It is difficult to know whether you are saving enough for retirement by looking at your account balance alone. A $500,000 portfolio could be more than enough for one household and far too little for another.
The useful question is:
*Are your current savings and future contributions on a path to cover the part of retirement spending that Social Security, pensions and other reliable income will not cover?*
You can make a practical first estimate in five steps:
- Add the retirement savings you already have.
- Estimate how much you will continue contributing.
- Choose the number of years until retirement.
- Estimate annual retirement spending and reliable income.
- Compare your projected savings with a rough portfolio target.
This will not produce a guarantee. It gives you a checkpoint—a clear way to see whether your current direction looks reasonable and which part of the plan needs more attention.
Step 1: Add the savings you expect to use for retirement
Start with accounts and investments you expect to use for retirement, including:
- 401(k), 403(b), 457 and similar workplace plans
- Traditional and Roth IRAs
- (Simplified Employee Pension Individual Retirement Account) IRAs, SIMPLE IRAs and other self-employed retirement accounts
- Taxable investment accounts intended for retirement
- Cash specifically reserved for long-term retirement spending
Do not automatically include your home value. Home equity can support retirement if you plan to sell, downsize, relocate or borrow against it, but it does not pay ordinary expenses while it remains tied up in the house.
Use either today’s dollars throughout the estimate or future inflated dollars throughout it. Mixing today’s spending with future account values can make a plan appear stronger than it is.
Step 2: Count what you are still adding
Include your contributions and any employer match. If you contribute monthly, multiply the contribution by 12. If the amount changes during the year, use a reasonable annual estimate.
For 2026, the IRS says the basic employee contribution limit for many 401(k), 403(b) and governmental 457 plans is $24,500. The general age-50 catch-up limit is $8,000, and a higher $11,250 catch-up applies to eligible participants ages 60 through 63. The combined annual limit for traditional and Roth IRA contributions is $7,500, or $8,600 at age 50 or older, subject to compensation and other eligibility rules.
These limits are ceilings, not savings recommendations. The right contribution for you depends on the gap between your projected savings and what your retirement may require.
Step 3: Estimate how your savings could grow
A projection needs three inputs:
- Current retirement savings
- Future contributions
- An estimated rate of return over the years remaining
The return is an assumption, not a promise. Use more than one estimate. A lower-return case shows how the plan may behave if results are disappointing. A higher-return case can show the range without becoming the only plan you rely on.
It is often easier to plan in today’s dollars by using a *real return*, which means the estimated investment return after inflation. For example, a 4% real return represents growth in purchasing power rather than the future number printed on an account statement.
The SEC’s Investor.gov compound-interest calculator illustrates the same basic relationship: starting money, continuing contributions, time and an estimated return all affect the ending value.
Step 4: Find the amount your portfolio may need to provide each year
Your investment portfolio usually does not need to replace every dollar you plan to spend. Social Security, pensions and other reliable income may cover part of the budget.
Use this calculation:
*Annual retirement spending − annual reliable income = annual amount needed from savings*
Suppose you expect:
- $70,000 of annual retirement spending
- $35,000 from Social Security and a pension
Your savings would need to provide approximately:
*$70,000 − $35,000 = $35,000 per year*
Use Social Security estimates from your own earnings record. A personal my Social Security account can show estimated benefits at different claiming ages and lets you adjust expected future earnings.
Be careful with start dates. If you retire at 62 but plan to claim Social Security at 67, the benefit does not cover spending during those first five years. That period needs a separate source of money.
Step 5: Turn the spending gap into a rough portfolio target
A rough portfolio target estimates how much savings might be needed when retirement begins to support the annual amount your investments must provide.
One common checkpoint divides the annual portfolio spending need by an assumed starting withdrawal rate:
*Annual amount needed from savings ÷ starting withdrawal rate = rough portfolio target*
Using the previous example and a 4% starting withdrawal-rate assumption:
*$35,000 ÷ 4% = $875,000*
What the $875,000 means
It means that a $875,000 portfolio would produce a first-year withdrawal of $35,000 when multiplied by 4%.
It does *not* mean:
- You are guaranteed to have enough for life.
- You should withdraw exactly 4% every year regardless of circumstances.
- Taxes and investment fees are already covered.
