What If Your $200,000 Keeps Earning Money After You Retire in China?

— Cross-Border Retirement Ledger, Part Six

In the previous article, we took apart our $200,000 retirement model and reached an important conclusion: $200,000 is not a retirement safety threshold. It is simply a number whose meaning changes with retirement income, medical costs, the age at which disability begins, the duration of care, and the cost of long-term care.

But that model contained one important assumption—one we deliberately left in place.

We assumed that the $200,000 earned nothing.

That is certainly conservative, but it is not particularly realistic. Most retirees do not convert their entire portfolios to cash and leave the money sitting untouched in a bank account for the next 20 or 30 years. Even retirees who no longer want the investment risk they accepted when they were younger may keep part of their assets in bonds, CDs, money market funds, or other relatively conservative investments while leaving another portion invested in stocks or funds.

That changes the question.

If the $200,000 continues earning a return throughout retirement, how much does that change the retirement ledger?

Potentially, quite a lot.

A 4% Return Comes Surprisingly Close to the Care Shortfall

Start with the baseline model from the previous article.

A retiree has $1,500 a month in Social Security and other stable retirement income, plus $200,000 in financial assets. At an exchange rate of RMB 6.7 to the dollar, a long-term-care facility charging RMB 15,000 a month costs about $2,239.

The retiree’s $1,500 monthly income covers most of that amount, leaving $739 a month to be funded from savings.

That is about $8,868 a year.

Now suppose the $200,000 portfolio earns a long-term nominal return of 4%.

Four percent of $200,000 is $8,000 in the first year.

Something interesting immediately appears:

The $8,000 investment return is already surprisingly close to the $8,868 annual long-term-care shortfall.

In our earlier zero-return model, ten years of care would take roughly $89,000 from principal.

But if the assets themselves continue generating returns, the result clearly will not be the same.

This highlights an easily overlooked feature of retirement planning. Assets are not simply a pile of money waiting to be spent. They can also be a pool of capital that continues producing income and appreciation.

If stable retirement income covers much of a retiree’s regular expenses, while investment returns cover part of the long-term-care shortfall, principal may decline much more slowly.

But this also creates an obvious temptation:

If a 4% return nearly covers the care shortfall, does that mean the $200,000 principal never has to be touched?

No.

“Averaging 4%” Is Not the Same as “Receiving 4% Every Year”

If a bank promises a fixed 4% annual interest rate on a deposit, the calculation is straightforward.

An investment portfolio does not work that way.

A portfolio that averages 4% over the long run might gain 12% in the first year, lose 8% in the second, rise 6% in the third, and barely move in the fourth. Over many years, the average may approach 4%. But a retiree’s monthly care bill does not stop arriving when the market falls.

That creates one of the central risks in retirement investing: sequence-of-returns risk.

Imagine two retirees who ultimately experience the same average investment return over 20 years.

The first encounters a bull market early in retirement. The portfolio grows before major withdrawals begin.

The second retires into a bear market and simultaneously has to withdraw money for medical and long-term-care expenses.

Even if their average 20-year investment returns ultimately turn out to be identical, the amount of money they have left can be very different.

The reason is straightforward.

If the market falls and an investor does not need to withdraw money, there is time to wait for a recovery. But if a retiree has to sell investments to pay for care during a downturn, those assets are gone. They cannot participate in the eventual rebound.

So the greatest danger to a retirement portfolio may not be that its long-term return is too low. It may be that the market performs worst precisely when the retiree needs the money most.

That is why we cannot simply multiply $200,000 by 4% and treat the resulting $8,000 as guaranteed annual income for long-term care.

What Happens If the $200,000 Really Does Keep Growing?

To see how much investment returns matter, we can add a simple dynamic experiment to the model.

Suppose a retiree begins at age 70 with $200,000 in financial assets and $1,500 a month in stable retirement income. We continue to budget $1,500 a year for routine medical expenses. At age 80, the retiree begins needing long-term care costing RMB 15,000 a month. At age 85, we also deduct a one-time $60,000 reserve for a major illness.

