There is no single savings target that fits every household. Estimate yours by choosing a retirement age and spending level, subtracting dependable income such as Social Security and a pension, then testing whether current savings and future contributions can cover the remaining gap across several return, inflation, tax, fee, and longevity scenarios. The guide below is U.S.-focused; the numbers and tools cited are from U.S. federal agencies.
Start with the annual amount your savings may need to provide
Build the estimate from household cash flow, not a universal income multiple. First choose a retirement age and estimate annual retirement spending. Then subtract dependable income expected in retirement. The remaining amount is an approximate annual gap that savings and investments may need to cover.
Keep the estimate internally consistent: decide whether spending is before or after taxes, and whether every amount is in today’s dollars or future dollars. Separate essential costs from discretionary spending if that helps you see which expenses may be adjustable. Housing, debt, health costs, taxes, and changes in household size can all affect spending, so use estimates that reflect your circumstances rather than assuming retirement costs will automatically fall.
Use personalized Social Security estimates
Get a benefit estimate using your earnings record through the Social Security Administration’s benefits estimate. The estimate reflects covered earnings and expected future income, but it does not include pensions or investments. Model more than one claiming age instead of treating one projected benefit as certain. The SSA online calculator lets users compare benefit estimates under different ages and earnings assumptions.

#1 Best Overall
Pay attention to the dollar basis of the estimate. The SSA calculator can show today’s dollars or future, inflation-adjusted dollars, and cautions that an inflated future benefit should not be used directly to determine other income needs. Compare like with like: a future-dollar benefit against future-dollar spending, or a today’s-dollar benefit against spending in today’s dollars.
List other dependable income separately
Record pension income and any other relatively predictable retirement income as separate entries. Do not assume an SSA estimate accounts for them; the agency says its estimate does not count pensions or investments. Once spending and income are expressed on the same tax and dollar basis, subtract the income total from spending to get the approximate annual gap.

Turn the gap into a savings projection
The annual gap is not itself a final nest-egg target. The amount needed depends on how long retirement lasts, how savings are invested and drawn down, and how inflation, taxes, and fees affect both the balance and withdrawals. Start with current retirement balances and planned future contributions, then project them under a small set of explicit assumptions. Use low, middle, and high cases rather than presenting one forecast as a promise.
- State the retirement age and the assumed retirement horizon.
- Show whether returns are stated before or after investment fees, and how inflation is treated.
- Make the tax treatment of both spending and income clear.
- Identify which inputs came from the household and which came from a calculator.
- Test more than one Social Security claiming age and more than one longevity assumption.
The IRS Saving for retirement resource points readers to plan information, fees and distributions, Department of Labor lifetime-income calculator resources, and retirement-planning toolkit materials. These can help organize an estimate, but they do not remove uncertainty from its assumptions.
Test how long savings may need to last
A retirement estimate should be tested against several possible time horizons. The SSA offers a life expectancy calculator and reports population averages for people reaching age 65 on April 1, 2026: 84.2 years for men and 86.8 years for women. Those figures describe population averages, not an individual’s predicted lifespan or a recommended planning endpoint. Use them as context, and test a longer horizon as well as a shorter one.
Longevity, investment results, inflation, and spending can interact: a longer retirement means more years of withdrawals, while actual returns and expenses may differ from the assumptions used in a projection. A range of scenarios makes those sensitivities visible without implying that any one outcome is guaranteed.

Distinguish a savings target from annual contribution limits
Contribution limits affect how quickly someone can save through tax-advantaged accounts; they do not tell a household how much it needs at retirement. For tax year 2026, the IRS announced a $24,500 elective deferral limit for most 401(k), 403(b), governmental 457 plans, and the federal Thrift Savings Plan, and a $7,500 annual IRA contribution limit. Plan terms, eligibility, and catch-up rules can change what applies to an individual. Check the IRS’s 2026 limit announcement and applicable plan rules; contribution limits can change each tax year.

If two calculators or advisers produce different targets, compare the inputs before comparing the headline numbers. A target without its assumptions is not a useful comparison.
