Why ₹100 Doesn’t Always Equal ₹100: The Money Illusion That Fools Everyone
Seventeen-year-old Kavya was thrilled when her father came home with exciting news. “I got a ten percent raise!” he announced proudly. “My salary went from ₹50,000 to ₹55,000 per month. We should celebrate!”
The family did celebrate, but a few months later, Kavya’s father seemed stressed about money despite his raise. “I don’t understand,” he told his wife. “I’m earning more than before, but it feels like we have less money. Where is it all going?”
Kavya, who had just learned about inflation in her economics class, realized what was happening. “Papa, what’s the inflation rate this year?” Her father checked online. “About twelve percent,” he read. Kavya pulled out a calculator. “So prices have gone up by twelve percent, but your salary only went up by ten percent. In terms of what you can actually buy—your real purchasing power—you’re earning less than before, not more. You got a ten percent raise in rupees, but a two percent pay cut in what those rupees can buy.”
Her father was stunned. He’d been so focused on the larger number in his bank account—₹55,000 instead of ₹50,000—that he hadn’t considered whether those rupees bought as much as they used to. He’d fallen victim to money illusion—focusing on the nominal (face) value of money while ignoring its real value in terms of purchasing power.
This cognitive trap affects everyone from workers evaluating salaries to retirees living on fixed incomes to governments making economic policy. Understanding money illusion reveals why our financial intuitions often mislead us and why ₹100 today isn’t the same as ₹100 yesterday or ₹100 tomorrow.
What Is Money Illusion?
Money illusion is our tendency to think about money in nominal terms (the number written on bills and in bank accounts) rather than in real terms (what that money can actually purchase). We feel richer when we have more rupees, even if those rupees buy less than our previous smaller amount bought. We feel poorer when we have fewer rupees, even if those rupees buy more than our previous larger amount bought. We focus on the numbers rather than on the purchasing power those numbers represent.
The concept was introduced by economist Irving Fisher in the 1920s and extensively studied by later economists including John Maynard Keynes. Research at Princeton University demonstrated that money illusion affects both individuals and markets. In experiments, people consistently preferred a two percent nominal wage increase during three percent inflation (a real wage decrease) over a one percent nominal wage decrease during zero inflation (a real wage stability)—even though the second option left them better off in purchasing power.
According to studies from Yale University, money illusion occurs because our brains find nominal values (the numbers) easier to process than real values (purchasing power). Calculating purchasing power requires knowing both the nominal amount and the price level, then computing the ratio. Our brains prefer the simpler shortcut of just looking at the nominal number and treating bigger numbers as better, even when inflation has made bigger numbers worth less.
Research from Stanford University shows that money illusion affects financial decisions across domains. People resist nominal wage cuts even when they would accept real wage cuts through inflation. Borrowers feel they’re paying more when nominal interest rates are high even if real (inflation-adjusted) rates are low. Retirees withdraw fixed nominal amounts from savings without adjusting for inflation, gradually impoverishing themselves as purchasing power erodes.
The Farmer’s Harvest and the Clever Merchant
An old Indian folk tale tells of a farmer who harvested one hundred sacks of wheat one year. The next year, favorable rains gave him one hundred twenty sacks—twenty percent more! He celebrated his prosperity, telling everyone about his abundant harvest.
But a clever merchant noticed something the farmer had missed. The previous year, wheat sold for ₹1,000 per sack. This year, because everyone had good harvests, wheat sold for only ₹750 per sack. The farmer’s one hundred sacks had earned him ₹1,00,000 the previous year. His one hundred twenty sacks earned him only ₹90,000 this year. He had twenty percent more wheat but ten percent less money—and with general price inflation at fifteen percent, his purchasing power had declined by about twenty-three percent.
When the merchant explained this, the farmer was bewildered. “But I have more sacks of wheat! How am I poorer?” The merchant gently explained: “You’re counting sacks instead of counting what those sacks can buy. Your bigger pile of wheat is worth less in terms of food, clothing, and tools you can purchase. You’re richer in sacks but poorer in everything else.”
