Money you contribute
Regular contributions from your paycheck or bank account help build your retirement reserves over time.
401k Calculator & Guide
Retirement savings can help fund the life you want after work, from everyday expenses to healthcare, travel, and unexpected costs. The key is to set a realistic goal, save consistently, and understand how time, contributions, and investment returns work together.
This guide explains how to estimate your retirement savings target, build a savings habit, use retirement accounts, and explore how your money could grow over time.
Retirement savings are money and investments you set aside to help pay for living expenses when you stop working or reduce your working hours. They may be held in employer-sponsored plans, individual retirement accounts, taxable investment accounts, savings accounts, or other assets.
Regular contributions from your paycheck or bank account help build your retirement reserves over time.
Investments may earn returns, and reinvested earnings can generate additional returns. Growth is not guaranteed.
Your savings can work alongside Social Security, pensions, and other income sources to help fund retirement.
There is no single retirement savings number that works for everyone. Your target depends on your planned retirement age, expected spending, other income, health costs, housing, and how long your savings may need to last.
Begin with your current expenses, then adjust for changes you expect in retirement. Some costs may fall, while healthcare, travel, housing, or family support could rise.
Consider potential Social Security benefits, pension income, rental income, and other reliable sources. Use realistic estimates rather than assuming every source is guaranteed.
Prices can rise over decades. A retirement budget based only on today's dollars may understate future spending needs.
Market declines, longer lifespans, unexpected expenses, and changes in income can affect your plan. Revisit your target periodically.
Estimate how your current savings and future contributions could grow by your chosen retirement age. Adjust the inputs to compare scenarios.
Enter your assumptions to explore a hypothetical savings scenario.
This is a simplified projection, not a forecast or guarantee. It assumes monthly contributions and a constant effective annual return, with contributions increasing annually. Actual returns fluctuate, and the calculation excludes fees, taxes, contribution limits, employer-match details, and changes in your circumstances. The inflation-adjusted figure uses your entered inflation assumption.
Different accounts offer different tax treatments, contribution rules, investment choices, and withdrawal conditions. Your employer benefits and personal situation can influence which options are available.
| Account type | General features | What to check |
|---|---|---|
| Traditional 401(k) | Eligible employee contributions generally reduce current federal taxable income; withdrawals are generally taxable. | Employer match, vesting, investment menu, fees, and plan rules. |
| Roth 401(k) | Contributions are made after tax; qualified distributions can be tax-free under applicable rules. | Eligibility, plan features, qualified distribution rules, and employer-match treatment. |
| Traditional IRA | Contributions may be deductible depending on eligibility and circumstances; withdrawals are generally taxable to the extent they represent untaxed funds. | Deduction rules, income, workplace plan coverage, and annual limits. |
| Roth IRA | Contributions are made after tax; qualified withdrawals are tax-free. | Income eligibility, contribution limits, and withdrawal ordering rules. |
| Taxable brokerage account | Can offer flexible access without retirement-account distribution rules. | Tax on dividends, interest, and realized capital gains. |
| Health Savings Account (HSA) | Eligible individuals with qualifying coverage may receive tax advantages for qualified medical expenses. | Eligibility, qualified expense rules, and the role of healthcare costs in your plan. |

Consistency often matters more than trying to find a perfect starting amount. Build a routine you can maintain and increase savings when your finances allow.
Choose an amount that fits your budget. If you have access to a workplace plan, review how contributions are deducted from pay and how the plan handles employer matching.
Automatic payroll deductions or scheduled transfers can help make saving consistent instead of relying on what remains at the end of each month.
Consider increasing contributions when your pay rises, a debt is paid off, or your household budget improves. Review annual limits before making large changes.
Understand the available investments, your time horizon, risk tolerance, diversification, and fees. A target-date fund may be one option to research if available in your plan.
Check your allocation periodically and compare it with your intended plan. Avoid making frequent changes based only on short-term market movements.
Understand withdrawal taxes and penalties before accessing retirement funds. Review beneficiaries and keep your account information current.
Investment expense ratios and plan administrative fees reduce the amount of money that remains invested. Compare costs alongside investment objectives and risks.
A reserve for unexpected expenses may reduce the likelihood of needing to withdraw long-term retirement money at an inconvenient time.
Your priorities can change as you approach retirement. Age-based guides are useful for planning, but they are not a scorecard: savings balances vary with income, career interruptions, family responsibilities, location, and retirement goals.
Build a savings habit, understand your employer benefits, and learn the basics of investing. Time can give contributions more opportunity to compound.
Review savings rates as income and expenses change. Balance retirement goals with housing, childcare, debt, and emergency reserves.
Assess whether your savings trajectory matches your intended retirement date. Review investment allocation, fees, and contribution opportunities.
Review catch-up contribution eligibility, projected retirement income, healthcare needs, and whether your portfolio reflects your time horizon.
Focus on withdrawal planning, income sources, healthcare, required minimum distributions when applicable, and how savings may need to last.
Build a realistic spending plan, review Social Security timing, and consider how to manage withdrawals during different market conditions.
Delaying until you can save a large amount may mean missing opportunities to build a consistent habit. Start with a manageable amount and review it later.
Small annual costs can compound over time. Learn what your plan charges and compare investments with similar objectives.
Holding too much in one company or one narrow investment category can expose savings to concentrated risk.
Early distributions may trigger income taxes and an additional tax. Compare plan loans and other resources before deciding.
Markets do not deliver the same return every year. Test more than one scenario and remember that losses near retirement can have a substantial impact.
Life events, salary changes, family needs, and retirement timing can all affect your savings target. Revisit your assumptions periodically.
Common questions about saving, account choices, and retirement readiness.
The amount depends on expected retirement spending, other income, retirement age, taxes, health costs, and how long the money may need to last. Use a personalized projection rather than relying only on a generic age-based target.
Review any workplace retirement plan and employer match, set an affordable contribution, automate it, and learn the investment options and fees. Build emergency savings and account for essential expenses as part of your broader financial plan.
It may be a major part of your retirement plan, but whether it is enough depends on your balance, contribution rate, investment results, retirement expenses, and other income sources such as Social Security or a pension.
Traditional contributions generally provide a current federal income-tax benefit, while Roth contributions are made after tax and may qualify for tax-free distributions. The relative value depends on your current and future tax circumstances and the plan's rules.
There is no universal percentage. Consider your budget, employer match, contribution limits, other financial obligations, and retirement target. A sustainable contribution that you can increase over time may be more practical than an unrealistic starting amount.
Yes. Starting later still gives you options, although you may need to save more, work longer, adjust your retirement spending, or review other sources of income. Check whether age-based catch-up contributions are available to you.
Your account value may decline if your investments lose value. Diversification, an allocation suited to your time horizon, and avoiding panic-driven decisions can help you manage risk, but they cannot eliminate losses.
Account statements usually show nominal balances unless adjusted. To understand purchasing power, estimate future balances in today's dollars using an inflation assumption. Actual inflation will vary over time.
Review your contributions, investments, and goals periodically and after major life or employment changes. Avoid making frequent investment changes solely in reaction to short-term market movements.
Use official sources to verify account rules, contribution limits, and retirement planning information. Tax rules and annual limits can change.
Estimate your potential savings growth, review your workplace retirement options, and revisit your strategy as your goals and financial circumstances evolve.
