Retirement Calculator: How Much Do You Really Need to Retire?

How much money do you need to retire? It is the question that keeps financial planners employed and the rest of us awake at night. The answer ranges from "a million dollars" to "it depends" — neither of which is particularly helpful. Let us break this down into concrete numbers and practical guidelines so you can find your actual retirement target.

The 4% Rule: A Simple Starting Point

The most widely cited retirement guideline is the 4% rule, based on a 1994 study by financial advisor William Bengen. The rule states: in your first year of retirement, withdraw 4% of your total portfolio. In subsequent years, adjust that amount for inflation. Following this rule, a portfolio historically lasted at least 30 years in most market conditions. Working backward: if you need $50,000 per year in retirement, you need $1,250,000 saved (50,000 / 0.04). If you need $80,000 per year, your target is $2,000,000. This gives you a ballpark, but the real number depends on many personal factors.

How Much Will You Actually Spend?

The common advice that you need 70-80% of your pre-retirement income is a rough estimate. Some retirees spend less because they no longer commute, buy work clothes, or save for retirement. Others spend more because they travel, pursue hobbies, or face higher healthcare costs. The most accurate approach is to estimate your actual retirement budget. List your expected monthly expenses: housing, food, healthcare, insurance, transportation, entertainment, travel, and miscellaneous. Subtract any expenses you will no longer have (like a mortgage, if it will be paid off). Add expenses that may increase, particularly healthcare. This gives you a much more realistic annual spending estimate than any rule of thumb.

The Social Security Factor

Social Security will provide a portion of your retirement income, but it will not cover everything. The average Social Security benefit in 2026 is approximately $1,900 per month, or $22,800 per year. The maximum benefit for someone claiming at full retirement age is about $3,800 per month. If your retirement spending goal is $60,000 per year and Social Security provides $22,800, you need your portfolio to generate $37,200 per year. Using the 4% rule, that means you need about $930,000 in personal savings — significantly less than the full $1.5 million. Check your estimated Social Security benefit at ssa.gov to refine your calculations.

Healthcare: The Wild Card

Healthcare is the most unpredictable and potentially devastating retirement expense. A 65-year-old couple retiring in 2026 can expect to spend approximately $315,000 on healthcare throughout retirement, according to Fidelity estimates. Medicare covers a lot, but not everything — dental, vision, hearing, and long-term care are significant gaps. Long-term care alone can cost $4,000-9,000+ per month. If you retire before 65, you will need to bridge the gap with private insurance, which can easily cost $500-1,500+ per month per person. Factor healthcare into your retirement number realistically, not optimistically.

When Do You Want to Retire?

The age you retire dramatically changes how much you need. Retiring at 55 instead of 65 means your portfolio needs to last 10 extra years, you lose 10 years of contributions and growth, you need 10 years of private health insurance before Medicare, and you may face penalties for early withdrawal from retirement accounts. Use our Retirement Calculator at money.now.to to compare scenarios at different retirement ages. You might find that working even 2-3 extra years significantly reduces the savings you need, thanks to more contributions, more compounding, and fewer years of withdrawals.

The Retirement Number by Age

General savings benchmarks by age help gauge whether you are on track. By age 30, aim to have 1x your annual salary saved. By 40, aim for 3x. By 50, target 6x. By 60, you should have 8-10x your annual salary. By retirement at 67, aim for 10-12x. If you earn $75,000 per year, your retirement target is roughly $750,000-900,000. These are guidelines, not requirements — your actual needs depend on your spending, Social Security, pension income, and healthcare situation.

The Inflation Problem

A dollar today will buy significantly less in 20-30 years. At 3% annual inflation, $50,000 in today's dollars becomes roughly $90,000 in 20 years and $121,000 in 30 years. Your retirement savings need to account for this erosion of purchasing power. This is why keeping a portion of your retirement portfolio in stocks (even during retirement) is important — bonds and cash may not outpace inflation over long periods. Use our Inflation Calculator at money.now.to to understand how inflation affects your specific retirement timeline.

Investment Returns: Be Realistic

Many retirement calculators assume 10-12% annual returns, which is the historical average for U.S. stocks. However, after inflation, real returns are closer to 7-8%. And returns are never linear — you might get 25% one year and lose 15% the next. Sequence-of-returns risk (experiencing losses early in retirement) can devastate a portfolio. Use conservative assumptions: 6-7% before inflation, or 3-4% real returns. It is better to end up with too much money than too little. Our Investment Calculator at money.now.to lets you model different return scenarios.

Strategies to Close the Gap

If your retirement number feels impossibly high, several strategies can help. Maximize employer 401(k) matching — it is free money. Increase your savings rate by 1% each year; you will barely notice the difference. Pay off your mortgage before retiring to drastically lower your monthly expenses. Consider geographic arbitrage — retiring in a lower-cost area or country. Delay Social Security to age 70 for a roughly 76% higher benefit compared to claiming at 62. Work part-time in early retirement to reduce portfolio withdrawals during the critical first years.

The Bottom Line

Your retirement number is deeply personal. It depends on when you retire, where you live, how much you spend, your health, your Social Security benefit, and your risk tolerance. The 4% rule gives you a starting framework: multiply your annual retirement spending (minus Social Security and pensions) by 25. Then adjust for your specific situation. The most important step is to start planning now. Use our Retirement Calculator at money.now.to to model your personal scenario and create a concrete savings target. Time and compound interest are your greatest allies — but only if you start.
