How the Calculation Works (Formula Explanation)

This calculator uses simple percentage-based financial formulas to determine contributions.

1. Employee Contribution Per Paycheck

Employee Contribution = Gross Paycheck × (Employee % ÷ 100)


2. Employer Contribution Per Paycheck

Employer Match = Gross Paycheck × (Employer % ÷ 100)


3. Total Contribution Per Paycheck

Total Contribution = Employee Contribution + Employer Contribution


4. Annual Contributions

Annual Values are calculated based on pay frequency:

Employee Annual = Employee Contribution × Pay Periods per Year
Employer Annual = Employer Contribution × Pay Periods per Year
Total Annual = Total Contribution × Pay Periods per Year


Example Calculation

Let’s understand with a real-world example:

  • Gross Paycheck: $2,000
  • Employee Contribution: 6%
  • Employer Match: 4%
  • Pay Frequency: Bi-Weekly (26 periods/year)

Step-by-Step Results:

Understanding Employer Matching

Employer matching is one of the most powerful benefits in retirement planning. It means your employer contributes extra money based on your contribution percentage.

This can significantly increase your total savings over time.
