How do I calculate my retirement income needs?

Updated October 2026 · How we answer

Short answerStart by estimating your annual expenses in retirement, then subtract guaranteed income like Social Security and pensions. The gap is what you'll need to cover from savings. A common approach is to aim for 70–80% of your pre-retirement income.

Estimate your expenses

Track your current spending for a few months to get a baseline. Then adjust for changes: you may spend less on commuting and work clothes, but more on travel, hobbies, and healthcare.

Don't forget irregular expenses like car repairs, home maintenance, and gifts. A retirement budget should include an emergency fund for unexpected costs.

  • Housing: mortgage/rent, property taxes, insurance, maintenance
  • Healthcare: premiums, out-of-pocket, long-term care
  • Living: food, utilities, transportation, travel, entertainment

Subtract guaranteed income

Add up your expected Social Security, pension, and any annuity income. Social Security statements are available online at ssa.gov. For a rough estimate, the average retired worker benefit is around $1,900 per month in 2024.

The difference between your expenses and guaranteed income is the amount you need to withdraw from savings each year. Multiply that by 25 to get a rough savings target (based on the 4% rule).

  • Include part-time work income if you plan to work in retirement
  • Consider rental income or other sources

Common mistakes

  • Using your current income instead of your expected retirement expenses.
  • Forgetting to account for inflation, which reduces buying power over time.
  • Overlooking taxes on withdrawals from traditional IRAs and 401(k)s.
