## 3 Suitable Ways to Calculate Interest Rate in Excel

We’ll go through four different approaches to determine the interest rate in the sections below. An example data set is provided in the image below to do the computation. We’ll calculate the **Monthly **and **Yearly Interest Rates**, as well as the **Effective **and **Nominal Interest Rates**, using formulas and functions.

### 1. Use Formula to Calculate Periodic Interest Rate in Excel

We’ll start by calculating the interest rate for a specific time period, such as months or years. We will compute the interest rate for months and then for years in the two subsections below. Follow the steps outlined below to do so.

We will apply the **RATE function **to have done it.

=**RATE**(*nper, pmt, pv, *[*fv*]*, *[*type*], [*guess*])

Here,

**Nper**(required) – total payment periods number (years, months)**Pmt**(required) – the pre-set payment amounts each period that cannot be varied over the annuity’s lifetime. It generally involves principal and interest but excludes taxes.**Pv**(required) – the present worth of the loan.**Fv**(optional) – the future worth, or the cash balance you want after the last instalment It defaults to**0**if not specified.**Type**(optional) – specifies the date on which the payments are made:- Payment is due at the end of the period if
**0**or absent (default). **1**– the first payment is required at the start of the period.**Guess**(optional) – your best guess as to what the rate may be If you leave it blank, it defaults to**10%.**

#### 1.1 Monthly Interest Rate

**Step 1:**

**To calculate the monthly interest rate**, we will select cell**F4**. In cell**F4**, type the following formula.

`=RATE(C4,-C5, C6)`

**Step 2:**

- Then, press
**Enter**to get the**Interest Rate**.

#### 1.2 Annual Interest Rate

We compute the monthly interest rate first, then multiply by **12 **to get the annual interest rate. To understand, follow the steps below.

**Step 1:**

- Type the following formula in cell
**F4**.

`=RATE(C4,-C5, C6)`

**Step 2:**

- Because years include
**12**months, multiply the previous calculation by the value of**C7**or write the following formula to get the annual interest rate.

`=RATE(C4, -C5,C6)*C7`

- Therefore, the Annual Interest Rate will be shown in cell
**F6**.

**Notes. ** Pay attention to the **C5 **cell; it is in negative form since the payment will be reduced after each transaction. It will show a #**NUM** error if you don’t put the value in negative.

### 2. Apply Formula to Calculate Effective Interest Rate in Excel

The phrase “**effective interest rate**” denotes the genuine yearly return on an investment that is obtained as a result of compounding over time. We may do it in two ways: using the conventional compound interest method or simply using a function. Follow the steps outlined below in two sections.

Here,

**i**= the rate of interest.**n**= number of the compounding periods.

#### 2.1 Use the Formula of Compound Interest

**Step 1:**

- To input the formula of effective interest rate, simply type the formula.

- The formula is,

`=(1+C4/C5)^C5 - 1`

**Step 2:**

- Then, press
**Enter**to see the results.

#### 2.2 Use the EFFECT Function

**Step 1:**

- In cell
**C8**, type the formula of the**EFFECT function**.

`=EFFECT(C4, C5)`

**Step 2:**

- Finally, press
**Enter**to get the**Effective Interest Rate**.

### 3. Convert Effective Interest to Nominal Interest

Additionally, you can get back to the **Nominal/Simple Interest Rate** from the **Effective Interest Rate**. To do so, follow the steps of applying the **NOMINAL function**.

**Step 1:**

- Firstly, enter the following formula of the
**NOMINAL function**.

`=NOMINAL(C7, C5)`

**Step 2:**

- Then, press
**Enter**to get the**Nominal Interest Rate**.
