FINANCIAL INDEPENDENCE

The Financial Independence chart in the various Portfolio tools  shows the full range of working years historically required to accumulate enough savings to never have to work again.  Use this to study the effects of asset allocation on both sides of your retirement goal, to estimate your retirement date, or to learn just how important your savings rate is to your future financial security.

How To Interpret The Chart

The Financial Independence chart is essentially a mashup of the Portfolio Growth and Withdrawal Rates calculators.  It calculates the 30-year perpetual withdrawal rate for the portfolio, maps every growth path for the same portfolio, and shows the range of working years required to fully fund your retirement account.

Perhaps the most important takeaway from the chart is that your absolute account value and spending level are irrelevant to the calculations.  No matter whether you make $30k a year or $1mm a year, the only number that really matters is the percentage of your net income that you save.  While the default savings rate is 30%, try playing with that amount and you’ll quickly see the value of higher savings rates.  Veteran investors with an established nest egg can also enter the years of expenses they’ve already saved up rather than starting from zero.

Depending on the portfolio, you may also see dashed gray lines.  These indicate that the calculations include start years with incomplete data where the returns are only estimated based on the best numbers I have available.

 

Assumptions

1) The withdrawal rates are calculated using the same methodology as the Withdrawal Rates calculator. /// More Info ///

2) The Financial Independence calculator uses the applicable 30-year perpetual withdrawal rate for a given asset allocation.

3) The savings goal is calculated from the single lowest withdrawal rate on record for the specified portfolio.  Accumulation paths then model the inflation-adjusted portfolio accumulation using every possible start year since 1970.

4) The asset allocation is constant (subject to normal annual rebalancing) across both accumulation and retirement.

5) The lowest number of working years is the one where at least one accumulation run met the final goal. The highest number of working years is the first one where all accumulation runs met the final goal.

6) The savings rate is assumed to be based on net income after taxes.

7) Returns include reinvested dividends.

8) Returns ignore taxes.  Individual tax situations are far too complex for a tool like this to model.

 

Disclaimer

Note that the calculator does not look at full consecutive 60-year accumulation and retirement market sequences, and any single historic lifetime is impossible to accurately represent in the data set. That’s not the goal, however, as the chart displays the full range of accumulation paths using every possible start year to fund the all-time minimum withdrawal rate. The purpose of the calculator is to assume your own sequence of returns will be unknown and to paint the big picture rather than represent any single investing lifetime with precision.

That said, be careful not to fall in love with specific assets or portfolios that have done well since 1970 but may not perform as well over longer timeframes. A lot can change over an investing lifetime, and past performance is no guarantee of future returns. Diverse portfolios with several uncorrelated assets are generally recommended over concentrated portfolios even with great numbers, and a good investment plan requires more consideration than simply a desirable calculator result.

The numbers do not account for taxes.  Taxes may vary significantly between individual investors, and careful tax planning is recommended when depending on money in tax-deferred accounts.  Considering taxes, your personal withdrawal rate may be lower than the one shown, and your working years may be longer.
