Calculate Net Pay Using Subtraction and SUM Formulas
Use standard arithmetic formulas to deduct individual tax amounts from the gross salary.
This method is straightforward and involves deducting the sum of your Social Security and Medicare taxes directly from the gross pay cell.
Place Gross Salary in cell A2, Social Security in B2, and Medicare in C2.
In your target Net Pay cell (e.g., D2), type =A2-(B2+C2) or =A2-SUM(B2:C2) and press Enter.
Select the Net Pay cell, navigate to the Home tab, click the Number Format dropdown, and choose Currency or Accounting.
Fix One-Cent Differences Using the ROUND Function
Use the ROUND function to prevent floating-point and hidden decimal discrepancies that cause a one-cent error.

Frequently Asked Questions
Why is my Excel net pay calculation off by one penny?
Excel stores numbers with up to 15 decimal places of precision, even if you format the cell to display only two decimals. When you subtract these unrounded numbers, the hidden fractions can add up to a visible one-cent difference. Use the ROUND function to lock values to exactly two decimal places.
What are the standard Social Security and Medicare rates to use in my formulas?
Typically, the employee Social Security tax rate is 6.2% and the Medicare tax rate is 1.45%. You would multiply the gross salary by 0.062 and 0.0145 respectively. Always verify current rates with the IRS before finalizing payroll.
Can I automatically calculate these taxes for an entire column of employees?
Yes. Once you write the net pay formula for the first employee in the top row (e.g., =A2-(B2+C2)), you can double-click or drag the fill handle at the bottom-right corner of the cell down the column to automatically apply the calculation to all other employees.
