**Terms Related to Bank Interest Calculation**

Take a quick look at the following terms. It will help to understand the calculations.

**Principal Amount (P):** The balance at the beginning of the calculation.

**Interest Rate (R):** The rate at which interest is given.

**Period (N):** Number of periodic durations of the deposit or loan.

**Compound Interest: **Compound Interest extends to the added interests also. Banks mainly deal with compound interest.

**Simple Interest:** Simple interest works on the Principal Balance only. Banks may offer simple interest in special circumstances.

**Compound Frequency (T)**: In the case of compound interest, interests are usually compounded daily, monthly, quarterly, semi-annually, and annually. Then the number of Compounding Times will be **365**, **12**, **4**, **2,** and **1** respectively.

**Simple Interest Calculation in Excel**

We can easily calculate Simple Interest using the following formula:

**Simple Interest = Principal Amount âœ• Rate of Interest âœ• Time Periods**

Follow the steps below to apply this formula.

**Steps**

- Assume we have the following dataset.

- Now, to find Simple Interest, enter the following formula in cell
**C9**:

`=C4*C5*C6`

- You will see the result as follows:

- Now, to calculate the final balance with interest added, apply the following formula in cell
**C10**:

`=C4+C9`

- You will see the accumulated balance as shown below.

- At the end of each year, your account balance will be as follows.

**Compound Interest Calculation in Excel**

We can calculate compound interest using the formulas given below.

**Compounded Amount (A) = P âœ• (1 +Â I / T)Â âœ• N âœ• T****Compound Interest = (A â€“ P)**

Follow the steps below to apply those formulas.

**Steps**

- At first, apply the following formula in cell
**C12**:

`=C4*(1+C5/C7)^(C6*C7)`

- After that, enter the following formula in cell
**C13**to get the compound interest.

`=C12-C4`

- At the end of each quarterly period, your account balance will be as follows.

- You can use this as a template for your bank interest calculator excel sheet.

**Bank Interest Calculation in Excel for Different Interest Rates**

Assume that you need to calculate the interest rates for the following dataset.

Then follow the steps below.

**Steps**

- First, enter the following formula in cell
**C10**:

`=C9*C5*$C$6`

- Then, use the
**fill handle**tool to get other interest amounts.

- After that, apply the following formula in cell
**C11**to get the compound interest. Use the**fill handle**tool as earlier.

`=C9*(((1+C5/$C$7)^($C$6*$C$7))-1)`

- Next, to understand the above formula, just compare it to the following formula:

`= P*(((1+R/12)^(N*T))-1)`

- If you need to calculate the accumulated amounts, you can follow the earlier methods.

**EMI Calculation Using the PMT Function in Excel**

Equated Monthly Installments or EMI is a very popular phenomenon nowadays. It is a fixed monthly payment by the borrower to repay a loan. You must learn how to calculate EMI to optimize your lending or borrowing options.

Assume, you want to buy a car for **$35,000** and complete the payment in **12** EMIs at **5%** yearly interest rate.

Follow the steps below to calculate the EMI.

**Steps**

- At first, apply the following formula in cell
**C8**:

`=(((C4*C5/12)*(1+C5/12)^C6))/(((1+(C5/12))^C6)-1)`

- You can easily understand the above formula by observing and comparing the following formula.

`=(((P*R/12)*(1+R/12))^N]/(((1+R/12)^N)-1)`

Fortunately, excel also has an inbuilt function called the **PMT function** to calculate EMI.

**How does the formula work?**

The **PMT function** has the following arguments:

`=PMT(rate,nper,pv,[fv],[type])`

The arguments signify the followings:

- Rate = Rate of interest applied on the borrowing.
- NPER = Number of monthly installments per loan term which is N in this case.
- PV = Present value or Principal amount (P)
- FV = Future value after last payment which is 0 in this case
- Type = 1 or 0. The payment due at the beginning of the month indicates 1 and 0 if it is at the end of the month.

Now, letâ€™s check out this formula.

- First, enter the following formula instead in cell
**C8**:

`=PMT(C5/12,C6,C4,,0)`

- Your monthly installments will be as follows.

**Things to Remember**

- Donâ€™t forget to convert the yearly interest rate to monthly, quarterly, etc. interest rate by dividing it by the compounding times (T).
- Make sure to use the
**absolute references**properly.
