Real return (also called the real rate of return or inflation-adjusted return) is the return on an investment after taking inflation out, so it measures how much more you can actually buy, not just how many more units of money you hold. The return you normally see quoted, before inflation, is called the nominal return. The exact formula is (1 + nominal return) ÷ (1 + inflation rate) minus 1. A common shortcut is simply nominal return minus inflation, which is close enough when both numbers are small. A real return of zero means your purchasing power stood still, and a negative one means prices rose faster than your money grew.
Worked example
Say Fund A earns a nominal return of 8% in a year, and prices rise 3% over the same year. $10,000 grows to $10,800. A basket of goods that cost $10,000 at the start now costs $10,300. Real return = $10,800 ÷ $10,300 minus 1 = 1.0485 minus 1, which is about 4.85%. The shortcut gives 8% minus 3% = 5%, close but slightly high. Note the difference between the two numbers: your money grew 8%, but your buying power grew only about 4.85%.
Why it matters
Inflation quietly eats part of every return, and over many years the gap adds up. A savings account paying 2% while prices rise 3% has a negative real return: the balance grows, but it buys less each year. Real return is the figure to use when you plan long-term goals such as retirement, because the future bills are paid in future prices. Two cautions: inflation is a rate you only know afterwards, so any forward-looking real return rests on an assumption, and your own spending may rise faster or slower than the official price index. Taxes and fund fees also come out of the return and are not included in this simple formula.
Frequently asked questions
Divide one plus the nominal return by one plus the inflation rate, then subtract one. For example, 8% nominal and 3% inflation gives 1.08 ÷ 1.03 minus 1, about 4.85%. The shortcut of nominal minus inflation gives 5%, which is close when the numbers are small.
The nominal return is the gain in money terms, before inflation. The real return is the gain in buying power, after inflation. With high inflation the two can be far apart.
Yes. If prices rise faster than your investment grows, the real return is below zero: you hold more money than before, but it buys less.
