Charleston 401k Contribution Calculator

Use our free 401(k) Contribution Calculator to estimate how your retirement savings could grow based on your salary, contribution rate, employer match, and investment performance. This tool illustrates how long-term investing and compounding returns can turn steady contributions into a substantial nest egg.

🔧 How to Use the Calculator

This calculator is simple and intuitive. Here’s how to get started:

• 🧾 Annual Salary ($)

  • Enter your current gross annual salary before taxes.

• 💰 Your Contribution (% of salary)

  • Input the percentage of your salary you plan to contribute to your 401(k). Many people aim for 10–15%.

• 👔 Employer Match (% of salary)

  • If your employer offers a matching contribution (e.g., 3% or 5%), enter that here. Matching is essentially free money for your retirement.

• ⏳ Years to Grow

  • Enter how many years you plan to keep contributing and let the investment grow — typically until retirement.

• 📈 Expected Annual Return (%)

  • Estimate your annual investment return. A typical long-term stock market return after inflation is around 7%.

• 🧮 Click “Calculate Projected Balance”

  • We’ll estimate your future 401(k) balance based on your inputs and the magic of compounding.

💡 What Is Compound Interest?

Compound interest means your contributions earn investment returns — and then those returns generate even more returns over time. The longer your money stays invested, the more powerful this compounding becomes.

📊 What the Result Shows

After clicking the “Calculate” button, you’ll see:

• Total projected 401(k) balance after your investment period

• The effect of your contributions and your employer’s match

• The impact of annual investment growth

This estimate gives you a simple projection of how consistent saving and investing can fuel your retirement.
