How to Calculate the Percentage Gain or Loss on an Investment

Posted on
The primary aim of investing out there’s to make revenue. Consumers purchase stock from brokers or instantly at a set purchase worth, and when the time is true, they advertise to make a purchase on their funding. That’s the first method of making helpful properties from the market. The shares may be held long-term or temporary time interval; all of it truly depends on the form of tax regime the investor is attempting to look at.

Funding helpful properties rely fully on the acquisition and sale worth; nothing else impacts the decide as loads as these two values. Let’s understand % helpful properties in a bit of additional aspect.

What’s % Purchase?

With the intention to understand proportion purchase, it is first very important to understand what purchase is. Purchase is printed as a rise throughout the price of an asset (like market securities) that you just private. Say, as an example, that you just ought 50 shares worth $100 firstly of the month. By the highest of the month, these shares had been valued at $150 when you provided them. Given that worth of the sale was bigger than the worth of purchase for an asset, it resulted in a purchase. Versus losses that happen when the sale worth is lower than the acquisition worth, helpful properties are what make merchants hold invested on the market.

Proportion purchase, or % purchase, is a value obtained from the acquisition and product sales prices of a stock by using a stipulated technique.

Determining Proportion Purchase or Loss

  1. Take the selling worth and subtract the preliminary purchase worth. The result is the purchase or loss.
  2. Take the purchase or loss from the funding and divide it by the distinctive amount or purchase worth of the funding.
  3. Lastly, multiply the top outcome by 100 to achieve on the proportion change throughout the funding.

If the share appears to be unfavourable on account of the market price is lower than the distinctive purchase worth—moreover generally known as the value basis—there’s a loss on the funding.1 If the share is constructive on account of the market price or selling worth is bigger than the distinctive purchase worth, there’s a purchase on the funding.

Formulation for Calculating Proportion Purchase or Loss

textual content material{Funding proportion purchase} = frac{textual content material{Worth provided} – textual content material{purchase worth}}{textual content material{purchase worth}} events 100

  1. The share purchase or loss calculation will produce the dollar amount equal of the purchase or loss throughout the numerator.
  2. The dollar amount of the purchase or loss is cut up by the distinctive purchase worth to create a decimal. The decimal displays how loads the purchase represents as compared with how loads was initially invested.
  3. Multiplying the decimal by 100 merely strikes the decimal place to supply the share purchase or loss as as compared with the distinctive funding amount.

To seek out out the share purchase or loss with out selling the funding, the calculation could possibly be very comparable. The current market worth may be substituted for the selling worth. The top outcome may be the unrealized purchase (or loss), meaning the purchase or loss may be unrealized as a result of the funding had not however been provided.

Why Calculating Proportion Purchase or Loss Is Important

Calculating the purchase or loss on an funding as a proportion is important on account of it displays how loads was earned as as compared with the amount wished to comprehend the purchase.2

As an example, if two merchants each earned $500 from investing within the equivalent stock, they every had the equivalent amount of purchase. On the onset, evidently every investments achieved the equivalent finish outcome. Nonetheless, if one investor spent $20,000 when the stock was initially purchased, and the second investor spent solely $10,000, the second investor carried out larger on account of a lot much less money was at risk.

Moreover, the second investor would possibly make investments the alternative $10,000 (assuming every had $20,000 to take a place) in a second stock and earn an additional purchase.

Examples of Calculating Proportion Purchase or Loss

The share purchase or loss calculation may be utilized for lots of sorts of investments. Underneath are two examples.


As an example, let’s say an investor bought 100 shares of Intel Corp. (INTC) at $30 per share, which means that it value $3,000 for the preliminary funding ($30 worth * 100 shares).

The 100 shares had been provided for $38 per share, which means that the sale proceeds may be $3,800 ($38 per share * 100). The dollar price of the purchase on the funding may be $800 ($3,800 – $3,000).

The share purchase calculation may be:

  • ($3,800 sale proceeds – $3,000 distinctive value) / $3,000 = 0.2667 x 100 = 26.67%.

Alternatively, the purchase is perhaps calculated using the per-share worth, as follows:

  • ($38 selling worth – $30 purchase worth) / $30 = 0.2666 x 100 = 26.67%.


If an investor wished to learn how the Dow Jones Industrial Widespread (DJIA) has carried out over a positive interval, the equivalent calculation would apply. The Dow is an index that tracks 30 shares of most likely essentially the most established corporations in america.

Let’s say, as an example, that the Dow opened at 24,000 and closed at 24,480 by the highest of the week.

The share purchase calculation may be:

  • (24,480 – 24,000) / 24,000 = 0.02 x 100 = 2%

Explicit Issues: Fees And Dividends

Investing does not include out costs, and this must be mirrored throughout the calculation of proportion purchase or loss. The examples above did not ponder seller fees and commissions or taxes.

To incorporate transaction costs, reduce the purchase (selling worth – purchase worth) by the costs of investing.


Using the Intel occasion above, let’s say that the investor was charged $75 in fees from the seller. The share purchase may be calculated as follows:

  • (($3,800 sale proceeds – $3,000 distinctive value) – $75) / $3,000 = 0.2416 x 100 = 24.16%

We’re in a position to see that the brokerage cost diminished the share value of return on the funding by larger than 2% or from 26.67% to 24.16%.


If the funding paid out any earnings or distributions, resembling a dividend, the amount must be added to the purchase amount. A dividend is a cash price paid to shareholders and is configured on a per-share basis.4

Using the Intel occasion, let’s say the company paid a dividend of $2 per share. Given that investor owned 100 shares, Intel would pay $200 break up up evenly into 4 quarterly funds.

The share purchase may be calculated as follows:

  • (($3,800 sale proceeds – $3,000 distinctive value) + $200) / $3,000 = 0.3333 x 100 = 33.33%.

Assuming there have been no brokerage fees and the stock was held for one yr, we’re in a position to see that the dividend elevated the share value of return for the funding by larger than 6% or from 26.67% to 33.33%.

If the stock wasn’t held for one yr and, instead, was held for two quarters, we would add $100 to the purchase amount (instead of $200) as a result of the quarterly dividend funds may be $50 each.

By incorporating the transaction costs, account fees, commissions, and dividend earnings, merchants can obtain a further right illustration of the share purchase or loss on an funding.
