2. 背景與概念解釋
通貨膨脹（Inflation） 係指物價水平持續上升、貨幣購買力相對下降嘅經濟現象。主要概念包括：
- 購買力（Purchasing Power）： 一筆錢可以買到嘅貨物或服務數量。通脹越高，購買力越低。
- 累積通脹率（Cumulative Inflation）： 一段時間內嘅總通脹百分比。
- 名義金額 vs 實際金額： 名義金額係未來嘅面值，實際金額係調整通脹後嘅購買力。
- 通脹對儲蓄嘅影響： 如果銀行利率低過通脹率，你嘅儲蓄實際購買力會縮水。
3. 實際應用場景
- 退休規劃： 計算未來退休所需嘅實際金額，確保購買力足夠。
- 投資決策： 評估投資回報率是否跑贏通脹，確保資產保值。
- 長期儲蓄目標： 計算教育基金、買樓首期等目標嘅未來實際價值。
- 財務預算： 預測未來生活開支嘅增長幅度。
- 抗通脹策略： 比較不同投資工具（股票、債券、房地產）對沖通脹嘅效果。
4. 使用步驟

- 💰 初始金額（Starting Amount）
- 📈 平均年通脹率 %（Average Inflation Rate）
- 📅 時間跨度（年）（Time Span - Years）

Inflation Calculator Guide: Calculate Purchasing Power & Currency Depreciation — Inflation-Proof Your Finances
1. Introduction
Ever wondered what $100 today will be worth 10 years from now? Or whether your $1 million in savings will still have enough purchasing power for retirement? Inflation is a phenomenon that silently steals your wealth—prices rise, purchasing power falls, and your money becomes "worth less." Our free inflation calculator helps you calculate how inflation erodes purchasing power—enter amount, average inflation rate, and time span to instantly see future purchasing power and currency depreciation. All processing happens in your browser—your data never leaves your device, ensuring 100% privacy.
2. Background & Technical Concept
Inflation refers to the sustained increase in the general price level of goods and services, reducing the purchasing power of money. Key concepts include:
- Purchasing Power: The quantity of goods and services a sum of money can buy. Higher inflation = lower purchasing power.
- Cumulative Inflation: The total inflation percentage over a period of time.
- Nominal vs. Real Value: Nominal is the future face value; real value is purchasing power adjusted for inflation.
- Impact on Savings: If bank interest rates are lower than inflation, your savings' real purchasing power shrinks.
3. Real-World Application Scenarios
- Retirement Planning: Calculate the real amount needed for retirement to ensure sufficient purchasing power.
- Investment Decisions: Evaluate whether investment returns beat inflation to preserve asset value.
- Long-Term Savings Goals: Calculate the future real value of education funds, home down payments, and other goals.
- Budgeting: Forecast the growth rate of future living expenses.
- Inflation Hedging Strategies: Compare different investment vehicles (stocks, bonds, real estate) for hedging against inflation.

6. Personal Insights & Expert Advice
"My dad always says that when he was young, $10 could buy three full meals. Now, $10 can't even buy a cup of bubble tea. That's the power of inflation—your money doesn't decrease, but what you can buy with it does. Ignore inflation, and it will silently steal your purchasing power. At 3% inflation, your $1 million will only be worth $550,000 in today's money after 20 years—you didn't spend it, but nearly half disappeared. This tool gives you exactly that ability to see in 10 seconds how inflation erodes your wealth—so you start thinking about how to beat inflation, instead of leaving money in the bank to 'mold.'"
