A detailed retirement calculator will take into account taxes, pension income, expenses, Social Security and numerous other factors that will affect your retirement income.

Contrast that with a simple, one page retirement calculator which can help you develop a general idea of how long your money will last depending on how much you withdraw.

See my series of retirement calculator reviews or browse the list below to find both detailed and one page retirement income calculators.

(Keep in mind, all the online retirement calculators I can find do not provide the level of detail you need as you get within ten years of retirement.)


ESPlanner Basic
Most of the free retirement calculators don't accurately tax different sources of income and don't allow you to input different retirement dates for one spouse versus another. The exception to this is ESPlanner Basic. Although not the most visually appealing, nor the most user-friendly, from an accuracy standpoint, it is the best free retirement calculator I have come across.

    Social Security Retirement Calculators
    The problem with traditional retirement calculators is they don't provide advice. One of the decisions you will make that will have a big affect on how much retirement income you have is how and when you decide to collect your Social Security benefits. Use a Social Security calculator to help you with this decision.


    Another problem with traditional retirement calculators is they often do not give you an accurate picture of what your after-tax retirement income will be. It is likely you will pay taxes in retirement and the amount of tax you pay will depend on many factors that are often missed by retirement calculators.

    Although a retirement calculator is a good start, an experienced retirement planner can take those calculations and then provide advice by showing you ways to increase your after-tax income, not by choosing better investments, but by using tax and Social Security rules to your advantage.


    In lieu of a retirement calculator, for a quick calculation you can use a math rule called the Rule of 72 to quickly see how long it will take you to double your money given a particular rate of return.
