Retirement Calculator
Estimate how much you need to retire comfortably and whether your savings are on track.
How the Retirement Calculator Works
This calculator projects your retirement savings by growing your current savings and monthly contributions at your expected annual return rate until your desired retirement age.
Projected Savings at Retirement: Uses the compound interest formula with monthly contributions to project future growth.
Amount Needed: Estimates how much you need at retirement to fund your desired annual income through your life expectancy, adjusted for inflation. The calculation assumes your retirement savings continue to earn returns (at a reduced rate) during retirement.
The 4% Rule: A common guideline suggesting you can withdraw 4% of your savings annually in retirement with low risk of running out over a 30-year period. The monthly income figure shown uses this rule as a reference.
This calculator provides estimates only. Actual results depend on market performance, tax situation, Social Security benefits, and other factors not modeled here.

Understanding Retirement Planning
Retirement planning is the process of determining how much money you need to save and invest to maintain your desired lifestyle after you stop working. It is one of the most important financial planning exercises because it involves long time horizons, multiple variables, and significant uncertainty. Starting early is the single most powerful advantage due to compound interest.
The three pillars of retirement income are Social Security, employer-sponsored retirement plans (401k, pension), and personal savings. Social Security replaces roughly 40% of pre-retirement income for average earners, meaning you need personal savings to fill the remaining gap. The exact amount depends on your desired lifestyle, location, healthcare needs, and how long you live.
A common rule of thumb is that you need 25 times your desired annual retirement income saved (based on the 4% withdrawal rule). If you want $60,000/year in retirement, you need approximately $1.5 million saved. This sounds daunting but is achievable with consistent contributions over 30+ years thanks to compound growth.
Step-by-Step Retirement Calculation Example
A 30-year-old with $50,000 saved, contributing $500/month, earning 7% annually, wanting $60,000/year in retirement at age 65:
Step 1: Project savings at 65 (35 years of growth): $50,000 grows to $534,000. $500/month contributions grow to $1,013,000. Projected total: $1,547,000.
Step 2: Adjust desired income for inflation (3% over 35 years): $60,000 x (1.03)^35 = $169,000/year needed in 2061 dollars.
Step 3: Calculate amount needed for 25 years of retirement (age 65-90): Using a 4% real return rate, you need approximately $2,630,000.
Step 4: Compare: $1,547,000 projected vs $2,630,000 needed = shortfall of $1,083,000. To close the gap, increase contributions to approximately $900/month or adjust retirement expectations.
Retirement Saving Strategies
Maximize employer match: If your employer matches 401k contributions (e.g., 50% match up to 6%), always contribute at least enough to get the full match. A 50% match is an instant 50% return on your money -- the best guaranteed return available anywhere.
Use tax-advantaged accounts: 401k and traditional IRA contributions reduce your taxable income today. Roth 401k and Roth IRA contributions grow tax-free and withdrawals are tax-free in retirement. In 2026, you can contribute up to $23,500 to a 401k and $7,000 to an IRA ($30,500 and $8,000 if 50+).
Increase contributions with every raise: Save half of every raise. If you get a 4% raise, increase your retirement contribution by 2%. You still enjoy a lifestyle improvement while accelerating your savings. Over a career, this strategy can add hundreds of thousands to your retirement nest egg.
The 4% Rule: In retirement, withdrawing 4% of your portfolio in the first year (adjusting for inflation each subsequent year) has historically provided a high probability of your money lasting 30 years. For a $1.5 million portfolio, this means $60,000/year ($5,000/month) in retirement income.

Frequently Asked Questions
How much do I need to retire?
A common target is 25 times your desired annual retirement income (based on the 4% rule). For $60,000/year, you need $1.5 million. For $80,000/year, you need $2 million. Adjust for Social Security income, which may cover 30-40% of your needs.
What is the 4% rule?
The 4% rule states you can withdraw 4% of your retirement portfolio in year one, then adjust for inflation each year, with a high probability of your money lasting 30 years. With $1 million, you can safely withdraw $40,000/year. Some experts now suggest 3.5% for added safety.
401k vs IRA: which is better?
Start with your 401k up to the employer match (free money). Then consider a Roth IRA for tax-free growth ($7,000/year limit). Then go back to the 401k up to the maximum ($23,500/year). The 401k has higher limits; the IRA offers more investment choices.
Traditional vs Roth: which should I choose?
Traditional contributions reduce taxes now; you pay taxes on withdrawals. Roth contributions use after-tax money; withdrawals are tax-free. Choose Roth if you expect to be in a higher tax bracket in retirement, or Traditional if you are in a high bracket now. Many experts recommend having both for tax flexibility.
What if I start saving late?
It is never too late to start. If you begin at 40, you can still accumulate significant savings by 65 with aggressive contributions. Take advantage of catch-up contributions after 50 ($7,500 extra in 401k, $1,000 in IRA). Consider working 2-3 extra years, which both adds savings and reduces the withdrawal period.
How much should I contribute to retirement?
Save 15-20% of gross income including employer match. If you start at 25, 15% is usually sufficient. Starting at 35 requires 20-25%. Starting at 45 may require 30%+. At minimum, contribute enough to get your full employer match.
How do I account for Social Security?
You can estimate your Social Security benefits at ssa.gov. The average benefit in 2026 is about $1,900/month ($22,800/year). Plan for Social Security to cover 30-40% of retirement needs, and use personal savings for the rest. Some planners recommend planning without Social Security as a conservative approach.
What about healthcare costs in retirement?
Healthcare is one of the largest retirement expenses. A 65-year-old couple may need $300,000-$400,000 for healthcare over their retirement. Medicare covers much but not all -- you will need supplemental insurance (Medigap), dental, and vision coverage. An HSA (Health Savings Account) is an excellent way to save tax-free for future healthcare costs.
