How Much Money Will I Need in Retirement
Our easy retirement calculator shows how investing — not just saving — can dramatically impact your future. Inflation slowly erodes savings, but investing in quality businesses and adding money over time allows your portfolio to grow and compound.
This free, educational tool helps you understand your retirement number by factoring in things like inflation, income, age, savings, and expected returns — so you can plan with confidence, not guesswork.

Finding Your Number
Estimate your retirement budget; how much do you want to spend each year?
How many working years do you have left before you plan to retire?
How long do you want your retirement to last? (Hint: Planning for a longer retirement gives you a safety net.)
Getting the actual numbers always helps. You might think that your pre-retirement income would be enough to coast through retirement. But it's best to be sure. Plug your numbers into the calculator, account for inflation, and see if you're on track to hit your retirement goals. That's the power of seeing it all laid out!
Avoiding Common Pitfalls
We've all seen those calculators that spit out a number and call it a day. But real life is messier. Here are a few things to watch for:
Understanding Your Results
- Your Number: This is your estimated retirement savings target. It's the amount you may need to support your retirement lifestyle, in today's dollars.
- Over / Under: Are you on track, or is there a gap? If you're under, it's not a failure — it's a planning signal.
- Run Out of Money / Years Without Money: If your plan comes up short, the calculator shows how long your savings might last. Use this info to adjust your plan, not to stress.
Gather Your Numbers
Jot down your current age, current retirement savings, annual income, and expected retirement age.
If you're under your target, consider:
- Increasing your annual contributions (even a little helps)
- Working a few extra years (not always fun, but sometimes necessary)
- Revisiting your assumptions, like inflation rate or investment returns
- Adjusting your retirement budget or lifestyle goals

How accurate are retirement calculators?
Retirement calculators provide estimates based on the assumptions you enter. They're great for planning and exploring scenarios, but real-world results will vary based on market conditions, inflation, and life changes. Use them as a starting point, not a guarantee.
What if inflation or returns are different than I expect?
That's exactly why it's important to run multiple scenarios. Try adjusting the inflation rate and expected returns to see how your plan holds up under different conditions. Rule #1 investors aim for 15%+ returns, which provides a significant margin of safety.
Can I include social security, pension, 401k, or other income?
This calculator focuses on your personal savings and investments. For a complete picture, subtract any expected Social Security, pension, or other income from your desired lifestyle cost before entering it.
What's the difference between saving and investing for retirement?
Saving means putting money aside, usually in low-interest accounts. Investing means putting your money to work in businesses that grow over time. Rule #1 investing focuses on buying wonderful companies at attractive prices, which can dramatically accelerate your path to retirement.
How often should I revisit my retirement accounts and plans?
At minimum, review your plan annually or whenever you experience a major life change (new job, marriage, kids, etc.). The earlier you catch a shortfall, the easier it is to adjust.
