How Is Retirement Planning Different When You Are Single?

Why Do Single Retirees Need a Higher Savings Rate?

A married couple shares housing costs, utilities, car insurance, health insurance (potentially), and food expenses. A single person pays the full cost alone. Housing — the largest retirement expense — doesn't halve when you go from two people to one.

Tax brackets compound the issue. In 2025, the 22% bracket for singles starts at $47,150 of taxable income. For married filing jointly, it starts at $94,300 — exactly double. But a single person's expenses are not half of a couple's. This means singles reach higher marginal rates faster.

Social Security: A single person gets only their own benefit. No spousal benefit, no survivor benefit. If your PIA is $2,500/month and you delay to 70, you get $3,100/month. That's your entire Social Security income. A couple with PIAs of $2,500 and $1,800 could receive $6,100/month combined at optimal claiming.

What Adjustments Does the Analysis Make for Single Retirees?

The Monte Carlo engine automatically adjusts several parameters:

1. Tax brackets: Uses single filer brackets (narrower than MFJ) 2. Social Security: Models only the individual's benefit (no spousal/survivor) 3. Standard deduction: $15,700 vs. $31,400 for couples 65+ (2025) 4. Healthcare: Full cost borne by one person (no family plan savings) 5. Housing: Full mortgage/rent/property tax on single income 6. End age: Models to 95 (same as couples, but no second-to-die consideration)

The result: single retirees typically need 15-20% more savings relative to their spending than a comparable married couple to achieve the same Monte Carlo success rate.

What Strategies Are Especially Important for Single Retirees?

1. Long-term care planning: No spouse to provide care. Self-insurance threshold is lower because the entire portfolio must support one person plus potential LTC costs.

2. Social Security maximization: With no spousal or survivor benefit to consider, the decision is simpler — delay as long as possible (usually to 70) to maximize the only benefit you'll receive.

3. Emergency fund: Larger relative to income, since there's no second earner to fall back on.

4. Estate planning: Beneficiary designations are especially critical — without a surviving spouse, assets could go to unintended recipients via state intestacy laws.

5. Roth conversions: Single filers hit higher brackets faster, making the conversion window (between retirement and RMDs) even more valuable for reducing lifetime taxes.
