life-cycle theory
Quick Summary
The life-cycle theory, developed by economist Franco Modigliani, suggests that individuals' spending and saving habits change predictably throughout their lives. Most people earn little in their youth, accumulate wealth and pay off debt in middle age, and then spend down their savings during retirement.1
This theory helps explain personal finance and broader economic trends by recognizing distinct life phases:
* Consumption: Birth to high school graduation, with no income but needs met by others.
* Accumulation: Entering the workforce, with income but also accumulating debt for household needs.
* Consolidation: Increasing income allows for debt repayment and saving for retirement, often the peak wealth period.
* Spending: Retirement years where savings are used to support living expenses.
* Gifting: Distribution of remaining assets to heirs or charities after death.
The theory is valuable for economic forecasting and personal financial planning, acknowledging that individual experiences can vary.1
