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:
| Description | Calculation | Result |
|---|---|---|
| Employee Contribution | 2000 × 6% | $120 |
| Employer Match | 2000 × 4% | $80 |
| Total Per Paycheck | 120 + 80 | $200 |
| Employee Annual | 120 × 26 | $3,120 |
| Employer Annual | 80 × 26 | $2,080 |
| Total Annual Savings | 200 × 26 | $5,200 |
This example shows how consistent contributions can build a strong retirement fund over time.
