How to Enter an Excel Formula With Price Plus Tax: A Step-by-Step Guide

Entering a formula in Excel that calculates the price plus tax is a straightforward process. First, input the price of the item in a cell. Next, multiply the price by the tax rate (expressed as a decimal) in a separate cell. Finally, add the calculated tax to the original price to get the total cost.

After completing this action, you’ll have the total cost of the item, including tax, displayed in your Excel spreadsheet. This can help with budgeting, expense tracking, and financial reporting.


When it comes to crunching numbers, Excel is a powerhouse tool that can make life a whole lot easier. Whether you’re running a business, organizing personal finances, or just trying to figure out how much that new gadget will actually cost with tax, Excel has got you covered. But, let’s be honest, formulas can be intimidating if you’re not familiar with them. And when it comes to adding tax to a price, you want to make sure you’re doing it right – nobody likes being off the mark with money matters.

So, why is it important to know how to enter a formula for price plus tax in Excel? For starters, it ensures accuracy. No more second-guessing or using a calculator outside of Excel. It also saves time. Once you set up the formula, you can reuse it for multiple items or even across different spreadsheets. Plus, it’s a skill that’s relevant to pretty much anyone dealing with numbers – from students working on a project to professionals managing a company’s finances.

Now, let’s dive into the step-by-step process of creating this formula. It’s easier than you think, and once you’ve got it down, you’ll be able to handle Excel like a pro!

How to Enter an Excel Formula With Price Plus Tax

The following steps will guide you through creating a formula that will calculate the price of an item with tax included.

Step 1: Enter the price of the item

Input the price of the item into a cell (e.g., A1).

Entering the item’s price is your starting point. Make sure to input it as a number without any currency symbols, as Excel will treat these symbols as text.

Step 2: Input the tax rate

Type the tax rate as a decimal in another cell (e.g., B1).

If the tax rate is 7%, you’ll enter it as 0.07. Remember, converting percentage to a decimal is crucial for the formula to work correctly.

Step 3: Create the formula to calculate tax

In a new cell, enter the formula =A1*B1 to calculate the tax amount.

This formula multiplies the price by the tax rate, giving you the tax amount that needs to be added to the original price.

Step 4: Add the tax to the original price

Finally, in another cell, create the formula =A1+(A1*B1) to get the total price including tax.

This formula adds the calculated tax to the original price, giving you the final amount you’ll pay for the item.


AccuracyBy using an Excel formula, you eliminate the risk of human error that comes with manual calculations.
Time-savingOnce set up, the formula can be copied and used for multiple items, saving you from repetitively entering the same calculations.
VersatilityThis formula isn’t just for calculating tax. It can be used for other types of percentage-based calculations, like discounts or commissions.


Initial Learning CurveFor those new to Excel, there might be a bit of a learning curve when it comes to understanding how formulas work.
Tax Rate ChangesIf the tax rate changes, you’ll need to remember to update the formula accordingly, which can be a hassle.
Over-relianceRelying too much on Excel can lead to complacency, and it’s important to understand the math behind the calculations in case you need to verify results without Excel.

Additional Information

Knowing how to add tax to a price using an Excel formula is a valuable skill that can streamline financial tasks. But beyond this specific application, understanding how Excel formulas work opens the door to a world of possibilities. With formulas, Excel can become a dynamic tool for analyzing data, making projections, and automating tasks.

Remember to always double-check your formulas for accuracy. One small error can throw off your entire spreadsheet. Additionally, while Excel is a powerful tool, it’s not foolproof. It’s good practice to occasionally do manual checks or use other methods to confirm your results.

Lastly, keep in mind that Excel has a range of functions and capabilities beyond simple formulas. Explore the various functions available, like SUM, AVERAGE, or VLOOKUP, to enhance your Excel skills further.

Frequently Asked Questions

What if I need to calculate the price plus tax for multiple items?

You can use the same formula for multiple items by copying the formula to other cells. Just make sure that your cell references are correct.

How do I format the result to show a currency symbol?

Right-click on the cell, choose ‘Format Cells,’ go to the ‘Number’ tab, and select ‘Currency’ to format the result with a currency symbol.

Can I use this formula for discounts instead of tax?

Absolutely! Just replace the tax rate with the discount rate (as a decimal), and the formula will calculate the discounted price instead.

What if the tax rate is different for different items?

You’ll need to input different tax rates in separate cells and adjust the formula to reference the correct tax rate cell for each item.

Is there a way to make the tax rate automatically update in the formula if it changes?

You can use absolute cell references (e.g., $B$1 instead of B1) to ensure the formula always references the same tax rate cell, even when copied to other cells. Then, you only need to update the tax rate in that one cell.


There you have it – a simple yet effective way to calculate the price plus tax in Excel. It’s a skill that can make a world of difference in managing finances, both personally and professionally. But remember, Excel is more than just a calculator. It’s a tool that, when used to its full potential, can provide valuable insights and streamline complex tasks.
