Am I Safe to Retire?

This is the question underneath all the others — and it deserves a straight answer up front.

No tool — and no adviser — can promise you’ll be fine. The true answer only arrives after you’ve lived it: no one knows in advance how markets, inflation, or your own life will actually unfold. That’s exactly why the goal is to weigh your options and risks — not to chase a guarantee no one can give. What RetireRange can do is give you a well-grounded read on the odds — how your plan holds up across thousands of possible futures and the worst of real market history — so you can decide with clarity and confidence instead of a gut feeling. That’s not certainty. It’s the next best thing: knowing the range of what’s likely, and how much margin you have.

Think of it as comfort in the odds, not a crystal ball. RetireRange replaces "I hope so" with "here’s where my plan stands, and here’s what would have to go wrong."

The quick version

1. Run your plan and look at your success rate — your odds, not a verdict.
2. Check the downside — shortfall, the worst-luck (P10) outcomes, and how early trouble would start.
3. Stress-test it against bad markets and pessimistic assumptions.
4. Decide whether the odds — and the margin — give you comfort.

Reading your "am I safe?" answer

Success Rate — your odds. A 90% success rate means your plan survived in 9 of 10 simulated futures. It’s a measure of resilience, not a guarantee — and higher isn’t automatically better. Most people find comfort somewhere in the 85–95% range; chasing 100% often just means you’re under-living and leaving money unspent. (More on reading results.)

The downside is where "safe" really lives. Don’t stop at the median:

• Shortfall Rate — how often you’d have to cut spending, even briefly.
• P10 (worst-luck) trajectory and the ruin-probability chart — if the unlucky cases still hold up, you’re robust; if they collapse, you’re exposed even when the average looks fine.

Stress-test it. A plan that only works in good markets isn’t really safe. Turn on the bad-sequence overlay, run the Historical backtest, and try pessimistic returns. If your plan survives 1929, 1966, and 2000, that’s meaningful reassurance.

If the odds don’t give you comfort

"Not yet" is useful information, and it’s rarely all-or-nothing. Each of these improves your odds — make the change and re-run:

• Delay retirement a year or two — often the single biggest lift.
• Trim or phase spending, or switch to a Guardrails method so spending flexes in bad markets.
• Delay Social Security to raise your guaranteed, market-proof income.
• Hold a larger cash reserve to ride out downturns without selling low — set it under Strategy → Cash Reserve Target, and turn on recovery refill so it restocks in good years (how it works).

The bottom line

Being "safe to retire" isn’t a switch that flips — it’s a probability you can understand, improve, and keep watching. And the decision isn’t one-and-done: you can reconcile your balances and re-run every year, adjusting as real life unfolds. RetireRange won’t tell you the future — nothing can — but it will let you walk into retirement knowing your real odds, where your plan is fragile, and that you’ve arranged the best chances you reasonably can. For many people, that clarity is the confidence they were looking for.
