In my youth, it was a revelation to Slack Investor that some people didn’t have a job – they just had income derived from assets.
I didn’t know of anyone who was independently wealthy, and thought that the normal course was to work hard till retirement age, then apply for the government pension. That’s what my parents and grandparents did. Those who have been employed since compulsory super emerged in the 1990’s can rely on industry-based super plus any extra savings.
Slack Investor has had the aim of being independently wealthy – being able to support retirement through income from assets (investments). This is the goal. However, things happen along the way, and the next best thing would be to own your own (even modest) home before retirement and get to the ‘sweetspot’ of assets. As of March 2026, this is where where a couple can have between $470 000 and $1 045 500 in retirement assets and still qualify for some government-funded aged pension to top up your income from savings.
The Path to Independent Wealth
It was reading the pioneer finance blogs of people like Mr Money Moustache that the idea of ‘Independent Wealth’ could be pursued by a normal working person. First, you have to save your retirement funds. Hopefully, the fund return will be a few percent above inflation and then you can withdraw money (based loosely on the ‘4% rule’) to live on.
‘Assuming a minimum requirement of 30 years of
portfolio longevity, a first-year withdrawal of 4 percent,
followed by inflation-adjusted withdrawals in
subsequent years, should be safe.‘ – FPA Journal – The Best of 25 Years: Determining Withdrawal Rates Using Historical Data

There is some concern that this ‘4% rule’ of thumb is inadequate as it is based upon historical market performance from 1926 till 1992 where stock market returns have been mostly good. Some advisers recommend a lower withdrawal rate of 3.3% in the initial stages – and a flexible approach to retirement spending.
The Independent Wealth Path Could be Tricky in the Next Decade
Due to the current high valuations, Vanguard is predicting a lower than average median 10-yr return for equities for the next 10 years. The Vanguard predictions are based upon past data and do not account for the productivity benefits of AI – which might justify current valuations – but they are a concern.

Slack Investor’s view is that no one really can predict the future, and there is a high volatility expressed with these equity forecasts. However, the Vanguard model 10-yr forecasts have usually been correct between the 25th and 75th percentile ranges. This gives a more rubbery forecast that Slack Investor is happier to work with. From the Vanguard Capital Markets Model forecasts issued April 2026, the predicted 10-yr percentile annual returns for each asset group are shown below. Predictions for 10-yr earnings are lower than what we have seen before.
| Asset Class | 25th Percentile Forecast | 75th Percentile Forecast |
| US Equities | 2.6% | 9.6% |
| Global (ex US) Equities | 3.1% | 9.1% |
| Emerging Markets | 0.5% | 8.7% |
| US Treasury bonds | 4.0% | 5.3% |
| US Inflation | 1.4% | 2.5% |
The ‘Independent Wealth’ path could be tricky to negotiate in the next 10 years if the forecast 10-yr returns are nearer the 25th percentile – there is a 25% chance that the returns will be lower than this. The best way to protect your funds is to hold a good portion of them in stable reserve. Slack Investor has about 30% of his funds in annuities, cash/bonds, stable dividend stocks, REIT’s, etc. Also, keep your retirement portfolio diversified across asset classes.
What Slack Investor did with the ‘4% Rule’
Before retirement: He used the ‘4% rule’ of thumb to determine the equivalence of salary and income so that he knew if he should have enough to retire.
For example, if a retirement salary of $40 000 for a couple is required, the 4% rule indicates that we should multiply this amount by 25 to get our retirement lump sum.
$40 000 x 25 = $1 000 000 in retirement funds
$80 000 x 25 = $2 000 000 in retirement funds, etc
First 5 years of retirement: Be careful here, this is where you are most prone to sequencing risk.
Sequencing risk (also called sequence of returns risk) is the danger that a significant market downturn in the early years of retirement will permanently damage your portfolio – Wealthlab
Slack Investor encountered below average returns in his 2nd and 4th year of retirement. He coped with this in two ways.
1. A dynamic spending strategy approach to net withdrawals from the retirement fund. After a good year, we would spend more on holidays. A bad year would mean a more modest approach.
2. The use of pile theory (buckets). His initial spread was 70% in investments and 30% in stable income. He has tried to keep these ratios reasonably steady by withdrawing from the over allocated pile each year.

After 5 years of retirement: Fill your boots. If the first 5 years hasn’t stressed your retirement funds, then things should be fine. There are mandated withdrawals from Super Funds (Aged 65–74: 5%, 75–79: 6%, 80–84: 7%, etc) but, if you are under age 75, re-contribution of any excess funds is a good idea.
Slack Investor has gone down the path of trying to preserve most of the capital in his retirement fund to use as a gift to the next generation or, (I hope not!) an aged care accommodation deposit. He won’t mind a bit of capital shrinkage as he gets older. He anticipates that, after the age of 70, there is more a danger of running out of time rather than money.
April 2026 – End of Month Update
Slack Investor remains IN for Australian index shares, the US Index S&P 500 and the FTSE 100.
All markets had a rebound in April. The rise was modest for the ASX 200 (+2.2%) and the FTSE 100 (+ 2.0%). The ‘Crazy Brave’ US market had strong growth (+ 9.5%) on the possibility of an Iran War ‘deal’ and a return to ships passing freely through the Strait of Hormuz. At the time of writing, this hasn’t happened yet.
All Index pages and charts have been updated to reflect the monthly changes – (ASX Index, UK Index, US Index).
