Retirement Savings Calculator

The employer 401k match is an immediate, guaranteed return on your investment that no other financial product can replicate. If your employer matches 50% of contributions up to 6% of salary, contributing 6% gives you an instant 50% return on that 6% — before any market growth. Not capturing the full match is equivalent to leaving a portion of your compensation on the table every pay period.

To find your match rate, log into your 401k provider portal or ask your HR department for the Summary Plan Description. Look for language describing the match formula — common structures include dollar-for-dollar up to a percentage, 50 cents per dollar up to a percentage, or a fixed percentage of salary regardless of your contribution. Enter these figures in the calculator above to see exactly how much the match adds to your monthly retirement savings.

Capturing the full employer match should be your first retirement optimization step before any other strategy — before paying extra on low-interest mortgage debt, before taxable brokerage investing, and before any other financial goal except a small emergency fund. There is no rational reason to invest in a taxable account while leaving employer match money unclaimed.

The optimal order for retirement savings maximizes after-tax wealth by prioritizing accounts with the strongest tax advantages. The recommended sequence is: first, contribute enough to capture the full employer match; second, max a Health Savings Account if you have a high-deductible health plan — the HSA offers a triple tax advantage (deductible contributions, tax-free growth, tax-free withdrawals for qualified medical expenses) and can function as a stealth retirement account after age 65; third, max your IRA ($7,000 in 2026, or $8,000 if 50 or older); fourth, max remaining 401k contributions up to the $23,500 limit; fifth, invest in a taxable brokerage account.

Following this order ensures every dollar receives the maximum available tax benefit before moving to less advantaged accounts. A dollar in a Roth IRA that grows tax-free for 30 years is worth significantly more after tax than a dollar in a taxable brokerage account where dividends and capital gains are taxed annually.

Traditional versus Roth within each account type depends on your current tax bracket versus expected retirement bracket. Younger workers in the 12% or 22% brackets often benefit from Roth contributions. High earners in the 32% bracket or above often benefit from traditional contributions that reduce current taxable income. Many planners recommend tax diversification — holding both account types — to manage taxable income flexibly in retirement.

If you are self-employed, a SEP IRA or Solo 401k can shelter far more income than an IRA alone. The Solo 401k allows employee deferrals plus employer profit-sharing, potentially reaching over $70,000 in total contributions for high-income solo business owners in 2026.

Lifestyle inflation — the tendency to increase spending proportionally with income — is one of the most powerful forces working against retirement savings. The most effective countermeasure is committing before each raise to direct at least 50% of the increase to retirement contributions before the higher income becomes normalized in your spending patterns. If you receive a $5,000 raise, increasing your 401k contribution by $200 per month captures nearly half while still allowing a meaningful lifestyle improvement.

Many 401k plans offer auto-escalation features that increase your contribution rate by 1% per year automatically. Enabling this feature removes the behavioral barrier of manually increasing contributions each year. A 1% annual increase compounded over 20 years, combined with market growth and employer matching, has a dramatic effect on your final balance — often hundreds of thousands of dollars.

The psychology matters as much as the math: you never miss money you did not spend. Increasing contributions immediately when a raise takes effect means you experience the raise in take-home pay only partially, while your retirement account captures the rest invisibly. Over a career, this single habit separates those who retire comfortably from those who wonder where decades of good income went.

Every additional year of work provides a double benefit: one more year of contributions added to your portfolio, and one fewer year of withdrawals depleting it. Delaying retirement from 62 to 67 while maintaining contributions can increase your nest egg by 30 to 50% or more depending on your savings rate and market returns — often more impactful than any other single change.

Phased retirement — reducing to part-time work rather than stopping entirely — dramatically reduces the required nest egg because you need less portfolio income to cover expenses. Working 20 hours per week in early retirement at $25 per hour provides $2,000 per month of income, reducing your required nest egg by approximately $600,000 at the 4% withdrawal rate. Many retirees find part-time work in a field they enjoy more fulfilling than full leisure.

