## What Is Marginal Tax Rate?

The amount of tax paid on each additional income is known as the **Marginal Tax Rate**. With rising income, an individualâ€™s **Marginal Tax Rate** will also rise. The rate at which an additional dollar of income is taxed is known as the **Marginal Tax Rate**.

The **Marginal Tax Rate** for an individual in the **United States** is based on their tax bracket. The range of income that is subject to a specific tax rate is known as the tax bracket. For instance, a person in the 10% tax bracket would have a marginal tax rate of 10%. A person in the 15% tax bracket pays taxes at a marginal rate of 15%.

When choosing an investment, itâ€™s crucial to take the **Marginal Tax Rate** into account. How much of the profit on an investment is taxed depends on the **Marginal Tax Rate**. The investor will only keep 5% of the return after taxes, for instance, if the **Marginal Tax Rate** is 50% and the return on investment is 10%.

## 2 Ways to Calculate Marginal Tax Rate in Excel

In the following picture, I have a dataset of four columns. The first column is **Bracket**. This column has two sub-columns, **Lower Bound **and **Upper Bound**. Here, I have taken some sample tax brackets ranging from **$0 **to **$60,001** and above.

The next column is **Tax Rate **which has all the marginal tax rates ranging from **0% **to **50%**. The next two columns are **Taxable Income **and **Tax Payable**.

I will use this dataset to demonstrate the two methods of calculating marginal tax rates in Excel.

### 1. Calculate Marginal Tax Rate Without Deduction

First, I will show you calculate the marginal tax rate without deduction.

Here, I have **Gross Income Per Annum **is **$52,000 **and a **Total Deduction **is **0**.

To calculate the **Total Taxable Income Per Annum**,

- Insert the following formula in cell
**D6**.

`=D4-D5`

- Then press
**ENTER**.

The formula returns the **Total Taxable Income Per Annum** is **$52,000**.

#### Allocate Total Taxable Income

So, I have a total taxable income of **$52,000**. Now, Iâ€™m distributing this amount to the corresponding tax brackets.

- The first tax bracket
**($0 to $10,000)**gets**$10,000**. - Next tax bracket
**($10,001 to $20,000)**gets**$10,000**. - Third tax bracket
**($20,001 to $40,000)**gets**$20,000**. - And the forth tax bracket
**($40,001 to $60,000)**gets**$12,000**.

To calculate the sum of all taxable income insert the following formula in cell **E15**. Then press the **ENTER **button.

`=SUM(E10:E13)`

The formula also returns **$52,000**. This means the taxable income distribution is okay.

The basic formula for calculating **Tax Payable **is,

`Tax Payable = Tax Rate * Taxable Income`

- Now write the following formula in cell
**F10**.

`=D10*E10`

Here, **D10 **refers to the **Tax Rate **and **E10 **refers to the **Taxable Income**.

- Then press
**ENTER**.

Now drag the **Fill Handle** up to cell **F13 **to copy down the formula.

After dragging down the formula, it returns the corresponding **Tax Payable **amount for all tax brackets.

To calculate the total amount of **Tax Payable**,

- Use the following formula in cell
**F15**.

`=SUM(F10:F13)`

- Then press
**ENTER**.

The total **Tax Payable **amount is **$9,800**. So, for a total taxable income amount of **$52,000**, the marginal tax rate is **40%**.Â Itâ€™s because the 4th portion of the **Taxable Income **falls under the 4th tax bracket of **40% Marginal Tax Rate**.

### 2. Calculate Marginal Tax Rate with Deduction

Now, I will show you calculate the marginal tax rate considering all deductions.

Here,

**Gross Income Per Annum**is**$52,000**.**The total Deduction**is**$12,000**.

To calculate the **Total Taxable Income Per Annum**,

- Use the following formula in cell
**D6**.

`=D4-D5`

- Then press
**ENTER**.

The formula returns **$40,000**. So the total taxable income per annum is **$40,000**.

#### Allocate Total Taxable Income

So, I have a total taxable income of **$40,000**. Now, Iâ€™m distributing this amount to the corresponding tax brackets.

- The first tax bracket
**($0 to $10,000)**gets**$10,000**. - Next tax bracket
**($10,001 to $20,000)**gets**$10,000**. - Third tax bracket
**($20,001 to $40,000)**gets**$20,000**.

To calculate the sum of all taxable income insert the following formula in cell **E15**. Then press the **ENTER **button.

`=SUM(E10:E12)`

The formula also returns **$40,000**. This means the taxable income distribution is okay.

The basic formula for calculating **Tax Payable **is,

`Tax Payable = Tax Rate * Taxable Income`

- Now write the following formula in cell
**F10**.

`=D10*E10`

Here, **D10 **refers to the **Tax Rate **and **E10 **refers to the **Taxable Income**.

- Then press
**ENTER**.

Now drag the **Fill Handle** up to cell **F12 **to copy down the formula.

After dragging down the formula, it returns the corresponding **Tax Payable **amount for all tax brackets.

To calculate the total amount of **Tax Payable**,

- Use the following formula in cell
**F15**.

`=SUM(F10:F12)`

- Then press
**ENTER**.

The total **Tax Payable **amount is **$5,000**. So, for a total taxable income amount of **$40,000**, the marginal tax rate is **20%**.Â Itâ€™s because the 3rd portion of the **Taxable Income **falls under the 3rd tax bracket of **20%** marginal tax rate.
