Will I Run Out of Money After Divorce?

Last reviewed: May 2026

This question keeps people up at night for a reason: it has a real answer, and you can find it before you sign a settlement. The answer isn't a number on the settlement document. It's whether your post-divorce cash flow — income against expenses, year by year, for the next 30 years — actually works.

Most divorce settlements look fine on paper at the moment they're signed. The reason people run out of money is that the picture changes over time, and the variables that change are predictable if you look for them.

The four shifts that break post-divorce budgets

Shift 1: Income drops faster than expenses do.

After a divorce, household income often falls 30–50%. Expenses rarely fall by the same amount, especially in the first few years, because two households cost more than one (rent, utilities, internet, transportation, kid-related duplicated costs). Many people walk into year one assuming “we'll just spend less” and discover the floor isn't where they thought it was.

Shift 2: Support ends, and the budget assumed it wouldn't.

If your post-divorce budget depends on alimony or child support, you have an expiration date you may not be focused on. Child support typically ends at 18 (or 19 if the child is still in high school full-time, depending on your state). Alimony has its own clock — in many states, the duration is tied to the length of the marriage. In California, for marriages under 10 years, alimony usually runs for half the marriage length. In Illinois, the duration is set by a statutory multiplier. In Pennsylvania, post-divorce alimony has no formula and depends entirely on what the court finds “necessary.”

What this means in practice: if you're 45, married 12 years, and your post-divorce budget assumes alimony for 7 years (roughly 60% of the marriage length), you need to know what happens in year 8. If your earning capacity hasn't recovered by then, the budget breaks.

Shift 3: Healthcare costs you weren't paying suddenly hit.

If you were on your spouse's employer health plan, you lose that coverage at divorce. Your immediate options are:

• COBRA, which lets you stay on the ex's plan for up to 36 months after divorce — but you pay the full premium plus a 2% admin fee, often $700–$1,500/month for a single adult
• The ACA marketplace, where premiums depend on income and the plan you pick — typically $400–$800/month for a healthy 45-year-old before subsidies, which can lower the cost substantially if your post-divorce income qualifies
• Your own employer's plan, if you work somewhere that offers coverage

Many people are surprised by what they pay for healthcare in the first year of divorce. Build the actual number into your budget; don't assume your spouse's plan continues.

Shift 4: Retirement contributions stop, and the math doesn't forgive you.

This is the long-term killer. If you stop contributing to retirement during the divorce and the years immediately after — to make the mortgage work, to pay the lawyers, to weather the income drop — you don't just lose those contributions. You lose 20+ years of compounding on those contributions. A $10,000 annual contribution skipped at age 45, at a 7% return, is worth roughly $76,000 by age 65. Skip five years of contributions, and you've foregone $380,000 of retirement balance.

The Social Security divorced-spouse benefit you may not know about

If you were married at least 10 years and you're not currently remarried, you may be entitled to up to 50% of your ex-spouse's Social Security benefit at full retirement age, paid from Social Security's general funds. Your claiming this benefit doesn't reduce your ex's payment. The Social Security Administration doesn't notify them. It's a federal entitlement under 20 CFR § 404.331.

The 10-year rule is strict — 9 years and 364 days of marriage doesn't qualify. The duration is measured from the wedding date to the date the divorce is legally finalized.

If you're considering a divorce and you're close to the 10-year mark, this is a fact your financial planner should put in front of you. (The decision of whether to wait is yours; the existence of the rule is not optional.)

You also need:

• To be at least 62 to claim
• To be currently unmarried (or to have remarried after age 60 for survivor benefits)
• For your own Social Security benefit to be lower than the divorced-spouse benefit (otherwise you just get your own, which is higher)
• A two-year waiting period after the divorce is finalized, unless your ex is already collecting

The four-question test for whether your settlement lasts

Before you sign a settlement, work through these four questions. The honest answers tell you whether you're likely to run out of money.

1. What's my full annual cost of living in year 1 of the divorce, including housing, healthcare, taxes, retirement contributions, and a real emergency fund? Not a hopeful number — a real one, with line items.
2. What's my income in year 1, including alimony, child support, and any earned income — after taxes and after benefit costs? The after-tax number is what you actually have to spend.
3. In year 7 (or whenever your support payments end), what changes? Does your earned income replace the support? If not, by how much does the budget shrink?
4. By age 65, what's my retirement balance, given the contributions I'll actually be able to make? Run this with realistic return assumptions (6–7%, not 10%) and inflation factored in.

If the answer to any of these is “I don't know” or “it doesn't quite work but I'll figure it out,” you're at risk. Settlements signed in that state of uncertainty are how people end up running out of money in their 60s.

How DivorceSmart Pro helps

The free calculators on this site can answer pieces of this — your guideline alimony, your child support estimate, whether the mortgage fits your income. The Pro report builds the full 30-year cash flow projection: year-by-year income, expenses, support payments, retirement contributions, and ending retirement balance, with the four shifts above modeled in. It tells you, in concrete numbers, whether the settlement you're considering actually works long-term.

Frequently asked questions

How much income do I actually need after divorce?

A common rule is that you need roughly 70–80% of your former joint household income to maintain a similar standard of living as a single household — because some costs (housing, utilities, transportation) don't scale down proportionally to the income drop. If your prior joint household income was $200,000, you may need $140,000–$160,000 to feel comparably comfortable. This is a starting point, not a target — your actual number depends on your housing decision, kids, and lifestyle.

Can I get alimony for life?

In most states, no — but in some long-marriage scenarios, yes. California, Illinois, and several other states allow indefinite alimony for marriages of “long duration” (usually 10 years or longer), but “indefinite” doesn't mean permanent — it means the court retains jurisdiction and may modify or terminate the award if circumstances change. Pennsylvania post-divorce alimony has no formula; the court sets duration based on what's “reasonable under the circumstances.” If lifelong support is a settlement goal, your attorney needs to know.

What happens to my health insurance after the divorce?

You lose coverage on your ex's employer plan as of the divorce date (sometimes the end of that month). You have 60 days to elect COBRA. The ACA marketplace open enrollment is annual but a divorce is a “qualifying life event” that opens a special enrollment window. Don't go uninsured — even briefly — if you can avoid it.

Should I take more of the cash and less of the retirement account?

It depends on what you'll need the money for and when. Retirement accounts grow tax-deferred and compound for decades, but you can't easily access them before age 59½ without taxes (the QDRO penalty exception, discussed on the house vs. 401(k) page, is a one-time window). Cash is liquid but doesn't grow. The right split depends on whether you need money to live on for the next 5 years or to retire on for the next 30. The Pro report runs both scenarios.

What's a “marital lifestyle” analysis and do I need one?

It's a detailed accounting of your historical spending — rent, food, vacations, kids' activities, everything — to establish what the “marital standard of living” was. In states like California where the standard of living is a key factor in alimony decisions, this analysis can drive the support number. It's something the Pro report can scaffold for you, but a CPA or CDFA usually finalizes it for litigation.
