📌 Example Calculation
Let’s assume the following:
- Gross Salary:
$70,000 - Your Contribution:
7% - Employer Match:
50% - Employer Match Limit:
6%
Breakdown:
- Your 401(k) Contribution: $70,000 × 7% = $4,900
- Employer Match: 50% of 6% of $70,000 = $2,100
- Total Contribution: $4,900 + $2,100 = $7,000
This clear breakdown helps you visualize your annual retirement savings growth.

🧠 Pro Tips
- Try to contribute at least enough to get the full employer match—it’s free money.
- Recalculate annually as your salary increases or employer benefits change.
- Combine this with tax-saving strategies for better outcomes.

🔐 Is My Data Safe?
Yes. The 2k Calculator is a client-side tool, which means all calculations happen in your browser. No data is collected, stored, or sent to any server.
🛠 Behind the Tool (Functionality Overview)
The calculator uses basic arithmetic functions implemented in JavaScript. Here’s what happens under the hood:
var employeeContribution = salary * (percent / 100);
var employerMatchPercent = Math.min(percent, limit);
var employerContribution = salary * (employerMatchPercent / 100) * (match / 100);
var totalContribution = employeeContribution + employerContribution;
The calculator compares your contribution to the employer match limit and uses the smaller value for employer match calculations. This ensures accurate, realistic results.
💡 Common Use Cases
- Employees comparing job offers
- HR departments demonstrating benefit packages
- Financial advisors coaching clients
- Recent graduates planning early savings
- Mid-career professionals recalibrating investments
