Top Inflation Hedging Strategies & Assets
Holding uninvested cash against a $10,000 portfolio over 15 years guarantees erosion. Here is how institutional capital hedges purchasing power:
Treasury Inflation-Protected Securities (TIPS)
Principal value increases directly with the headline Consumer Price Index (CPI-U).
Series I Savings Bonds
Interest rate adjusts every 6 months directly benchmarked to non-seasonally adjusted CPI.
Broad Market Equities (S&P 500 Index)
Companies with pricing power increase revenue and dividend distributions as raw prices rise.
High-Yield Cash / Ultra-Short Treasuries
Short duration allows rapid re-investment at higher prevailing central bank interest rates.
Holding paper cash in checking accounts yielding 0.01% guarantees an immediate real-wealth loss equal to the annual inflation rate (~2.5%–4.0%). Diversifying across cash reserves, inflation-linked treasuries, and dividend equities preserves real purchasing power.

About Inflation & Purchasing Power Calculator
Inflation is often called the silent wealth tax because it continually diminishes the purchasing power of idle cash. ConvertSheet's Inflation Calculator illustrates the compounding effect of annual price increases over 1 to 50 years. Compare today's purchasing power with historical US CPI benchmarks (such as the 2% Fed target or historical 3.2% average) and export the year-by-year erosion schedule to Excel (.xlsx).

Frequently Asked Questions: Inflation & Purchasing Power Calculator
Answers to common questions regarding inputs, calculations, and mathematical methodology.
What is the Rule of 72 for inflation?
Divide 72 by the annual inflation rate to find approximately how many years it will take for prices to double (or for purchasing power to be cut in half). At 3% inflation, prices double in ~24 years.
How can individuals protect against inflation?
Assets historically shown to outpace inflation include broad-market equity index funds (S&P 500), Treasury Inflation-Protected Securities (TIPS), real estate with rental yield escalations, and hard commodities.
What is the difference between CPI and Core CPI?
CPI (Consumer Price Index) measures the broad price change of a basket of consumer goods and services. Core CPI excludes volatile food and energy sectors to provide a more stable reading of underlying macroeconomic inflation trends.
