1. Future cost: $100 x 1.03^10 = $134.39
2. Purchasing power: $100 / 1.03^10 = $74.41
3. Lost: $25.59 (25.6% decrease)

Result: $100 today will cost $134.39 in 10 years. $100 buys 25.6% less.

Tips & Best Practices

Average US inflation has been about 3% per year historically.
The Federal Reserve targets 2% annual inflation.
To maintain purchasing power, investments must return more than inflation.
Healthcare and education costs typically rise faster than general inflation.

Common Mistakes to Avoid

❌ Ignoring inflation in retirement planning.

✅ If you need $50K/year now, you will need about $67K/year in 10 years at 3% inflation. Factor this into savings targets.

❌ Assuming inflation is always the same.

✅ Inflation varies year to year. It was under 2% for most of 2010-2020, then spiked to 9% in 2022. Use a conservative long-term average.

Frequently Asked Questions

What is a normal inflation rate?

The US Federal Reserve targets 2% annual inflation. Historical average is about 3%. During 2021-2023, inflation reached 7-9% before declining.

How does inflation affect savings?

If your savings account earns 1% and inflation is 3%, you are losing 2% of purchasing power annually. Your money grows nominally but buys less. High-yield savings and investments help combat this.
