Family Inc: Measures of Health of Family Wealth
- Original Post from Investment Moats

Personal finance books would usually teach us how to tell whether we are in a good or poor financial position.


Today, we continue with our Family Inc Series with a look at what Doug McComick recommends as metrics to measure the health of our family wealth.


You could use these metrics for a snapshot of how your family is doing. You could incorporate them into your tracking as well.


I take particular interest in this chapter to see if there are metrics that we can incorporate into my firm’s financial planning practices. You gotta keep trying to do better.


It is important for you to have an idea about your income and net wealth. And having personal income and balance sheet statements are a way to know how well you do.


We take a look at what Doug thinks we should take note of.


The Income Statement


In a financial statement, the income statement shows the readers the profit that the company or group of company earn in a year.


On a personal basis, your income statement would show your money inflows and outflows. Usually in a company’s income statement there is a separate cash flow statement. However, on a personal level an income statement or a cash flow statement is good enough.


Investment Moats recommends creating your personal cash flow statement.


Income (or Revenue) Concentration


The concentration shows the mix among the sources of income. It shows how evenly split are the two spouses’ income.


I used to have this thinking in my brain that if my friend makes $60,000 a year, her spouse also make $60,000 a year. Turns out, after more observation, for some reason the income mix is always not proportionate.


This ratio can be 50% if it is evenly split.


If you make $60,000 a year and she makes $40,000 a year, then its 60:40.


The idea of this ratio is probably more to keep in mind if your family allocates their budget according to how much each brings in.


It is also for your family to consider if you are taking up mortgage loans for example.


Surplus (Savings) Margin


Readers should be familiar with this one.


Surplus Margin = Cash Surplus / Revenue


Cash surplus is how much savings you have after satisfying all your expenses.


Doug says this is the most important metric in the page because it shows how efficiently you are able to turn labor assets into capital.


The faster you save, the faster you expand the investments in your asset management business.


The surplus margin also measure how much buffer you have, against contingencies that is inherent in you Family Inc.


A family that has a 25% surplus margin can experience a 25% decrease in income and still maintain consumption. A family with a 10% surplus margin, by contrast, would have to cut the expenses by 15%.


Does that mean that…. if my surplus margin is…. 50%, If I lost my job, I can survive for 1 year?


That is powerful indeed.


Fixed Expenses, Semi-Fixed Expenses and Variable Cost Margins


Doug explains that in the business context, this is the order of preference (top being most preferred):



  1. Variable costs

  2. Semi-fixed costs

  3. Fixed costs


The more fixed costs you have, as a percentage of your total costs, the less flexibility you have.


Doug says, if 80% of your costs are fixed, it would be impossible over the short term to reduce your consumption. That is, to reduce enough to accommodate a 25% decrease in income.


With variable costs, you can adjust quickly.


I tend to not like these terms over the years because it can be confusing. However, I absolutely get Doug’s grouping.


As an example, is your food, transport and home fixed costs, variable costs? These are technically variable but you cannot live without it. So likely these are the semi-fixed costs.


The fixed costs would be the taxes, on going medical costs, household maintenance… but even these, I can see you having a debate with me.


However, the reason for the margins is real:


If almost all your costs are fixed, then you have no flexibility. When it comes to planning for your financially independence, you need a concrete large sum as well.


Fixed plus Semi Fixed Charge Coverage Ratio


This is a comparison of your after-tax income versus (fixed + semi-fixed expenses).


The higher this ratio the greater your financial security.


Doug says if this ratio of yours is less than 1.25 times, the family is exposed to excessive risk of financial distresses.


I think this is something like the top ratio. I could invert it and it shows the ratio of income to fixed expenses.


It basically wishes your fixed expenses is small versus your income. High savings ratio usually keeps this ratio in check. If you own less stuff, your ratio might be lesser as well.


The Balance Sheet


The balance sheet, or net worth, or net wealth, or equity are referring to the same thing.


It shows your total assets, your total liabilities.


When you deduct the total liabilities from total assets, you will get total net worth/ net wealth/ equity.


You can read my personal net worth statement article here.


In this section, Doug highlights a few key measures of wealth.




  1. Family Inc Net Worth. This is total assets minus total liabilities

    1. This is broad

    2. Includes you and your spouse or (children that are not married?) expected after-tax future labor

    3. Includes your government pension value such as CPF




  2. Financial Net Worth. This is your total financial assets minus total liabilities

    1. Excludes Labor

    2. Excludes Government pension value




  3. Financial Earning Net Worth. This is financial net worth excluding the following:

    1. Assets or durable purchases that lose value, or depreciate, with normal age and use

    2. E.g. cars, trucks, appliances, electronics and furniture




  4. Investment Assets. This is the sum of all financial assets other than depreciating assets. This keep track of productive assets your business has working for you at any time


Why so much different measures?


I get this question a lot. Do you include your home? Do you include your CPF? There is a need to have these differentiation firstly to let you know what are accounting for.


The Family Inc Net Worth is likely for you to see the importance of your labor when you are starting out. When you start out, you do not have anything. However, the life time value of your labor has a substantial value. In contrast, for a person that is 56 years old, his labor value would have been less.


Financial Net Worth or Financial Earning Net Worth is closer to what we use in our financial independence planning. It eliminates the establishment risk that is of the government and also labor tends to be intangible. You have to accumulate investment assets in order for it to be tangible for some concrete planning.


