Frequently asked questions
What is inflation? ▼
Inflation is the gradual increase in the general price level of goods and services over time, which reduces the purchasing power of money. Measured by the Consumer Price Index (CPI), the US averages around 3% per year historically.
Why does inflation matter for savings? ▼
Cash savings in low-yield accounts lose real value every year to inflation. $10,000 today is worth roughly $7,400 in today's dollars after 10 years at 3% inflation — a 26% purchasing power loss.
What inflation rate should I use? ▼
The Federal Reserve targets 2%. The 20-year historical US average is approximately 2.5–3%. For conservative planning, use 3–4%. For healthcare or education costs, which inflate faster, use 5–7%.
Disclaimer: This calculator uses a constant inflation rate assumption. Actual inflation varies year to year and differs by geography and category of goods.
