Title: Understanding the Real Interest on Your Post-Tax Income
Investing is a common strategy to grow wealth, but even if the value of your investments increases, inflation can erode your purchasing power. To account for inflation's impact, many investors calculate the "real" rate of return, which factors in taxes.
Understanding Real Returns
The objective of a real return is to determine if your assets are retaining their ability to purchase the same goods and services over time, despite inflation. Even if the dollar value of your investments increases (known as their "nominal" value), high inflation may result in a negative real rate of return if your investments don't generate enough returns to offset rising costs.
Consider an example. If you start with $100,000 and earn a 5% after-tax nominal return over a year, the portfolio will grow to $105,000 after taxes. However, if inflation also rose by 5% during the same period, you'd need $105,000 to buy the same amount of goods and services as $100,000 would have purchased earlier. In this case, your real return would still be 0% as the increase in the value of your investments is offset by inflation.
Calculating Real Returns
To calculate the real return, two crucial pieces of information are required. First, determine your after-tax nominal return, which can be found by dividing the value of your investments at the end of the period by their value at the beginning of the period. Second, determine the inflation rate over the same duration using historical Consumer Price Index (CPI) data.
Then, add 1 to both figures and divide the return-based number by the inflation-based number to calculate the real return.
For instance, if your nominal return was 10% and inflation was 4%, you would calculate:
- (1.10) / (1.04) = 1.0577
- 1.0577 - 1 = 0.0577 or 5.77%
In this example, the real after-tax return was 5.77%, indicating you were outpacing inflation. Conversely, a negative real after-tax return means you're losing ground to inflation.
