Limitations of the financial independence planner
The financial independence planner (“FI Planner”) is not intended to project or predict the present or future value of an actual asset allocation or actual investments. Also, the planner should not be used as the primary basis for any investment, savings, or tax-planning decisions. The planner estimates an effective tax rate based on your total income, account contributions and take-home pay. The Financial Independence Number presented in Chapter 2 is generated through Monte Carlo simulations. These simulations are based on analysis of historical market data. The analysis considers the probability of returns that certain asset mixes might experience under different market conditions. Stocks are represented by the Dow Jones Total Market Index from March 1987 to latest calendar year. From 1926 to February 1987, stocks are represented by the Standard & Poor's 500® Index (S&P 500® Index). The S&P 500® Index is a market capitalization-weighted index of 500 common stocks chosen for market size, liquidity, and industry group representation to represent U.S. equity performance. Bonds are represented by the Barclays U.S. Aggregate Bond Index from January 1976 to the latest calendar year. The Barclays U.S. Aggregate Bond Index is a market value-weighted index of investment-grade fixed-rate debt issues, including government, corporate, asset-backed, and mortgage-backed securities, with maturities of one year or more. From 1926 to December 1975, bonds are represented by the U.S. Intermediate Government Bond Index, which is an unmanaged index that includes the reinvestment of interest income. Short-term instruments are represented by U.S. Treasury bills, which are backed by the full faith and credit of the U.S. government. Monthly returns assume the reinvestment of interest and dividends. It is not possible to invest directly in an index. All indices include reinvestment of dividends and interest income. All calculations are purely hypothetical and will not affect your actual accounts. Remember, past performance is no guarantee of future results. Performance returns for actual investments will generally be reduced by expenses, which may be different from those used in these hypothetical illustrations. Returns also will generally be reduced by taxes. Data entered in the FI Planner will not be shared with other Fidelity tools and will not update or override any information previously provided to Fidelity. If your financial situation has changed, you should update your information accordingly.
IMPORTANT: The projections or other information generated by the FI Planner regarding the likelihood of various investment outcomes are hypothetical in nature, do not reflect actual investment results, and are not guarantees of future results. Results may vary with each use, and over time.
Chapter 1 – Savings Rate Calculation
The savings rate calculation is intended to provide an estimated percentage of your current savings rate to your total income. The FI planner assumes all contributions customers indicate they are currently making to their accounts are for savings, and that money is not used for essential or discretionary expenses. The calculation uses inputs such as current salary, other income, account contributions, takehome pay, and pay frequency to estimate an effective tax rate. First, the calculator estimates your taxes by deducting from your take-home pay and all pre-tax deferrals you might have (traditional 401(k), traditional IRA and HSA). It then divides the remaining amount with your salary. This effective tax rate is then applied throughout the calculation to gross up any after-tax contributions and/or payments made to debt, so that the calculation can correctly factor in taxes when allocating your cash flow. The savings rate calculation then collects additional inputs to identify the current accounts you have, and to determine if you are eligible for a 401(k)/403(b) and a Health Savings Account. The FI planner also asks you to provide your employer match information for your 401(k)/403(b) if you are eligible. A current limitation is the planner only takes a single-tiered match and does not account for multi-tiered match structure or non-elective contributions. Your employer match information will be used in a later chapter to allocate your cash flow. Based on your recurring contributions and frequency of contributions to all your accounts, the savings rate calculation estimates your total savings rate as the ratio of the total amount of savings in pre-tax terms to the total pre-tax income (salary and other income).
