Retirement planning means estimating the money you will need after work, identifying dependable income sources, and building savings and investments to cover the difference. A practical plan also accounts for inflation, taxes, medical costs and the possibility of living longer than expected.
You do not need one universal “magic number.” Begin with your expected expenses, subtract realistic income from sources such as Social Security and pensions, then test how contributions and withdrawals could support the remaining amount. The examples below are educational models, not guaranteed investment outcomes.
Step 1: Estimate the income you will need in retirement
You may see guidance suggesting retirement income of 70% to 80% of pre-retirement pay. Treat that as a rough starting point, not a spending forecast. Your needs depend on housing, household size, debt, taxes, travel plans, healthcare and whether you will support other people.
List expected annual expenses in today’s dollars. Include housing, utilities, food, transportation, insurance, healthcare, taxes and irregular costs such as replacing a vehicle or repairing a home. Some expenses may fall when work ends; others may rise. Keep your inflation assumption visible when projecting these amounts into the future.
Work backward from the income gap—not your salary alone
Suppose a household expects to spend $60,000 per year in retirement, with an illustrative $24,000 in annual Social Security benefits and $6,000 from a pension. For this simplified first-year illustration, assume the income and spending amounts are compared on a consistent tax basis; ignore future benefit increases. In a real plan, estimate taxes on benefits and portfolio withdrawals separately.
| Item | Annual amount |
|---|---|
| Planned expenses | $60,000 |
| Less Social Security income | −$24,000 |
| Less pension income | −$6,000 |
| Amount the investment portfolio must provide | $30,000 |
If you divide the $30,000 gap by a hypothetical starting withdrawal rate of 4%, the resulting $750,000 portfolio target is a planning benchmark, not a guarantee. At a more cautious 3.5% initial rate, the corresponding target is about $857,143. Neither calculation includes an individual tax projection.
Get an estimate of your own Social Security retirement benefit from your my Social Security account. For people born in 1960 or later, full retirement age is generally 67. Benefits may start at 62 with a permanent reduction; delaying benefits after full retirement age can increase the monthly amount up to age 70. Medicare eligibility follows different age rules. The Social Security Administration explains the claiming trade-offs.
Use the site’s Retirement Calculator to explore scenarios, but confirm whether its input and output dollar values are nominal or inflation-adjusted and whether it assumes Social Security is already deducted from the spending target.
Step 2: Choose accounts that fit your tax situation
Retirement accounts generally provide either tax-deferred treatment or potential tax-free qualified withdrawals. They are account types, not investments: after opening an IRA or joining a workplace plan, you still must choose investments and monitor their costs.
Traditional 401(k) and traditional IRA
Traditional pre-tax 401(k) contributions generally reduce current taxable wages and investments grow tax-deferred; withdrawals are usually taxed as ordinary income. A traditional IRA contribution may or may not be deductible depending on income and workplace-plan coverage. Withdrawals can have additional basis-related rules.
Roth 401(k) and Roth IRA
Roth contributions use after-tax dollars. Qualified distributions can be tax-free, subject to applicable age, holding-period and other requirements. Direct Roth IRA contribution eligibility can be restricted by income; the tax treatment of Roth IRA contributions differs from the treatment of earnings and conversions.
If your employer offers a match, understand the plan formula and vesting rules. For example, a 50% match on the first $2,000 you contribute would add $1,000 of employer money if you satisfy the plan terms. This is employer compensation—not a risk-free investment return, because the invested money can still lose market value.
Choosing between traditional and Roth accounts depends on current tax rates, potential future taxes, eligibility and the flexibility you need. See Roth IRA vs. Traditional IRA for the detailed comparison.
2026 IRS retirement contribution limits
The following 2026 calendar-year amounts apply to most standard 401(k), 403(b), governmental 457(b) and IRA arrangements, subject to plan terms, compensation limits and eligibility. The workplace values are employee elective deferrals; separate employer and total-plan contribution rules may apply.
| Age at year-end | 401(k), 403(b), eligible governmental 457(b) | Traditional or Roth IRAs combined |
|---|---|---|
| Under 50 | $24,500 | $7,500 |
| 50–59 or 64+ | $32,500 (includes $8,000 catch-up) | $8,600 (includes $1,100 catch-up) |
| 60–63 | $35,750 (includes $11,250 higher catch-up) | $8,600 (includes $1,100 catch-up) |
These figures are not limits for SIMPLE plans, and special 403(b) service-based and governmental 457(b) catch-up rules may also apply. IRA contributions across traditional and Roth accounts share one combined annual limit, not one limit per account.
For 2026, the direct Roth IRA contribution income phase-out is $153,000–$168,000 for single filers and heads of household, and $242,000–$252,000 for married couples filing jointly (based on modified adjusted gross income). Other filing statuses have different rules. Traditional IRA deductibility is governed by separate income and coverage requirements. Verify your situation against the IRS 2026 contribution-limit announcement.
Step 3: Turn a monthly contribution into a retirement projection
Consider contributing $500 at the end of every month for 30 years, starting with no balance. For this illustration only, assume an unchanged 6% nominal annual rate compounded monthly, no taxes or fees and no withdrawals. A real investment portfolio does not pay a fixed monthly return.
| Years | Total contributed | Modeled growth | Projected balance |
|---|---|---|---|
| 10 | $60,000.00 | $21,939.67 | $81,939.67 |
| 20 | $120,000.00 | $111,020.45 | $231,020.45 |
| 30 | $180,000.00 | $322,257.52 | $502,257.52 |
The $180,000 in contributions is money you supply; the additional $322,257.52 depends entirely on the model’s rate assumption. Market returns vary and losses are possible. A 6% effective annual return would use a different monthly conversion than the 6% nominal annual rate specified above.
