## What Is Daily Simple Interest?

**Simple interest** is calculated on the principal amount of a loan or the initial deposit into a savings account. For daily simple interest, interest is accrued every day. The **daily Interest rate** is calculated by dividing the **annual interest rate **by **365**.

The** simple interest** is calculated by multiplying the **principal amount** by the **daily interest rate** by the number of days which is **1** for **daily simple interest**.

The formula for calculating simple interest is,

**Simple Interest = P*r*t**

Where,

**P = Principal Amount**

**r = Interest Rate (Daily)**

**t = Time (Days)**

For daily simple interest, the formula will be:

Here,** t = 1 day**

So, **Daily Simple Interest = P*r*1**

The formula for calculating the final amount is,

**Final Amount = P*(1+r*t)**

## 3 Easy Ways to Calculate Daily Simple Interest in Excel

For this tutorial, I have taken a dataset that contains the **Principal Amount**, **Interest Rate (Daily)**, and **Time (Days)**. I will be using this same table for calculating all the methods. I will explain 3 different methods on how to calculate **daily simple interest** in Excel.

### 1. Using Generic Formula to Calculate Daily Simple Interest in Excel

In this method, I will be using the generic formula for calculating **daily simple interest**.

For example, you have **$10,000** as your** Principal Amount**. Now, with a daily **Interest Rate** of **0.05%**, I will show you how you can calculate the **Final Amount** after **1 **day and the **Daily Interest**.

Let’s see step by step how to calculate **daily simple interest **in Excel by using the generic formula.

**Steps:**

- Firstly, select the cell in which you want to calculate the
**Final Amount**. Here, I selected cell**C9**. - Secondly, in cell
**C9**write the following formula,

`=C5*(1+C6*C7)`

Here, I **multiplied** the **Interest Rate (Daily)** by **Time (Days)**. And then, **summed** it with **1**. Finally, **multiplied** this whole value by the** Principal Amount** to get the **Final Amount**.

- Now, press
**ENTER**and you will get the**Final Amount**.

- After that, select the cell where you want to calculate the
**Daily Interest**. Here, I selected cell**C10**. - Next, in cell
**C10**write the following formula,

`=C9-C5`

Here, I** subtracted** the **Principal Amount **from the **Final Amount** to get the **Daily Interest**.

- Finally, press
**ENTER**and you will get the**Daily Interest**.

### 2. Use of IPMT Function to Calculate Daily Simple Interest in Excel

For this 2nd method, I will use **the IPMT function**. Here, I am going to use the same example that I used previously for the 1st method. But, unlike the 1st method here at first, I will calculate the **Daily Interest**. After that, with the **Daily Interest**, I will calculate the **Final Amount**.

Let’s see step by step how to calculate **daily simple interest** in Excel with the use of the **IPMT **function.

**Steps:**

- To begin with, select the cell where you want to calculate the
**Daily Interest**. Here, I selected cell**C9**. - Next, in cell
**C9**write the following formula,

`=IPMT(C6,1,1,-C5)`

Here, in the **IPMT **function, I used **C6 **as **rate, 1 **as **per **because I am calculating interest per day, **1 **as** nper **because I want to see the return after **1** day, and I selected **-C5 **as** pv **which is our present value. Now, this formula will return you the value for **Daily Interest**.

- Finally, press
**ENTER**and you will get your**Daily Interest**.

After that, you will have to calculate the **Final Amount**.

- Firstly, select the cell in which you want to calculate the
**Final Amount**. Here, I selected cell**C10**. - Secondly in cell
**C10**write the following formula,

`=C5+C9`

Here, I summed **Daily Interest **with the **Principal Amount** to get the **Final Amount**.

- Finally, press
**ENTER**and you will get your**Final Amount**.

### 3. Using FV Function to Calculate Daily Simple Interest in Excel

For the 3rd method, I will be using the same example that I used for the previous two methods. Here, I will use **the FV function** to calculate the **daily simple interest**.

Let’s see step by step how to calculate **daily simple interest** in Excel by using the **FV **function.

**Steps:**

- To begin with, select the cell where you want to calculate your
**Final Amount**. Here, I selected cell**C9**. - After that, in cell
**C9**write the following formula,

`=FV(C6,1,,-C5)`

Here, in the **FV** function, I selected **C6 **as** rate**, and **1 **as **nper **because I am calculating on a daily basis. For **pmt **I left it **blank(,,)** because we are not making any regular payments, and for **pv **I selected **-C5 **which is our present value. Now, this formula will return you the value for the **Final Amount**.

- Finally, press
**ENTER**and you will get the**Final Amount**.

- After that, select the cell where you want to calculate the
**Daily Interest**. Here, I selected cell**C10.** - Next, in cell
**C10**write the following formula,

`=C9-C5`

Here, I** subtracted** the **Principal Amount **from the **Final Amount** to get the **Daily Interest**.

- Finally, press
**ENTER**and you will get your**Daily Interest**.

## How to Calculate Daily Compound Interest in Excel

Compound interest is calculated on the initial principal amount and the earned interest from the previous period.

The formula for calculating the **Final Amount **for compound interest is,

**Final Amount = P*(1+r/n)^nt**

Where,

**P = Principal Amount**

**r = Interest Rate (Annually)**

**n = Compounding Periods (Per Year)**

**t = Time**

Here, I am going to use this generic formula to calculate **daily compound interest **in Excel.

For example, you have **$10,000** as your** Principal Amount**. Your yearly **Interest Rate** is **5.00%** and the **Compounding Period **per year is **1**. I will show you how you can calculate the **Final Amount** after **1 **year and the **Interest** you will earn. And from that interest, I will calculate the **Daily Interest** for the first year.

Let’s see step by step how to calculate **daily compound interest **in Excel by using the generic formula.

**Steps:**

- To begin with, select the cell in which you want to calculate the
**Final Amount.**Here, I selected cell**C10**. - After that, in cell
**C10**write the following formula,

`=C5*(1+C6/C7)^(C7*C8)`

Here, I **divided **the **Interest Rate **by the **Compounding Periods **and then **summed **this part with **1**. And then** raised **this whole part to the power of **Compounding Periods multiplied **by **Time**. Finally, I **multiplied **this whole part by the **Principal Amount **to get the **Final Amount**.

- Now, press
**ENTER**to get the**Final Amount**.

After that, I will calculate the **Interest (Earned in 1st Year)**.

- Firstly, select the cell in which you want to calculate the
**Interest (Earned in 1st Year)**. Here, I selected cell**C11**. - Secondly, in cell
**C11**write the following formula,

`=C10-C5`

Here, I **subtracted **the **Principal Amount **from the **Final Amount** to get the **Interest (Earned in 1st Year)**.

- Now, press
**ENTER**and you will get the**Interest (Earned in 1st Year)**.

And finally, we can calculate the **Daily Interest (For the 1st Year) **from the **Interest (Earned in 1st Year)**.

- To begin with, select the cell in which you want to calculate the
**Daily Interest (For the 1st Year)**. Here, I selected cell**C12**. - After that, in cell
**C12**write the following formula,

`=C11/365`

Here, I divided the **Interest (Earned in 1st Year) **by **365 **to get the **Daily Interest (For the 1st Year)**. **365 **is the number of days in a year.

- Finally, press
**ENTER**to get the**Daily Interest (For the 1st Year)**.

## Things to Remember

- It should be noted that in the
**simple interest**the interest earned is calculated on the**principal amount**. - Whereas, in the
**compound interest**, the interest earned is calculated on the**principal amount**and the**interest earned**from the**previous period**.
