Example: A 35-year-old earning $75,000 with $50,000 saved, contributing $500/month at 7% returns, will accumulate approximately $1.1M by age 65. The 4% rule suggests this supports $44,000/year in withdrawals.
Tip: Small contribution increases have huge long-term impact. Adding $100/month at age 35 adds roughly $120,000 to your retirement balance by 65.

About Retirement Calculator
Formula
Future Value = PV(1+r)^n + PMT × [(1+r)^n - 1] / r Combines current savings growth with future contribution accumulation, where PV is current balance, PMT is contributions, r is return rate, and n is years.
Current Standards: Financial advisors suggest saving 10-15% of gross income for retirement. The 4% withdrawal rule, derived from Trinity Study, assumes a 50/50 stock-bond portfolio over 30 years.
Frequently Asked Questions
How much do I need to retire?
Multiply your desired annual retirement income by 25 (the inverse of 4%). For $60,000/year, you need $1.5M. This excludes Social Security and pensions, which reduce the amount needed. Account for healthcare costs ($300,000+ for a couple over retirement) in your planning.
What's a realistic investment return assumption?
Use 6-7% for aggressive portfolios (80%+ stocks) and 4-5% for conservative allocations. These are after-inflation (real) returns if you're not separately adjusting for inflation. Historical stock returns average 10% nominal, 7% real, but future returns may differ.
Should I prioritize paying off debt or saving for retirement?
Always contribute enough to get your employer's 401(k) match (free money). Then pay off high-interest debt (8%+). After that, maximize retirement contributions before paying extra on low-rate debt. A 6% mortgage effectively costs 4.5% after tax benefits vs. 7%+ investment returns.
How does Social Security affect my savings target?
The average Social Security benefit is $1,900/month ($22,800/year) in 2026. Maximum benefit at full retirement age is $4,018/month. Subtract expected Social Security from your income needs before calculating required savings. A $60,000/year goal becomes $37,200 with average Social Security.
What if I want to retire early (before 59.5)?
Early retirement requires accessing funds before traditional retirement accounts allow penalty-free withdrawals. Strategies include taxable brokerage accounts, Roth IRA contribution withdrawals (always penalty-free), Rule of 55 for 401(k)s, and SEPP/72(t) distributions. You'll also need to bridge healthcare until Medicare at 65.
