Retirement Calculator

The Retirement Calculator lets you explore how current savings and regular contributions might grow by a planned retirement age. You can also enter an inflation assumption and an optional yearly retirement-income goal to view an illustrative savings target and any displayed gap or surplus.

Treat the results as scenarios, not forecasts or promises. Investment returns, inflation, fees, taxes, and your future saving habits may differ from the assumptions you enter.

What the retirement calculator shows

Enter your current age, planned retirement age, current retirement savings, monthly contribution, and estimated annual return. The calculator displays projected savings, total contributions, estimated investment growth, and the years until retirement. If you enter an inflation rate, it also displays an inflation-adjusted value.

You can optionally enter desired yearly retirement income and a withdrawal rate. With an income goal entered, the results can include a required nest egg and a gap or surplus compared with projected savings. These are estimates based on the information entered; they do not guarantee that a particular income will be available.

The tool asks for a few inputs, but the result depends on the assumptions behind them. A useful estimate is one you can explain, compare with alternatives, and revisit.

Inputs to gather before you calculate

Use current information where possible. Check account statements for your savings balance and pay records or plan documents for your actual contribution. Avoid counting the same account or employer contribution twice.

For an income goal, begin with the retirement spending you expect rather than choosing a target simply to make the calculation look comfortable. NerdWallet’s retirement-calculator guidance suggests using current spending as a starting point and considering how expenses might change in retirement. This can help frame an estimate, but your future budget may be quite different.

The annual return is an assumption, not a rate you are promised to earn. Consider testing a lower-return scenario as well as a more favorable one. If you are unsure whether the return input is nominal or inflation-adjusted, read the calculator’s labels carefully and keep your savings figure and goal on a consistent basis.

Input	What it represents
Current age and retirement age	The time remaining before your planned retirement date
Current savings	Retirement money already accumulated
Monthly contribution	The regular amount you expect to add
Expected annual return	An assumed rate used for the projection
Inflation	An optional assumption used to express a future balance in estimated purchasing-power terms
Yearly retirement-income goal	An optional target used to estimate a required nest egg and compare it with projected savings
Withdrawal rate	An optional input associated with the income-target calculation

How to use the calculator

Enter your current age and the age at which you hope to retire. Add your current retirement savings, monthly contribution, and estimated annual return, then select Calculate.

For a basic projection, leave the optional inflation and income-goal fields blank. To explore purchasing power, enter an inflation assumption. To compare projected savings with an income target, enter the yearly income amount and, if appropriate, a withdrawal-rate assumption.

Review the displayed results before changing inputs. Then adjust one assumption at a time—for example, your contribution or retirement age—to make it easier to see which change is associated with a different projection. If you change several inputs together, it is harder to tell what drove the difference.

The calculator displays a validation prompt if a required input is missing. In testing, clearing current age produced the message, “Enter your current age.” Other validation rules and edge cases were not tested.

A tested projection example

In one tested calculation, the inputs were age 35, retirement age 65, current savings of $40,000, monthly contributions of $600, and an estimated annual return of 6%. Inflation and the income goal were left blank.

The calculator displayed projected savings of $843,612.03 after 30 years. It also showed total contributions of $256,000.00, investment growth of $587,612.03, and an inflation-adjusted value of $843,612.03. The details showed 360 months and an estimated monthly return of 0.5%.

For this example, the displayed contribution total equals the $40,000 starting balance plus $600 for each of 360 months: $40,000 + ($600 × 360) = $256,000. The displayed investment-growth amount is $587,612.03. These are observations from the tested inputs, not confirmation of a general calculation method or a prediction of what any portfolio will earn.

This example shows how the calculator presents its output. It is not a recommended return assumption or a target balance for every saver.

Adding inflation to the projection

A future account balance is stated in future dollars. An inflation-adjusted value estimates what that balance might represent in purchasing power after applying the inflation assumption. It is not a second account balance, and it does not mean money has been removed from the account.

Using the same age, savings, contribution, and return inputs as the example above, a tested calculation entered 3% inflation. The calculator continued to display projected savings of $843,612.03 and showed an inflation-adjusted value of $347,556.99. In that scenario, the purchasing-power estimate differed from the nominal projection.

The inflation-adjusted figure depends on the assumption entered and the time period. It cannot tell you what prices or your personal expenses will actually be decades from now. Use it as a comparison aid, and avoid comparing a future-dollar savings target with a goal stated in today’s dollars without accounting for the difference.

Comparing savings with an income goal

An income goal can make an account-balance projection more practical by giving you a way to compare savings with the income you hope to have. In one tested scenario, the inputs included $50,000 in desired yearly retirement income and 3% inflation, while the withdrawal-rate field was left blank.

