Free Retirement Calculator

Your Retirement Projection

The results card updates as you type. It answers two separate questions, and it is worth keeping them apart.

Until you enter a return, the card shows only your contributions — the money you will actually put in, which is arithmetic and needs no assumption. Everything that depends on growth stays blank. That is deliberate: this page will not invent a market return on your behalf.

Open View Full Breakdown to separate your own contributions from investment growth, to see the balance in both future and today's money, and to find the age at which your target is first met. That last row is the honest answer to when can I retire on your current plan.

What Is a Retirement Calculator?

A retirement calculator takes what you have saved, what you keep adding and how long you have, and projects the balance forward to the age you plan to stop working. A retirement savings calculator and a nest egg calculator describe the same tool — the names differ, the arithmetic does not.

What makes it a retirement income calculator rather than just a growth projection is the second step: converting the final balance into an annual income, so you can compare it with what you expect to spend. A balance on its own is hard to judge. An income figure sits next to your current spending and means something immediately.

Three things a calculator like this genuinely does well:

• It shows the direction and scale of a change — what happens if you save $100 more, or work two years longer.
• It separates your contributions from growth, which is the clearest way to see compounding at work.
• It translates a distant, abstract balance into an income you can sanity-check against today's bills.

And one thing it cannot do: tell you what markets will return. Every projection here rests on an assumption you supply, and the further out you look, the wider the real range of outcomes becomes.

How Retirement Savings Are Projected

The projection has five inputs. Each one does a specific job, and knowing which is which makes the output far easier to read.

Current savings

Everything you already hold for retirement, across every account. This is the part that compounds for the longest, which is why a modest balance started early often outweighs a larger one started late. It grows whether or not you add another dollar.

Monthly contributions

What you add each month from here on, including any employer match you receive — a match is part of what lands in the account, so leaving it out understates your plan. Each deposit is treated as arriving at the end of its month, the standard convention for this calculation.

Assumed return

The annual growth rate you want to test, compounded monthly. This field is blank on purpose. Returns depend on what you invest in, the fees you pay and conditions nobody can forecast, so we will not fill it in for you. Run more than one figure: a cautious assumption and an optimistic one bracket the realistic range far better than a single number does.

Years to retirement

Simply your retirement age minus your current age. It is the most powerful input on the page, because growth compounds over time rather than adding up in a straight line. Pushing retirement back by a few years lengthens the growth period and shortens the period the money must cover, which moves the result from both ends at once.

Target income

The annual income, in today's money, that you want your savings to provide. This is what turns an abstract balance into a pass-or-fail answer. It is also the figure the tool searches against when it reports the age your plan first becomes sufficient.

How Much Should You Save for Retirement?

This is the question everyone arrives with, and it is the one we will not answer with a number. Not because the answer is unknowable, but because how much do I need to retire has a different answer for almost every household, and a figure pulled from an article is as likely to mislead you as help you.

What actually determines it:

• Your spending, not your income. Retirement replaces what you spend. Two people earning identically can need very different amounts if one has a paid-off home and the other pays rent.
• Where you live. Housing, state taxes and especially health costs vary enormously by location, and they are among the largest items in a retirement budget.
• How long it lasts. A retirement that runs thirty years needs materially more than one that runs fifteen, and longevity is not something you can know in advance.
• What else arrives. Social Security, a pension, rental income or part-time work all reduce what your savings must produce on their own.

So the mechanism is what matters: your savings must produce enough annual income, after inflation, to cover the gap between your spending and your other income sources. That is precisely what the calculator models — you supply the target, it tells you whether the plan reaches it.

For authoritative, non-commercial information, the IRS retirement plans pages cover account types and the contribution and distribution rules that apply to them, and the Social Security Administration explains how benefits are worked out and what claiming age does to them. Both change from year to year, so check them directly rather than relying on figures quoted elsewhere — including here.

How Your Savings Rate Changes the Outcome

Of everything on this page, the monthly contribution is the input you control most directly. The table below is built from your own figures — your current savings, your time frame, your assumed return — with only the monthly amount varied, so you can see the effect in isolation.

Two patterns are worth noticing. First, the gap between the middle column and the right-hand column is compounding — the money you never contributed. Second, that gap widens disproportionately as the contribution rises, because every extra dollar gets the full remaining time to grow.

This is also why a raise is such a useful moment. Directing part of an increase into retirement saving raises the contribution without lowering your current standard of living, and the earlier in your career it happens, the longer it compounds. Our guide to saving for retirement in your 30s works through that timing in more detail, and the compound interest calculator isolates the growth mechanism on its own.

Retirement Calculator vs 401(k) and Roth IRA Calculators

These tools overlap, and picking the wrong one wastes time. The difference is scope: this page models your retirement savings as a whole, while account-specific calculators model the rules of one particular wrapper.

In practice most people need the broad projection first and the account-specific detail second. Work out whether your overall plan reaches your target here, then look at which accounts are the most efficient place to hold the money. Contribution limits and income thresholds for each account type change annually, so take those from the IRS directly.

One boundary worth repeating: this calculator does not include Social Security. Whatever benefit you expect should be estimated separately through your SSA account and then treated as income arriving alongside what your savings produce.

How to Use This Retirement Calculator

1. Enter your current age and the age you plan to retire. The gap between them is your saving period, and it drives everything else.
2. Add your current retirement savings. Total everything already invested for retirement, across all accounts.
3. Enter your monthly contribution, including any employer match — that money lands in the account too.
4. Choose an assumed annual return. The field is blank by design. Pick a figure you are willing to defend, then try a lower one.
5. Set the inflation and withdrawal rates. Inflation converts the result into today's money; the withdrawal rate converts the balance into an annual income.
6. Enter your target annual income in today's money, then read the verdict line.

Read the projected income before the balance. A seven-figure nest egg sounds decisive, but the income it produces in today's money is the figure that tells you whether the plan works.

Then change one input at a time. Add two years to the retirement age. Raise the contribution by $100. Drop the return by a point. Watching which lever moves the verdict furthest is more useful than any single run, and it costs nothing to try. Nothing you enter is stored or sent anywhere.

Our Methodology

The balance is projected with the standard future-value formula for a lump sum plus a regular deposit, compounded monthly: FV = P(1+r)ⁿ + M × ((1+r)ⁿ − 1) ÷ r, where P is your current savings, M the monthly contribution, r your assumed annual return divided by twelve, and n the number of months. Deposits are treated as arriving at the end of each month.

That balance is then discounted by your inflation rate to express it in today's money, and multiplied by your withdrawal rate to give an annual income. The "target reached at" figure is found by stepping forward one year at a time and reporting the first year whose income meets your target; if no year within sixty does, we say so rather than display a misleading age.

Before publication the engine was verified against an independently written month-by-month simulation across eight scenarios, confirmed to reproduce published annuity values exactly, and checked at the edges — zero return, zero years, unreachable targets. All currency is rounded to cents before display, because raw floating-point arithmetic produces artefacts such as 29750.000000000004 that should never reach a reader.
