## What Is Daily Loan Interest?

Daily loan interest is the amount of interest that needs to pay daily against a loan or a credit based on the annual interest rate as well as the loan amount. We can easily get the daily loan interest from the annual loan interest simply by dividing the annual loan interest by 365.

## Daily Loan Interest Formula

The formula used to **calculate the daily interest** against a loan or a mortgage is:

`Daily Loan Interest = (Annual Loan Balance X Annual Interest Rate) / 365`

The above formula will return the total daily loan interest amount based on the input data.

💡 Here is one thing to remember. That is the annual loan balance may not be equal to the total loan balance. Be aware of that. In the **Daily Loan Interest Calculator**, you are allowed to insert only the annual loan balance but not the total loan balance.

## Create a Daily Loan Interest Calculator in Excel

As calculating the daily loan interest requires both annual loan balance and annual interest rate, allocate two cells for them.

After that,

❶ Fix a cell where you want to return the daily loan interest. I’ve chosen cell **D7** for this instance.

❷ Then insert the following formula to calculate daily loan interest in cell **D7**.

`=(D4*D5)/365`

❸ To execute the above formula, press the **ENTER** button.

So you can use the above calculator to find the daily loan interest.

The next time, all you need to do is to input the annual loan balance and annual interest rate in cells **D4** & **D5**. And then you are ready to go.

## An Example of the Application of the Daily Loan Interest Calculator in Excel

Suppose, you’ve taken a loan of $5,000,000 from X bank for 1 year. You need to pay a 12% interest rate on the loan amount annually. Now, what is the amount of the daily loan interest that you need to pay again the amount of money that you have taken as a loan?

In the above problem,

The **annual loan balance** is $5,000,000.

The **annual interest rate** is 12%.

Now if we input these two data into the daily loan interest calculator that we’ve created, we can easily calculate the daily loan interest amount that you need to pay.

To do that,

❶ Insert the annual loan balance amount i.e. $5,000,000 in cell **D4**.

❷ Then again insert the annual interest rate i.e. 12% in cell **D5**.

After that, you will see the daily loan interest has been already calculated for you. Which is $1,644.

## Daily Compound Loan Interest Calculator in Excel

To calculate the daily compound loan interest you need to know,

**Total Loan Amount****Annual Interest Rate****Period of Loan****Payment Frequency**

The formula to calculate the compound loan interest is,

Where,

**A = The final amount that you need to pay back**

**P = Total Loan Amount**

**r = Annual Interest Rate**

**n= Payment Frequency**

**t= Period of loan**

In the calculator below, you need to insert,

❶ **Total Loan Amount** in cell **C4**.

❷ **Annual Interest Rate** in cell **C5**.

❸ **Period of the loan** in cell **C6**.

❹** Payment frequency** in cell **C9**.

After inserting all of these, you will get the amount of monthly payment in cell **C14** and in cell **C15** you will get the daily compound loan interest calculated.

To Create the daily compound loan interest calculator,

❶ Allocate cells to input **Total Loan Amount, Annual Interest Rate, Period of Loan, and Payments Per Year.** For this instance, I have used cells **C4, C5, C6, C11** respectively.

❷ After that insert the following formula in cell **C14** to calculate the **Monthly Payment** amount.

`=IF(roundOpt,ROUND(-PMT((1+C5/$C$10)^(365/$C$11)-1,$C$6*$C$11,$C$4),2),-PMT((1+C5/$C$10)^(365/$C$11)-1,$C$6*$C$11,$C$4))`

**Formula Breakdown**

**PMT((1+C5/$C$10)^(365/$C$11)-1,$C$6*$C$11,$C$4)**calculates the monthly compound loan interest amount which is**-77995.4656307853**.**ROUND(-PMT((1+C5/$C$10)^(365/$C$11)-1,$C$6*$C$11,$C$4),2)**rounds up the monthly compound loan interest amount to two decimal places. So**77995.4656307853**becomes**77995.46.****=IF(roundOpt,ROUND(-PMT((1+C5/$C$10)^(365/$C$11)-1,$C$6*$C$11,$C$4),2),-PMT((1+C5/$C$10)^(365/$C$11)-1,$C$6*$C$11,$C$4))**generates rounded version of the monthly payment if Rounding option is On. Otherwise it leaves the value as original.

❸ Then insert the following formula in cell **C15** to get the **Daily Compound Loan Interest.**

`=C14/30`

❹ Finally press the **ENTER** button.

Now to create a **Monthly Loan Interest Calculator**,

❶ Select two cells to store the annual loan balance and annual interest rate.

❷ Then choose another cell where you want to return the monthly loan interest amount. I’m choosing cell **D7** for this instance.

❸ After that, insert the following formula in cell **D7**.

`=(D4*D5)/12`

❹ Now press the **ENTER** button to execute the formula.

So this is your monthly loan interest calculator. All you need to do is to insert the annual loan balance as well as the annual interest rate. Then you are ready to go.
