Why a $1.8 Million Nest Egg at 65 Only Buys $54,000 of Real Annual Spending

A married couple turning 65 this year with $1.8 million saved and $44,000 in combined annual Social Security has done almost everything right. They are also about to discover that their big retirement portfolio number and their actual spending power live in two very different worlds.

Apply a 3.8% gross withdrawal to that $1.8M and the portfolio kicks off at roughly $68,000. Add Social Security and the gross household income is about $112,000. That sounds like a comfortable middle-class retirement. But the amount this couple can actually direct toward groceries, gas, golf, and grandkids lands closer to $54,000, or about $4,500 a month.

For context, Schwab’s annual participant study pegged the retirement “magic number” at $1.6 million in 2025, down from $1.8 million in 2024. This couple has hit the older, higher target. But they still need to understand what it actually buys.

Walking $112,000 Down to $54,000

Start with $112,000 of gross household income and subtract:

1. Federal income tax. After the 2026 standard deduction of $32,200 for married filing jointly, taxable income lands inside the 12% bracket, which runs to $100,800 for joint filers. Once the taxable share of Social Security is layered in, expect roughly $6,000 to $8,000 in federal tax.
2. State income tax. At an average 5% state rate, plan on $4,000 to $5,500. Nine states levy nothing, so this line is the most variable.
3. Medicare Part B. The 2026 standard Part B premium is about $203 per month, or roughly $4,870 a year for two enrollees.
4. Medicare Part D. Plan premiums plus standard surcharges typically run $600 to $1,000 a year per couple.
5. IRMAA risk. A joint MAGI above $218,000 triggers Part B and Part D surcharges. At $112K this couple sits well under the line, but one oversized Roth conversion or capital-gain year can push them over and tack on about $81 per spouse per month at the first tier.
6. Out-of-pocket healthcare. Dental, vision, hearing, supplemental coverage, and copays. Budget $8,000 to $12,000 a year.
7. Long-term-care reserve. Self-funding a future LTC event requires setting aside roughly $8,000 to $10,000 annually, or paying premiums for hybrid LTC coverage.

What is left? About $54,000 of money this couple can actually spend. For reference, the average U.S. household spent $78,535 in 2024.

Inflation must also be considered. The 2026 Social Security COLA of 2.8% does not fully recapture medical inflation, which historically runs faster than the broader index.

Fortunately, the safe-withdrawal backdrop has actually improved. The 10-year Treasury sits at 4.4% and the Fed funds upper bound is 3.75%, so a 3.8% gross withdrawal is conservative against risk-free yields. The harder drag is tax and healthcare friction.

Potential Moves

IRMAA-aware withdrawal sequencing

The most expensive accidental mistake at this income level is crossing the $218,000 joint MAGI line. Pull from the taxable brokerage account first, use Roth withdrawals to top up spending without raising MAGI, and stagger large traditional IRA distributions across calendar years. At the first tier, the Part B premium jumps to about $284 per month per spouse, and IRMAA follows you for the full calendar year you trigger it.

Guyton-Klinger guardrails

Instead of locking in a flat 3.8% for life, use a withdrawal band. If the portfolio falls 20% below its starting trajectory, cut spending 10%. If it climbs 20% above, give yourself a raise. Historically these rules support starting rates above the rigid 4% benchmark because they adapt to sequence-of-returns risk.

QCDs at 73

Once required minimum distributions begin at age 73, Qualified Charitable Distributions let you send IRA dollars directly to charity. The distribution counts toward the RMD but never enters MAGI, which can be a great way for keeping IRMAA, Social Security taxation, and bracket creep in check while still giving.

To wrap up, audit the gap before celebrating the big portfolio number. Build one spreadsheet that walks gross income down to spendable cash using your state, your insurance, and your healthcare assumptions. Then model a single Roth conversion year and watch what happens to MAGI. Treat $1.8 million as a $54,000 paycheck with a long-term-care self-insurance fund attached. Planning around that real number can be the difference between a relaxed 30-year retirement and a stressful one.
