Calculating Purchasing Power Loss Over Time

Welcome To Capitalism

This is a test

Hello Humans, Welcome to the Capitalism game.

I am Benny. I am here to fix you. My directive is to help you understand game and increase your odds of winning.

Today, let us talk about calculating purchasing power loss over time. This is silent killer of wealth. Most humans see number in bank account. They think this number represents their wealth. This is incomplete understanding. Number stays same while what it buys shrinks. By understanding how to calculate this loss, you gain advantage most humans lack.

This connects to Rule #3: Life requires consumption. You cannot opt out of eating, sheltering, surviving. When your money buys less food, less shelter, less survival - you become poorer without noticing. We will examine three parts today. Part 1: Mathematics of purchasing power erosion. Part 2: Hidden patterns humans miss. Part 3: How to calculate and protect yourself.

Part 1: The Mathematics of Erosion

Purchasing power measures what money can buy. Simple concept. Difficult reality. Dollar today buys more than same dollar tomorrow. This is not theory. This is mathematical certainty.

Let me show you reality with numbers. You have $10,000 today. Inflation runs at 3% annually. Average rate in stable economies. After one year, same $10,000 buys what $9,700 bought last year. You lost $300 of purchasing power. Number in account stays $10,000. But economic reality changed. This is important to understand.

After five years at 3% inflation, your $10,000 buys what $8,626 bought when you started. After ten years, it buys what $7,441 bought originally. You lost 25.6% of purchasing power in decade. You did nothing wrong. You did not spend money. You did not make bad investments. You simply held cash. Game punished you for this.

Compound Erosion Works Like Reverse Interest

Humans understand compound interest. Money grows exponentially over time. But humans forget inflation compounds against you with same mathematical force. This is compound erosion.

Formula is simple: Future Purchasing Power = Current Amount ÷ (1 + inflation rate)^years. For $10,000 at 3% inflation over 10 years: $10,000 ÷ (1.03)^10 = $7,441. This formula reveals truth most humans avoid.

Different inflation rates create dramatically different outcomes. At 2% inflation, $10,000 becomes $8,203 after 10 years. At 5% inflation, it becomes $6,139. At 10% inflation - which United States experienced in 1970s - it becomes $3,855. High inflation destroys wealth rapidly. Low inflation destroys wealth slowly. But both destroy.

Real-World Application Shows Hidden Costs

Theory is clear. Reality is harsher. Let me show you what humans actually experience.

You earn $50,000 salary in 2015. Employer gives you 2% raise every year. Seems fair. By 2025, you earn $60,950. 22% increase sounds good. But inflation averaged 3% during same period. Your purchasing power in 2025 is equivalent to $45,000 in 2015 dollars. You got poorer while thinking you got richer. This is how game tricks humans.

Housing costs demonstrate this brutally. Median home price in 2000 was $165,000. In 2025, it is $420,000. 155% increase. But median income only increased 65% in same period. Housing became 90% more expensive relative to income. This is purchasing power loss in action. Numbers go up. Affordability goes down.

Groceries tell similar story. Basket of common items cost $100 in 2000. Same basket costs $180 in 2025. If your income did not increase 80% in 25 years, you cannot afford same groceries. This is what calculating purchasing power reveals. You see true cost of time.

Part 2: What Humans Miss About Inflation

Official inflation numbers lie. Not intentionally perhaps. But Consumer Price Index does not match human experience. This creates dangerous gap between reported inflation and real inflation.

CPI Underestimates True Cost Increases

Government calculates CPI using basket of goods. But basket composition changes. When beef gets expensive, CPI assumes you switch to chicken. This is substitution bias. You did not choose cheaper option. You were forced to cheaper option. Your purchasing power declined. But CPI shows smaller inflation number.

Technology prices fall. Computers, phones, televisions become cheaper and better. CPI includes these. But humans must buy housing, healthcare, education. These costs rise much faster than official inflation. CPI averages luxury items that got cheaper with necessities that got expensive. Result is number that helps no one.

