A reference group is the set of people we mentally stand beside when we judge whether our income, spending, or savings feel adequate. They might be colleagues in similar roles, relatives in the same city, neighbours in our building, or even online acquaintances whose lives we only see through curated posts. Research shows that we often choose these groups without much reflection, and we tend to look upward toward people who appear more comfortable than we are. This can make our own situation feel worse than it truly is, even when our essentials are covered. By consciously selecting reference groups that share our income level and obligations, we can create fairer comparisons and reduce unnecessary pressure on our budget.

Relative income refers to how our earnings look compared with those of the people around us, rather than the absolute number on our payslip. Two people with the same salary can feel very different about it if one works among higher paid peers and the other among lower paid peers. Studies across countries have found that satisfaction with income often depends more on this relative position than on the raw figure alone. In practice, this means that a raise may feel disappointing if we learn that colleagues received more, even though our own budget has improved. Understanding relative income helps explain why some financial decisions are driven by status concerns rather than by practical needs.

Status signalling is the use of visible goods or experiences, such as housing, vehicles, clothing, or celebrations, to send messages about our social position or success. In many communities, certain purchases act as shorthand for having reached a particular level of comfort, even when they require significant sacrifice behind the scenes. Social comparison plays a strong role here, because we often choose signals that match or slightly exceed what our peers display. While status signalling can help people feel recognised, it can also encourage overspending, especially when we try to keep pace with others whose incomes or safety nets are very different from our own.

Loss aversion describes the tendency to feel the pain of losing something more strongly than the pleasure of gaining something of equal size. In financial contexts, this can mean we hold on tightly to a certain lifestyle once we have experienced it, even if it strains our budget. When combined with social comparison, loss aversion can make it especially hard to scale back expenses after seeing peers maintain or increase their spending. We may fear the social loss of appearing to fall behind more than we value the financial relief of a simpler routine. Recognising this bias can help us frame changes as gains in stability rather than as humiliating setbacks.

Herd behaviour occurs when people follow the actions of a group, especially under uncertainty, rather than relying on their own information or analysis. With money, this can look like choosing similar housing, schooling, or festival spending levels simply because that is what everyone around us seems to be doing. In social comparison terms, the herd provides a ready made reference point: if most neighbours are upgrading, we may feel pressure to join, even if our numbers do not support it. While following the crowd can sometimes be efficient, it can also amplify mistakes, so it is worth pausing to ask whether the herd’s situation truly matches our own.

Anchoring is the tendency to rely heavily on the first number or example we encounter when making a judgment, even if it is not fully relevant. In financial comparison, the first salary we hear, rent we pay, or wedding budget we see can become a mental anchor that shapes what later amounts feel big or small. For instance, if a friend casually mentions an ambitious saving target, our own more modest plan may suddenly feel inadequate, even if it suits our income. By noticing these anchors, we can adjust them deliberately, reminding ourselves that a single story should not define what counts as reasonable for everyone.

Mental accounting is the habit of dividing money into separate mental buckets, such as rent, groceries, entertainment, or gifts, and treating each bucket differently. Social comparison can influence how large or small we allow these buckets to become, especially for visible categories like dining out or celebrations. If peers seem to spend generously in one area, we may quietly expand that bucket while squeezing others, sometimes without realising the trade offs. Understanding mental accounting helps us see how comparison can distort certain categories, and encourages us to align our buckets with personal priorities rather than with what others appear to prioritise.
