Inflation and CPI Practice
Reprice a fixed basket of goods and watch the price index — and the inflation rate — move. Then answer five exam-style questions on the CPI, who wins and loses, substitution bias, and real wages.
One tile of the full inflation unit.
The course teaches inflation interactively — drag the graphs, practice with feedback, and spaced reviews bring it back before you forget. Free.

Five practice questions
Pick an answer, then click Check answer to see the explanation.
Question 1 of 5
What does the Consumer Price Index (CPI) measure?
Question 2 of 5
The CPI was 100 in the base year and is 130 this year. What is the inflation rate since the base year?
Question 3 of 5
A loan is agreed at a fixed interest rate, and then inflation turns out much higher than anyone expected. Who tends to gain?
Question 4 of 5
Why might the CPI overstate the true rise in a household's cost of living?
Question 5 of 5
Your nominal wage rises 3 percent this year, but the price level rises 5 percent. What happened to your real wage?
What the course adds
Beyond this one page
The inflation unit covers the CPI versus the GDP deflator, the costs of inflation, the difference between expected and unexpected inflation, and real-versus-nominal adjustments — with practice that targets the conversions you keep missing.
Spaced reviews
FSRS brings every concept back right before you'd forget. ~50% better retention than re-reading.
Per-concept mastery
Performance Factor Analysis tracks each sub-skill separately — you see which version of the idea is still wobbly.
Diagnostic placement
A short test skips you past what you already know. No re-learning the basics.
