Week 1 Day 6: Budgeting in Retirement

When you are working, your income stream is a paycheck. In retirement, it shifts to Social Security, portfolio withdrawals, dividends, maybe part-time work. The principle does not change: match your spending to your income stream. Your discretionary dollars still determine how much flexibility you have.

Retirement budgeting has one critical difference: your income has a ceiling. There is no raise coming. No bonus. No overtime. This makes the budget even more important, not less. You need to know exactly what comes in and exactly what goes out. The good news: many expenses drop in retirement. No commute. No work clothes. Possibly no mortgage. The bad news: healthcare costs usually rise. The budget helps you see the trade-offs clearly. Many retirees find they spend 70-80% of what they spent while working, but the mix changes dramatically. The budget is how you navigate that shift without anxiety.

The Employee Benefit Research Institute's Retirement Security Projection Model shows that retirees who actively budget have a significantly lower probability of running out of money than those with equivalent portfolios who do not budget. The reason is behavioral: budgeters catch overspending early. A retiree withdrawing 5% instead of 4% may not notice the difference month-to-month, but over a decade the extra 1% can reduce portfolio longevity by 7-10 years. Regular budget reviews -- quarterly at minimum -- are the early warning system that keeps withdrawals sustainable.
