Retirement Future Value Calculator: Plan Your 401(k), IRA & Pension
Estimate your retirement savings with employer matching, inflation adjustment, and detailed year-by-year projections. See how your 401(k), IRA, and personal contributions grow over time with the power of compound interest.
How Much Do You Need to Retire?
Determining how much you need for retirement depends on several factors: your desired lifestyle, expected expenses, healthcare costs, Social Security benefits, and how long your retirement might last. Here are the most widely-used benchmarks:
- The 80% Rule: Plan to replace 80% of your pre-retirement income each year. If you earn $80,000, you'd need $64,000 per year in retirement.
- The 4% Rule: Withdraw 4% of your retirement portfolio each year. To generate $40,000 annually, you'd need $1,000,000 saved.
- The 10x Rule: By age 67, aim to have 10–12 times your annual salary saved. Earning $100,000? Target $1,000,000 to $1,200,000.
- Fidelity Milestones: Save 1x your salary by 30, 3x by 40, 6x by 50, 8x by 60, and 10x by 67.
Understanding 401(k) Plans
A 401(k) is an employer-sponsored retirement savings plan that lets you contribute pre-tax dollars from your paycheck. Your investments grow tax-deferred until you withdraw them in retirement.
2026 401(k) Contribution Limits
| Category | 2026 Limit | Notes |
|---|---|---|
| Employee Contribution | $23,500 | Standard annual limit |
| Catch-Up (Age 50+) | $7,500 | Additional for those 50 and older |
| Super Catch-Up (Age 60–63) | $11,250 | SECURE 2.0 Act provision |
| Total (Employee + Employer) | $70,000 | Combined annual limit |
How Employer Matching Works
Many employers match a portion of your 401(k) contributions — this is essentially free money. Common matching formulas include:
- Dollar-for-dollar up to 3%: Employer matches 100% of your contributions up to 3% of your salary.
- 50 cents per dollar up to 6%: Employer adds $0.50 for every $1.00 you contribute, up to 6% of your salary. This is the most common formula.
- Flat percentage: Employer contributes a fixed percentage (e.g., 3%) regardless of your contribution level.
IRA vs 401(k): Which Is Better?
Both IRAs and 401(k) plans offer tax advantages for retirement savings, but they differ in key ways. Many investors use both to maximize their tax-advantaged savings.
| Feature | 401(k) | Traditional IRA | Roth IRA |
|---|---|---|---|
| 2026 Contribution Limit | $23,500 | $7,000 | $7,000 |
| Catch-Up (50+) | +$7,500 | +$1,000 | +$1,000 |
| Employer Match | Yes | No | No |
| Tax Treatment | Pre-tax contributions; taxed on withdrawal | Tax-deductible contributions; taxed on withdrawal | After-tax contributions; tax-free withdrawals |
| Income Limits | None | Deduction phases out at higher incomes | $161,000 single / $240,000 married (2026) |
| RMDs | Required at 73 | Required at 73 | None during owner's lifetime |
| Investment Options | Limited (employer-selected) | Broad (stocks, bonds, ETFs, etc.) | Broad (stocks, bonds, ETFs, etc.) |
| Early Withdrawal Penalty | 10% before age 59½ | 10% before age 59½ | Contributions anytime; earnings 10% before 59½ |
| Best For | Employees with employer match | Those wanting immediate tax deduction | Younger savers expecting higher future tax rate |
Optimal strategy: Contribute to your 401(k) up to the employer match, then max out a Roth IRA, then go back and max out the 401(k). This diversifies your tax exposure in retirement.
The Power of Employer Matching
Employer matching is one of the most powerful wealth-building tools available. It's literally free money added to your retirement savings, and it compounds over decades just like your own contributions.
Example: The Impact of a 50% Match
Consider Sarah, age 30, earning $75,000/year with a 401(k) that matches 50% up to 6% of salary:
| Detail | Annual Amount |
|---|---|
| Sarah's contribution (6% of $75,000) | $4,500 |
| Employer match (50% of $4,500) | $2,250 |
| Total annual contribution | $6,750 |
| Years to retirement (age 65) | 35 years |
| Assumed return | 7% annually |
| Projected balance at 65 | $1,001,813 |
| Without employer match | $667,876 |
| Extra from employer match alone | +$333,937 |
The employer match boosted Sarah's retirement fund by $333,937 — even though the employer's total contribution over 35 years was only $78,750. The rest is compound interest growth on those matched dollars.