The non-financial benefits of continued purposeful activity in early retirement are substantial and well-documented. Maintaining social connections, cognitive engagement, and a sense of structure contributes to physical and mental health outcomes that reduce healthcare costs — creating a positive feedback loop with your financial plan.

The 4% rule originated from research by financial planner William Bengen and was later validated by the Trinity Study, which analyzed historical U.S. stock and bond returns to determine safe withdrawal rates. The rule states that a retiree can withdraw 4% of their portfolio in the first year of retirement, adjust that amount for inflation each subsequent year, and have a high probability of the portfolio lasting 30 years.

In practice, the 4% rule means a $1,000,000 portfolio supports $40,000 in first-year withdrawals, increasing to $40,800 in year two with 2% inflation, and so on. The rule assumes a diversified portfolio of roughly 50 to 75% stocks and the remainder in bonds, annual rebalancing, and no adjustments for market conditions — which is both its strength as a simple heuristic and its weakness as a rigid strategy.

Critics argue the 4% rule may be too aggressive given lower expected future returns, longer retirements due to increasing life expectancy, and the sequence of returns risk described below. Financial researcher Michael Finke and others have suggested 3% to 3.5% may be more appropriate for retirees with 40-year horizons or those retiring into elevated market valuations.

Dynamic withdrawal strategies offer an alternative to fixed inflation-adjusted withdrawals. The Guyton-Klinger guardrails approach, for example, reduces withdrawals after poor market years and allows increases after strong years — adapting to actual portfolio performance rather than assuming historical averages will continue. These strategies can support higher initial withdrawal rates in favorable conditions while protecting against depletion in adverse ones.

The sequence in which you withdraw from different account types in retirement significantly affects how long your money lasts and how much you pay in taxes. The conventional optimal order for most retirees is: first, taxable brokerage accounts — allowing tax-advantaged accounts to continue compounding; second, traditional 401k and IRA accounts for ordinary income needs; third, Roth accounts last to preserve tax-free growth as long as possible.

Taxable accounts are often withdrawn first because long-term capital gains are taxed at preferential rates (0%, 15%, or 20% depending on income), and cost basis is returned tax-free. Letting traditional and Roth accounts grow tax-deferred and tax-free respectively maximizes the compounding benefit of tax-advantaged shelter.

Required Minimum Distributions (RMDs) from traditional 401k and IRA accounts begin at age 73 under current law, forcing withdrawals regardless of whether you need the income. RMDs can push retirees into higher tax brackets and increase Medicare premiums through IRMAA surcharges. Planning Roth conversions in the years between retirement and RMD age — when income is lower — can reduce lifetime taxes significantly.

Roth accounts should generally be withdrawn last because every dollar of Roth growth is tax-free, and Roth IRAs have no RMDs during the owner's lifetime. Preserving Roth assets as long as possible maximizes tax-free compounding and provides a tax-free resource for large expenses, healthcare costs, or legacy planning.

Sequence of returns risk is the risk that poor market returns in the early years of retirement — when you are also making withdrawals — have a disproportionately large negative impact on portfolio longevity compared to the same poor returns occurring later. A 30% market decline in year one of retirement combined with 4% withdrawals can permanently impair a portfolio that would have survived the same decline in year 15.

The most practical mitigation strategy is maintaining a cash buffer of one to two years of essential expenses in a high-yield savings account or money market fund, separate from your invested portfolio. During market downturns, you draw from this cash reserve rather than selling depressed investments, giving your portfolio time to recover without locking in losses.

Flexible spending — reducing discretionary withdrawals in down market years rather than rigidly increasing withdrawals for inflation — is the other key mitigation. Research consistently shows that retirees who can reduce spending by 10 to 15% during bear markets dramatically improve portfolio survival rates. Building this flexibility into your retirement budget from the start makes it far easier to execute when markets decline.
