The **rate of return calculator** allows you to find the **annual rate of return of a given investment** (see investment calculator), which is **the net gain or loss through a given period expressed as a** **percentage** of the initial investment cost.

Note that the present tool allows you to **find the annual rate of return** from an investment, with the option to provide **regular cash flows** during the investment period. If you would like to find the internal rate of return (IRR) of an investment with irregular cash flows, use our IRR calculator.

In the following, we explain *what the rate of return is*, *how to calculate the rate of return on investment*, and you can get familiar with the *rate of return formula*.

## What is rate of return?

As you probably know, the fundamental principle of investing money is to **receive more money in the future than you provided at the beginning**. In other words, **investors expect a positive rate of return** on their investment. In finance, we call it a **required rate of return** because the opportunity for more money in the future is required to convince investors to give up money today.

However, keep in mind that the rate of return may have different meanings depending on its context. For example, if it is positive, **it suggests profit** **from an investor's viewpoint**, but **from the investee's perspective, it represents a cost**. For debt, we call this cost the interest rate. For equity, we call it the cost of equity, consisting of dividends and capital gains. Therefore, **the rate of return can indicate either the cost of money or the price of money**.

## The rate of return definition

In finance, a **return is a profit on an investment** measured either in absolute terms or as a percentage of the amount invested. Since the size and the length of investments can differ drastically, it is useful to **measure it in a percentage** form and compute **for a standard length** when comparing. When the time **length is a year**, which is the typical case, it refers to the **annual rate of return** or **annualized return**. If the investment performance is measured as return per dollar invested, we call it the return on investment (ROI).

There are other measures that reflect return from different perspectives:

- Return on invested capital (ROIC);
- Return on sales (ROS);
- Return On Capital Employed; and
- Return on Equity (ROE) (see return on equity calculator).

## How to calculate rate of return on investment – the rate of return formula

We can compute the rate of return in its simple form with only a bit of effort. In this case, you don't need to consider the length of time, but the **cost of investment** or *initial value* and the **received final amount**.

**rate of return = (final amount received - initial value) / initial value**

If the rate takes a negative form, we have a negative return, representing a loss on the investment, assuming the amount invested is greater than zero.

When we would like to account for the time length and effect of reinvested return, in particular the compounding frequency, things become tricky.

The fact is, at least according to mathematicians, there is no straightforward formula that can give an exact solution to find the rate of return. A traditional technique for such a problem is to employ the iteration method, which is a series of approximations leading us to the right answer. In our case, the iteration is made with the following rate of return formula (**ROR**):

**FV = PV × (1 + ROR) ^{n} + Pmt × (1 + ROR)^{n-1}**

where:

**FV**– Final amount received;**PV**– Initial investment; and**Pmt**– Periodic cash flow.

Since this procedure would take considerable time and effort, we use one of the most common iterative techniques in the present calculator, called the **ROR** from the rate of return equation above.

## How to apply the rate of return calculator?

The best way to get familiar with this tool is to consider three real-life examples. To simplify things, all the following examples involve yearly compounding and annual cash flows (if applicable).

1. **Finding the rate of return with positive cash flows**

**Example 1**

Steve got 1,000 dollars as a gift ten years ago, and he gave it to his older brother, a professional investor. During these 10 years, Steve gave his brother 100 dollars at the end of each year, and now his brother has returned 5,000 dollars to him. What rate of return did Steve earn?

The precise answer is **12.379%**, which appears if you set the initial investment to **$1,000** with a final amount of **$5,000**, **10** years investment length, and **$100** periodic deposit.

2. **Estimating the rate of return with interim cash flows**

**Example 2**

You just acquired an annuity, a financial product usually provided by insurance companies, that will pay you 5,000 dollars annually for ten years, and you receive the first payment today. Your friend, Jack, offers you 40,000 dollars for the annuity. If you sell it to him, what rate of return will Jack earn on the investment?

How to find the rate of return in this case? Your friend's initial investment is **$40,000** dollars with a zero final amount received but **5,000** dollars in withdrawals for **10** years. Keep in mind that you need to write **-$5,000** as withdrawals to represent a negative cash flow.

After setting these variables, you will immediately know that Jack will gain a **4.277%** return annually with a total withdrawal of **$50,000**.

**Example 3**

You just became a beneficiary of a life insurance policy. The insurance company gives you a choice of 100,000 dollars today or a 10-year annuity of 12,000 dollars at the end of each year. What rate of return is the insurance company offering? How do you calculate the rate of return with our calculator?

In this case, when you set **$100,000** as an initial investment and **-$12,000** for the periodic withdrawals, you will see that rate of return is **3.46%** with a total withdrawal of **$120,000**.

Note that in the present calculator, we deal with the nominal rate of return. If you would like to compute and learn about the inflation-adjusted real rate of return, please check our real rate of return calculator.

You should consider the annual rate of return calculator as a model for financial approximation. All payment figures, balances, and interest figures are estimates based on the data you provided in the specifications that are, despite our best effort, not exhaustive.

For this reason, we created the calculator for instructional purposes only. Still, if you experience a relevant drawback or encounter any inaccuracy, we are always pleased to receive useful feedback and advice.

## FAQ

### How do I calculate the rate of return?

You can calculate the rate of return in three steps:

- Determine the
**initial value invested**. - Calculate the
**final value received**. - Apply the
**rate of return formula**:

`rate of return = (final value - initial value) / initial value`

### What is the rate of return if I received $2,500 after investing $1,000?

Your rate of return will be `250%`

. You can calculate it using this formula:

`Rate of return = (final value - initial value) / initial value`

`Rate of return = ($2,500 - $1,000) / $1,000 = 2.5 = 250%`

### Is a higher rate of return always better?

While a higher rate of return usually **indicates a more profitable investment**, it often **comes with higher risk**. Diversification is critical for managing risk.

### What are real and nominal rates of return?

**The nominal rate of return does not account for inflation**, while the real rate of return does. The real rate of return gives a more accurate depiction of the changes in purchasing power.

**rate of return**is

**16.203%**.
