The old saying, “what matters is what’s measured”, is certainly a truism in personal finance. In order to improve on your circumstances, you have to objectively analyze what is going on so that the problems areas can be identified. The most common use-case for this rationale is a budget. I have mixed feelings on when and why a budget should be used. On the one hand, everyone needs to itemize all expenses at least once to fully see where exactly money goes. That can be a very sobering experience. On the other hand, it can be a bit tedious and unnecessary to concern yourself with where every dollar is going. Spending freely on reasonable purchases is a liberating feeling that should be enjoyed if you are still saving and progressing towards your goals. However, if you are a chronic over spender, this may not be the best mindset to embrace.
A more straightforward and quick way to examine your financial health is to use financial ratios. Ratios are an effective method in comparing your financial habits against a pre-determined benchmark in order to target any potentially category of your finances that may contain an overextension of money. There are numerous different ratios out there, but here I have chosen to highlight those that cover some of the most important areas of your finances.
Savings Ratio= Savings/Net income; .20 minimum
If you care about improving your personal financial situation, your savings rate is the most important ratio nail down. No matter what type of financial goal you have, you will have to be able to save money in order to reach it. Therefore you simply must know the amount of income that is left over after paying taxes and living expenses. Saving 5-10% of net income is certainly better than nothing, and can be a good start, however we should all really be striving to hit at least a 20% savings rate. Contributing at least 5% into the TSP is mandatory, so working towards stashing away an additional 15% should be a primary goal, bringing your total AFTER tax saving ratio to 20%.
Housing Expense Ratio= Housing Expenses/Net income; .30 maximum
Housing is the number one largest expense for most. Whether renting or paying a mortgage, the cost of a place to live is the usually the most expensive line item in all of our budgets. The good news is that because this expense is disproportionately large to the rest of our budget, it also provides the biggest opportunity to free up cash. The housing expenses ratio takes the monthly total of all housing related expenses and divides it by monthly net income. Housing expenses not only include the amount of rent or mortgage, but also utilities, property taxes and home insurance, as these are all part of the living situation. We should aim to spend no more than 30% of net income on a place to live, which would equal a ratio of .30 here.
Liquidity Ratio= Liquid Assets/Monthly Expenses; 3-6 minimum
You simply can’t get ahead when minor setbacks easily knock you down. That’s why establishing an emergency fund is one of the first orders of business in building financial stability. Having a readily accessible stash of cash is necessary for dealing with the inevitable ebbs and flows of life. The liquidity ratio serves to show how long your current lifestyle could be sustained solely off of your liquid savings (meaning investments do not count). The resulting number from the ratio is in months, so 3-6 is a solid target to shoot for. In the event of something like a job loss or any unexpected expense, this provides an adequate financial cushion to help absorb the impact, without having to immediately scramble over the bills.
Credit Utilization Ratio= Credit Amount Currently In Use/Total Credit Amount; .30 Maximum
Good credit can be a useful financial tool to have. It helps you obtain the best financing arrangements when needed, and provides an additional source of funds to be used strategically. This matters most on large purchases, like a house or a car. Credit utilization is simply the amount of credit that you are currently using out of the total amount of credit that you’ve been given. Scoring agencies like FICO typically consider you responsible in this category if you are using less than 30% of the total credit that you’ve been extended, so your score will reflect positively in that range. The lesson in responsible credit utilization applies to all areas of personal finance. Buying a fraction of what you can actually afford is typically a smart move. The smaller the loan, the less the interest that will paid over its life. Applying this approach to the largest purchases, such as houses, cars and education, can yield nice savings over the years.
Vehicle Expense Ratio= Vehicle Expenses (purchase price of car + .6 *( annual miles))/Net Income; .20 Maximum
After housing, vehicle costs are next on the list of the three largest recurring expenses for individuals. Minimizing how much you spend on a car and how much it is driven is crucial to your finances. The vehicle expense ratio accounts for exactly these two costs: how much is spent on the purchase of a vehicle, as well as the average cost per mile driven. The cost per mile is derived from an average provided by AAA that takes into account depreciation, insurance, gas and maintenance. Ideally, we would want this ratio number between .15 and .20. To achieve this, you will likely need to adhere to the cardinal financial rules of vehicle ownership. To sum up these rules: spend no more than 1/8th of your net income on vehicles and live within a 10 mile roundtrip commute of work. As long as you aren’t racking up hundreds of miles on weekends, these two points will drive your vehicle expenses way down.
Financial ratios exist to serve as a reasonable guideline in evaluating the condition of our financial standing. They should not be treated as steadfast rules, but should certainly be given reasonable consideration. If you find yourself outside of any of the recommended ranges, simply consider bringing some attention to that area of your finances. Spending more in a certain area of life that brings more value to you is perfectly fine. Just understand that it may be taking away from other financial opportunities, such as retirement. Being genuinely content with those types of tradeoffs is a big part of feeling successful with managing your money.