Here we need one important real-world assumption: once long-term disability care begins at age 80, we continue counting the cost of that care for as long as the retiree remains alive. If we calculate through age 90, that means ten years of long-term care. If we calculate through age 95, it means fifteen years.

At RMB 6.7 to the dollar, RMB 15,000 a month is about $2,239. After subtracting $1,500 in monthly retirement income, the portfolio must cover about $739 a month, or $8,868 a year. Add $1,500 in annual routine medical expenses, and the portfolio must cover approximately $10,368 a year once long-term care begins.

For the moment, we deliberately leave inflation out of the calculation and hold the exchange rate and cost of care constant. We also use a deliberately simple calculation: at the beginning of each year, the portfolio grows at the assumed rate of return, after which that year’s medical and care expenses are deducted. At age 85, another $60,000 is deducted for the major-illness reserve.

We then give the same retiree four hypothetical steady annual returns: 0%, 2%, 4%, and 6%.

The differences are striking.

With no investment return, the original $200,000 falls to roughly $21,000 by age 90. If long-term care continues to age 95, the portfolio is exhausted before then.

With a steady 2% return, roughly $99,000 remains at age 90. If care continues through age 95, the balance keeps falling, leaving roughly $55,000.

With a steady 4% return, approximately $217,000 remains at age 90. Even after another five years of long-term care, roughly $207,000 remains at age 95. In this deliberately simplified model, a return of around 4% comes close to offsetting the annual drain created by routine medical care and the long-term-care shortfall.

At a steady 6% return, the effect becomes even more dramatic. The portfolio reaches roughly $394,000 by age 90 and could still grow to around $465,000 by age 95 despite continuing long-term care.

These numbers are not investment forecasts. Nor do they suggest that retirees who earn 4% or 6% no longer need to worry about long-term care.

They are a mathematical experiment.

What the experiment reveals is that two forces are acting on retirement assets at the same time: investment returns and compounding are pushing the portfolio upward, while medical and long-term-care expenses are pulling it downward.

Whichever force becomes stronger determines whether principal grows, declines gradually, or is eventually exhausted.

More importantly, the experiment shows why it is not enough to ask, “How many years of care can $200,000 pay for?” If the portfolio continues generating returns throughout retirement, the more useful question becomes:

While long-term-care expenses continue, how much of the annual medical and care shortfall can investment returns offset?

The real world, of course, will never be as smooth as these numbers. Stocks will not reliably return 4% or 6% every year. Long-term-care prices will not remain unchanged for fifteen years. Medical expenses will not stay fixed at today’s levels, and the dollar-renminbi exchange rate will not remain permanently at 6.7.

It is also worth recognizing that needing long-term disability care continuously from age 80 to 95 is itself a severe long-term-care scenario. That brings us back to one of the central findings of this series: for retirement assets, the greatest financial danger may not be a single major illness, but surviving that illness or disability and then requiring care for many more years.

The point of this calculation, therefore, is not to predict exactly how much money someone will have at age 95. It is to show how dramatically the outcome of a $200,000 retirement portfolio changes once both investment returns and the duration of long-term care are allowed to operate at the same time.

A 4% Investment Return Is Not the “4% Withdrawal Rule”

There is another distinction that is especially important.

A portfolio earning an average annual return of 4% is not the same thing as the retirement-planning concept commonly known as the “4% withdrawal rule.”

The 4% withdrawal rule addresses how much a retiree might withdraw from a portfolio in the first year of retirement, with subsequent withdrawals generally adjusted for inflation, while attempting to make the portfolio last through a long retirement.

It asks: How much can I spend?

The 4% investment-return assumption in our model asks a different question.

It asks: How much does the portfolio earn?

The two are not interchangeable.