Knowing how much investment assets you have is more relevant to keep track of how they are performing.


The Importance of Your Asset Composition


Doug provides some real Kung Fu here when he emphasize this: You need to take a hard look at what your assets are composed of all the time.



  1. Your labor assets will eventually be less useful over time

  2. It will be converted to other assets

  3. Different assets have different long term rate of return. For example, properties have a rate of return of 2 to 3%. Equities 5%. Your depreciating assets have a rate of return of -10%


From Family Inc

If you have allocated your assets well, exchanging it for productive capital assets, your wealth should grow well.


If it is sub-optimal, you would need to look into it.


Your Liquid Accounts


Liquid accounts that you will own will include



  1. checking

  2. cash equivalents

  3. short-term fixed income


These accounts provide your daily cash flow needs and as a safe store of value.


Months’ Contingency Capital


Months’ Contingency Capital = Liquid Accounts / Monthly Expenses


If you are unemployed tomorrow with no income, this ratio will tell the number of months your liquid assets could support your current rate of consumption.


This is basically like your emergency fund. And Doug recommends maintaining 3 months.


In this financial independence community, there are the crazy folks that would have 120 months for this!


Borrowing Capacity


This represents the max you could borrow from various sources of credit (mainly a home equity line of credit and credit cards) after deducting any outstanding balances.


In Singapore context, some sources would be personal loans and borrowing on the value of your cash value life insurance policies.


These stuff… if you are less sophisticated is like a ticking bomb. For those who know what to do with them, this can be used to blow up and sculpt a work of art.


The reason to assess this is because this also serve as contingency funds.


Months’ Borrowing Capacity


Months’ Borrowing Capacity = Amount you can borrow / Monthly Expenses


This is a variation of Month’s contingency capital.


This basically expanded your emergency fund by almost double or triple the base amount.


You do not need to draw down on it. However, if you absolutely have to, this is available.


Net Debt


Net Debt = Total Debt – Liquid Accounts


This is a refined measure of how leveraged you are.


It is what I used when assessing business as well. In the event that you are forced into a tight spot, the debt that you are worried about would be the amount you need to pay off.


For some, you can have $400,000 in debt but have $400,000 in liquid accounts, your situation is not too bad.


Net Debt to After-Tax Earnings and Net Debt to Investment Assets


There are 2 ratios here.


The first one is


Net Debt to After-Tax Earnings = Net Debt / After-Tax Earnings


This will show you how much of your income can be used to service the debt before consumption.


This is particularly sensitive to life cycles.


A young family may incur significant amount of debts to finance a home and education. When you measure it against their increasing earnings, you can assess whether these costs that you have spent are worth it.


Net Debt to Investment Assets = Net Debt / Investment Assets


By right, we should not have more debt than our investment assets. You would have more debt than investment assets, if the mortgage is on your primary residence. That is not counted as an investment assets. So this will make your ratio look….


I think if you hold a lot of investment assets, it can also show your ability to sell off the investment assets to repay the debt.


Doug recommends a net debt to after-tax earnings to be less than 6 times. I think this is not too conservative but good enough. Usually, I would use 5.


Doug recommends a net debt to investment assets to be below 1.


If you bought a primary residence with debt, your net debt to after tax earnings will be high. If it is an investment property, this ratio will go down because the rental income is part of earnings.


If your debt is consumption related, the net debt to investment assets will be high. That is not a good thing.


Liability Composition


This section will be rather short. Doug provided some advice on how he would look at debt.




  1. Maximize real estate loans over all other debt. Mortgage loans provide a sweet spot between low cost, long maturity and tax deductibility


  2. Finance significant purchases such as automobiles and education with available loans as long as the rates are less than 6%. Doug explained that these debts are attractive because of government funding for education and lenders for autos have recourse to the assets (they repossess the car if you do not pay)


  3. Compare between fixed rates and variable rates. There are no rule of thumb here. It depends on what you want

  4. Use credit cards as a loan of last resort

  5. Include your home equity line of credit as a potential source of cash to support your contingency planning program


The general idea is Doug is in favor of using leverage, but it has to be controlled and monitored. If you read this article in full, you will realize he has some monitors in place such as



  1. Months’ contingency capital

  2. Months’ borrowing capacity

  3. Net Debt to After-Tax Income

  4. Net Debt to Investments

  5. Asset Composition

  6. Fixed and Semi-Fixed Ratio to Total Cost


Conclusion


There are a few that I have not encounter before. I appreciate this book for sharing them. This book could go into this discussion because the readers tend to be more advanced.


Doug’s breakdown of the measure of wealth is good.


If you are doing your net worth tracking spreadsheet, those will be some categories to track over time. Most of my metrics look tip top but that is because my situation is a bit different.


How did your metrics look?

With regard to the concept of
"Months’ Contingency Capital = Liquid Accounts / Monthly Expenses"

Perhaps too high a number is not optimal as funds could have been deployed for other investment considerations to yield better returns. I don't have a number but 24 to 36 months seems fairly decent, buffering with inflation like 5% annual increment.

Of couse if one has already achieved a substantial amount (millions or more) then it doesn't matter. But one has to consider for unexpected events and estimated the potential cash outlay.

Thanks for sharing.
