When Can I Retire Calculator

Q: Why is the age at the top different from my target retirement age?

They answer two different questions. Target retirement age is the age you picked. The big age at the top is the earliest age your money is actually ready . The calculator checks your balance month by month. The first month your savings cover the nest egg you need, that is your answer. It can be earlier or later than your target.

Q: Why does my healthcare amount not change my goal?

It depends on which spending option you pick. Percent of current income – that percent is treated as your full budget, health costs included, so healthcare is not added twice. Custom monthly amount – healthcare is added on top of the number you type. Use the custom option if you want to see the health cost as a separate line.

Q: Why is my employer match smaller than the percent I entered?

The match is the lowest of three things: the match percent you entered, the match cap, and how much of your pay you actually put in. If your job matches 3% but you only save 2% of your pay, you get 2%. Save at least up to the cap to grab the full match. It is free money.

Q: What does Show All Figures In change?

Only the display, not the math. Today's $ shows buying power in money you understand right now. Future $ shows the bigger number that will appear on your statement later. Both are right. Today's dollars are better for judging if a number feels big enough.

When Can I Retire Calculator

Updated Jul 31, 2026 By Jehan Wadia

Introduction

The When Can I Retire Calculator shows you the age you can stop working. You type in your age, your savings, and how much you put away each month. The tool does the math and gives you an answer right away.

It looks at both sides of your plan. First, it grows your savings until you retire, adding your monthly deposits, your employer match, and investment returns. Then it works out the nest egg you need to pay your bills from your retirement age all the way to your life expectancy. Social Security, a pension, and other income lower the amount you must save on your own.

You get a target retirement age, your savings goal, and any gap you still need to close. If you are short, the calculator tells you how much more to save each month. It also shows charts, a step-by-step solution, and a what-if tool so you can test small changes, like saving $100 more or retiring two years later.

All numbers can be shown in today's dollars or future dollars, so you can see how inflation changes what your money will buy. Nothing leaves your browser, and you can print a summary when you are done. If you want a broader view of your plan, pair this with our Retirement Calculator or the How Much Do I Need To Retire Calculator.

How to use our When Can I Retire Calculator

Fill in your age, your savings, what you earn, what you save each month, and what you plan to spend in retirement. The calculator then shows the earliest age you can retire, the nest egg you need, your savings gap or surplus, and how long your money will last.

Current Age: Enter how old you are today. This sets how many years your money can grow. Not sure of your exact age in years and months? Check the Age Calculator.

Target Retirement Age: Enter the age you want to stop working. It must be higher than your current age.

Life Expectancy: Enter the age your money must last until. Most people use 90. The Life Expectancy Calculator can help you pick a number that fits your health and family history.

Filing Status: Pick Single or Married Filing Jointly. This is used to check your yearly contribution limit.

Current Retirement Savings: Add up all your 401(k), IRA, and retirement brokerage balances and enter the total. Our Net Worth Calculator is a quick way to total everything up.

Current Annual Income (Gross): Enter your pay before taxes. This sets your employer match and your spending goal. If you are paid hourly, convert it first with the Hourly to Salary Calculator.

Current Monthly Expenses: Enter what you spend in a normal month now. It is compared to your retirement spending goal. The Monthly Budget Calculator helps you nail this number down.

Monthly Contribution: Enter how much you put in each month. Count only your own money, not the employer match. To model one account on its own, try the 401k Calculator, the Roth IRA Calculator, or the IRA Calculator.

Annual Contribution Increase: Enter the percent you will raise your savings each year. Use 0 if you keep it flat.

Employer Match: Enter the percent of your pay your job adds to your plan.

Employer Match Cap: Enter the top percent of pay your job will match.

Return Before Retirement: Enter the yearly growth rate you expect while you are still working. Many people use 6% to 8%. See how that compounds with the Compound Interest Calculator.

Return After Retirement: Enter the yearly growth rate after you retire. This is often lower, like 4% to 5%.

Annual Inflation Rate: Enter how fast you think prices will rise. 3% is a common guess. The Inflation Calculator shows what past dollars are worth today.

