Wondering how much money you'll need to retire? How about how long you can live on what you have now? So many questions! There are four main variables that affect your retirement income from your investments:
Basic Assumptions
* Wealth: Net worth at time of retirement. Not added to after retirement.
* Interest: Per year (not including compounding), after inflation, paid continuously.
* Expenses: The fixed amount you draw out each month, paid continuously.
* Length: Years of retirement.
With this little app you can easily explore "what if" scenarios involving these variables.
Instructions:
The selected row is the variable the applet is solving for. By default the "Expenses" variable is selected. This means that you can see how much you can draw each month depending on the values you enter for the other three. For example, if you expect a 25 year retirement and expect to earn 5%, you can input those values and then adjust the "Wealth" slider to see how much money you will be able to live on each month depending on your net wealth at retirement.
You can select the "Wealth" row in order to see how much you'll need to save in order to retire with a particular desired monthly disbursement. You can solve for "Interest" to see what sort of interest rate you'll to meet your goals, and you can solve for "Length" to see how many years your savings will last given the other parameters. Play with the app for a while and you should get the idea of how to answer many other interesting "what if" scenarios.
You can even use the app for purposes other than just retirement. For instance, if you are an officer in a start-up or own a small business and are considering whether to take out a big loan or a round of venture capital funding, you can calculate how long of a runway it will provide, or how much you can spend each month with a runway of a given length.

不知道多少钱，你就需要退休？怎么样，你可以住在你现在有什么多久？这么多的问题！有迹象表明，影响你的退休收入从投资四个主要变量：
基本假设
    *财富：在退休时的净值。不添加到退休后。
    *息：每一年（不包括复利），通货膨胀调整后，继续支付。
    *费用：你每个月抽出固定的金额，持续支付。
    *长度：年退休。
有了这个小应用程序，你可以轻松地探索“假设”场景涉及到这些变量。
说明：
所选择的行是该小程序被求解的变量。默认情况下，“费用”变量选择。这意味着，你可以看到有多少你可以每??个月汲取根据您输入的其他三个数值。例如，如果你希望25年退休，并希望赚取5％，你可以输入这些值，然后调整“财富”滑块，看看多少钱，你就可以把每一个月取决于你的净财富在退休。
你可以为了看看有多少，你需要保存，以退休与特定的期望每月支出中选择“财富”行。你可以解决的“兴趣”，看看什么样的利率，你会满足你的目标，你可以解决的“长度”，看看有多少年储蓄将持续给其他参数。玩了一段时间的应用程序，你应该得到怎样回答很多其他有趣的“假设”场景的想法。
你甚至可以使用该应用程序的目的不仅仅是退休等。例如，如果你在一个初创的人员或拥有一家小型企业，并考虑是否采取了一个大的贷款或轮风险投资资金，可以计算出跑道长它将提供，或如何多少可以每月花费具有给定长度的跑道。
警告：我不作任何保证，对这个应用程序的实用程序或准确性。这仅仅是用于获取可能的退休情景一个粗略的工具，而不是专家建议退休的专业人员更换。

1.4 Only show description for selected row.
1.3 Really fixed button labels.
1.2 Hopefully fixing bug where sometimes all radio buttons show the same label.
1.1 Hiding the disabled slider of the selected row because people attempt to move it anyway. I still show it while the user is operating the other sliders but hide it again when they stop.