- Healthcare, long-term care or major home expenses cannot change the result.
- Every dollar must be in one type of account.
The rough target is a planning checkpoint. A complete retirement analysis also needs to consider retirement length, investment mix, inflation, taxes, benefit timing, account types, large expenses and poor market returns near the beginning of retirement.
A complete example
Consider someone who is 57 and hopes to retire at 65:
| Input | Amount |
|---|---|
| Current retirement savings | $250,000 |
| Annual contributions, including employer match | $18,000 |
| Years until retirement | 8 |
| Assumed real annual growth | 4% |
| Desired annual retirement spending | $70,000 |
| Expected Social Security and pension income | $35,000 |
| Starting withdrawal-rate assumption | 4% |
Using annual compounding for a simple illustration, the current savings and contributions could grow to approximately $508,000 in today’s dollars by age 65.
The spending gap is $35,000 per year, producing a rough portfolio target of $875,000. Under those assumptions, the projection is about $367,000 below the checkpoint.
That result does not say the person has failed or cannot retire. It says the current version of the plan needs another pass.
The next questions are:
- Can contributions increase?
- Is the $70,000 spending estimate accurate?
- Does the $35,000 income estimate begin on the retirement date?
- Would working longer materially improve the projection?
- Could part-time income cover some early retirement spending?
- Is the 4% withdrawal assumption appropriate for the plan being tested?
What to do if the projection is below the target
1. Check the inputs before changing your life
A rough estimate can be wrong because an input is incomplete. Review account balances, employer match, pension estimates, Social Security amounts and the dates each income source begins.
Then build a retirement budget that includes housing, taxes, healthcare, travel, vehicle replacement, home repairs and irregular expenses. The U.S. Department of Labor’s retirement-planning guide recommends turning monthly income and expenses into an annual cash-flow plan and including employer contributions in total retirement savings.
2. Increase contributions by a specific amount
“Save more” is not an action plan. Test an additional amount per paycheck or per month and see how much it changes the projected value.
Start by capturing the full employer match if one is available. Then compare workplace-plan and IRA contribution options with the current IRS limits and your eligibility.
3. Test a later retirement date
Working longer can help in several ways at once:
- It adds more contributions.
- Existing savings have more time to grow.
- The portfolio may need to fund fewer retirement years.
- Employer health coverage may continue longer.
- Social Security estimates may change with additional earnings or a later claiming date.
Even one or two years can change several parts of the calculation, so test the actual dates instead of treating “work longer” as a vague fallback.
4. Separate essential spending from flexible spending
Do not force an unrealistic retirement budget simply to make the number work. Instead, identify:
- Essential spending that must be funded
- Flexible spending you value but could adjust temporarily
- Large one-time expenses that require separate savings
This makes it possible to build a plan for normal years and a response for difficult markets.
5. Review Social Security timing separately
Retirement age and Social Security claiming age do not have to be the same. Compare the personalized monthly amounts in your Social Security account and identify what would pay the bills while you wait.
A larger future benefit may reduce the amount the portfolio must provide later, but waiting can increase withdrawals in the early years. Both sides belong in the plan.
6. Avoid trying to solve the gap with an unrealistic return
Increasing the assumed return can make a calculator result look better without improving your actual plan. A higher expected return usually comes with greater uncertainty and investment risk.
Test a range of returns. If the plan works only under the most optimistic case, the gap has not been resolved.
What if the projection is above the target?
Being above a rough target is encouraging, but it is not the end of planning. Confirm that:
- Spending includes taxes and healthcare.
- Social Security and pension amounts begin when assumed.
- The plan has enough accessible money for the first retirement years.
- Large expenses are included.
- A market decline near retirement does not immediately force spending cuts or investment sales.
- The withdrawal rate fits the expected retirement length and investment plan.
You may also have choices that a single target cannot answer, such as retiring earlier, spending more, giving more, leaving an inheritance or taking less investment risk.

Check your current path
Use the RetireNerd Savings Checkpoint to compare projected savings with the amount your planned spending gap may require.
If the checkpoint reveals a gap, change one input at a time. Test a higher contribution, a different retirement date, a revised spending estimate or a different Social Security start date. That shows which decisions have the greatest effect.