Show All Figures In: Choose Today's $ to see buying power now, or Future $ to see real dollar amounts later.

Monthly Social Security: Enter your expected benefit in today's dollars. Turn the switch off to leave it out. Estimate your benefit with the Social Security Calculator.

SS Benefit Start Age: Enter the age your Social Security checks start, from 62 to 70. The Social Security Break-Even Calculator compares claiming early against waiting.

Monthly Pension Income: Enter any pension you will get each month. Enter 0 if you have none. Use the Pension Calculator if you need an estimate.

Other Monthly Income: Enter rent, annuity, or part-time work income you expect each month. The Rental Income Calculator and Annuity Payout Calculator can fill in those figures.

Retirement Income Goal: Pick a percent of your income now (80% is common), or choose a custom monthly dollar amount.

Include Healthcare Cost Estimate: Leave this on to add health costs, then enter your monthly healthcare amount for retirement. An HSA Calculator is useful if you save for medical costs in a tax-free account.

What-If Sliders: Move the sliders to retire sooner or later, save more, change your return, or cut spending. Your main plan stays the same so you can compare side by side.

When Can I Retire?

Retirement happens when your savings can pay your bills without a paycheck. The date is not really about your age — it is about money. Once your nest egg is big enough to cover your spending for the rest of your life, you can stop working. That is why two people the same age can have very different retirement dates.

What Decides Your Retirement Date

How much you have saved now. Money already invested has the most time to grow.
How much you add each month. Your own savings plus any employer match.
Your investment return. Higher growth means you need to save less, but it also adds risk. The Investment Calculator shows how the rate changes your ending balance.
How much you will spend. Lower spending shrinks the nest egg you need, often more than saving extra does.
Other income. Social Security, a pension, rent, or part-time work all cut how much your portfolio must cover.
How long you live. A longer life means more years of withdrawals to fund.

How Big a Nest Egg Do You Need?

A common shortcut is the Rule of 25: take the yearly amount you want to spend and multiply it by 25. Spending $50,000 a year means a $1.25 million goal. This comes from the 4% rule, the idea that you can pull about 4% of your savings in year one, then raise it a little each year for inflation, and still have money left after 30 years. You can test that rule on its own with the 4% Rule Calculator. These rules are rough. A more exact way is to find the present value of every future withdrawal, using a return that has inflation taken out — the same math behind our Present Value Calculator.

Why Inflation Matters So Much

Prices go up over time. At 3% inflation, something that costs $4,000 a month today costs about $9,700 a month in 30 years. Your savings goal must grow the same way. "Today's dollars" shows what your money can actually buy. "Future dollars" shows the bigger number you will really see on your statement — the Future Value Calculator works the same way. Both are correct — they just answer different questions.

Key Ages to Know

50 — you can add catch-up money to your 401(k) and IRA.
59½ — you can take money from retirement accounts with no 10% early penalty. Before that, see the 401k Early Withdrawal Calculator.
62 — the earliest you can claim Social Security, but checks are smaller for life.
65 — Medicare starts. Retiring before this means paying for your own health coverage.
67 — full retirement age for most workers today. The Social Security Retirement Calculator shows your benefit at each claiming age.
70 — waiting until 70 gives you the largest Social Security check.
73 — required minimum distributions begin; plan ahead with the RMD Calculator.

Retiring Before Social Security Starts

If you stop working at 60 but claim Social Security at 67, your savings must cover those seven years alone. That gap is the hardest part of early retirement, and it makes your nest egg goal noticeably bigger. Health insurance costs during those years add to the bill. If leaving work early is your goal, run the numbers again in the Early Retirement Calculator, the FIRE Calculator, or the Coast FIRE Calculator.

Ways to Retire Sooner

Four levers move your date: save more each month, spend less in retirement, work a couple more years, or earn a better return. Spending less is powerful because it does double duty — you save more now and need a smaller nest egg later. Clearing high-interest balances frees up cash fast, so check the Debt Payoff Calculator if you carry any. Always grab your full employer match first; it is free money and the fastest boost to your balance. Also plan for a bad market. If returns come in 2 points lower than you hoped, a plan with no cushion can fall apart. Once you are retired, the Retirement Withdrawal Calculator and the How Long Will My Money Last Calculator help you set a safe pace for spending.

