Tax Shield Calculator


What is the tax shield?

Tax shield is a reduction of taxable income due to decreasing it by deductible expenses like interest, amortization and depreciation. Those deductions lower the income tax the company or individual has to pay in a given year.

The tax shield is an incentive for investing, because it allows one to receive tax benefits before an investment starts to generate profits. 

Tax deduction allows a company to increase its Net Operating Profit After Tax and therefore helps them to grow faster.

How to calculate the tax shield?

The calculation of tax shields is pretty simple. It is important to understand the concept of deductible expenses and how the tax rate is applied. 

Deductible Expenses

The deductible expenses are all the necessary costs you need to cover to operate your business.  

Tax rate

The income tax rate may vary between states. That's why you need to make sure you input valid values before you calculate the tax shield value.

The tax shield formula

If you wish to calculate tax shield value manually you should use the formula below:

Tax_shield = Deductible_Expenses * Tax_rate


If you wish to calculate the value of a tax shield you may use this tax shield calculator or work out the value manually like we do in the following example.

Deductible_Expenses = $50,000
Tax rate = 35%
Tax_shield = Deductible_Expenses * Tax_rate = $50,000 * 35% = $17,500
