Ask most people in their 50s whether they are on track for retirement and you will get variations of the same answer: “I think so.” “We’re doing okay.” “We probably should have started earlier.” Almost nobody can give you a number — a specific, calculated target that tells them where they need to be.
This vagueness is understandable. Retirement planning involves estimating an uncertain future: how long you will live, what inflation will do, how markets will perform, what your health costs will be. But the vagueness has a cost, particularly for adults in their 50s who are also managing competing financial demands — including pressure to help their adult children. Without a clear picture of what you need, it is nearly impossible to know how much you can afford to give away.
Starting With Spending, Not Savings
The most common mistake in retirement planning is leading with savings — “How much do I have?” — rather than spending — “How much will I need?” Your savings target is derived from your spending needs, not the other way around. Start with the spending question.
What will your life in retirement actually cost? Begin with your current monthly spending and adjust for retirement realities: you may spend less on commuting, work clothing, and lunch out. You may spend more on travel, healthcare, hobbies, and leisure. Many financial planners use a rule of thumb that retirement spending is 70–80% of pre-retirement spending — but this varies enormously by individual. Some people spend more in active early retirement than they did while working. Others spend significantly less.
Track your actual current spending for three months before making assumptions. The specificity will surprise you — and it will give you a much more reliable baseline than any rule of thumb.
The 4% Rule and What It Actually Means
The 4% rule — withdraw 4% of your portfolio in year one of retirement, then adjust for inflation annually — is a useful planning shorthand, not a guarantee. It is derived from research on historical market returns over 30-year retirement horizons. By this guideline, if you expect to spend $70,000 per year in retirement and will receive $25,000 per year in Social Security, you need your portfolio to generate $45,000 per year. Using the 4% rule, that implies a portfolio of approximately $1.125 million.
Your number will shift based on when you retire (earlier retirement means a longer horizon and a lower safe withdrawal rate), your asset allocation, and your flexibility — retirees who can reduce spending in bad market years have more margin than those with fixed expenses.
Sequence of Returns Risk: The Risk Nobody Talks About
One of the most underappreciated risks in retirement is sequence of returns risk — the danger of experiencing bad market returns early in retirement. Because you are withdrawing money each year, a bear market in your first five years of retirement can permanently impair a portfolio in ways that the same bad market in year 20 would not. When you sell assets at depressed prices to fund living expenses, those shares cannot participate in the eventual recovery.
This risk has a direct implication for how you think about helping your children. A large financial transfer to a child in the early years of your retirement — precisely when sequence of returns risk is highest — can materially worsen your financial position. If markets then decline, you may be forced to sell even more at depressed prices. The combination can permanently reduce the sustainability of your retirement income.
Building In Buffers
A realistic retirement plan accounts for four categories of financial uncertainty: longevity risk (living longer than expected), healthcare costs (including potential long-term care), inflation (particularly healthcare inflation, which runs higher than general inflation), and unexpected large expenses (home repairs, family emergencies, helping a child through a genuine crisis).
Building a buffer into your retirement number — planning to 95 or even 100 as a lifespan, using a 3.5% rather than 4% withdrawal rate, or holding one to two years of expenses in cash or short-term bonds — costs something in terms of apparent accumulation. But it provides meaningful protection against the scenarios that devastate underprepared retirees.
It also changes how you answer requests for financial help. If you know your plan has a genuine buffer, you can give from that buffer with relative confidence. If your plan is tight, you know that even modest generosity carries real risk — and that honesty with your children is a service to both of you.
The Tools Worth Using
Several free and low-cost tools can help you model your retirement picture with more precision than a rule of thumb:
- FIRECalc (firecalc.com): A free tool that runs your retirement scenario against every historical market sequence since 1871, showing you the percentage of scenarios in which your money lasts.
- NewRetirement (newretirement.com): A more comprehensive planning tool with a free tier that allows detailed scenario modeling.
- Your Social Security statement (ssa.gov): The projected benefit at various claiming ages is an essential input for any retirement calculation.
- A fee-only financial planner: For a one-time planning session or annual check-in, a planner who charges by the hour rather than by AUM (assets under management) can provide analysis worth far more than the fee. NAPFA.org maintains a directory of fee-only advisors.
Knowing your number is not about anxiety. It is about clarity. And clarity is the foundation of every other financial decision you make — including the ones about your children.
