What Does Your 401(k) Balance Leave Out of Your Retirement Picture?
You check your 401(k), notice the balance, and wonder how much closer you are to retirement. It may be the account you know best because you’ve watched it grow through years of contributions.
That balance matters. By itself, though, it can’t tell you whether you can afford the retirement you want. Other resources may help cover your spending, but some may not become available until later. Looking at what’s available—and when—can reveal possibilities or gaps that one account leaves out.
What will you need that account to support?
Begin with the life you’re considering: the home you expect to maintain, regular spending, and the activities or responsibilities that matter to you. FINRA’s guidance connects investment goals with their cost, time frame, and available resources. [1] A savings target becomes more useful when you know what it needs to fund.
Perhaps you want to stop working before a future benefit begins. Your savings would need to help cover spending before the benefit begins as well as afterward. Or a confirmed pension may cover part of your ongoing spending, changing what you need from investments.
Comparing your 401(k) balance with a round-number milestone won’t tell you enough about either situation. What will you need from that account once you’ve considered your other resources and the commitments they already support?
What else belongs in the picture?
Other retirement accounts, savings, and confirmed benefits may contribute. Look at what each can provide rather than adding everything into one total. Retirement accounts differ in their features, taxes, fees, and available investments. [2] The balance alone doesn’t tell you what using that money would mean for you.
Consider regular income alongside your account balances, but don’t add a monthly payment to an account balance as though they were the same kind of resource. A monthly pension can help pay ongoing expenses; it is not another account you can necessarily withdraw at will. If the plan offers a lump sum instead, compare the two options separately rather than counting both as available.
Ownership and purpose matter as well. Money already set aside for another commitment may not be available for the retirement you’re considering. A home can be valuable without providing spending money under your current plans. An expected inheritance remains uncertain. The fuller picture should include limitations as clearly as benefits.
When does each resource begin helping?
Suppose you are considering leaving work before starting Social Security. The benefit can support later spending, but it does not pay the bills before it starts. Claiming age also affects the monthly amount, so timing belongs in the comparison. [3] Timing alone doesn’t tell you which claiming date is right for you.
The following comparison assumes a future benefit begins as planned. It shows how much you need from savings can change, without assuming you have enough to cover either period.
What must your savings cover—and when?
Compare the same items
Spending to support
Before the future benefit begins
Living costs and planned commitments during the earlier period.
After the benefit begins
Updated living costs and commitments during the later period.
Compare the same items
Confirmed income available
Before the future benefit begins
Only income that has already begun.
After the benefit begins
Continuing income plus the benefit that now begins.
Compare the same items
Spending that savings withdrawals need to cover
Before the future benefit begins
Spending not met by the income available then.
After the benefit begins
Spending not met by the income available during that later period.
This comparison doesn’t tell you how much you should withdraw. Include taxes and changing expenses when you compare your own resources and spending.
The later benefit may reduce what savings must cover if other circumstances remain the same. Rising expenses or a changed commitment could offset that help. The comparison needs dates and assumptions, not just a list of sources.
Taxes also affect how much of a payment you can spend. Qualified-plan pension payments may be fully or partly taxable, depending on the circumstances. [4] Your tax professional should confirm how your payments would be taxed so you compare income and spending on a consistent basis.
Dovetail Principle: Financial Decisions Need to Fit Together
A future benefit and a savings account can support different parts of the same retirement. Connecting their timing to your spending shows what each must do. That relationship tells you more than either number viewed alone.
What would make the fuller picture useful?
Ask your advisor to explain which resources support your proposed retirement date, when you’d need the most from savings, and what remains uncertain. CFP Board’s planning standards require relevant personal and financial information and reasonable assumptions. [5] You shouldn’t have to piece together that reasoning from your account statements.
Then test what could change. A longer retirement, inflation, health needs, or different investment results can affect the resources required; these are among the risks discussed by the Society of Actuaries. [6] Looking at these resources and risks helps you assess the financial support for retirement. It doesn’t remove uncertainty.
You may discover that retirement deserves a closer look even though one account hasn’t reached the milestone you had in mind. Or you may find that your resources look promising over the long term while the period before a benefit begins needs more attention. Consider whether your resources can support the life you want throughout retirement. Your 401(k) is part of that answer, not the whole answer.