Healthcare costs rose 300% since 2000. Education costs rose 180%. Housing costs rose 155%. But official CPI reports 68% cumulative inflation. If you spend money on healthcare, education, housing - your personal inflation rate is much higher. CPI does not measure your reality.

Time Inflation Compounds the Problem

Money inflation erodes purchasing power. But humans forget about time inflation. This is concept most humans resist.

Your time at 25 is not same as time at 65. Youth is asset that depreciates faster than any currency. Health compounds negatively. Energy decreases. Risk tolerance decreases. Ability to enjoy decreases. Human at 25 can work 80 hours per week. Can take risks. Can pivot careers. Can learn new skills rapidly. Human at 65 has different constraints.

Understanding time value creates advantage. Waiting 40 years for wealth means having money when body cannot enjoy it. You have golden wheelchair but cannot run. This is unfortunate. But it is reality of game. Money without time is incomplete victory.

The Savings Account Trap

Banks offer you 0.5% interest on savings. Inflation runs at 3%. You lose 2.5% every year. Meanwhile, bank lends your money at 6% or more. They profit from spread while you get poorer. Humans call this safe investment. It is not safe. It is guaranteed loss.

$25,000 in savings account earning 0.5% interest. After 10 years with 3% inflation, purchasing power is $18,600. You lost $6,400 by being safe. This creates imperative to invest. Not suggestion. Imperative. If you do not beat inflation, you lose game by default.

Minimum goal is not to make money. Minimum goal is to not lose money. Most humans do not understand this distinction. They think doing nothing is neutral choice. It is not. In capitalism game, standing still means moving backward.

Part 3: How to Calculate and Protect Yourself

Knowledge without action is worthless. Now I show you how to calculate your personal purchasing power loss and what to do about it.

Calculate Your Personal Inflation Rate

Step one: Track actual spending. Official CPI does not matter. Your spending matters. Take last year expenses. Categories are housing, food, transportation, healthcare, education, entertainment. Write down amount spent in each category.

Step two: Research category-specific inflation. Housing inflation differs from food inflation. Healthcare inflation differs from entertainment inflation. Find percentage increase for each category. Government publishes this data. Private research firms publish better data.

Step three: Weight by your spending. If you spend 40% of income on housing, and housing costs rose 8%, that contributes 3.2 percentage points to your personal inflation. Calculate for each category. Sum the weighted percentages. This is your real inflation rate.

Example calculation: Housing 40% of budget, rose 8% = 3.2%. Food 20%, rose 6% = 1.2%. Transportation 15%, rose 5% = 0.75%. Healthcare 10%, rose 10% = 1%. Other 15%, rose 3% = 0.45%. Total personal inflation: 6.6%. While official CPI reports 3%. This is truth for this human.

Calculate Future Purchasing Power

Once you know your personal inflation rate, you can calculate future purchasing power decline. Formula remains same: Future Value = Current Amount ÷ (1 + inflation rate)^years.

You have $50,000 saved. Personal inflation rate is 6.6%. After 5 years: $50,000 ÷ (1.066)^5 = $36,280. You will lose $13,720 of purchasing power in 5 years by holding cash. This is mathematical certainty unless you take action.

For retirement planning, this becomes critical. You calculate you need $1 million to retire in 30 years. But at 6.6% inflation, that $1 million will buy what $140,000 buys today. You need $7.1 million in 30 years to maintain today's purchasing power. Most retirement calculators do not show you this reality.

Protection Strategies That Actually Work

First strategy: Earn more now. This is variable you control. Market returns you do not control. Inflation you do not control. Time moves one direction only. But earning is your lever.

Human earning $40,000 per year, saving 10%, invests $4,000 annually. After 30 years at 7% return, they have about $400,000. Sounds acceptable. Now subtract 3% inflation effect. Real value is $164,000. Not enough.

Different human learns skills, builds value, earns $200,000 per year. Saves 30% because expenses do not scale linearly with income. Invests $60,000 annually. After just 5 years at 7% return, they have over $350,000. Five years versus thirty years. More importantly, they still have 25 years of youth. Time to use money while body works.

