Calculate retirement savings and income projections
A retirement calculator projects how much money you'll have at retirement and whether it's enough to maintain your lifestyle. It uses the 4% rule to estimate sustainable withdrawal rates and helps identify savings gaps early enough to adjust your strategy.
Retirement Income = Savings × 4% (sustainable withdrawal rate)
The 4% rule suggests withdrawing 4% of your portfolio in year one of retirement, then adjusting for inflation annually. Based on historical data, this approach has a high probability of lasting 30 years. $1 million savings = $40,000/year withdrawal. Some experts now suggest 3-3.5% for added safety given longer lifespans.
A common rule: 25× your annual expenses (based on 4% rule). Need $50,000/year? Target $1.25 million. Another approach: 10-12× final salary by age 67. Factor in Social Security (check ssa.gov for estimates), pensions, and reduced expenses in retirement. Many retirees spend less as they age.
Start as early as possible! Starting at 25 vs 35 can mean 2× more retirement savings due to compound interest. But it's never too late - even starting at 50 with aggressive savings can build significant wealth. Max out employer matches immediately regardless of age.
401(k): Employer-sponsored, higher limits ($23,000/year in 2024 + $7,500 catch-up if 50+), often with employer match. IRA: Individual account, lower limits ($7,000/year + $1,000 catch-up), more investment choices. Both offer tax advantages. Traditional = tax-deferred; Roth = tax-free growth. Use both if possible.
Social Security replaces about 40% of pre-retirement income for average earners. Maximum benefit at full retirement age is about $3,800/month (2024). Claiming at 62 reduces benefits 30%; waiting until 70 increases them 24%. Check ssa.gov for personalized estimates. Don't rely solely on Social Security.
Catch-up strategies: Maximize catch-up contributions after 50, delay Social Security, work 2-3 years longer, reduce expenses now, downsize housing, consider part-time work in retirement. Even small changes help - working to 67 vs 65 can increase savings 10-15%. It's about progress, not perfection.
