What Is the After-Tax Real Rate of Return?

The after-tax real rate of return is the actual financial benefit of an investment after accounting for the effects of inflation and taxes.

It is a more accurate measure of an investor’s net earnings after income taxes have been paid and the rate of inflation has been adjusted. Both of these factors must be accounted for because they impact the gains that an investor receives. This can be contrasted with the 澳洲幸运5官方开奖结果体彩网:gross rate of return and the 澳洲幸运5官方开奖结果体彩网:nominal rate of return of an investment.

Understanding the After-Tax Real Rate of Return

Over the course of a year, an investor might earn a nominal 澳洲幸运5官方开奖结果体彩网:real rate of return of 12% on his stock investment, but the real rate of return—the money he gets to put in hisไ pocket at the end of the day—will be less than 12%. Inflation might have been 3% for the year, knocking his real rate of return down to 9%. And since he sold his stock at a profit, he will have to pay taxes on those profits, taking more off his return, say 2%, for an after-tax real rate of return of 7%.

The 澳洲幸运5官方开奖结果体彩网:commission he paid to buy and sell the stock also diminishes his return. Thus, to truly grow their nest eggs over time, 澳洲幸运5官方开奖结果体彩网:investors must focus on the af🍸ter-tax real rate of return, n🐻ot the nominal rate of return.

The after-tax real rate of return is a more accurate measure of investment earnings and usually differs significantly from an investment’s nominal (gross) rate of return, or its return before fees, inflation, and taxes. However, investments in 澳洲幸运5官方开奖结果体彩网:tax-advantaged securities, such as municipal bonds and inflation-protected securities, such as 澳洲幸运5官方开奖结果体彩网:Treasury inflatio🐷n-prote💙cted securities (TIPS), as well as investments held in tax-advantaged accounts, such as 澳๊洲幸运5官方开奖结果体彩网:Roth individual retirement accounts (Roth IRAs), will show less discrepancy between nominal rates of return and after-tax real 𝔍rates of return.

Example of the After-Tax Real Rate of Return

Let’s be more specific about how the after-tax real rate of return is determined. First, the return is calculated by determining the after-tax return before inflation, which is calculated as nominal return × (1 - tax rate). For example, consider an investor whose nominal return on his equity investment is 17% and his applicable tax rate is 15%. Therefore, his after-tax return is: $0.17 \times (1 - 0.15) = 0.1445 = 14.45\%$0.17×(1−0.15)=0.1445=14.45%

Let’s assume that the inflation rate during this period is 2.5%. To calculate the real rate of return after tax, divide 1 plus the after-tax return by 1 plus the inflation rate, then subtract 1. Dividing by inflation reflects the fact that a dollar in hand today is worth more than a dollar in hand tomorrow. In other words, f❀uture dollars have less purchasing power than today’s dollar꧙s.

Following💜 our example,𒁃 the after-tax real rate of return is:

$\frac{(1 + 0.1445)}{(1 + 0.025)} - 1 = 1.1166 - 1 = 0.1166 = 11.66\%$(1+0.025)(1+0.1445)​−1=1.1166−1=0.1166=11.66%

That figure is quite a bit lower than the 17% gross return received on the investment. As long as the real rate of return after taxes is positive, however, an investor will be ahead of inflation. If it’s negative, the return will not be sufficient to sustain an investor’s standard of living in the future.

The Bottom Line

When you are assessing the value of your investments, it’s important to look at not just your nominal rate of return but also the after-tax real rate of return, which takes into account the taxes you’ll owe and inflation’s effect. The after-tax real rate of return can tell you if your nest egg investments will allow you to m𝄹aintain your standard of l♍iving in the future.