These numbers are estimates, not promises. Real returns bounce around, taxes and health costs vary, and no plan survives untouched. Review yours once a year, and talk with a financial advisor before making big moves.

Formulas used

Monthly balance accumulation with contributions and employer match

B_{m+1} = B_m \left(1 + \frac{r_{pre}}{12}\right) + C \left(1 + g\right)^{\lfloor m/12 \rfloor} + \frac{S \left(1 + i\right)^{\lfloor m/12 \rfloor} \cdot \min\left(p_{match},\, p_{cap},\, \frac{12 C (1+g)^{\lfloor m/12 \rfloor}}{S(1+i)^{\lfloor m/12 \rfloor}}\right)}{12}

Real (inflation-adjusted) post-retirement return

r_{real} = \frac{1 + r_{post}}{1 + i} - 1, \qquad i_{mo} = \frac{r_{real}}{12}

Nest egg goal in today's dollars (present value of net monthly withdrawals)

G_{today} = W_{net} \cdot \frac{1 - (1 + i_{mo})^{-N_{ret}}}{i_{mo}}

Nest egg goal with delayed Social Security (two-phase annuity)

G_{today} = W_{noSS} \cdot \frac{1 - (1+i_{mo})^{-n_d}}{i_{mo}} + W_{net} \cdot \frac{1 - (1+i_{mo})^{-(N_{ret}-n_d)}}{i_{mo}} \cdot (1+i_{mo})^{-n_d}

Nest egg goal in future (nominal) dollars

G_{nom} = G_{today} \cdot (1 + i)^{\,A_{ret} - A_{cur}}

Savings gap and funded ratio

\text{Gap} = G_{nom} - B_{ret}, \qquad \text{Funded} = \frac{B_{ret}}{G_{nom}} \times 100\%

Extra monthly saving required to close the gap

X = \frac{\text{Gap}}{\dfrac{\left(1 + \frac{r_{pre}}{12}\right)^{N} - 1}{\frac{r_{pre}}{12}}}

Sustainable monthly withdrawal from projected savings (today's dollars)

W_{today} = \frac{B_{ret}}{(1+i)^{\,A_{ret}-A_{cur}}} \cdot \frac{i_{mo}}{1 - (1 + i_{mo})^{-N_{ret}}}

Frequently asked questions

Why is the age at the top different from my target retirement age?

They answer two different questions.

Target retirement age is the age you picked.
The big age at the top is the earliest age your money is actually ready.

The calculator checks your balance month by month. The first month your savings cover the nest egg you need, that is your answer. It can be earlier or later than your target.

What does the funded percent in the green, yellow, or red badge mean?

It compares your projected balance to your goal at your target age.

100% or more – green, On Track.
90% to 99% – yellow, Almost There.
Under 90% – red, Action Needed.

So 80% funded means you are on pace to have 80 cents for every dollar you need.

How is the Confidence Level worked out?

It is a stress test. The tool runs your plan again with returns cut by 2 percentage points, before and after retirement.

High – you still hit your goal with the lower returns.
Moderate – you hit your goal now, but a weak market breaks it.
Low – you miss the goal even in the base plan.

Markets are bumpy, so a High rating means your plan has a cushion.

Does this calculator take out taxes?

No. All amounts are before tax. Money pulled from a traditional 401(k) or IRA is usually taxed as income, and part of your Social Security can be taxed too.

A simple fix: raise your monthly spending goal by the tax rate you expect, or lower your Social Security estimate a bit.

Why does my healthcare amount not change my goal?

It depends on which spending option you pick.

Percent of current income – that percent is treated as your full budget, health costs included, so healthcare is not added twice.
Custom monthly amount – healthcare is added on top of the number you type.

Use the custom option if you want to see the health cost as a separate line.

Why is my employer match smaller than the percent I entered?

The match is the lowest of three things:

the match percent you entered,
the match cap, and
how much of your pay you actually put in.

