Retirement calculators and spending

 categorizes retirement calculators by the type(s) of retirement spending models they use. For a detailed discussion about the various types of retirement spending models, refer to the articles in the Retirement spending wiki series (Sidebar to the right).

Introduction
There are many other criteria besides spending that can be used to categorize retirement calculators. Examples of these criteria include: tax calculation method, asset classes included as investments, Social Security claiming guidance, types of tax-advantaged savings plans, and types of annuities. The restriction of these tables to just spending model categories does not imply that this aspect of the calculation is any more important than the others mentioned!

One of the most important characteristics of a retirement calculator is the method used to simulate potential future investment returns. Because of this importance a column has been added in each table that lists the method(s) used by each calculator.

Abbreviations used in the calculator tables
These abbreviations are used to keep the tables compact while still maximizing the amount of descriptive information they contain.

Runtime Environment Abbreviations. These are used to indicate computational requirements for using a calculator.
 * Web = Runs only through a web browser
 * Win = Runs only under MS Windows
 * Xcel = MS Excel spreadsheet

Calculator Type Abbreviations. These are used to categorize the calculator's approach to estimating future growth in retirement savings.
 * Det = Deterministic. The calculator uses fixed, user selected future stock and bond returns.
 * HRet = Historical Returns. The calculator uses historical stock and bond returns as a guide.
 * HStr = Historical stress test. The calculator uses historical U.S. stock and bond returns (and sometimes the corresponding inflation) starting from one or more specific years in the past to Stress Test the retirement plan for worst case scenarios.
 * MC = Monte Carlo. The calculator uses a Monte Carlo model of stock and bond investment returns as a guide.

Initial Retirement Spending Abbreviations. These are the potential types of spending models that could be used to describe retiree spending at the start of retirement.
 * RepR = Replacement Rate
 * STot = Single Budget, total spending only
 * SWks = Single Budget, worksheet included
 * DTot = Dual Budget, total spending only
 * DWks = Dual Budget, worksheet included.
 * N/A = Calculator doesn’t allow user to independently set spending in retirement.

Spending Model as Retirement Progresses. These are the different methods used for modeling spending.
 * Constant-Real - starts at an amount that is adjusted for yearly inflation.
 * Retirement Stages - two or more different constant or real spending levels.
 * Returns Dependent - spending adjusted depending upon earnings returns.
 * Flexible Spending - two or more spending categories.
 * Life Cycle - spending varies according to stages of life.

Free retirement calculators
Free retirement calculators are widely available on the Internet. As seen in the table below, the majority of these caclulators only incorporate a Constant Real spending model as retirement progresses. For the average retiree this type of spending model does not offer as realistic a description of spending patterns as the other model types (see discussion in Constant (real) Spending Models).

Purchased retirement calculators
