Dr. Jun Guo Shares Knowledge on Percentage-Based Budgeting
Rutgers School of Business–Camden’s Dr. Jun Guo, Associate Professor of Accounting, recently shared his expertise on personal budgeting and financial planning, offering insights into how consumers can approach popular percentage-based budgeting strategies such as the 50/30/20 and 70/20/10 rules.
While percentage-based budgeting can provide a helpful starting point, Dr. Guo emphasizes that these frameworks should serve as benchmarks rather than rigid prescriptions. Household expenses can vary significantly based on income, location and individual circumstances. Housing, childcare, healthcare and transportation costs, for example, may make it difficult for some households to follow a standard percentage-based formula.
Dr. Guo notes that percentage-based budgeting can be particularly useful for recent graduates and early-career professionals who are looking for a simple framework to determine how much of each paycheck should go toward current spending, savings and debt reduction. Establishing good financial habits early can help individuals make more intentional financial decisions over time.
At the same time, Dr. Guo stresses the importance of adapting a budget to individual priorities. Someone managing significant student debt may want to place greater emphasis on debt reduction, while a family preparing for college expenses or retirement may need to prioritize long-term savings.
Rather than relying on a rigid formula, Dr. Guo recommends approaching budgeting as a priority and cash-flow management process. Essential expenses such as housing, food, utilities, transportation and insurance should come first. Savings and debt reduction should then be treated as planned expenses rather than money left over at the end of the month. This can include building an emergency reserve, taking advantage of an employer’s retirement match, contributing to retirement accounts and paying down high-interest debt.
Discretionary spending can then be adjusted based on a household’s circumstances. During periods of inflation, income disruptions or major life transitions, Dr. Guo recommends reducing discretionary expenses first to help protect essential needs and long-term financial goals.
Dr. Guo’s perspective highlights an important principle of personal finance: there is no single budget that works for everyone. Percentage-based strategies can provide useful guardrails, but the most effective budget is one that reflects an individual or household’s income, expenses, priorities and financial goals.
Through his expertise in accounting and financial decision-making, Dr. Guo brings practical insight to the financial questions consumers face in their everyday lives.