Inflation's Impact on Retirement Savings
While your retirement account might show an impressive number by the time you retire, inflation quietly erodes the purchasing power of every dollar. Understanding the difference between nominal and real (inflation-adjusted) values is crucial for realistic retirement planning.
At a 3% average annual inflation rate:
| Time Horizon | $1,000,000 Nominal | Real Purchasing Power | Purchasing Power Lost |
|---|---|---|---|
| 10 years | $1,000,000 | $744,094 | -25.6% |
| 20 years | $1,000,000 | $553,676 | -44.6% |
| 30 years | $1,000,000 | $411,987 | -58.8% |
| 40 years | $1,000,000 | $306,557 | -69.3% |
This is why our retirement calculator shows both the nominal projected value and the inflation-adjusted real value. When setting retirement goals, always think in today's dollars to avoid a nasty surprise.

Frequently Asked Questions About Retirement Planning
-
A common guideline is to save 10–12 times your pre-retirement annual salary by age 67. For example, if you earn $80,000 per year, aim for $800,000 to $960,000 in retirement savings. The 4% rule suggests you can safely withdraw 4% of your portfolio annually, so $1 million would provide roughly $40,000 per year in retirement income. However, your actual needs depend on desired lifestyle, healthcare costs, location, Social Security benefits, and other income sources.
-
Employer matching means your company contributes additional money to your 401(k) based on your own contributions. A typical match is 50% of your contributions up to 6% of your salary. For example, if you earn $60,000 and contribute 6% ($3,600/year), your employer adds $1,800/year. This is essentially free money. Always contribute at least enough to get the full employer match — otherwise you're leaving money on the table. Employer matches usually have a vesting schedule (3–6 years) before you fully own the matched funds.
-
A Traditional 401(k) uses pre-tax dollars — you get a tax break now, but pay taxes when you withdraw in retirement. A Roth 401(k) uses after-tax dollars — no tax break now, but withdrawals in retirement are completely tax-free. If you expect to be in a higher tax bracket in retirement, Roth is better. If you expect a lower tax bracket, Traditional is better. Many advisors recommend contributing to both ("tax diversification") since future tax rates are unpredictable.
-
Inflation erodes purchasing power over time. At 3% annual inflation, $1 million in 30 years has the equivalent purchasing power of about $412,000 in today's dollars. This means you'll need significantly more in nominal terms to maintain the same standard of living. Our calculator shows both nominal and inflation-adjusted projections so you can plan realistically. A 7% return with 3% inflation gives you a real return of approximately 4%.
-
As early as possible. Thanks to compound interest, starting at age 25 instead of 35 can nearly double your retirement savings — even with the same monthly contribution. For example, saving $500/month at 7% from age 25 to 65 yields about $1.2 million, while starting at 35 yields only about $567,000. That extra decade of compounding adds over $600,000 despite only $60,000 more in contributions. If you haven't started yet, the best time is today.
-
For long-term retirement planning, 7% is commonly used as an average annual return for a diversified stock portfolio (roughly the S&P 500 historical average after inflation). More conservative estimates use 5–6%. A balanced 60/40 stock/bond portfolio has historically returned about 7–8% before inflation. If you're closer to retirement with a bond-heavy portfolio, 4–5% may be more realistic. Our calculator defaults to 7% but you can adjust based on your specific investment allocation.
-
Yes! You can contribute to both a 401(k) and an IRA in the same year. In 2026, you can put up to $23,500 into your 401(k) and up to $7,000 into an IRA ($8,000 if you're 50+). However, if you have a 401(k), your Traditional IRA deduction may be limited based on income. There are no income limits for Roth 401(k) contributions, but Roth IRA contributions phase out at $161,000 (single) and $240,000 (married filing jointly). The optimal strategy: maximize employer match in 401(k) first, then fund a Roth IRA, then return to max out the 401(k).
-
Generally, withdrawing from a 401(k) or Traditional IRA before age 59½ triggers a 10% early withdrawal penalty on top of regular income taxes. Exceptions include: disability, first-time home purchase (IRA, up to $10,000), substantially equal periodic payments (72t), and certain hardship withdrawals. With a Roth IRA, you can always withdraw your contributions (not earnings) penalty-free at any time since you already paid taxes on them. Early withdrawal also costs you future compound growth — a $10,000 withdrawal at 30 could be worth $75,000+ by age 65.
