401(k) Calculator – Estimate Your Retirement Savings with Employer Match

What is a 401(k) Calculator ?

A 401(k) calculator is an easy-to-use tool that helps you estimate how much money you can accumulate in your 401(k) retirement account over time. By inputting your salary, contribution rate, employer match percentage, expected annual return, and investment duration, you can see how your retirement savings may grow through compounding interest.

Why Use a 401(k) Calculator?

Planning for retirement requires more than just contributing regularly to your 401(k). You need to know:

How much you should contribute each year.
How employer matching boosts your savings.
The impact of salary growth on contributions.
How compounding works over the long term.

Our calculator lets you experiment with different scenarios, helping you make better decisions about your contributions and investments.

How the 401(k) Calculator Works

When you enter your details, the calculator uses the following steps:

Annual Salary – Your starting salary before yearly raises.
Employee Contribution – The percentage of your salary you plan to contribute.
Employer Match – The percentage of your salary your employer contributes to match your contributions.
Salary Growth Rate – The percentage increase in your salary each year.
Annual Return – The expected investment return percentage.
Years to Invest – How long you will contribute before retirement.

The calculator then adds both your contributions and employer match each year, grows the balance with the expected return, and factors in salary increases.

Q3: Can my employer match exceed the IRS limit?
A: Employer contributions do not count toward your personal limit, but the total combined contribution has a separate annual cap.

Q4: How does salary growth affect my retirement savings?

Q5: Is the investment return guaranteed?
A: No. The annual return is an estimate based on historical averages; actual returns will vary depending on market performance.