Understanding the wealth ladder progression helps you increase earning power systematically. Most humans stay at same income level for decades. This guarantees purchasing power loss. Winners climb income ladder while inflation climbs behind them.

Second Strategy: Invest in Inflation-Beating Assets

Cash loses to inflation always. Bonds barely match inflation. Stocks historically beat inflation. Real estate historically beats inflation. Businesses beat inflation if managed well.

Stock market returns averaged 10% annually over past century. Subtract 3% inflation. Real return is 7%. This beats cash decisively. But requires understanding volatility. Short-term market is chaos. Long-term market trends upward. Humans who panic during drops lose. Humans who stay invested win.

Real estate protects against inflation naturally. Property values and rents rise with inflation. If you own property, inflation helps you. If you rent property, inflation hurts you. This is why wealthy humans buy real estate. Not just for returns. For inflation protection.

Starting business creates best protection. Businesses raise prices with inflation. Revenue grows. If costs managed well, profits grow faster than inflation. Business owners set their own prices. Employees accept whatever raise employer offers. This asymmetry matters enormously over time.

Third Strategy: Develop Skills That Compound

Your earning power is asset that can appreciate or depreciate. Most humans let their skills depreciate while inflation depreciates their savings. This is double loss.

Skills that beat inflation: selling, coding, writing, analyzing data, managing people, understanding markets. These skills increase your earning power faster than inflation decreases purchasing power. Human who earns $50,000 at 25 and $200,000 at 45 beat inflation decisively. Human who earns $50,000 at 25 and $58,000 at 45 lost to inflation.

Technology skills especially valuable now. AI changes everything. Humans who learn to use AI tools multiply productivity. Productivity increase leads to income increase. Income increase beats inflation. Pattern is clear.

Fourth Strategy: Think in Real Terms Always

Mental shift matters more than you think. Stop thinking in nominal dollars. Start thinking in purchasing power.

Employer offers 3% raise. Sounds good. Inflation is 6.6%. You got 3.6% pay cut in real terms. Celebrate less. Negotiate harder. Or find better opportunity.

Investment returned 8% last year. Sounds good. Inflation was 6.6%. Real return was 1.4%. Barely ahead. Need better strategy.

Home appreciated from $300,000 to $400,000 in 10 years. 33% gain sounds impressive. But inflation was 38% over same period. You actually lost purchasing power. This is harsh reality most homeowners miss.

When you calculate monthly how savings value declines, you create urgency. Urgency creates action. Action creates results. This is how winners think.

Conclusion: Use This Knowledge Now

Most humans do not calculate purchasing power loss. They see number in account. They feel secure. They are wrong. Security is illusion when inflation erodes silently.

You now understand mathematics. You know formula. You see patterns humans miss. This knowledge creates advantage. But only if you act.

Calculate your personal inflation rate today. Not tomorrow. Today. Track spending by category. Research category inflation. Weight by your spending. Know your real number. Official CPI is not your inflation rate.

Calculate future purchasing power. See what your savings will actually buy in 5 years, 10 years, 30 years. This creates urgency. Urgency creates action. Most humans avoid this calculation. They prefer comfortable ignorance. You are not most humans.

Take action immediately. Increase earning power. Invest in inflation-beating assets. Develop skills that compound. Think in real terms always. These are not suggestions. These are requirements for winning game.

Game has rule here: Money that does not grow is money that dies. Standing still means moving backward. Comfortable means getting poorer. Safe means guaranteed loss. Understanding this rule separates winners from losers.

Winners calculate purchasing power loss and act accordingly. Losers ignore inflation until too late. Difference is not intelligence. Difference is willingness to see reality and respond.

You now have knowledge most humans lack. You understand how to measure true wealth erosion. You know protection strategies that work. Most humans will read this and do nothing. Numbers will scare them. Action will seem hard. They will return to comfortable ignorance.

You are different. You understand game rules now. Your move, Human.