Recent retirement-income research illustrates the distinction. Morningstar’s 2025 research estimated a 3.9% starting safe withdrawal rate for new retirees seeking inflation-adjusted spending over a 30-year retirement with a 90% probability of success. The number happens to be close to 4%, but not because the portfolio is assumed to “earn 3.9% every year.” A sustainable withdrawal rate must also account for market volatility, asset allocation, inflation, and the length of retirement.

So an investment portfolio averaging 4% does not imply that someone can spend 4% every year without ever reducing principal.

They are two fundamentally different calculations.

A Realistic Model Has to Put Inflation and Risk Back In

If we want to move the retirement model closer to reality, the next question cannot simply be how much the portfolio earns.

We also have to ask: What is the real return after inflation?

Suppose a portfolio earns a nominal 4% over the long run, while medical and long-term-care costs rise by 3% a year. That 4% return is much less powerful than it first appears.

The problem becomes even more complicated because retirees do not experience one uniform “inflation rate.”

Food might rise by 2%, housing by 4%, while medical and long-term-care costs may rise faster. A retiree living primarily in China while receiving income and holding assets in U.S. dollars also faces another variable: exchange-rate risk.

If the dollar strengthens, the same $1,500 in Social Security buys more renminbi. If the dollar weakens over a long period, the long-term-care shortfall grows.

Taxes matter as well.

Assets held in a traditional IRA, 401(k), Roth IRA, taxable brokerage account, or bank deposit can produce very different amounts of spendable after-tax income, even when the headline investment return looks identical.

Then there is an even more practical question: How much of an 80-year-old retiree’s portfolio should remain exposed to volatile investments when major medical or long-term-care expenses could arise at any time?

If $60,000 has been designated as a major-illness reserve, putting the entire $60,000 into stocks and then assuming it will earn 6% over the long run conflicts with the very purpose of calling it a reserve.

A reserve has to provide liquidity and safety first. Return comes second.

A realistic retirement portfolio may therefore need different layers: money likely to be needed soon should remain liquid and relatively stable; money that may be needed several years from now can be invested more conservatively; and only money unlikely to be needed for a decade or longer may be able to tolerate substantially more market risk.

At that point, the question is no longer simply whether $200,000 is enough.

It becomes: How should that $200,000 be held?

What May Matter Most Is Not the Principal, but the Annual Shortfall

Over the course of these six articles, the original question has gradually changed.

At first, we asked:

“How much money do you need to retire in China without Chinese health insurance?”

We eventually discovered that the question was too simple.

Retirement security is not determined by a single asset number. What matters is the recurring gap between income and expenses.

If someone receives $2,500 a month in stable retirement income while long-term care costs $2,239, the care bill itself does not rapidly consume principal, even if the retiree does not have an enormous portfolio.

By contrast, someone may have $500,000 in assets but little stable income. If a U.S. nursing home costs close to $10,000 a month, those assets can still disappear remarkably quickly.

Assets become most vulnerable when recurring expenses remain above stable income and investment returns cannot close the gap.

Seen this way, the $200,000 model takes on a more complete structure.

Social Security and other stable retirement income form the first layer of cash flow. Investment returns form the second. Financial principal is the third. Medical and long-term-care expenses continually draw against those resources.

The important question is therefore no longer simply, “How many years can I spend $200,000?”

It is:

Under different investment returns, inflation rates, exchange rates, and long-term-care costs, how much of that $200,000 will remain at age 80, 90, or 95?

That is a dynamic retirement model.

And it leads naturally to one final question for this series.

If a retiree ultimately does not spend the entire $200,000—and perhaps still retains a substantial portfolio at death because of stable retirement income, lower medical and care costs in China, and long-term investment returns—then the final entry in the cross-border retirement ledger is no longer simply about how much retirement costs.

It becomes:

At the end of two different retirement paths, how much is left?

That is an entirely different calculation.

This article is part of Chinese Voices’ “Cross-Border Retirement Ledger” series. Rather than asking which country is “better” for retirement, the series looks at health care, long-term care, income, and assets to examine the financial risks of cross-border retirement—one calculation at a time.