Buddhist economics teachings address money illusion through the concept of confusing symbols with reality. Money is just a symbol representing value, not value itself. Focusing on the symbol (nominal money) while ignoring what it represents (purchasing power) is a form of delusion that the Buddha warned against. True wealth is measured in wellbeing and ability to meet needs, not in accumulating symbols.
The Bhagavad Gita touches on this through Krishna’s teaching about seeing beyond maya (illusion) to underlying reality. The farmer saw the illusion—more sacks—but missed the reality—less purchasing power. Similarly, we see nominal money amounts while missing their real purchasing power. Krishna teaches Arjuna to look past surface appearances to understand true nature, which in economic terms means looking past nominal values to real values.
How Money Illusion Misleads Us Daily
In salary negotiations and job choices, money illusion makes people focus on nominal salary numbers while ignoring cost of living. Someone offered ₹80,000 per month in Mumbai might actually be worse off than someone earning ₹60,000 per month in Pune, once housing costs, transportation, and other expenses are considered. But the bigger nominal number makes the Mumbai job seem better even when real purchasing power is lower.
Similarly, workers resist nominal pay cuts even when accepting them would save jobs or the company. A company might offer everyone a five percent nominal pay cut during a crisis. Workers reject this angrily, feeling cheated. But if the company instead offers no raise during a period of five percent inflation—a real pay cut of the same magnitude—workers accept it much more readily. The nominal number staying the same feels acceptable even though purchasing power falls just as much.
In retirement planning, money illusion causes serious problems. Retirees often plan to withdraw a fixed nominal amount from savings each year—say ₹50,000 per month. But if inflation runs at six percent annually, after ten years that ₹50,000 buys what ₹28,000 bought when they retired. Their purchasing power has nearly halved while they think they’re withdrawing “the same amount” because the nominal number hasn’t changed.
Research from Harvard Business School shows that retirees who adjust withdrawals for inflation maintain stable living standards, while those who withdraw fixed nominal amounts experience declining living standards they don’t fully understand because their bank statements show “plenty of money” in nominal terms even as purchasing power evaporates.
In pricing and consumer behavior, businesses exploit money illusion. During inflation, companies raise prices in nominal terms but consumers resist, feeling they’re being charged “more” even when real prices may be stable or falling. Companies respond by shrinking package sizes instead—keeping the nominal price the same (avoiding money illusion resistance) while reducing product quantity (raising real prices silently).
The chocolate bar that cost ₹10 ten years ago and still costs ₹10 today seems like amazing value stability—until you notice it’s now thirty grams instead of the original fifty grams. The nominal price stayed the same, exploiting money illusion, while the real price per gram increased by sixty-seven percent. Consumers feel good about the stable nominal price while missing the higher real price.
In debt and borrowing, money illusion works in complex ways. Borrowers feel that high nominal interest rates are bad and low nominal rates are good, without properly considering inflation. A ten percent nominal interest rate during eight percent inflation means two percent real interest—borrowing is cheap. A four percent nominal rate during zero inflation means four percent real interest—borrowing is expensive. But borrowers focus on the nominal numbers (ten percent feels scary, four percent feels cheap) and make poor decisions as a result.
Governments sometimes exploit this, accepting high inflation partly because it reduces real debt burdens while nominal debt stays the same. If government owes ₹100 crore and inflation runs at ten percent, in real terms that debt shrinks by ten percent even though nominally it’s still ₹100 crore. Citizens see the nominal number unchanged and don’t realize debt burden has fallen through inflation eroding its real value.
Seeing Money Clearly
The most important principle for overcoming money illusion is always asking: “What can this money actually buy?” Don’t focus on whether you’re earning more rupees or fewer rupees—focus on whether those rupees buy more goods and services or fewer. This requires knowing the inflation rate and adjusting all nominal money amounts to real purchasing power amounts.
When evaluating salary offers, job changes, or raises, calculate real purchasing power, not nominal amounts. A ten percent raise during twelve percent inflation is a real pay cut. A zero percent raise during negative two percent inflation (deflation) is a real pay increase. A ₹100,000 salary in an expensive city might provide less real purchasing power than ₹70,000 in a cheaper city. Always account for both inflation and location-specific costs.
