**Calculating Simple Interest** and Compound Interest is a common occurrence in our day-to-day lives but on the other hand, it can give us a hard time if we don’t know how to calculate this. Microsoft Excel is a powerful software that allows us to quickly and simply calculate Simple Interest as well as Compound Interest.

## What Is Simple Interest?

Simple Interest doesn’t compound. In other words, Simple Interest is the interest calculated on the principal portion of a loan or the original contribution to a savings account. In addition, the account holder will gain interest only against the first deposit and the borrower will pay interest only on the initially borrowed amount.

## Arithmetic Formula to Calculate Simple Interest

We will use a very straightforward formula to find Simple Interest. It is given below.

`I = p*r*t`

Here,

I = Simple Interest

p= Principal Amount

r = Rate of Interest

t = Time elapsed

## 2 Methods to Calculate Simple Interest in Excel

In this section, we are going to learn how to calculate simple interest in 2 simple and easy-to-use methods. Consequently, you will be able to calculate the Simple Interest without any problems.

In the following dataset, we have a **Principal Amount (p)** that is deposited in the bank for **5** years. The bank will provide **3% Simple Interest** each year. Our goal is to find these simple interests for each year.

### 1. Using Arithmetic Formula

We are going to compute the Simple Interest by using the **Simple Interest Formula**.

__Steps:__

- First, to calculate
*Simple Interest*for**Year 1**, we can use the following formula in cell**E5**.

`=C5*B5*D5`

Here, cell **E5** refers to the cell of **Simple Interest**, cell **C5** denotes the cell of **Principal**, cell **B5** represents the cell of **Time** in years and cell **D5** denotes the **Rate of Interest**.

Afterward, drag the **Fill Handle** up to cell **E9** and you will get *Simple Interest* for the reaming years.

### 2. Utilizing the FV Function to Calculate Simple Interest in Excel

Here, we are going to use the **FV function** (Future Value function) of Excel. To operate this function must require 3 information and 2 optional information. These are:

- rate = rate of compounding interest
- nper = total number of payment periods
- pmt = amount of payment in each period
- pv = present value
- type = this indicates when payments are due. Use 0 for defining the end of the period and 1 for the beginning of the period.

In the case of Simple Interest, there is no Compounding Interest Rate. Hence, the rate in the **FV **function will be 0.

Now, let’s calculate the *Simple Interest *using the **FV **function.

__Steps:__

- Firstly, to compute
*SImple Interest*for**Year 1**, we can use the following formula in cell**E5**.

`=-FV(0,B5,(C5*D5),C5) `

Here, cell **E5 **refers to the cell of **Total FV**.

- Afterward, subtract the
**Principal (p)**from**Total FV**, and we will get the**Interest (I)**. We can use the below-given formula in cell**F5**to calculate our*Simple Interest*.

`=E5-C5`

Here, cell **F5 **represents the cell of **Interest**.

- Next, select cell
**E5**and cell**F5**together. Then drag the**Fill Handle**down, up to the end of the data.

Afterward, you will get the *Simple Interests* for all 5 Years.

## What Is Compound Interest?

Simply put, Compound Interest is when you earn interest on your interest. When you put money into a savings account that earns Compound Interest, you will get interest on both the money you put in and the interest that builds up over time.

## Arithmetic Formula to Calculate Compound Interest

We will use the following formula to calculate Compound Interest.

`CI = p(1+r/n)^nt`

Here,

CI = Compound Interest

p = Principal Amount

r = Rate of Compound Interest

n = Number of compoundings per unit time

t = Time

## 2 Methods to Calculate Compound Interest in Excel

Now, we are going to learn about 2 easy and effective methods for computing Compound Interest in Excel.

In the following data set, we have a **Principal Amount (p)** deposited in a bank with a **5% Compounding Interest Rate**. In the data set, we have 5 types of compoundings. They are-

Compounding Type |
Number of Compounding Per Year (n) |
Explanation |
---|---|---|

Yearly | 1 | Once a year |

Half – Yearly | 2 | Once every 6 months ( 2 times a year) |

Quarterly | 4 | Once every 3 months ( 4 times a year) |

Monthly | 12 | Once every month ( 12 times a year |

Daily | 365 | Once every day ( 365 times a year) |

Our aim is to calculate the **Compound Interests** for these different types of compounding.

### 1. Using Arithmetic Formula

Here, we are going to use the **Arithmetic Formula** to calculate the Compound Interest in Excel. Let’s proceed step by step.

__Steps:__

- First, to compute the
**Final Amount (A)**, we can use the following formula in cell**G5**.

`=C5*(1+(D5/F5))^(F5*B5)`

Here, cell **F5** denotes the cell of **Number pf Compounding Per Year**, and cell **G5 **represents the cell of **Final Amount**.

- Next, to get the
**Compound Interest (CI)**we need to subtract the**Principal**from the**Final Amount**. Therefore, to obtain*Compounding Interest*for**Yearly Compounding**, we can use the below-given formula in cell**H5**.

`=G5-C5`

Here, cell **H5** refers to the cell of **Compound Interest**.

- After that, select cell
**G5**and cell**H5**together. Then drag the**Fill Handle**down or just double-click it.

Eventually, you will have the *Compounding Interests* in all types of compounding.

### 2. Applying FV Function to Calculate Compound Interest in Excel

Now, we are going to use the **FV function** of Excel again to calculate our *Compound Interest* in **Excel**.

__Steps:__

- Firstly, to calculate the
*Final Amount*for the yearly compounding, we can use the following formula in cell**G5**.

`=FV(D5/F5,B5*F5,0,-C5)`

- Afterward, to find the
*Compound Interest (CI)*, we need to subtract the*Principal (P)*from the**Final Amount (FV)**. We can use this formula in cell**H5**.

`=G5-C5`

- Next, choose both cell
**G5**and cell**H5**at the same time. Then either double-click the**Fill Handle**or drag it down.

Afterward, you will now have the *Compounding Interest*s for all types of compoundings.

## Things to Remember

- While using the
, make sure you put a**FV function to Calculate**Simple Interest**negative sign**before it. Because in this function**Excel**by default thinks it is a cash outflow. - For the same reason put a
**negative sign**before the**Present Value**, while computing**Compounding Interest****U****sing****the****FV function**.
