Asset allocation

What stock/bond allocation should you have at 50?

There's no single "right" stock/bond split at 50 — it's a trade-off between growth and stability. Running thousands of historical market sequences on a retirement portfolio, a higher stock allocation raises the median result but widens the range of outcomes. Here's the honest picture across allocations.

More stocks: higher median, wider swings — the core trade-off
In this stress test, a 100% stock mix has a much higher median ending balance than 20% stocks, but a far wider spread between the good and bad cases. A middle allocation trades some upside for a steadier ride.

Monte Carlo outcomes by allocation

Ending balance (today's dollars) across 700 historical-market simulations for a retiree drawing a moderate income. The 10th percentile is the "bad luck" case; the 90th is "good luck":

How to actually choose

The table shows the trade-off; your allocation should follow from your situation, not a single "best" number:

A common age-based rule of thumb is "110 minus your age in stocks," but it's only a starting point. These figures assume a retiree with modest Social Security drawing a moderate income; a rule of thumb can't see your full picture — model yours in the calculator's Simulation Tools.

The bigger risk at 50 is playing it too safe

At fifty the instinct is often to start dialing down stocks. But if you retire in your sixties, the money may need to last thirty years or more — a horizon over which inflation, not a single bad year in the market, is the threat most likely to erode your standard of living. A portfolio tilted heavily toward bonds and cash can feel calm and still quietly fail to keep pace with rising prices.

A rule like 110 minus your age puts you around 60% stocks here, but treat that as a starting point, not a ceiling. With a decade or more before you touch the money, you have time to ride out downturns and let compounding do the heavy lifting.

The trade-off is genuine — more stocks raise your median outcome but widen the range of results. The goal isn't to max out risk. It's to avoid locking in a mix so conservative that it can't outrun inflation across a long retirement, which is its own way of running out of money.

Common questions

What is the best stock/bond allocation at 50?

There isn't one "best" — it's a trade-off. In this stress test, more stocks raise the median outcome but widen the range of results. A middle allocation (often 50–70% stocks) balances growth against stability; the right choice depends on your horizon, other income, and risk tolerance.

How much should I have in stocks at 50?

A common rule of thumb is "110 minus your age" in stocks (about 60% at 50), but it's only a starting point. Over a long horizon, holding enough stocks to outpace inflation matters as much as limiting volatility.

Is 100% stocks too risky at 50?

It has the highest expected growth but the widest swings, including deep drawdowns. Whether that's "too risky" depends on your time horizon and whether guaranteed income covers your essential spending — if it does, you can tolerate more stock exposure.