For long-term financial planning, think in real (inflation-adjusted) terms. If you’re planning retirement expenses, don’t think “I’ll need ₹50,000 per month.” Think “I’ll need today’s equivalent of ₹50,000 per month in purchasing power, which means the nominal amount will grow each year with inflation.” Build automatic inflation adjustments into all long-term financial plans and withdrawal strategies.
Understand that moderate inflation is normal and expected. Prices will generally rise over time, meaning the same nominal amount buys less as years pass. This is normal economic functioning, not a crisis. Planning for it means adjusting all long-term nominal amounts upward to maintain stable real purchasing power. Retirement nest eggs, insurance coverage amounts, and salary expectations should all rise with inflation to maintain constant real value.
Use inflation-adjusted (real) numbers when comparing financial situations across time. Don’t compare your current salary to your parents’ starting salary thirty years ago using nominal numbers—adjust for inflation. Your father’s ₹5,000 monthly salary in 1990 had roughly the purchasing power of ₹35,000 today. Without inflation adjustment, comparing nominal salaries across time periods is meaningless and misleading.
Remember Kavya’s father celebrating his raise without realizing inflation had given him a real pay cut, and the farmer celebrating his bigger harvest without noticing its smaller real value. Both focused on nominal amounts—more rupees, more sacks—while missing what those amounts could actually purchase. Money illusion makes us think in numbers on paper rather than in goods and services those numbers command. Breaking the illusion requires constant vigilance: always translate nominal amounts to real purchasing power, always account for inflation, and always remember that money is just a measuring tool, not wealth itself. Wealth is what money can buy, and that changes even when the money numbers don’t.
Frequently Asked Questions
How can I quickly adjust nominal amounts for inflation?
Find the inflation rate (available from government statistics or financial news), then apply it to nominal amounts. If something cost ₹100 last year and inflation was 6%, it should cost about ₹106 this year to maintain the same real price. Online inflation calculators can convert historical amounts to current purchasing power—your grandparents’ ₹50 monthly salary in 1950 had purchasing power of several lakhs in today’s rupees. Always mentally adjust when comparing money across different time periods.
Why do governments allow inflation if it confuses everyone?
Moderate inflation serves economic functions: it encourages spending rather than hoarding cash, makes debt easier to repay in real terms, allows real wage adjustments without nominal cuts (which workers resist due to money illusion), and provides monetary policy flexibility. However, governments do aim to keep inflation stable and moderate (2-6% annually) rather than too high (which causes serious economic harm) or negative (deflation, which creates different problems). The confusion from money illusion is a side effect, not a goal.
Is it better to focus on nominal or real values?
Real values for almost all long-term planning and comparison across time periods. Nominal values are fine for immediate transactions—when buying groceries today, the nominal price is what matters. But for salary comparisons, retirement planning, investment returns, long-term contracts, or comparing prices across years, you must use real (inflation-adjusted) values. Mixing nominal and real values, or comparing nominal values across time, creates illusions that lead to poor decisions.
Does money illusion explain why older people say “things were cheaper in our day”?
Partially. They’re correct in nominal terms—a movie ticket that costs ₹300 today might have cost ₹5 in 1970. But in real purchasing power terms, the comparison is complex. That ₹5 ticket in 1970 represented a larger portion of daily wages than ₹300 does today. Adjusted for wage growth and inflation, movies aren’t necessarily more expensive—they just have larger nominal prices. The money illusion makes the bigger nominal number seem like evidence things are more expensive when the real comparison is more nuanced.
Can money illusion ever be beneficial?
Sometimes yes. Money illusion makes it easier for employers to reduce real wages through inflation rather than nominal cuts, which helps companies adjust to economic conditions without mass layoffs that nominal cuts might require. It makes debts easier to bear over time as inflation erodes real debt burden while nominal amounts stay constant. However, these “benefits” come at the cost of confusion and poor financial planning. Most economists consider money illusion a harmful cognitive bias that leads to suboptimal decisions despite occasional coincidental benefits.
