How Much Do I Need to Retire? Your Complete 2026 Guide
The answer depends on three things: where you'll live, what lifestyle you want, and when you plan to retire. We break it all down — with the formulas, benchmarks, and real numbers you actually need.
There Is No Universal "Retirement Number" — But There Is a Formula
You've probably heard "$1 million" floated as the magic retirement goal. It's a myth. A retiree in Hawaii needs over $2.1 million to sustain the same lifestyle that costs $658,000 to fund in Arkansas. Someone who wants to travel extensively needs far more than someone who plans a quiet rural retirement.
The honest answer starts with four inputs: your expected annual spending, your retirement state, your Social Security income, and your withdrawal strategy. This guide walks through each one.
💡 The Simple Starting Formula: Your retirement number = (Annual spending − Annual Social Security income) ÷ 0.04. This is the 4% withdrawal rule. Example: Need $60,000/year, expect $25,000 from Social Security → ($60,000 − $25,000) ÷ 0.04 = $875,000 needed.
The 4% Rule: Your Baseline Calculator
The 4% rule, developed by financial planner William Bengen in 1994 and validated by the Trinity Study, states that you can safely withdraw 4% of your retirement savings in Year 1, then adjust upward for inflation each year, with a high probability that your savings will last 30+ years.

| Annual Spending Need (After SS) | Required Savings (4% Rule) | Required Savings (3.5% Rule) |
|---|---|---|
| $20,000/year | $500,000 | $571,000 |
| $30,000/year | $750,000 | $857,000 |
| $40,000/year | $1,000,000 | $1,143,000 |
| $50,000/year | $1,250,000 | $1,429,000 |
| $60,000/year | $1,500,000 | $1,714,000 |
| $75,000/year | $1,875,000 | $2,143,000 |
| $100,000/year | $2,500,000 | $2,857,000 |

📌 2026 Update: The original creator of the 4% rule, William Bengen, now suggests 4.7% may be appropriate based on current market data — meaning $1M in savings could support $47,000/year instead of $40,000. However, most financial planners still recommend using 4% as a conservative baseline, especially for longer retirements.

The 80% Rule: Estimating Your Retirement Income Need
Financial planners commonly recommend replacing 70–80% of your pre-retirement income in retirement. The logic: your mortgage may be paid off, you'll stop commuting, and you won't be saving for retirement anymore. However, healthcare costs often rise significantly, so 80% is safer for most people.
