Retirement Calculator – How Much Do I Need to Retire?

A common guideline is to save 10-12 times your pre-retirement annual salary. For example, if you earn $75,000 per year, aim for $750,000 to $900,000 in retirement savings. However, the exact amount depends on your desired lifestyle, expected Social Security benefits, healthcare costs, and where you plan to live. Use our retirement calculator above to get a personalized estimate based on your specific situation.

The 4% rule (from the Trinity Study) suggests that if you withdraw 4% of your retirement portfolio in the first year and adjust for inflation each subsequent year, your savings should last at least 30 years. For example, with $1,000,000 saved, you could withdraw $40,000 in year one. Our calculator uses this rule to estimate your sustainable retirement income.

Compound interest is the most powerful factor in growing retirement savings. It means you earn returns not only on your original contributions but also on accumulated interest. For example, investing $500 per month at a 7% annual return from age 25 to 65 would grow to approximately $1.2 million — even though you only contributed $240,000. Starting early is the single biggest advantage you can give yourself.

The best time to start saving for retirement is as early as possible. Starting at age 25 instead of 35 can nearly double your retirement savings due to compound interest. Even small contributions of $100-200 per month in your 20s can grow significantly over 40+ years. If you haven't started yet, the second-best time is today — every year of delay means you need to save significantly more.

Financial experts recommend contributing at least enough to get your full employer match (typically 3-6% of salary), as this is essentially free money. Ideally, aim to save 15-20% of your gross income for retirement across all accounts (401(k), IRA, etc.). The 2025 401(k) contribution limit is $23,500 ($31,000 if age 50 or older with catch-up contributions).

Yes, Social Security should be part of your plan, but it shouldn't be your only source of retirement income. The average monthly Social Security benefit in 2025 is approximately $1,900, which replaces about 40% of pre-retirement income for average earners. Delaying benefits from age 62 to 70 increases your monthly benefit by about 77%. Our calculator estimates your benefit based on your salary and claiming age.

According to the Federal Reserve, average retirement savings by age are roughly: Age 30 — $45,000; Age 40 — $130,000; Age 50 — $255,000; Age 60 — $426,000; Age 65 — $496,000. However, these are averages and many experts recommend higher targets. The goal is to have 1x your salary saved by 30, 3x by 40, 6x by 50, 8x by 60, and 10x by 67.

Inflation reduces the purchasing power of your money over time. At 3% annual inflation, $100 today will only buy about $41 worth of goods in 30 years. That's why our calculator adjusts for inflation — showing you the real value of your retirement income. To combat inflation, invest in growth-oriented assets and plan for higher expenses during retirement.

A retirement savings gap is the difference between how much income you'll need in retirement and how much your savings can actually provide. To close the gap, you can: (1) increase monthly contributions, even by $100-200; (2) delay retirement by a few years; (3) maximize employer matching; (4) reduce planned retirement expenses; or (5) delay Social Security benefits to get a higher monthly payment.

Our calculator uses standard financial formulas including monthly compound interest, SSA bend-point methodology for Social Security estimates, the 4% safe withdrawal rule, and inflation-adjusted projections. It provides reliable estimates for planning purposes. However, actual results will vary based on market performance, tax situation, and life changes. We recommend revisiting your plan annually and consulting a financial advisor for personalized advice.