These figures are future nominal dollars. For example, at an assumed average 2.5% inflation rate, the $502,257.52 ending amount would have the purchasing power of approximately $239,447.60 in today’s dollars after 30 years, calculated as $502,257.52 ÷ (1.025)30. Fees and taxes could reduce the amount further. For the mechanics of deposit timing, see the Future Value guide.
Choose an investment mix and monitor costs
A retirement portfolio often contains diversified stock and bond investments, with liquid cash for near-term needs. More stocks generally mean greater exposure to market fluctuations; bonds have interest-rate and credit risks of their own. There is no single allocation that fits everyone of the same age.
Consider a diversified index fund or an appropriately selected target-date fund only after reading its objectives, asset allocation, fees and risks. Target-date funds change their mix over time, but funds with the same date in their names may hold different investments. Investor.gov explains target-date fund limitations.
Review the cost of your plan and investments. Expense ratios and other account or advisory fees reduce the dollars left to grow. Use the fee disclosures and SEC fee guidance before deciding that two investments have equivalent costs.
Step 4: Plan withdrawals, not just the account balance
What the 4% rule actually assumes
The widely cited 4% rule starts with a withdrawal equal to 4% of the portfolio value at retirement in year one. In later years, the original dollar withdrawal is adjusted for inflation; you do not automatically withdraw a fresh 4% of the account’s then-current market value each year.
The guideline was developed from historical portfolios and a roughly 30-year retirement horizon. It is not an insured income product or a guarantee that a given balance will last. Retirement length, asset allocation, costs, taxation, inflation and the order of investment returns all influence sustainability. Recent forward-looking withdrawal research reaches somewhat different starting-rate estimates under different assumptions.
| Portfolio-funded annual spending | 4.0% illustration | 3.5% illustration |
|---|---|---|
| $20,000 | $500,000 | $571,429 |
| $30,000 | $750,000 | $857,143 |
| $40,000 | $1,000,000 | $1,142,857 |
These are simple reciprocals of the withdrawal assumption, not precise retirement recommendations. Read the site’s 4% Rule guide for assumptions and Morningstar’s retirement-income research for an example of how projections and spending flexibility affect conclusions.
Why early losses are different during retirement
When you regularly withdraw money, a large market decline early in retirement can force sales of more shares to cover the same spending. Even if returns later recover, you may have fewer invested assets left to participate. This is sequence-of-returns risk; holding an appropriate short-term reserve, diversifying and having room to trim discretionary withdrawals can help manage it, although none removes market risk.
Explore the site’s Sequence of Returns Risk guide. Include taxes on withdrawals, Medicare-related expenses and future healthcare costs in your own retirement cash-flow plan.
What changes if you want to retire before 59½?
Early retirement creates two separate needs: funding additional years without earned income and arranging access to funds before standard retirement-account withdrawal ages. Taxable brokerage holdings, cash reserves and eligible distribution exceptions may all play roles. Do not assume every withdrawal before age 59½ triggers the same tax treatment.
Traditional retirement-account distributions made before 59½ are generally subject to ordinary income tax and may also face a 10% additional tax unless an exception applies. Roth IRA regular contribution withdrawals have different ordering and taxation rules from Roth earnings. Some workplace-plan distributions after separation from service in or after the year you turn 55, and certain substantially equal periodic payments, can qualify for exceptions. Read the IRS rules on early IRA distributions and obtain tax guidance for account-specific withdrawals.
Before cashing out a workplace retirement account after a job change, compare leaving the balance in the plan, a direct rollover to a new employer’s plan, and a direct rollover to an IRA. Direct eligible rollovers can avoid the withholding associated with payments sent to you, but the account type and destination affect tax treatment. The IRS explains rollover rules.

Retirement planning frequently asked questions
How much money do I need to retire?
Estimate expenses, subtract dependable income and calculate the amount investments must fund. A 4% first-year withdrawal illustration would put a $30,000 annual portfolio-funded gap at $750,000, but test other rates and retirement durations. A universal dollar figure ignores individual circumstances.
Is the 4% rule safe for everyone?
No. It is a historical planning framework with important assumptions, not a guaranteed payout. Retirement horizon, market conditions, spending flexibility, allocation, fees and taxes change the risk of running out of money.
Can I contribute to both a 401(k) and an IRA in 2026?
Potentially yes. Workplace-plan deferral limits and IRA limits are separate. However, traditional IRA deductibility, direct Roth IRA eligibility, compensation limits and plan rules may affect the tax benefit or amount you can contribute.
Should I choose traditional or Roth contributions?
Compare taxes now against plausible taxes when money is withdrawn, while considering eligibility and flexibility. Qualified Roth withdrawals may be tax-free; traditional withdrawals are generally taxable. A combination can sometimes help manage tax uncertainty.
Does a $500-per-month savings plan guarantee about $502,000 in 30 years?
No. That result assumes every deposit is made at month-end and a fixed 6% nominal annual rate is compounded monthly for 360 months. Market returns are uneven, and inflation, fees and taxes can lower purchasing power or account value.
What if I have not started saving yet?
Start with the money available after essential expenses, test affordable contribution levels, use employer matching contributions when feasible and periodically increase savings as circumstances permit. For cash-flow planning, see the Budgeting & Saving hub and Emergency Fund guide.

Bottom line
A retirement plan is strongest when it links realistic spending, actual income sources, feasible contributions and explicit risk assumptions. Revisit those figures regularly rather than relying on a single retirement number, investment-return assumption or withdrawal rule. A calculator can test the arithmetic; it cannot guarantee the future.
