  • How to calculate future value?

  • What is the difference between future value and present value?

  • How can you use future value when making wise financial decisions?

And last but not least, in the text below, you will find out how to use our incredible future value calculator to make your financial decisions faster and smarter.

The time value of money

When explaining the idea of future value, it is worth to start at the very beginning. First of all, you need to know that the underlying assumption of future value is the concept of the time value of money. Actually, this idea is one of the core principles of financial mathematics. However, we believe that understanding it is quite simple, even for a beginning in finance.

Let's start with a simple question. Do you prefer to get one hundred dollars today or one hundred dollars after a year from today? If your answer is one hundred today, it means that you intuitively feel the idea of the time value of money. This concept says that one hundred dollars today is worth more than one hundred dollars tomorrow, or, more generally: money that is available now is worth more than the same amount in the future.

Are you wondering why this is? Why is the same amount of money worth more today than in the future? The answer lies in the potential earning capacity of the money that you have now. Note that when you have one hundred dollars from our example, you can put it in your savings account (or make any other investment), and after a year, you will receive more than your initial payment. In fact, it will be one hundred dollars plus additional interest. Formally, economists say that the future value of money is equal to its present value increased by interest. The question that appears here is how to actually calculate this future value of one hundred dollars. Keep reading, and we will try to explain this in details.

Future value definition

By definition, future value is the value of a particular asset at a specified date in a future. In other words, future value measures the future amount of money that a given investment is worth after a specified period, assuming a certain rate of return (interest rate).

More formally, the future value is the present value multiplied by the accumulation function. This function is defined in terms of time and expresses the ratio of the future value and the initial investment.

Why you need to calculate future value?

It's important to know how to calculate future value if you're a business owner or, indeed, any owner of appreciable assets. Once you know how valuable your assets currently are, it's important to know how valuable they will be at any given point in the future. That way, you can plan more intelligently for what's to come. It's important to use a future value calculator in order to get around the problem of the fluctuating value of money.

Ultimately, money is our way of assigning a number to value. That's why understanding how to calculate the core value of assets, in the present and in the future, is so crucial.

Future value formula

In its simplest version, the future value formula includes the asset's (or the investment) present value, the interest rate, and the number of periods between now and the future date.

Taking into account these variables, you can present the future value equation in the following way:

FV=PV(1+r)n\mathrm{FV} = \mathrm{PV} \cdot(1+r)^n


  • FV\mathrm{FV} – future value
  • PV\mathrm{PV} – present value (the initial balance of your investment)
  • rr – interest rate (expressed on an annual basis)
  • nn – the number of periods (years) the money is invested for.

This formula is applied to investments in which the compounding period is the same as the period for which the interest rate is calculated (e.g., a yearly compounding and an annual growth rate). Sometimes, however, the interest is compounded on a more frequent basis (quarterly or monthly). In such cases, to obtain the future value of your investment, you need to use a more complex formula:

FV=PV(1+rk)nk\mathrm{FV} = \mathrm{PV} \cdot \left(1+\frac{r}{k}\right)^{n\cdot k}


  • kk — the compounding frequency (the number of times the interest is compounded per year).

If you don't know all the values in this equation, feel free to use our present value calculator to assess your investment's value at the present moment, and our compound annual growth rate (CAGR) calculator to be sure you plug in the correct interest rate. Usually, the period will be one year, as interest rates are often calculated annually.

How to calculate future value? – examples of calculations

Do you want to understand the future value equation? Are you curious how to calculate the future value on real-life examples? Do you need to know how to find the interest rate that will give you a certain profit within a specified period? Or maybe you want to know how much time it will take you to double your initial investment?

We have prepared a few examples to help you find answers to these questions. After studying them carefully, you shouldn't have any trouble with understanding the concept of future value. We also believe that thanks to our examples, you will be able to make smart financial decisions.

Example 1 – Calculating the future value

The first example is the simplest case in which we calculate the future value of an initial investment. Assume that today you make a single deposit of $1,000. The annual interest rate is 4% and it is compounded yearly. What is the future value of this investment after 3 years?

