Incurring debt shouldn’t be avoided or feared, but it should be used intentionally, with a defined purpose and an absolute ability to service the debt.
The most common, purposeful use of debt is a mortgage loan for your primary residence. Incurring mortgage debt makes buying a home affordable, and the monthly payments provide the buyer with an opportunity to build equity in an asset rather than being a pure expense (as in rent payments).
With proper financial analysis, using debt as leverage to purchase a productive non-financial asset can create excellent opportunities for capital appreciation and/or income-generation.
Two grey areas for incurring debt are vehicle loans and student loans. Planning ahead and saving to purchase a vehicle or pay cash for college are the optimal strategies.
However, these are big, and increasingly necessary, one-time expenses that often require payment with borrowed funds.
Vehicles
Vehicle purchases are essentially lifestyle decisions. People pay extra for the intangible status benefits beyond their basic transportation needs. If they can afford to include a permanent transportation expense line in their household cash budget, then it doesn’t really matter if they lease their vehicle or take out a loan.
If they’re going to replace their vehicle every three years, they’re probably better off leasing than buying.
A purposeful use of a vehicle loan is to pay it off, on-time, over five years, then drive the vehicle (for free) for three to five more years. Of course, this is also a lifestyle decision.
Student Loans
Ideally, student loans are incurred to get a degree and gain employment with enough income to pay the loan off over its ten-year term. However, there’s no assurance that sequence of events will occur.
Many students never complete their college degree programs or are unable to get a good job after graduating. As of April 2025, nearly one-third of all student loan borrowers were over 90 days past due.
If a household has student loan debt remaining from the parents’ college days, protect your credit rating by continuing to pay it off. If parental student loans are expected to be used to fund their children’s college expenses, bake the loan repayment into your cash flow forecast.
Credit Cards
Credit cards should be used only for convenience and transactional simplicity, with their balances paid off every month.
Revolving credit card debt and home equity loan balances are the result of negative household cash flow. Their existence contributes to a downward spiral of finances and life.
