To effectively track your progress toward financial goals, staying vigilant is crucial. You can assess the outcomes of your investments in two primary ways: by calculating yield and return.
- Yield measures the income generated by your investments, expressed as a percentage of your initial investment. It gives you insight into how much cash flow your assets are producing.
- Return, on the other hand, reflects the overall change in value of your investments, taking into account both capital appreciation and any income generated. It provides a more comprehensive view of your investment performance over a specific period.
By monitoring both yield and return, you can gain a clearer understanding of how your investments are contributing to your financial objectives.
Yield and return formulas
Yield
Yield is what you collect in income on an investment, expressed as a percentage of the amount you spent for your investment. For example, the $50 annual interest payment you get on a bond you bought for $1,000 is a 5% yield.
$ 50 Interest or dividends ÷ $ 1,000 Amount you invested = 5% Yield
Return
Return, or more precisely total return, is the amount your investment increases or decreases in value, plus any income you receive. For example, if you earn $150 on a bond and can sell it for $1,010 instead of the $1,000 you paid for it, your total return is $160 ($150 interest + $10 increase in value = $160).
$ 1,010 Sale price – $ 1,000 Investment = $ 10 Increase in value
$ 10 Increase in value + $ 150 Income from investment = $ 160 Total return
Annual Percent Return
$ 160 Total return ÷ $ 1,000 Amount you invested = 16% Percent return

$ 16% Percent return ÷ $ 3 Number of years = 5.3% Annual percent return
Percent return
Understanding percent return is crucial for evaluating your investments and making informed decisions about your portfolio. By comparing the percent return of a large-company mutual fund to its benchmark or category average over several years, you can determine whether it’s time to reallocate your assets into a similar fund with a stronger performance record.
When holding individual investments and not reinvesting your dividends or interest, calculating percent return is straightforward. Here’s how it works:
- Calculate Total Return: Add your income (dividends or interest) to any increase or decrease in the investment’s value.
- Determine Percent Return: Divide this total return by the amount you initially invested.
- Find Average Annual Percent Return: To compute the average annual percent return, simply divide the percent return by the number of years you’ve held the investment.
This method allows you to assess the performance of your investments clearly and decide whether to maintain or adjust your portfolio accordingly.

When your earnings are reinvested, calculating percent return becomes a bit more complex because each reinvestment increases your cost basis, or total investment amount. Simply dividing your total return by the original investment would yield an inflated figure.
The good news is that retail mutual funds routinely calculate their percent return, factoring in reinvested earnings minus expenses over various periods. While the actual percent return on your account may differ slightly from the figures reported by the fund—primarily due to the timing of your share purchases—the results are sufficiently accurate to give you the insights you need for informed decision-making.
Current yield
Current yield on a fixed-income investment, such as a bond, is the amount you’re earning in relation to the current price rather than the amount you invested. It’s a useful number for valuing your investments in the current market.
When return is real?
When calculating the return on your investment, it’s essential to consider another critical factor: inflation, which refers to the gradual decrease in the value of money over time.
Inflation is a persistent force that steadily erodes your purchasing power. As a result, you need to generate more income each year just to maintain the same standard of living you currently enjoy. This concern becomes increasingly significant the further into the future you project your income needs.
Real return is the actual return an investment yields after accounting for the current inflation rate. For instance, if a stock fund in your portfolio reports a one-year return of 8% and inflation is 3% during that same period, the real return on your investment is 5% (8% return – 3% inflation = 5% real return). In other words, the real return reflects the portion of your return that truly matters, as it indicates the rate at which you’re keeping pace with or outpacing inflation.

8% Total return – 3% Inflation rate = 5% Real return
The significance of real return highlights why it’s crucial not to overly focus on fixed-income investments in your retirement portfolio. Generally, fixed-income investments offer lower average returns compared to equities. Consequently, the impact of inflation on their real return is proportionately more pronounced. By maintaining a well-diversified portfolio that includes equities, you can better position yourself to outpace inflation and achieve a more favorable real return on your investments.
Realized vs unrealized gains
While the actual return on an investment isn’t finalized until you sell it and assess your overall standing, you can keep track of reinvested earnings and fluctuations in value by monitoring your current account balance. Just be careful not to confuse the contributions you add to your account with the returns generated by your investment. If your increase in value equals the contributions you’ve made, it indicates that your investment isn’t yielding a positive return.
Gains reflected on paper, as opposed to those realized in your pocket or bank account, are termed unrealized gains. Once you sell, any gains transform into realized gains. Realizing a gain means that the investment can no longer appreciate in value, but it also eliminates the risk of potential depreciation. Conversely, you can experience unrealized losses, particularly in the short term. If you sell an investment for less than what you initially paid, you realize a loss.
In conclusion
While there’s no one-size-fits-all answer for what constitutes an ideal investment return, it’s clear that the higher your return over the long term, the more your retirement savings can flourish. A common strategy is to aim for an overall annual return of 6%. Any years in which you exceed this benchmark can be seen as a pleasant bonus.
However, if you find that your average annual return hovers around 3% instead of the target 6% during your accumulation phase, it may raise red flags: such a shortfall could jeopardize your retirement fund’s ability to generate the income you need.