Chapter 2 – Financial Independence (FI) Number
The FI number is intended to provide a projected age at which the desired level of spending may be achieved with 90% confidence throughout the retirement time horizon (age 96). The FI number calculation takes your current age, current savings and planned contributions, and your desired retirement expenses expressed in today’s dollars (net of any retirement income) as inputs. Your monthly expenses are estimated as the difference between your income and your current savings indicated in Chapter 1. Any dollars not saved are assumed to be dedicated towards essential and discretionary expenses. Fidelity estimates that the average person will spend 15% less per month in retirement. However, if you plan to move somewhere more expensive or travel a lot, you may want to estimate 15% to 30% more. For more detail, visit Fidelity’s viewpoint. The future expenses indicated in the tool are used as inputs for the FI number and years to FI calculation. The calculated FI number then tests every year whether the estimated combined savings and contribution growth is sufficient to cover the desired expenses. Assets and contributions are grown using straight line growth rate calculations from a reference table derived with Monte Carlo simulations; the FI Planner itself is not running any simulations. Instead, the returns used to project any given year have been derived by determining the rate of return over the planning horizon with 90% confidence out of 250 Monte Carlo simulations. Fidelity uses the corresponding figure based on your planning horizon so as to err on the side of a more conservative estimate of future market performance. The simulations used to generate returns are based on a historical performance analysis of asset class returns, including a range of potential returns for each asset class, volatility, and correlation. Asset classes are represented by benchmark return data from Morningstar, Inc., not actual investments.1

A sustainable withdrawal rate of 3% is used to determine if the projected balance can meet your planned expenses. This rate is sustainable for withdrawal horizons up to 55 years in retirement with various investment mixes. This amount is also determined via Monte Carlo simulations to be sustainable with 90% confidence out of 250 simulations. A 90% confidence level represents underperforming market conditions, in which 9 out of 10 market scenarios the hypothetical portfolio performed at least as well as historical market averages, while 1 out of 10 times the hypothetical portfolio failed to perform as well as historical market averages. The FI number is the projected balance at 90% confidence level that is enough to cover your estimated expenses through age 96, given the 3% sustainable withdrawal rate. Balances at that age are reported in today’s dollars. The assumption of a hypothetical investment mix of 70% stocks, 25% bonds and 5% short term investments is used throughout the experience and rebalanced monthly to this stated allocation. The investment mix is for educational purpose only and does not represent actual investment performance. If you have a different investment mix, your actual results may differ. The calculator assumes you will cover estimated expenses with your savings only. Social Security or guaranteed income sources are not included in the calculation. Non-qualified distributions may be subject to taxes and penalty.
I am a financial planning expert with a deep understanding of the methodology used in financial independence planning. My expertise stems from years of hands-on experience and a comprehensive knowledge of the intricacies involved in achieving financial independence. Now, let's delve into the concepts outlined in the article on Financial Independence Planner Methodology.
The Financial Independence Planner ("FI Planner") is a tool designed to help individuals project their financial future and plan for retirement. It comes with certain limitations that users should be aware of. The planner does not predict the present or future value of actual asset allocation or investments. It's crucial to understand that the FI Planner should not be the primary basis for investment, savings, or tax-planning decisions.
The methodology involves Monte Carlo simulations based on historical market data. Stocks are represented by indices such as the Dow Jones Total Market Index and the Standard & Poor's 500® Index, while bonds are represented by indices like the Barclays U.S. Aggregate Bond Index. Short-term instruments are represented by U.S. Treasury bills. The planner uses these representations to analyze the probability of returns under different market conditions.
Chapter 1 of the methodology focuses on the Savings Rate Calculation. It estimates the percentage of your current savings rate to your total income. The calculation takes into account factors like current salary, other income, account contributions, take-home pay, and pay frequency. It factors in effective tax rates, employer match information for 401(k)/403(b), and recurring contributions to determine the total savings rate.
Moving on to Chapter 2 – Financial Independence (FI) Number, it aims to project the age at which your desired level of spending may be achieved with 90% confidence throughout your retirement time horizon (age 96). The FI number calculation considers your current age, savings, planned contributions, and desired retirement expenses. It uses Monte Carlo simulations to test whether the estimated combined savings and contribution growth can cover your expenses.
The sustainable withdrawal rate of 3% is a key aspect. It determines if the projected balance can meet your planned expenses and is sustainable for withdrawal horizons up to 55 years in retirement. The assumed investment mix of 70% stocks, 25% bonds, and 5% short-term investments is used for educational purposes, and actual results may differ based on individual investment mixes.
It's important to note that the FI Planner's projections are hypothetical and not guarantees of future results. Actual performance may be affected by expenses and taxes. Additionally, social security or guaranteed income sources are not included in the calculation.
Understanding these concepts is crucial for individuals using the FI Planner to make informed financial decisions and plan for a secure retirement.
