Retirement Calculator
This retirement calculator answers one question: will you have enough money to retire comfortably? Enter your age, savings, and monthly contribution to see how your fund grows, how much you can draw each month, and whether your money will last.
It models both halves of the journey — the accumulation phase while you save and invest, and the withdrawal phase while you draw an income — and adjusts every amount for inflation. It is built for anyone planning ahead, from a first-job saver to someone a few years from retiring who wants to know if they are on track.
How to Use the Retirement Calculator
Enter your personal info
Set your Current Age, Retirement Age, and Life Expectancy. These define how long you save and how long you draw down. Drag the sliders for quick changes or type exact ages.
Add your financial details
Fill in Current Savings, Monthly Contribution, Desired Monthly Income in today's money, and any Other Retirement Income such as a pension or social security.
Adjust the rates
Set your Expected Annual Return (7% is a common long-run stock average), the Inflation Rate (typically 2–3%), and an Annual Contribution Increase to mirror future raises.
Review your results
See your projected Retirement Fund, Monthly Income Gap, the age your fund lasts until, and an On Track or Shortfall status. The chart maps both phases, and the year-by-year table shows the full detail.
Experiment with scenarios
Change any input and watch the outcome update instantly. Try saving an extra amount each month or retiring a couple of years later to see how it closes a shortfall.
Features
Dual-Phase Projection
Models both the accumulation phase while you save and the withdrawal phase while you spend, with a chart that shows growth then drawdown.
Inflation-Adjusted Income
Your desired monthly income is converted to its future value at retirement, and withdrawals keep rising with inflation each year.
Annual Contribution Increase
Set a yearly percentage bump so your savings grow alongside future salary raises rather than staying flat.
On Track / Shortfall Status
A green On Track badge means your fund lasts your full lifespan; a red Shortfall badge warns that the plan needs adjusting.
Year-by-Year Breakdown
Expand a collapsible table of contributions, returns, withdrawals, and balance for every year, with headers splitting the two phases.
Four Summary Cards
Retirement Fund, Monthly Income Gap, Fund Lasts Until Age, and Status are surfaced at a glance above the chart.
Sliders and Live Sync
Every field pairs a slider with a typed input, and results recalculate in real time as you drag or type.
40 Currencies
A built-in currency picker covers 40 currencies, and default values and slider ranges adjust to whichever one you choose.
Frequently Asked Questions
How much money do I need to retire?
It depends on the monthly income you want and how long you expect to live in retirement. Enter your desired monthly income, life expectancy, and any other income, and the calculator projects whether your fund covers that gap for the full span. If it shows a Shortfall, your target nest egg is higher than your current plan delivers.
How much should I save for retirement each month?
There is no single number — it hinges on your age, current savings, return rate, and target income. The fastest way to find yours is to adjust the Monthly Contribution slider until the status flips from Shortfall to On Track. That contribution is the monthly amount your plan needs.
What annual return rate should I use?
A common benchmark is 7% for a diversified stock portfolio, with the historical average closer to 4–5% after inflation. If you are conservative or near retirement, a lower rate like 4–5% may fit better. The right figure depends on your investment mix and risk tolerance.
What does "Monthly Income Gap" mean?
It is the gap between your desired monthly income and any other retirement income, adjusted for inflation to its value at your retirement age. This is the amount your savings fund must cover each month.
How long will my retirement savings last?
The Fund Lasts Until Age card shows the age your money is projected to run out, based on your withdrawals growing with inflation. If the fund outlives your life expectancy, the calculator marks you On Track; if it runs dry sooner, you see a Shortfall.
What should I do if I see "Shortfall"?
A shortfall means the fund is projected to run out before your life expectancy. To close it you can increase your monthly contribution, delay retirement by a few years, lower your desired monthly income, raise your annual contribution increase, or aim for a higher return. Try each in turn and watch the status update.
Does this calculator account for inflation?
Yes. Your desired income is entered in today's money and grown to its future value at retirement, and your withdrawals keep rising with inflation each year. Most developed economies sit around 2–3%; adjust the Inflation Rate if your region differs.
Does it account for taxes?
No. This is a simplified projection and does not model taxes on withdrawals, capital gains, or tax-advantaged accounts. For tax-specific planning, speak with a qualified financial advisor.
Is my financial data private?
Yes. All calculations happen in your browser. No ages, savings, income, or rate figures are sent to any server or stored anywhere.
