The £100k Question: Is a Bigger Paycheque Worth a Smaller Life?
💬 Be honest. Would you trade £20k less a year for more time, freedom, and peace of mind?
It’s a question that almost every professional faces at some point. Is earning £100k worth it if it means working 12-hour days, replying to emails late at night, and rarely having the time or energy to enjoy what you’ve earned? Or would you be better off earning £80k with shorter, more flexible hours, even if that means rethinking what success looks like?
This dilemma sits at the intersection of economics, psychology, and wellbeing. It also reflects a cultural shift in how we define success and how we value our time.
In this blog, we explore what the research says about income, time, and happiness. We also look at how flexible work, relocation, and the UK tax system reshape the balance, and why understanding the real value of your time might be one of the most important financial insights of your career.
Redefining Success
For decades, professional success was defined by income, seniority, and status. A six-figure salary was the ultimate marker of having “made it.” But that definition is losing ground.
The pandemic and the rise of flexible work changed how millions of people view success. According to Microsoft’s Work Trend Index, more than 50% of workers globally have re-evaluated their priorities since 2020. Autonomy, flexibility, and mental wellbeing now rank alongside salary as core measures of fulfilment.
A Harvard Business Review survey found that 59% of professionals would accept less pay for better work-life balance. Many cited freedom over their time as a stronger motivator than financial gain. This doesn’t mean money doesn’t matter, but rather that it is no longer the only measure of achievement.
However, the decision becomes more complex in the UK when the tax system and benefit thresholds are considered. Once your income crosses £100,000, the personal tax allowance begins to taper away. For every £2 earned above that level, £1 of your tax-free allowance is lost, creating a 60% effective marginal tax rate between £100,000 and £125,140.
The financial impact doesn’t stop there. Higher earners often lose access to valuable government schemes such as:
Tax-Free Childcare, which provides up to £2,000 per child annually.
30 hours of free childcare for three and four-year-olds, available only to households earning under £100,000 per parent.
Child Benefit, which is reduced once one parent earns over £50,000 and completely withdrawn by £60,000.
When these benefits disappear, the financial edge of earning six figures can shrink dramatically. For some families, a household income of £99,000 may result in a higher net benefit position than £110,000 after taxes and lost entitlements.
In short, the pursuit of a higher salary can sometimes bring diminishing returns once real costs are considered.
Does Money Really Buy Happiness?
Research shows that money does increase happiness—but only to a point.
A famous study by Nobel laureates Daniel Kahneman and Angus Deaton found that emotional wellbeing rises with income up to around £60,000 to £70,000 per year, after which the effect levels off. The study suggested that once basic needs and a moderate level of comfort are met, additional income has little impact on day-to-day happiness.
More recent research by psychologist Matthew Killingsworth challenged that conclusion, suggesting that happiness continues to rise with income but depends heavily on how people use their money. If higher income supports autonomy, security, or purpose, happiness increases. If it simply funds material upgrades, the effect fades quickly.
This aligns with the concept of the Hedonic Treadmill—the tendency to adapt to new levels of wealth and return to a baseline of satisfaction. Each pay rise brings a temporary boost, but soon becomes the new normal, prompting the search for the next increase.
The takeaway is that money contributes to happiness when it buys freedom and reduces stress, not when it replaces meaning or rest.
The Real Trade-Off: Time, Money, and Value
When comparing a high-paying job with a more balanced one, the real difference often lies in how your time is valued.
Take two professionals: one earning £100,000 for a 60-hour week and another earning £80,000 for 35 hours. On paper, the first earns more. But when adjusted for time, the second effectively earns £44 per hour versus £32 per hour for the first. Add commuting costs, stress, and fatigue, and the difference becomes even more striking.
Economists refer to this as opportunity cost—the value of what you sacrifice when making a choice. For many professionals, the hidden cost of higher pay is time with family, health, or peace of mind.
The UK’s tax system adds another layer of complexity. Moving from £80k to £100k can push someone into a higher tax band where the increase in take-home pay might be less than £700 a month. That amount can easily be outweighed by the cost of longer hours, missed experiences, or burnout-related health impacts.
This highlights the importance of calculating your real hourly value, not just your gross annual salary. It’s an exercise that can transform how you view work and compensation.
The Power of Location and Flexibility
One of the biggest shifts of the last decade has been the decoupling of income and geography. Remote and hybrid work have given professionals more freedom to choose where and how they live.
Economists refer to this as geographic arbitrage—earning a city salary while living somewhere cheaper. A London-based professional earning £90,000 could move to Manchester, Edinburgh, or even work remotely from Portugal, cutting housing costs by 30–50% without reducing income.
This flexibility can also change access to government support and quality of life. Living in a region with lower council tax, cheaper housing, and affordable childcare can offset the need for a higher salary. In some cases, relocating or switching to a remote role allows families to reclaim both time and disposable income.
The key point is that “earning less” doesn’t always mean “having less.” By rethinking location and lifestyle, professionals can often maintain financial stability while gaining something far more valuable: freedom over their time.
The Risks of Chasing More
The pursuit of higher income comes with a hidden cost—burnout.
The World Health Organization now classifies burnout as a workplace condition caused by chronic stress. It is linked to anxiety, insomnia, and serious long-term health issues. Research from Stanford University found that productivity per hour declines sharply after 50 hours a week and that working beyond 55 hours adds almost no measurable output.
In financial terms, burnout is a liability. It leads to mistakes, reduced creativity, absenteeism, and even early career exits. For many professionals, the cost of burnout eventually outweighs the rewards of the pay rise that caused it.
Ironically, people often chase higher salaries to improve quality of life, only to find that the long hours and stress undermine it. Recognising when work stops serving your wellbeing is a crucial step in maintaining long-term success.
Redefining Wealth
Wealth is not just about money. It includes time, health, and relationships.
Professionals who consciously trade some income for flexibility often report greater satisfaction and more sustainable careers. Trials of the four-day work week in the UK, Iceland, and Japan found that output remained steady while stress and absenteeism declined.
Behavioural economists describe this as Work–Life Recalibration—when productivity and wellbeing align rather than compete.
In the UK, those earning below key thresholds can also retain access to valuable government support such as childcare subsidies and personal allowances. For families, this can effectively increase net disposable income even without a higher gross salary.
Choosing balance does not mean abandoning ambition. It means optimising for the metrics that truly matter: time, purpose, and fulfilment.
Final Thoughts
The £100k question is not really about money. It is about what your time, peace of mind, and personal priorities are worth.
Economist Tim Harford once wrote that “money is a store of possibilities.” The real choice is which possibilities matter most—the freedom to live well or the pursuit of more income.
There is no universal answer. For some, £100k brings the sense of progress, security, and opportunity they seek. For others, £80k with flexibility and family time feels like true success. The key is to make the decision consciously, not by default.
Understanding how taxes, benefits, and time value interact can help you make more informed choices. When you view your life as a balance sheet of both time and money, you start to see that wealth is not only what you earn, but how well you live.
What Do You Think?
💬 How do you define success in your own life? Would you choose £100k with long hours or £80k with flexibility and more time to yourself?
Perhaps you’ve already made a similar decision, trading income for freedom or vice versa. How did it impact your happiness, finances, or family life?
Everyone’s balance point is different, but hearing how others approach it can help challenge assumptions about what success really means.
Share your thoughts in the comments or start a conversation with your team, partner, or friends. Sometimes the best financial decision isn’t about earning more, it’s about living better.