The calculator displayed a required nest egg of $1,250,000.00, projected savings of $843,612.03, and a gap of -$406,387.97. The calculation details displayed a 4% withdrawal rate even though the field had been left blank. Testing did not establish why that value appeared. Check the rate shown in your own results rather than assuming a blank field has a particular meaning.

A second tested calculation changed current savings from $40,000 to $10,000 while retaining the other inputs. It displayed projected savings of $662,934.78 and a gap of -$587,065.22. These results show how the displayed comparison changed in those scenarios; they do not establish a universal rule for how every input affects the calculator.

A required nest egg or displayed gap does not establish that the target is sufficient, that a withdrawal rate is suitable for you, or that the projected balance can safely provide the income you want. Consider the assumptions and limitations alongside the result.

Read the projection as a scenario, not a promise

A calculator can apply a steady assumption over many years, while real investment returns vary. Actual results can be higher or lower, and the order in which gains and losses occur can matter, especially after withdrawals begin. A single projected balance does not represent every possible market path or future circumstance.

The result also depends on what the calculator includes. Testing did not establish how this tool handles investment fees, taxes, contribution timing, future contribution increases, or interruptions in saving. Do not assume these factors are included unless the tool clearly asks about them or explains its method.

Edward Jones describes its own retirement calculator as illustrative and says its estimates do not account for fees or taxes and are not guaranteed investment results. This is a useful reminder to check the assumptions and limitations of whichever calculator you use; it is not confirmation of how this calculator handles those items.

If other income will affect your retirement plan, consider it separately and avoid counting the same source twice. Examples might include a pension or a government retirement benefit. Use an individual estimate from the relevant official source rather than guessing a benefit from salary alone.

Build useful comparison scenarios

One calculation can make a plan seem more certain than it is. Instead, compare a few clearly labeled scenarios. A cautious scenario might use a lower estimated return, a higher inflation assumption, or a smaller contribution if you expect saving to be difficult at times. A working scenario can use your current balance and a contribution you realistically expect to make. An optimistic scenario can test stronger returns or contributions, but label it as optimistic rather than treating it as your expected outcome.

You can also compare retirement ages. Changing the planned date changes the time period used in a projection, but the calculator cannot determine whether a specific retirement age is practical or desirable for you.

Change one input at a time and record the assumptions with each result. This makes comparisons easier to understand and helps keep a favorable estimate from quietly becoming your plan.

What the calculator cannot decide for you

The projection is not a personalized financial plan. It does not know your future spending, health needs, taxes, investment choices, account rules, or how long your retirement may last. A savings target by itself also does not establish a sustainable withdrawal strategy.

An account balance is not always the same as money available to spend. Tax treatment depends on account type, location, and the rules in effect when contributions or withdrawals occur. If taxes are not explicitly modeled, read the projection as an estimated balance rather than an after-tax spending amount.

The calculator cannot determine whether you qualify for a particular account or benefit, whether an employer contribution will vest, or what current contribution limits apply. Check current plan documents and official information for rules that affect your circumstances.

The tool is most useful for asking “What if?” questions. It is not a substitute for verifying account information or seeking qualified advice when a decision depends on your personal tax, investment, or retirement-income situation.

A simple review routine

When you save a result, note the date, current savings, contribution amount, retirement age, return assumption, inflation assumption, and any income goal or withdrawal rate. A screenshot without its assumptions may be difficult to interpret later.

Update the calculation when your account balance or contribution changes, or after a major change in your retirement timing or spending goal. Replace old estimates with actual account figures whenever they are available.

Treat the calculator as a planning aid: use reasonable inputs, compare alternatives, and revisit your assumptions. The value is not one precise-looking number, but a clearer view of how the result changes when your plan changes.

Frequently asked questions

What information do I need to use the retirement calculator?

Enter your current age, planned retirement age, current retirement savings, monthly contribution, and estimated annual return. Inflation, desired yearly retirement income, and withdrawal rate are optional inputs.

What does the inflation-adjusted value mean?

It estimates the projected balance’s purchasing power after applying the inflation assumption. It is not a separate account balance, and it depends on the rate and period used in the calculation.

Why does the calculator show a gap or surplus?

When you enter an income goal, the results can compare projected savings with a required nest egg and display the difference. The comparison depends on the assumptions shown; it does not guarantee that the target or income will be sufficient.

What happens if I leave the withdrawal-rate field blank?

In one tested income-goal scenario, the field was blank but the displayed calculation details used a 4% withdrawal rate. Testing did not establish why. Check the rate shown in your results, and do not assume a blank field means a particular value.

Does the projected balance include taxes and fees?

Testing did not establish whether this calculator models taxes or fees. Unless the tool explicitly says they are included, treat the result as an estimate before any costs or taxes that may apply.

Why should I run more than one calculation?

A projection can change when assumptions such as return, contribution, inflation, or retirement timing change. Comparing scenarios shows how sensitive the estimate is without implying that any one scenario is certain to happen.
