We have over twenty online retirement calculators for you to choose from. While the rules used to create these calculators can get complex, it's easy enough to see that they fall into two categories. The first set includes those that look at the general growth of retirement funds over time, while the second set includes calculators that can be used to help evaluate the various retirement planning choices you may have at work.

**retirement calculator** can help you to figure out how much money you need to save each year to retire comfortably. The calculator uses your current age, household income, current savings rate, and current retirement assets, to determine if the rate at which you're saving is sufficient to meet your retirement income needs.

**early retirement calculator** can help you to estimate how much money you will need to meet your retirement goals. The calculator uses your current age, target retirement age, household income, and current retirement assets to determine how much money you'll need in retirement savings as well as how much money you'll need to save each month to reach your goal.

**simple retirement fund calculator** to figure out how much you need to contribute each year to your retirement fund to reach your desired funding goal. The calculator uses your current age, expected retirement age, current retirement funding, desired funding at retirement, and annual return on investment to project the annual funding value.

**retirement fund balance calculator** to figure out how much money you will have in a retirement fund, given a fixed annual contribution. The calculator uses an estimate of your years until retirement, and expected annual return on the fund, to calculate the fund's balance at retirement.

**compounded growth of the retirement fund** over time. As was the case with the retirement fund balance calculator, this tool uses an estimate of your years to retirement and expected annual return on the fund as inputs.

**retirement income calculator** helps you to figure out if your retirement income expectations are realistic based on your current retirement funds and savings rate. Based on your current age and age at retirement, the calculator can estimate your total fund balance at retirement, and the annual income performance against target, with and without inflation.

**retirement withdrawal calculator** can help you figure out how much money you can withdraw from your retirement fund each month. Using your retirement age and funds at retirement, the calculator allows you to calculate a monthly income stream you can receive from this money. The calculator accommodates any pension income or Social Security you'll receive. The calculator also allows you to evaluate your monthly retirement income using a scenario that leaves money in your estate.

**retirement savings calculator** can help you figure out how much money you should save each year to reach your retirement income goals. The calculator uses your current age, household income, and current retirement assets to develop an annual retirement savings target.

**retirement withdrawal rate calculator** requires the user to supply only two inputs: a retirement portfolio mix and the desired payout period. Using this information, the calculator provides the likelihood the portfolio will successfully support withdrawal rates ranging from 3 to 8%.

**millionaire calculator** helps you figure out how much money you need to save each year to have a million dollars at retirement. The calculator uses your current age, retirement age, current net worth, and the expected annual return on investments to develop an annual savings target. Although this calculator defaults to a target net worth of $1 million, you can modify the value if you'd like to save more money.

**Roth IRA funds calculator** allows you to figure out how much retirement income you can expect from your Roth IRA account. Based on your current age and age at retirement, the calculator can estimate your total fund balance at retirement, and an annual income stream from that fund.

**traditional IRA funds calculator** allows you to figure out how much retirement income you can expect from your traditional IRA account. Based on your current age and age at retirement, the calculator can estimate your total fund balance at retirement and an annual income stream. This includes money from deposits that are made on both a before and after tax basis.

**Roth vs. Traditional IRA calculator** allows you to figure out how much retirement income you can expect from each of three types of retirement accounts on an after-tax basis.

**minimum required distribution calculator** can help you estimate your MRD for a traditional IRA, 401k, and 403b plan. By entering your current age, retirement account balance, and an expected return on investment for the account, this calculator provides an estimate of your current and future minimum required distribution payments.

**403b calculator** allows you to figure out how much money you can save in your 403b plan by retirement. The calculator will predict the 403b fund balance at retirement, a projection of the annual income you might expect from this type of account, as well as the percentage of final pay replaced by this fund.

**401k savings calculator** can help you to figure out how large your 401k plan might be at retirement. The calculator will predict the 401k fund balance at retirement age, along with the annual income you might expect from this type of account.

**IRA recharacterization calculator** can be used to estimate the recharacterization amount in a given tax year. The calculator requires four inputs: the IRA starting balance, adjustments to that balance in the computation period, the amount to be recharacterized, and the IRA closing balance. Using this information, the calculator will figure out the adjusted opening balance, net income, and recharacterization amount.

**CSRS retirement calculator** can help you figure out your retirement benefits under the Civil Service Retirement System. Using your age at retirement, years of service, unused sick days and High-3 salary, this CSRS calculator will provide you with an estimate of your Basic Annual Annuity, Annuity with Survivor benefits, and the Survivor Benefits themselves, if they apply. The technical description for the formula used by this CSRS calculator is the "General Formula."

**compound interest calculator** allows you to see the impact of compound interest on your long term investment. The calculator takes your investment or savings amount, interest rate before compounding, and investment duration to calculate the daily, weekly, monthly, quarterly, semi-annual, and annual effective interest rate. The calculator also returns the future value of the investment at each of the compounded interest rates

**Social Security benefits** under different retirement age scenarios. The calculator can accommodate three retirement ages (early, normal, and delayed), along with the expected annual benefit at each age. Using this information, along with a projected ending age to collect benefits, the tool can provide the future value of each option.

**cash out calculator** can be used to estimate the gain or loss when cashing out a retirement plan such as a 401k or 403b account. The calculator inputs consist of the retirement account balance, age of participant, income tax brackets, and the projected return on investment. The calculator's output includes the value of keeping the account versus cashing out.

**annuity calculator** can help you figure out the fixed payments you'll receive from this type of retirement investment over time. The calculator uses the starting principal balance, the interest rate received on the annuity, and the payment period to calculate annual annuity payments. The calculator also displays the declining balance of the investment over time.

**immediate annuity calculator** can help you figure out the fixed payments you'll receive from this type of retirement investment over time. An immediate annuity is a retirement income investment option typically offered by insurance companies. With this type of annuity, a large sum of money, or premium, is paid in exchange for a stream of income, which continues for as long as you live. This calculator provides the user with monthly, quarterly, as well as annual payments.

**present value of an annuity calculator** can help you figure out the worth of a stream of payments extending into the future. By taking the annual payment, number of payment periods, and the interest rate (or discount rate) of the annuity, this tool can calculate the value of that annuity stated in terms of today's dollars.

**future value** of a retirement account, as well as **three possible annuities** that could be funded using this money. Specifically, this calculator takes into consideration a fund's current balance, annual payments, and the duration over which payments will be placed into this fund. The resulting future value of this fund is then converted into three annuity terms: 20, 25, and 30 years.
