Your Plan Health Check

By Horizons Editorial Team

Educational information, not individual financial advice.

Key Takeaways

A healthy plan has an emergency fund, a sustainable withdrawal rate, manageable debt, no single oversized position, and a solid savings rate
The common benchmarks — 3–6 months' expenses, ~4% withdrawals, 28/36 housing/debt, ~15% savings — are guidelines to aim for, not pass/fail tests
Treat each flag as an actionable nudge, then decide what fits your situation

A plan health check runs a short checklist over your finances and flags the spots most likely to cause trouble. None of the thresholds is a law — they're well-worn rules of thumb. The value is in turning a vague worry into a specific, actionable nudge.

The checks that matter most

Emergency fund — 3 to 6 months of essential expenses. Enough cash to ride out a job loss or surprise bill without selling investments or reaching for a credit card. The right number depends on how stable your income is.

Withdrawal rate — around 4% at retirement. Planning to spend much more than ~4% of your investable assets in the first year of retirement is a readiness flag (the Bengen/Trinity research). It's a starting guide, not a guarantee.

Housing and debt — the 28/36 rule. Housing costs under ~28% of gross income, total debt payments under ~36%. Above those levels, the budget gets fragile when anything goes wrong.

Concentration — no single position above ~5–10%. One holding (often employer stock) dominating your net worth couples your savings to your paycheck and one company's fate. Regulators frame concentration qualitatively, so treat the percentage as a prompt to think, not a hard line.

Savings rate — around 15% of gross income toward retirement, including any employer match. Small changes here compound into large differences in your retirement date.

Guidelines, not verdicts

Every one of these is a convention, not a regulator's standard. A 5-month emergency fund isn't a "fail," and one year above 4% won't sink a flexible retiree. Read the flags as a prioritized to-do list: which gap, if you closed it, would most improve your resilience?

How Horizons uses this

Horizons reviews your plan against these benchmarks and surfaces the flags — thin emergency fund, unsafe withdrawal rate, over-concentration, high-interest debt — each linked to where you can act on it.
