Nearly every retirement calculator opens with the same assumption: you will need about 80% of your pre-retirement income once you stop working. New research from Vanguard suggests that figure is an average almost no household actually matches.
One Rule, Three Very Different Answers
In Principles for Retirement Income, published June 2, 2026, Vanguard found that middle-income retirees do spend close to 80% of what they earned before retiring. But the number diverges sharply at both ends of the scale. Lower-income retirees spend roughly 96% of pre-retirement income, while higher earners spend as little as 40%.
Much of that spread is a Social Security story. Benefits follow a progressive formula, so they replace a far larger share of a modest wage than a high one. A lower earner has little discretionary spending to cut. A high earner was likely routing much of that paycheck into savings and payroll taxes — outflows that stop at retirement.
So the rule misfires in both directions: 80% overshoots what a $250,000 earner will actually spend, and can leave a $45,000 household short.
Essentials Do the Heavy Lifting
Vanguard also found that essentials — housing, food, transportation, health care, and clothing and personal care — make up about 85% of total annual spending for early retirees. That is the floor worth covering.
Its framework matches dependable income — Social Security, a pension, an annuity — against those costs, then funds discretionary spending with flexible portfolio withdrawals. After that reliable income, Vanguard puts a sustainable withdrawal rate at 3.5% to 4%.
The Risk Nobody Warns You About
Running out of money is the fear that dominates retirement planning. The data points to the opposite problem.
Drawing on data from the early 1990s through 2022, the Employee Benefit Research Institute finds roughly one in three retirees reach their mid-80s with their original savings fully intact — or larger — excluding home equity. Among the wealthiest retirees, 31% still held 100% of their assets or more two decades in.
"When you see so many people into their 80s still at 100%, you see people who are being way too conservative," said Craig Copeland, EBRI's director of wealth benefits research.
EBRI's Spending in Retirement Survey found the reasons: 38% were holding back for unforeseen costs, 37% felt spending down assets was unnecessary, 33% wanted to leave money to heirs, and 31% felt better keeping balances high.
Vanguard's Garrett Harbron, head of advised wealth management strategies, calls it a habit that outlives its purpose. "For 40 years of our lives, we're savers, and we're told save, save, save," he told CBS News. "While saving feels very familiar to us, spending is really kind of unknown territory."
Practical Takeaways
- Drop the generic 80% target. Estimate your own rate from your place on the income scale — nearer 96% if Social Security will be most of your income, nearer 40% if you are a high earner saving aggressively today.
- Price your essentials first. They consume roughly 85 cents of every early retirement dollar. Cover that floor with guaranteed income before deciding what the portfolio must produce.
- Sort goals into needs, wants, and wishes. Separating baseline costs from lifestyle and legacy goals shows which expenses are genuinely flexible in a down market.
- Treat underspending as a real cost. A withdrawal rate far below 3.5% is not free caution — it buys safety with vacations, gifts, and years of health you cannot get back.
