Most retirement calculators throw twenty fields and a wall of jargon at you before you've even started. This one doesn't. It's built for beginners and late starters — people who feel behind and just want a clear, honest answer to one question: if I keep saving, will I be okay?
How to use this calculator
The quick estimate above needs just four numbers, and you probably already know all of them:
- Your current age — where you are today.
- Your retirement age — when you'd like to stop working (67 is a common target).
- Your current savings — roughly what you've already set aside across your accounts.
- Your monthly contribution — what you add each month, including any employer match.
Tap the button and you'll see an estimate of the monthly income your savings could provide in retirement. That's it — no spreadsheets, no finance degree required.
Pro Tip
Don't have exact figures? Estimate. A close guess gives you a useful direction today, and you can always come back and refine it. The point is to start, not to be perfect.
What the numbers actually mean
Behind the simple result are two well-known planning ideas, in plain English:
Your money grows while you keep adding to it
The estimate assumes your savings earn about a 7% average annual return — a common long-term assumption for a diversified mix of investments — and that you keep contributing every month until you retire. Over years, that combination of steady contributions and compounding growth is what builds a nest egg, even if you started later than you'd have liked.
The 4% rule turns savings into income
Once you retire, a widely used guideline says you can withdraw about 4% of your nest egg in your first year and adjust from there. So a $500,000 nest egg supports roughly $20,000 a year — about $1,667 a month — before Social Security or any other income. The calculator runs this math for you so you don't have to.
For Late Starters
Starting in your 40s or 50s doesn't mean you've missed your chance — it means your two biggest levers are how much you contribute and how many years you stay invested. Small, consistent increases to your monthly contribution add up faster than most people expect.
Why this is built for people who feel behind
A lot of retirement advice quietly assumes you started at 25 and never missed a year. That's not most people. If you're coming to this in your 40s, 50s, or later — after raising kids, paying down debt, changing careers, or just life — you are exactly who this tool is for. The goal here isn't to make you feel bad about the past. It's to show you, honestly, what's still possible from where you stand today, and what changing one number (saving a little more, working a couple more years) does to the picture.
The quick estimate gives you the headline. When you're ready to see the whole thing — your 401(k), IRA, HSA, and brokerage accounts, plus Social Security, any pension or rental income, and how your target retirement age changes everything — the full calculator builds your complete, personalized projection, including how much of your current income you're on track to replace.
Frequently asked questions
Is it too late to start saving for retirement in my 40s or 50s?
No. Starting later leans more on steady contributions and a few more working years than on decades of compounding, but a real retirement is still very achievable. This calculator is built for late starters — it plans from where you actually are.
How much do I need to retire?
A common rule of thumb is to replace 70–80% of your pre-retirement income. The exact dollar figure depends on your lifestyle and your other income sources. The full calculator compares your projected income to your goal and shows the gap.
What monthly income could my savings provide?
Using the 4% rule, about 4% of your nest egg per year. A $500,000 balance supports roughly $1,667/month before Social Security or other income. The calculator does this for you and adds your other sources.
What return and withdrawal rate should I assume?
It defaults to a 7% average annual return and a 4% withdrawal rate — common planning assumptions for a diversified, long-term portfolio. They're estimates, not guarantees, and you can adjust both in the full tool.
Does this include Social Security and my 401(k)?
The quick estimate keeps it simple with savings and contributions. The full calculator adds your 401(k), IRA, HSA, and brokerage, plus Social Security, pension, and rental income for a complete monthly projection.
Is my information private?
Yes. The quick estimate runs entirely in your browser — nothing is sent or stored. The full calculator asks only for your email to confirm access.
