrete timelines and expenditure targets helps keep savings plans on track.
Byrnes writes out his short, medium, and long-term financial goals using pen and paper, assigning a specific target figure and completion date to each objective.
Savers can then calculate required monthly contributions. For instance, purchasing a £4,000 second-hand car in two years requires saving approximately £160 a month in an account paying 4 per cent interest.
"There will always be unforeseen events that can set us off course, but having that end goal in mind is the best way to ensure that you are always moving in the right direction," Byrnes said.
Reviewing monthly expenditure
A monthly budget forms the foundation of financial planning, but it requires regular ongoing reviews to track where income is spent.
Mapping out monthly expenditure helps savers identify essential costs and pinpoint unnecessary spending.
"Make a monthly budget and review it regularly. If you find that your spending patterns have changed or your disposable income has increased or decreased, make sure you understand why," Byrnes said.
For example, spending an extra £150 a month on dining out amounts to £1,800 a year in cumulative spending. Savers can adjust habits by preparing work lunches or reducing restaurant visits from weekly to fortnightly.
Micro-investing spare change
Stock market investments historically generate higher long-term returns than cash savings accounts.
Data from Lloyds Bank shows that £1,000 invested in global markets via the S&P World Index over ten years grew to £2,817. The same amount held in one-year fixed savings accounts reached £1,262, representing a difference of £1,555.
However, Moneybox found investing is the area where households feel least confident, with only 40 per cent of survey respondents feeling confident about market investments due to capital loss risks.
Byrnes uses micro-investing to overcome investment apprehension, depositing small weekly sums into financial markets rather than large lump sums. He estimates the technique added tens of thousands of pounds to his net worth.
"Investing a large sum is far scarier if you haven’t built up your investing confidence along the way. It’s easier to invest a couple of pounds a week," Byrnes said.
In 2018, before joining Moneybox in 2022, Byrnes started investing £25 a week using card round-up tools. These tools round everyday transactions to the nearest £1 and invest the difference, such as investing 40p from a £3.60 coffee purchase into a stocks and shares Isa.
Similar round-up features are available through Monzo and True Potential, while providers including Trading 212, AJ Bell, and Fidelity allow monthly direct debits of £25 or £50.
Investing £25 a month over ten years can build a total of £4,604, assuming an average investment growth rate of 8 per cent.
Analysing workplace pension contributions
Byrnes admitted he was disengaged with retirement savings until age 30, contributing the bare minimum of £30,000 across his 20s.
Workplace pension automatic enrolment was introduced in 2012, setting minimum standard contributions at 5 per cent for employees and 3 per cent for employers.
After examining his payslip to understand pension mechanics, Byrnes increased his contributions and grew his total pension pot to nearly £300,000, compared to an estimated £80,000 if he had maintained basic payments.
While many savers assume £1 contributed equals £1 in retirement, compound interest, tax relief, and employer contributions make £1 saved worth roughly £10 in later life.
Under net pay workplace pension schemes, contributions are deducted before tax, giving basic-rate taxpayers 20 per cent tax relief, higher-rate taxpayers 40 per cent, and additional-rate taxpayers 45 per cent.
A £100 pension contribution costs a basic-rate taxpayer £80. Under relief at source schemes, tax relief is added after tax, with higher and additional-rate taxpayers claiming remaining tax relief via the government website gov.uk/check-income-tax-current-year.
"Understanding that the contributions I put in were before tax and were topped up by my employer gave me the confidence to put in as much as I could," Byrnes said. He now contributes between 15 per cent and 20 per cent of his income, including matched employer contributions.
