Inflation Impact Analysis
Inflation erodes purchasing power over time. At 3% annual inflation, $100,000 today will cost $134,392 in 10 years - you'll need that much to buy what $100,000 buys today. Conversely, $100,000 in 10 years has only $74,409 purchasing power in today's dollars. Understanding inflation is crucial for retirement planning and long-term financial goals.
Historical US inflation averages 3% annually but varies - 1970s saw 7%+, recent years 2-4%, 2021-2022 spiked to 8%+. High inflation requires higher investment returns to maintain purchasing power. If inflation is 4% and investments earn 4%, you're not gaining real wealth - just keeping pace with rising prices.
Combat inflation by investing in assets that historically outpace it - stocks average 10% returns vs 3% inflation, real estate appreciates with inflation, TIPS bonds adjust for inflation. Cash in savings loses value in real terms if interest doesn't exceed inflation. Always calculate real returns (nominal return minus inflation) for accurate financial planning.
Quick Tips
- Always compare APR, not just interest rates
- Use the Rule of 72 to estimate doubling time
- Extra payments dramatically reduce total interest
