Plan Your Future with Our 401(k) Calculator

See how your retirement savings can grow over time with compound interest. Our 401(k) calculator helps you estimate the future value of your account based on your current balance, annual contributions, employer match, and expected rate of return.

Key Features

Employer Match: Many employers offer to match a percentage of your contributions—this is free money! Make sure you contribute enough to get the full match.
Compound Growth: The earlier you start, the more time your money has to grow exponentially.
Interactive Chart: Visualize the powerful difference between your contributions and the investment growth over 10, 20, or 30 years.

What is a good rate of return?

Historically, the stock market has returned about 10% annually before inflation. However, for retirement planning, a conservative estimate of 6-7% is often recommended to account for inflation and market volatility.
