通胀影响计算器 Inflation Calculator

估算在不同年通胀率下，某一笔金额的购买力随时间如何变化，并比较未来等价金额。
Estimate how the purchasing power of a given amount changes over time under different inflation rates, and see the equivalent future amounts needed to maintain today’s purchasing power.

1. 输入参数 · Inflation Parameters
作为对比基准的金额，例如一年的生活开销、学费预算或一笔储蓄。
The reference amount in today’s money, such as annual living expenses, tuition, or a saving goal.
从现在开始到未来的年数。通胀通常按年测算，因此工具采用“年”为单位。
Number of years from now into the future. Inflation is usually measured annually, so we use years as the time unit.
情景 1 · Scenario 1
情景 2 · Scenario 2
情景 3 · Scenario 3
通胀率为 正值 时，价格总体上升、货币购买力下降；为 负值 时可视为通缩。
When inflation is positive, prices generally rise and purchasing power falls; a negative rate can be interpreted as deflation.
可用不同情景模拟：如“目标通胀 2%”、“长期平均 4%”、“高通胀 8%”等。
Use different scenarios such as “target inflation 2%”, “long-term average 4%”, or “high inflation 8%” for comparison.
3. 通胀与购买力小结 · Inflation & Purchasing Power
  • 复利效应（“温水煮青蛙”） · Compounding Effect:
    即使看起来不高的年通胀率（如 2%–3%），在 10–20 年后也会显著侵蚀购买力。
    Even seemingly low annual inflation (like 2–3%) can significantly erode purchasing power over 10–20 years.
  • 购买力剩余比例 · Remaining Purchasing Power:
    工具中“购买力剩余 X%”表示：如果金额名义上不增长，若干年后它能买到的东西仅相当于今天的 X%。
    “Remaining purchasing power X%” means that if the nominal amount does not grow, it will only buy X% of what it does today after a certain number of years.
  • 未来等价金额 · Equivalent Future Amount:
    若你希望在未来保持与今天相同的消费能力，你的资产或收入需要至少跟上通胀，甚至略高于通胀。
    To maintain today’s standard of living in the future, your income or assets generally need to grow at least in line with inflation, or slightly above it.
  • 理财启示 · Personal Finance Insight:
    长期只“存现金”而不进行任何增值投资，等同于默默承担了通胀带来的“隐形损失”。
    Keeping all your wealth in cash without any growth is effectively accepting an “invisible loss” caused by inflation over time.
