You’ll have as much at retirement as your current savings, future contributions, and investment growth add up to—so the answer depends on your numbers, but there are strong rules of thumb that can get you very close.

Key rules of thumb

  • Many planners suggest you’ll want about 70%–80% of your pre‑retirement income each year to maintain a similar lifestyle in retirement.
  • One common benchmark is to save around 10× your annual income by about age 67 if you want to roughly keep your current lifestyle.
  • Another guide is the 10%–15% (or even 15%–20%) of gross income saved for retirement each year, including employer matches.

Simple “what will I have?” framework

To estimate “how much will I have at retirement,” you typically combine:

  • What you’ve already saved (401(k), IRA, pension, brokerage).
  • How much you will contribute each year until retirement (including employer match).
  • An assumed average annual return (often 4%–7% before inflation for long‑term stock‑heavy portfolios, but you choose based on risk comfort).
  • Expected retirement age and life expectancy (so you don’t outlive your savings; many calculators model income to around age 90+).

Most online retirement calculators will show both:

  • Projected value at retirement (your “what you’ll have” number).
  • Estimated yearly or monthly income that pot could provide, often using variants of the 4% withdrawal rule (spend about 4% of your nest egg per year, adjusted for inflation).

Quick mental estimate example

Here is a rough way people often sanity‑check:

  1. Estimate desired annual retirement spending (for example, 75% of your current income).
  1. Multiply that spending by about 25 (which mirrors the 4% rule) to get an approximate target nest egg.
  1. Compare that target to how much you might accumulate by saving 10%–20% of income with a moderate growth rate until your retirement age.

If your projected savings fall short of that target, you might need to:

  • Save more each year.
  • Retire later.
  • Plan on spending less in retirement or using more guaranteed income (like annuities or pensions).

Why online tools help

Because your exact answer depends on many personal inputs—age, income path, existing savings, investment returns, state or social pension entitlements—it is usually best to plug your numbers into a dedicated retirement calculator. These tools let you adjust:

  • Contribution rates.
  • Retirement age.
  • Market return assumptions (average vs poor scenarios).

All of that gives you a more precise “how much will I have at retirement?” figure tailored to your situation, plus how changing one knob (like saving a little more each month) changes the final number.
