Years Lasting = Savings / (Withdrawal – Growth)
The retirement calculator compounds savings annually and calculates sustainable withdrawal rates to ensure retirement funds last through life expectancy.

Frequently Asked Questions
How much should I save for retirement?
Most retirement calculators recommend saving 10-15% of gross income throughout your career. This retirement calculator shows exactly how much you need based on your retirement age and lifestyle. A common rule: replace 70-80% of pre-retirement income. If you earn $75,000 annually, target $52,500-$60,000 yearly retirement income. Use this retirement calculator to determine your specific savings target based on current age, retirement age, life expectancy, and expected investment returns. The retirement calculator factors in inflation, investment growth, and Social Security to show if you’re on track.
How long will my retirement savings last?
This retirement calculator determines how long savings last by dividing your retirement nest egg by annual withdrawals, adjusted for investment returns and inflation. Using the 4% rule: withdraw 4% of retirement savings annually, and money should last 30+ years. With $1 million saved, withdraw $40,000 yearly. This retirement calculator shows exact longevity based on your withdrawal rate, investment returns, inflation, and life expectancy. The retirement calculator helps you avoid outliving your savings by modeling different scenarios and withdrawal strategies.
What is the 4% retirement withdrawal rule?
The 4% rule means withdrawing 4% of retirement savings in year one, then adjusting for inflation annually. This retirement calculator uses the 4% rule as a baseline: $500,000 saved allows $20,000 first-year withdrawal. Research shows 4% withdrawal rates have 95% success over 30-year retirements. However, this retirement calculator lets you test different withdrawal rates. Conservative planners use 3-3.5%, while aggressive use 5%. The retirement calculator shows how each rate affects retirement savings longevity under various market conditions.
When can I retire?
You can retire when your retirement savings generate enough income to cover expenses. This retirement calculator determines retirement readiness by comparing projected savings to income needs. Calculate: annual expenses ÷ 0.04 = savings needed (using 4% rule). Needing $50,000 annually requires $1.25 million saved. Use this retirement calculator to project when you’ll reach your savings target based on current contributions and investment returns. The retirement calculator shows your retirement date based on realistic assumptions about savings growth.
How much will I have when I retire?
This retirement calculator projects retirement savings using compound interest: FV = PV(1+r)^n + PMT × [((1+r)^n – 1) / r], where FV is future value, PV is current savings, r is annual return, n is years, PMT is contributions. Starting with $50,000, contributing $500 monthly for 30 years at 7% return yields approximately $1.13 million at retirement. The retirement calculator accounts for your current age, retirement age, existing savings, contribution amounts, and expected investment returns to project exact retirement savings accumulation.
What return should I expect on retirement investments?
Historical stock market returns average 10% annually, bonds 5-6%, while balanced portfolios return 7-8%. This retirement calculator uses realistic return assumptions based on asset allocation. Conservative retirement portfolios (heavy bonds) expect 4-5% returns. Moderate retirement portfolios (60/40 stocks/bonds) expect 6-7%. Aggressive retirement portfolios (heavy stocks) expect 8-9%. Use this retirement calculator with different return rates to see how investment performance affects retirement readiness. The retirement calculator shows best-case, likely, and conservative scenarios.
Should I include Social Security in retirement planning?
Yes, include Social Security in retirement calculations. This retirement calculator has optional Social Security input. Average Social Security retirement benefit is $1,827 monthly ($21,924 annually). Your benefit depends on earnings history and claiming age. Claiming at 62 reduces benefits 30%, while waiting until 70 increases benefits 24%. Use this retirement calculator with estimated Social Security to see total retirement income. The retirement calculator shows how Social Security reduces savings withdrawal needs, helping retirement savings last longer.
How does inflation affect retirement savings?
Inflation erodes retirement savings purchasing power over time. This retirement calculator accounts for inflation by reducing real returns and increasing future income needs. With 3% inflation, $50,000 annual expenses become $67,196 in 10 years, $90,306 in 20 years. The retirement calculator adjusts all future values for inflation impact. Use 2-3% inflation in this retirement calculator for conservative planning. Historical inflation averages 3%, though recent years saw 4-8%. The retirement calculator shows how inflation affects retirement savings longevity.
What’s better: Roth IRA or Traditional IRA for retirement?
Roth IRAs provide tax-free retirement withdrawals; Traditional IRAs offer upfront tax deductions. Use this retirement calculator with both scenarios. In high tax bracket now, low bracket in retirement: Traditional IRA better. In low bracket now, high bracket retirement: Roth IRA better. This retirement calculator shows after-tax retirement income for comparison. Roth advantages: no required minimum distributions, tax-free growth, tax-free inheritance. Traditional advantages: immediate tax savings, lower current taxes. The retirement calculator helps compare total retirement savings accumulation under both strategies.
Can I retire early with this calculator?
Yes, this retirement calculator supports early retirement planning. For early retirement (before 59½), plan penalty-free withdrawals using Roth IRA contributions, 72(t) distributions, or taxable account savings. The retirement calculator shows required savings for early retirement based on longer retirement duration. Early retirement at 55 requires 35+ years of savings vs 30 years at 60. Use this retirement calculator with conservative return assumptions and higher savings rates for early retirement. The retirement calculator indicates if current savings trajectory supports early retirement goals.