Based on the future value formula presented in the previous section, we can calculate:

FV=$1, ⁣000(1+0.04)3=$1, ⁣0001.1248=$1, ⁣124.8\begin{split} \mathrm{FV} &= \$1,\!000\cdot\left(1+0.04\right)^{3}\\ & = \$1,\!000\cdot1.1248\\ &=\$1,\!124.8 \end{split}

The value of your deposit after 3 years (the future value) is $1,124.8.

Let's check now what the future value of the initial amount ($1,000) will be if the annual interest rate is compounded monthly. The formula for future value is:

FV=$1, ⁣000(1+0.0412)312=$1, ⁣0001.1273=$1, ⁣127.3\begin{split} \mathrm{FV} &= \$1,\!000\cdot\left(1+\frac{0.04}{12}\right)^{3\cdot12}\\[1em] & = \$1,\!000\cdot1.1273\\[.5em] &=\$1,\!127.3 \end{split}

This time the future value of your deposit is $1,127.3. Have you noticed that this value is higher (by $2.44) than previously and the only thing that has changed is the compounding frequency? You can say then that the more frequent the compounding, the higher the future value of the investment.

Example 2 – Calculating the present value

In the next example, we will show you how to calculate the present value of any investment. Let's assume that you make a deposit today and want the deposit to grow to $8,000 at the end of 5 years. Knowing that the annual interest rate compounded annually is 3%, calculate the present value of the deposit. In other words, you can ask what amount you need to invest today in order to have $8,000 after 5 years?

The basic transformation of the future value formula allows you to compute the present value:

FV=PV(1+r)n\mathrm{FV}=\mathrm{PV}\cdot \left(1+r\right)^n


PV=FV(1+r)nPV=$8, ⁣000(1+0.03)5=$6, ⁣900.87\begin{split} \mathrm{PV}&=\frac{\mathrm{FV}}{\left(1+r\right)^n}\\[1.4em] \mathrm{PV}&=\frac{\$8,\!000}{\left(1+0.03\right)^5}\\[1.4em] &=\$6,\!900.87 \end{split}

In our example, if you want to have $8,000 after five years, the initial deposit should be equal to $6,900.87.

Let's consider now what will change if we assume a different compounding period, for example, a quarterly compounding (k=4k = 4).

The respective formula for present value is:

PV=FV(1+rk)nk\mathrm{PV} = \frac{\mathrm{FV}}{\left(1+\frac{r}{k}\right)^{n\cdot k}}


PV ⁣= ⁣$8, ⁣000(1+0.034)54=$6, ⁣889.52\mathrm{PV}\! =\! \frac{\$8,\!000}{\left(1+\frac{0.03}{4}\right)^{5\cdot4}}=\$6,\!889.52

This time the initial deposit should be equal to $6,889.52. Have you noticed that this amount is slightly lower than the previous one? It is the result of the more frequent compounding.

Example 3 – Calculating the number of time periods

In the third example, let's consider another type of question. Firstly, let's assume that you make a simple deposit of $1,000. Like the first example, the annual interest rate is 4%, and it is compounded annually. How many years will it take your deposit to have a future value of $1,200?

To obtain the result, first of all, we need to transform the future value equation in the following way:

FV=PV(1+r)n\mathrm{FV} = \mathrm{PV}\cdot (1 + r) ^ n

When both sides are divided by PV\mathrm{PV}:

FVPV=(1+r)n\frac{\mathrm{FV}}{\mathrm{PV}} = (1+r) ^ n


log1+r(FVPV)=n\log_{1+r}\left(\frac{\mathrm{FV}}{\mathrm{PV}}\right) = n

If the compounding period is not the same as the period for which the interest rate is calculated the formula is:

log1+rk(FVPV)k=n\frac{\log_{\frac{1+r}{k}}\left(\frac{\mathrm{FV}}{\mathrm{PV}}\right)}{ k} = n

Now, let's try to put values from the example into this formula:

n=log1.04(1, ⁣2001, ⁣000)=4.65n = \log_{1.04}\left(\frac{1,\!200}{1,\!000}\right) = 4.65

It means that it will take 5 annual periods for a $1,000 deposit to go from its present value to the future value of $1,200.

What will change if we assume a monthly compounding period? We suggest you try to work it out by yourself. Remember that you can always check your results with our future value calculator – it works in each direction, depending on the values you provide.