If your job matches 3% but you only save 2% of your pay, you get 2%. Save at least up to the cap to grab the full match. It is free money.

What is the yellow warning about the IRS limit?

It shows when your yearly contribution goes over the 2026 employee 401(k) limit of $24,500, or $32,500 if you are 50 or older with catch-up.

You can still save the extra money — just put it somewhere else, like a Roth IRA or a regular brokerage account. The warning is a heads-up, not an error.

Why does my money run out before my life expectancy even though I met my goal?

The "Money Lasts Until Age" box uses your real timeline, month by month. Two things often cause an early end date:

You retire before your Social Security start age, so savings carry the whole load for a few years.
Your spending rises with inflation faster than your after-retirement return.

Try a later Social Security-friendly retirement age, a smaller spending goal, or more savings.

What does Show All Figures In change?

Only the display, not the math.

Today's $ shows buying power in money you understand right now.
Future $ shows the bigger number that will appear on your statement later.

Both are right. Today's dollars are better for judging if a number feels big enough.

What is a real return and why does the tool use it?

A real return is your growth after inflation is removed. The formula is:

(1 + return) ÷ (1 + inflation) − 1

A 5% return with 3% inflation is about a 1.94% real return. Using it lets the calculator work in today's dollars, so your goal reflects true buying power.

Why are the Rule of 25 and 4% Rule numbers different from my goal?

They measure different things.

Rule of 25 uses your whole spending budget, with no credit for Social Security or a pension.
4% Rule uses only what your portfolio must cover, and assumes a 30-year retirement.
This calculator uses your exact number of retirement years and your own real return.

The table is a sanity check, not a conflict.

What does Save This Much More Monthly mean?

It is the extra flat amount to add every month, on top of what you already save, to close your gap by your target retirement age.

It does not grow with your yearly raise, so it is a steady, easy number to set up as an auto-transfer.

Is my information saved or sent anywhere?

No. All math runs inside your browser. Nothing is uploaded, stored, or shared. Close the page and the numbers are gone.

Use the Print Summary button if you want a copy to keep.

Can my spouse and I use this together?

Yes. Add both incomes, both balances, both monthly contributions, and both Social Security checks. Then use one household spending goal.

Set Filing Status to Married Filing Jointly. Keep in mind each spouse has their own 401(k) limit, so the limit warning may show even when you are fine.

What if I get no Social Security or no pension?

Turn off the Include Social Security switch, or enter $0. Do the same for pension and other income.

Your nest egg goal will jump, because your savings now have to pay every bill on their own.

What return rate should I pick?

Common choices:

Before retirement: 6% to 8% for a stock-heavy mix.
After retirement: 4% to 5%, since most people shift to safer holdings.
Inflation: 3%.

If you are unsure, pick the lower end. A plan that works with modest returns is a plan you can trust.

Does Social Security in this tool keep up with inflation?

Yes. Enter your benefit in today's dollars and the calculator grows it with inflation, the same way real cost-of-living raises work.

That is why the amount you type stays steady in the "Today's $" view.

How does the Annual Contribution Increase help?

It bumps your monthly savings by that percent every year, like matching your pay raises.

Even a 2% yearly bump adds up a lot over 30 years, because each extra dollar has decades to compound. Set it to 0 if you plan to save the same amount forever.

Why does retiring two years later help so much?

It works on both sides at once. You add two more years of contributions and growth, and you remove two years of withdrawals.

Try it with the What-If slider. Many people find one or two extra years fixes a gap faster than a big spending cut.

Do the What-If sliders change my main plan?

No. They only fill the comparison table. Your main inputs and results stay exactly as you set them, so you can test ideas side by side without losing your plan.

Why does the tool say I cannot retire by my life expectancy?

Your savings never reach the required nest egg in the years modeled. Usual causes are a high spending goal, low savings, or a low return.

Fix it by raising your monthly contribution, lowering your spending goal, delaying Social Security, or adding other income.

How often should I redo this?

Once a year, and any time something big changes — a new job, a raise, a move, a market drop, or a new spending plan.

Retirement math shifts as your life shifts, so a yearly check keeps your date honest.
