This is the amount that you contribute to your 403(b) plan each year. Participants can contribute up to 100% of their annual income, subject to an annual maximum.

This is your annual salary from your employer before taxes and other benefit deductions. Since your contribution and any company match are based on the salary paid to you by your employer, do not include any income you may receive from sources other than your employer.

Your current age.

Age you wish to retire. This calculator assumes that the year you retire, you do not make any contributions to your 403(b). So if you retire at age 65, your last contribution happened when you were actually 64.

The starting balance or current amount you have invested or saved in your 403(b).

The annual rate of return for your 403(b) account. This calculator assumes that your return is compounded annually and your deposits are made monthly. The actual rate of return is largely dependent on the type of investments you select. For example, from December 1999 to December 2009, the average annual compounded rate of return for the S&P 500 was -0.6%, including reinvestment of dividends. From January 1970 to December 2009, the average annual compounded rate of return for the S&P 500, including reinvestment of dividends, was approximately 10.1% (source: www.standardandpoors.com). Since 1970, the highest 12-month return was 61% (June 1982 through June 1983). The lowest 12-month return was -43% (March 2008 to March 2009). Savings accounts at a bank may pay as little as 1% or less but carry significantly lower risk of loss of principal balances.

It is important to remember that these scenarios are hypothetical and that future rates of return can't be predicted with certainty and that investments that pay higher rates of return are generally subject to higher risk and volatility. The actual rate of return on investments can vary widely over time, especially for long-term investments. This includes the potential loss of principal on your investment. It is not possible to invest directly in an index and the compounded rate of return noted above does not reflect sales charges and other fees that funds and/or investment companies may charge.

The annual rate you expect your salary to increase. We assume that your salary will continue to increase at this rate until you retire.

This is an annual fee based on the balance of the account.

An employer match is in addition to your annual contributions. It is based on a percentage of your annual contributions. This range can be anywhere from 0% to 100%. An employer match is usually only for a limited portion of your salary. Please read the definition for "Employer maximum" for a detailed description.

This is the maximum percent of your salary matched by your employer regardless of the amount you decide to contribute. For example, let's assume your employer has a 50% match, up to a maximum of 6% of your annual salary. If you have an annual salary of $25,000 and contribute 6%, your annual contribution is $1500. With a 50% match, your employer will add another $750 to your 403(b) account. If you increase your contribution to 10%, your annual contribution is $2500 per year. Your employer match, however, is limited to the first 6% of your salary and remains at $750.
