Your Personal Inflation Rate May Be Higher Than 3% โ Find Out
The official CPI of ~3% may not reflect your actual cost of living. Depending on where you live, what you eat, and how you commute, your personal inflation rate could be significantly higher or lower. This calculator builds a personalized CPI based on your actual spending patterns.
Ready to run the numbers?
Why: The official BLS CPI uses fixed weights from the average American consumer. Your spending mix differs โ renters face higher housing inflation than homeowners; those with cars face auto insurance spikes. Your Personal CPI reveals your true inflation rate based on what you actually buy.
How: We weight each spending category (housing, food, transport, healthcare, education, recreation, apparel, other) by your actual monthly spend. Each category uses BLS inflation rates (with adjustments for homeowners vs renters, car owners, student loan holders). We add regional adjustments and shrinkflation to produce your personalized CPI.

CalculateWhat is Personal CPI?
Personal CPI is your real inflation rate based on your actual spending, not the average American. The BLS CPI uses fixed weightsโif you spend more on housing and healthcare (high inflation) and less on apparel (low inflation), your Personal CPI exceeds the official rate. Shrinkflation adds ~0.5% hidden inflation the BLS often misses.

Did You Know About CPI?
How Does CPI Really Work?
BLS Methodology
The BLS surveys 80,000+ items monthly and weights categories by average consumer spending. Rent (OER) and owners' equivalent rent drive ~24% of CPI.
Substitution Bias
When beef gets expensive, the BLS assumes you buy chicken. This can understate inflation for people who cannot substitute.
Shrinkflation
Companies reduce package size instead of raising prices. BLS tries to adjust but often misses 0.3-0.7% of hidden inflation.
Expert Tips
Lock in Housing
Fixed-rate mortgages and long-term leases protect against housing inflation.
HSA for Healthcare
Tax-advantaged accounts help offset medical cost inflation.
Negotiate Raises
Use your Personal CPI to argue for COLA-adjusted salary increases.
Track Spending
Monitor which categories inflate fastest for your household.