Example 4 – Calculating the interest rate

In this example, we present how to calculate the interest rate that is earned on a given investment. The initial balance of today's investment is $15,000. After four years, the payoff (future value) from this investment will be $17,000. Assuming that the interest is compounded on an annual basis, what is the yearly interest rate of this investment?

Similarly, as in the previous example, let's start with a transformation of the future value formula:

FV=PV(1+r)n\mathrm{FV} = \mathrm{PV}\cdot (1 + r) ^ n

Firstly, you need to divide both sides by PV\mathrm{PV}:

FVPV=(1+r)n\frac{\mathrm{FV}}{\mathrm{PV}} = (1 + r) ^ n

Then raise both sides to the power of 1/n1 / n:

(FVPV)1n=1+r\left(\frac{\mathrm{FV}}{\mathrm{PV}}\right) ^{\frac{1}{ n}} = 1 + r

The last step is to deduct 11 from both sides:

(FVPV)1n1=r\left(\frac{\mathrm{FV}}{\mathrm{PV}}\right) ^ {\frac{1}{ n}} – 1 = r

When the compounding period is not the same as the period for which the interest rate is calculated:

((FVPV)1n1)k=r\left(\left(\frac{\mathrm{FV}}{\mathrm{PV}}\right) ^ {\frac{1}{ n }} – 1\right) \cdot k = r

So the solution of our example is as follows:

r=(17, ⁣00015, ⁣000)141=3.18%r = \left(\frac{17,\!000 }{15,\!000}\right) ^ {\frac{1 }{ 4}} – 1 = 3.18\%

The yearly interest rate in the considered investment is then 3.18%.

Try to calculate the annual interest rate on this investment if interest is compounded monthly. Is this interest rate higher or lower than interest rate from the example? What is the reason for that? Once again, in case you are not sure about your results, feel free to use our calculator – it is able to compute the interest rate based on the other information that you provide.

How to double your money? – the rule of 72

The Rule of 72 tells you how much time it takes for something to double, given a certain level of constant growth rate. This rule is a simple technique that allows you to estimate quickly:

  • The time it takes your initial deposit to double when you know the interest rate; or
  • The interest rate you need to double your initial deposit within a specified period.

The Rule of 72 says that the deposit will double when:

rn=72r\cdot n = 72


  • rr — Interest rate per period (year); and
  • nn — Number of periods (years).

For example, the Rule of 72 states that your initial deposit earning 6% per year compounded annually will double in 12 years. We know it from the following equation:

6%n=726\% \cdot n = 72


n=726=12n = \frac{72}{ 6} = 12

From another point of view, the Rule of 72 indicates that, to double the investment in 6 years, it should earn 12% per year, compounded annually:

r6=72r\cdot 6 = 72


r=726=12r = \frac{72 }{ 6} = 12

You can find more details and interesting information about the Rule of 72 at our original rule of 72 calculator.

What's future value (FV)?

Future value is the calculated value of an asset or cash flow at a specific point in the future. It's a way to measure an investment's potential worth or to estimate future earnings from an asset.

For example, if you were to invest $1000 today at a 5% annual rate, you could use a future value calculation to determine that this investment would be worth $1628.89 in ten years.

What's the future value formula?

The future value formula can be expressed in its annual compounded version or for other frequencies.

The future value formula using compounded annual interest is:

FV = PV⋅(1 + r)n


  • FV — Future value;
  • PV — Present value;
  • r — Annual interest rate; and
  • n — Years the money is invested.

When the interest is compounded at other frequencies (quarterly or monthly), the formula to determine the future value results in:

FV = PV⋅(1 + r/k)n⋅k


  • k – Compounding frequency.

What's the future value of $1,000 after five years at 8% per year?

The future value is $1,469.33. Let's see how we obtained this:

  1. Use the future value (FV) formula:

    FV = PV⋅(1 + r)n

  2. Substitute the known values for present value (PV), annual interest rate (r) and number of years of the investment (n):

    FV = $1000⋅(1 + 0.08)5

  3. Perform the corresponding numerical calculations and obtain the future value:

    FV = $1,469.33

What's the difference between future value and present value?

The difference between future value (FV) and present value (PV) is that FV focuses on the potential value of an asset at a specific time in the future, whereas PV considers how much your future earnings are worth today.

For example, use PV to calculate how much you’d need to invest today to have $1,000 in five years. FV tells you how much money you'll have in five years by investing $1,000 today.
