Formula Used in 401K Calculation
This calculator uses a combination of contribution and compound growth formulas.
1. Annual Contribution
Annual Employee Contribution = Salary × (Contribution Rate ÷ 100)
2. Employer Match
Annual Employer Contribution = Salary × (Employer Match ÷ 100)
3. Total Contributions Over Time
Total Contributions = Annual Employee Contribution × Years
Total Employer Match = Annual Employer Contribution × Years
4. Total Principal Investment
Total Principal = Employee Contributions + Employer Match
5. Future Value with Compound Growth
FV=P(1+r)n
PV
$
r
%
n
PV is starting amount; r is rate; n is number of periods.
FV=PV(1+r)n=1(1+0.05)20=2653.3dollars
Where:
- FV = Future Value
- P = Total Principal
- r = Annual Growth Rate (decimal)
- n = Number of Years
6. Investment Growth
Growth = Future Value − Total Principal
Example Calculation
Let’s understand with a real-life example:
- Current Age: 30
- Retirement Age: 60
- Salary: $60,000
- Contribution Rate: 10%
- Employer Match: 5%
- Growth Rate: 7%
- Years: 30
Step-by-step breakdown:

| Annual Employer Match | 60,000 × 5% | $3,000 |
| Total Annual Contribution | 6,000 + 3,000 | $9,000 |
| Total Contributions (30 years) | 9,000 × 30 | $270,000 |
