Frequently asked questions
What is CPI?
The Consumer Price Index tracks a basket of consumer goods and services, published monthly by the BLS. It's the standard US measure of inflation.
Is 3% a good inflation assumption?
US CPI has averaged 3.1% over the last 100 years. Recent post-2020 has been much higher; the long-term Fed target is 2%.
Does inflation apply equally to everything?
No. Housing, healthcare, and education have inflated much faster than electronics and apparel. Personal inflation rate depends on your spending mix.
