Real Versus Nominal Wages

A nominal wage is just a number in dollars, the figure printed on a paycheck. It says nothing about what that money can buy. If prices are rising, the same number of dollars buys fewer goods than it used to, so the worker can be worse off even while their paycheck grows. The real wage fixes this by stripping inflation out, converting a dollar figure into base-year purchasing power so you can compare across time on equal footing.

The mechanism is division by a price index. Real wage equals nominal wage divided by the CPI, then multiplied by 100 to put the answer back into base-year dollars. The CPI tracks how much a fixed basket of goods costs relative to the base year, so dividing by it removes the effect of rising prices and leaves only the quantity of real purchasing power. A nominal raise is automatically a real raise only when it grows faster than the price level; otherwise the worker is treading water or losing ground.

This same split reappears with interest rates. The nominal interest rate is the rate stated by a bank, in dollar terms. The real interest rate subtracts inflation from it, showing the actual growth in purchasing power a saver or lender gets. Real wages and real interest rates are the same idea applied to two different prices: the price of labor and the price of money.
