Frequently asked questions

How is inflation calculated?

We use the annual CPI-U (Consumer Price Index for Urban Consumers) published by the US Bureau of Labor Statistics. The calculation is simply: amount × (CPI in target year / CPI in start year).

Why does the CPI matter to me?

It's the single most-referenced measure of everyday inflation — used for Social Security COLA adjustments, tax bracket updates, and most economic reporting.

Does CPI capture all inflation I experience?

No. CPI reflects an average basket of goods. Rent, healthcare, and college tuition have historically outpaced CPI, while electronics and clothing have deflated.

How much has $1 lost since 1970?

Roughly 87–90% of its purchasing power. A 1970 dollar has the buying power of about $0.12 in 2025 dollars.

How do I protect savings from inflation?

Invest in productive assets that historically outpace inflation: stocks (~7% real), real estate, and Treasury Inflation-Protected Securities (TIPS). Cash under the mattress loses to inflation every year.
