Inflation Impact Calculator
Find your real purchasing power
Find out if your raise actually keeps up with inflation — and what your expenses will look like in 1, 3, and 5 years.
Find your real purchasing power
The April 2026 CPI report showed headline inflation at 3.8% year-over-year — the highest reading in over a year, driven primarily by energy prices. But the 3.8% figure is an average across a market basket of goods weighted by typical spending patterns. Your personal inflation rate may be meaningfully higher or lower depending on how you actually spend money.
The Consumer Price Index measures price changes across eight major categories: food, energy, shelter, medical care, transportation, apparel, recreation, and education. The relative weights matter enormously. Shelter (housing) accounts for roughly 34% of CPI. If you own your home outright, that component barely affects your experience. If you are a renter in a high-cost market, your effective shelter inflation may be running 5–10% — far above the weight CPI assigns it in your situation. Energy at +17.9% year-over-year is the biggest current driver of the elevated 2026 headline. Households that drive more than average feel this acutely.
If your salary increased 3% this year and inflation is 3.8%, your real wage — your actual purchasing power — fell by 0.8%. For a $75,000 annual salary, that is roughly $600 in lost purchasing power this year alone. You are nominally making more and effectively affording less. This erosion compounds over multiple years of negative real wages. A worker who takes a 0.8% real pay cut for three consecutive years loses roughly 2.4% of their purchasing power, which on a $75,000 base represents $1,800 per year in real spending capacity that has quietly disappeared.
The calculator also shows how your savings rate compares to inflation. At 3.8% inflation, a high-yield savings account paying 4.5% APY is generating a positive real return of 0.7% annually. Money market accounts paying below 3.8% are effectively losing purchasing power despite appearing to grow. Traditional savings accounts at 0.5% are losing nearly 3.3% in real purchasing power per year — a significant cost of holding cash that most people do not think of as a cost. The difference between nominal and real returns is one of the most underappreciated concepts in household finance.
One of the most useful outputs of this calculator is the expense projection. At 3.8% inflation, a household spending $4,200 per month today will need approximately $5,100 per month in five years to maintain the same standard of living — assuming inflation stays constant. At 4.5%, the same expenses require $5,250 per month. These projections are particularly important for retirement planning, where fixed income sources (Social Security, pensions) lose real value over time while expenses rise.
