Planning Your Retirement Savings Timeline
Most people have no idea if they're saving enough for retirement. They contribute to a 401(k) because their employer offers one, pick a percentage that feels reasonable, and hope it works out. This retirement savings calculator replaces hope with numbers by projecting your balance at retirement based on your contributions, employer match, expected returns, and timeline.
The most common mistake? Underestimating how much you'll need. Someone planning to spend $50,000 per year in retirement needs roughly $1.25 million saved (using the 4% withdrawal rule). If your calculator shows you're on track for $600,000, you've got a gap to close—either by saving more, working longer, or adjusting expectations.
This calculator shows your projected balance in both nominal dollars (what your statement will show) and real dollars (adjusted for inflation to show purchasing power). That $1 million in 30 years won't buy what $1 million buys today—the real number tells you what it'll actually be worth.
What Drives Your Retirement Balance
Your contribution rate matters more than you'd think. Bumping from 6% to 10% of salary doesn't just add 67% more savings—it adds 67% more employer match too (if they match your contributions). Over 30 years, that difference can mean $300,000 or more.
Employer match is free money most people leave on the table. If your employer matches 50% up to 6% of salary, contributing only 4% forfeits thousands annually. Always contribute at least enough to capture the full match before directing money elsewhere.
Time horizon is your biggest advantage when you're young and your biggest constraint when you're older. Someone starting at 25 has 40 years for compounding to work. Starting at 45 means aggressive savings are the only path to the same destination.
Expected return should be conservative. Stock markets have historically averaged around 7% after inflation, but that includes plenty of years with losses. Using 6-7% for projections keeps expectations realistic. Don't count on 10%.
Inflation assumption of 2-3% is typical. This erodes purchasing power—a $50,000 annual retirement income needs to be $90,000 in 30 years just to maintain the same lifestyle at 2% inflation.
Two Planning Scenarios
Example 1: Early Career (Age 28)
Inputs: $70,000 salary, 8% contribution ($5,600/year), 50% employer match up to 6% ($2,100/year), current balance $15,000, retiring at 65, 6.5% expected return, 2.5% inflation.
Result: Projected balance at 65: $1,420,000 nominal, about $570,000 in today's purchasing power.
Interpretation: At a 4% withdrawal rate, that's roughly $23,000 per year in today's dollars—enough to supplement Social Security but possibly not enough alone. Increasing contributions to 12% would push the real balance toward $750,000.
Example 2: Late Starter (Age 48)
Inputs: $95,000 salary, 15% contribution ($14,250/year), employer match 100% up to 4% ($3,800/year), current balance $120,000, retiring at 67, 6% expected return, 2.5% inflation.
Result: Projected balance at 67: $730,000 nominal, about $480,000 in today's purchasing power.
Interpretation: That's roughly $19,000 per year in sustainable withdrawals. Combined with Social Security (maybe $25,000-30,000 annually), this person could cover $45,000-50,000 in annual expenses. Adding catch-up contributions at age 50 (an extra $7,500/year for 401(k)s) would push the balance higher.
When This Calculator Helps (and When It Doesn't)
Use this calculator when:
- You're trying to decide how much of your salary to contribute
- You want to see if your current savings rate is on track
- You're comparing employer plans with different match structures
- You need to know how much extra you'd need to save after a late start
- You're deciding between contributing more to 401(k) vs. paying down debt
This calculator won't:
- Account for Social Security benefits (enter those separately as income)
- Model market volatility—returns are smoothed into a constant rate
- Calculate taxes on withdrawals (depends on account type and your future bracket)
- Predict healthcare costs or unexpected expenses
2025 Contribution Limits (IRS)
- 401(k) / 403(b) employee limit: $23,500 (under 50), $31,000 (age 50+)
- IRA limit: $7,000 (under 50), $8,000 (age 50+)
- Roth IRA income phaseout: Begins at $150,000 (single), $236,000 (married filing jointly)

Assumptions in This Calculator
- Returns are constant each year (reality: markets fluctuate)
- Contributions happen at regular intervals without interruption
- Salary grows at a steady rate you specify
- Employer match is deposited at the same time as your contributions
- No early withdrawals or loans against the balance
These simplifications make projections easier to understand but won't match your actual experience exactly. Real portfolios have good years and bad years. The projection shows an average path, not a guarantee.

Common Questions
How much should I save for retirement each month?
A common guideline is saving 15% of your gross income for retirement, including any employer match. If you start in your 20s, 10-12% may be sufficient; starting in your 40s might require 20-25% to catch up. The actual amount depends on when you want to retire, your expected Social Security benefits, and your desired retirement lifestyle. Use this calculator with your specific numbers—someone earning $80,000 saving 15% contributes $1,000/month, which at 7% returns for 30 years grows to approximately $1.2 million.
What's the difference between a 401(k) and an IRA?
A 401(k) is offered through your employer with higher contribution limits ($23,500 in 2025, plus $7,500 catch-up if 50+) and potential employer matching—free money you should always capture. An IRA you open yourself with lower limits ($7,000, or $8,000 if 50+) but more investment choices and typically lower fees. Both come in Traditional (tax-deferred) and Roth (tax-free withdrawals) versions. The optimal strategy: contribute to your 401(k) up to the full employer match, then max out an IRA, then return to max your 401(k).
Should I pick Traditional or Roth for my retirement accounts?
Choose Traditional if you're in a high tax bracket now and expect lower taxes in retirement—you get an upfront deduction and pay taxes later. Choose Roth if you're early in your career (lower bracket now) or expect higher future taxes—you pay taxes now but withdrawals are tax-free. Many financial planners suggest splitting contributions between both to hedge against future tax uncertainty. If unsure, Roth is often better for younger workers since tax-free growth for 30-40 years is powerful.
How do I know if I'm on track for retirement?
Common benchmarks by age: 1x your salary saved by 30, 3x by 40, 6x by 50, 8x by 60, and 10x by 67. These assume you want to replace about 80% of pre-retirement income. If you're behind, don't panic—increasing your savings rate by even 2-3% makes a significant difference over time. This calculator helps you see whether your current trajectory meets your specific goals based on your actual numbers, not generic rules.
When can I access my retirement money without penalties?
Generally, you can withdraw from 401(k)s and Traditional IRAs penalty-free at age 59½. Roth IRA contributions (not earnings) can be withdrawn anytime tax and penalty-free. Early withdrawals before 59½ typically face a 10% penalty plus income taxes, though exceptions exist for disability, first-time home purchases ($10,000 from IRAs), and certain hardships. The Rule of 55 lets you access 401(k) funds if you leave your job at 55 or later. Required Minimum Distributions start at age 73 for Traditional accounts.
What return rate should I assume for retirement planning?
For long-term planning, 6-7% (after inflation) is reasonable for a stock-heavy portfolio based on historical averages. More conservative planners use 5-6%. Avoid assuming 10%+ returns—while the S&P 500 has averaged about 10% historically, that's before inflation, and future returns may be lower. The calculator lets you test different scenarios. Being conservative is safer: if markets outperform your assumption, you retire earlier or with more money than expected.
