Total return combines price change and income: it adds any rise or fall in value to dividends or interest received, and the result can be negative.
Rate of return puts the gain or loss in proportion: it compares the result with the amount you started with.
Net return is what is left after costs and taxes: it subtracts the fees and taxes not already reflected in the gross figure.
An unrealized gain is not cash in hand: it is based on today's market value, not on what you will definitely receive when you sell.
What is total return?
Total return is the result of an investment over a period of time. It includes both the change in the asset's value and any income the asset produced. The result can be positive or negative.
For a stock, the two usual parts are the rise or fall in price and any cash dividends. For a bond, they are the change in the bond's value and the interest it pays. If you look only at a price chart or only at an advertised interest rate, you miss part of the result.
A simple way to picture it: check two places. How much is the asset worth now, and how much money has it paid you along the way? Price change and income need to be looked at together, not judged one at a time.
How to calculate total return: a worked example
Work out the gain or loss in money
For an investment bought once, with no money added or withdrawn during the period, you can use a simple formula:
Gross total return = Ending value − Starting value + Income received during the period.
"Gross" here means before the investor's own costs and taxes are deducted. Income is money the asset generates, not money you put in yourself. The formula reflects the two sources of return: change in value and income.
Suppose Mai buys a block of shares worth VND 10,000,000. A year later, those shares have a market value of VND 10,600,000, and Mai has received VND 400,000 in cash dividends. She keeps the dividend cash separately, does not reinvest it, and does not change the number of shares she holds.
Component | How it is worked out | Amount |
|---|---|---|
Change in value | VND 10,600,000 − VND 10,000,000 | VND 600,000 |
Cash dividends | Income received during the year | VND 400,000 |
Gross total return | VND 600,000 + VND 400,000 | VND 1,000,000 |
If Mai looked only at the price rise, she would record VND 600,000 and miss the dividends. If she looked only at the dividends, she would miss the change in the shares' value. This is a hypothetical example to practice the calculation, not a forecast or a recommended return.
Work out the rate of return
The gain or loss in money tells you the result in VND. The rate of return tells you how big that result is compared with what you started with:
Gross total rate of return = Gross total return ÷ Starting value × 100%.
In the example, VND 1,000,000 ÷ VND 10,000,000 × 100% = 10% for the year in question. The same VND 1,000,000 gain on a starting investment of VND 20,000,000 would be a rate of return of only 5%, not 10%.
This formula does not work directly for an account where money was added or withdrawn several times during the period. In that case, the timing and size of each cash flow need separate treatment. A growing account balance does not necessarily mean the investments made money.
If you received dividends, is the investment making money?
Positive income does not guarantee a positive total return. Suppose that after a year the shares in the example were worth only VND 9,200,000, while the dividends were still VND 400,000. The gross result would be:
VND 9,200,000 − VND 10,000,000 + VND 400,000 = −VND 400,000, or −4%.
Mai received cash, but the fall in value was larger than the income. In the same way, bond interest does not automatically make up for every loss if you sell the bond for less than you paid.
Dividends are also not "free extra money" paid while the share price stays put. The price can adjust when the right to receive the dividend is separated from the share (the ex-dividend date). What you need to judge is still the whole result, not just the cash paid out.
How is gross return different from net return?
The gross return in the example is the result before costs and taxes. Net return is what remains after subtracting the relevant costs and taxes that are not already reflected in that result.
Suppose Mai's total costs and taxes come to VND 250,000, an amount assumed only for illustration. Her VND 1,000,000 gross return would then leave VND 750,000 in net return. Real amounts depend on the actual transactions, the product and the rules that apply. Do not treat this assumed figure as a fee schedule or tax guidance.
If the gross return were only VND 200,000 but the relevant costs and taxes were VND 250,000, the net result would be a loss of VND 50,000. An investment that is profitable before costs can still leave you with a loss after them.
Check your investment costs, such as trading fees or account maintenance fees. If a fee has already been deducted from the asset value or the income figure you are using, do not subtract it a second time. Tax is also not always as simple as one rate multiplied by your total return.
What should you check when you read a return figure?
Has it been sold, or is it still held?
If Mai has not sold her shares at the end of the year, the VND 600,000 change in value is an unrealized gain. It is calculated at the market price on the day it is measured; it is not sale proceeds she has collected. The cash dividends already paid are income received. Both can still sit inside the total return at that point.
When you sell, the actual trading price can differ from the reference price, and there are costs as well. So the figure you see on screen is not a promise of how much you will receive if you sell in the future.
Is it the same period and the same method?
A 10% return over one year is not the same as 10% over three years. Before comparing figures, check the start date, the end date, and whether the number shows the return for the whole period or an annualized (per-year) return.
You also need to know whether the figure includes income, whether that income was reinvested, and which costs have been deducted. If dividends were reinvested and the ending value already includes the extra shares bought with them, do not add those dividends again as if you were still holding them as cash.
What does the figure tell you, and what does it leave out?
Total return measures a result. It does not tell you how much risk was taken along the way, or whether the investment suits the date when you will need the money. Past results and calculation assumptions do not guarantee future results. Learning to measure return is about reading information correctly, not about choosing an investment just because it shows a high number.
Next step
Total return shows where an investment's result comes from: price change plus income, minus the costs and taxes that apply. That raises a wider question: how do people describe the movement of a whole group of securities rather than a single holding? The next lesson explains stock market indexes, what an index represents, and why an index rising does not automatically mean an individual investor earned that return.
