What is Inflation vs Deflation?
Inflation is a sustained increase in prices across the economy, reducing the purchasing power of your money—each dollar buys less. Deflation is the opposite: prices fall, and your money buys more. Both inflation and deflation create economic challenges for savers, investors and businesses.
Inflation means rising prices reduce your money's purchasing power. Deflation means falling prices increase it. Both distort the economy and hurt investments in different ways.
Step-by-step worked examples
Inflation at 5% annually. A coffee costs $3 today. How much will it cost in one year?
Annual inflation rate = 5% New price = $3 × (1 + 0.05) = $3 × 1.05 = $3.15 Your $100 buys less goods a year later
Deflation at 3% annually. A car costs $30,000 today. What is the price in one year?
Annual deflation rate = 3% New price = $30,000 × (1 − 0.03) = $30,000 × 0.97 = $29,100 But wages also fall and spending drops
$10,000 in savings with 4% inflation for 3 years. Real purchasing power?
After 1 year: 10,000 / 1.04 = 9,615 (in purchasing power) After 2 years: 10,000 / 1.0816 = 9,245 After 3 years: 10,000 / 1.1249 = 8,889 in real terms
