Understanding Pension Funded Ratios
The most important number in pension finance — what it means, how to read it, and what it tells you about the security of your retirement benefits.
The funded ratio is the single most important indicator of pension health, but it must be read alongside the trend direction and ARC payment rate. A plan at 70% and improving is in a fundamentally different position than a plan at 80% and declining. Both the level and the trajectory matter.
What a Funded Ratio Tells You
The funded ratio is deceptively simple: plan assets divided by plan liabilities, expressed as a percentage. If a plan has $8 billion in assets and $10 billion in liabilities, its funded ratio is 80%. This means it has 80 cents available for every dollar of promised benefits.
But this simplicity masks important nuances. The denominator — liabilities — is a present value calculation that depends heavily on actuarial assumptions, particularly the discount rate (the assumed investment return). A plan using a 7.5% discount rate will show a higher funded ratio than the same plan using 6.0%, because future liabilities are discounted more aggressively. This is why direct comparison between plans requires understanding their assumptions.
The Funded Ratio Spectrum
100%+ (Fully Funded): The plan has sufficient assets to cover all promised benefits under current assumptions. Few public plans achieve this consistently. Those that do typically have strong contribution discipline and favorable demographics.
80-99% (Adequately Funded): The plan has a manageable gap that can be closed with sustained contributions and reasonable investment returns. Most pension experts consider 80% a threshold of adequate health, though the trend matters more than the precise number.
60-79% (Underfunded): The plan has a significant gap. Benefits are still being paid, but the risk of contribution increases, benefit modifications for new employees, or COLA suspensions is elevated. Plans in this range need active remediation. Check your plan's health grade on our plan pages.
Below 60% (Critically Underfunded): The plan is in serious financial distress. Without dramatic intervention — major contribution increases, benefit reforms, or both — the gap will continue to widen. Plans at this level face the highest risk of benefit reductions. See our worst-funded rankings.
Why Trend Matters More Than Level
A plan at 75% funded ratio that has improved from 65% over five years is on a healthier trajectory than a plan at 85% that has declined from 95%. The trend tells you whether the remediation efforts are working — whether contributions are adequate, investments are performing, and the gap is closing rather than widening.
PlainPension shows historical funded ratio data going back to 2001, enabling you to see how your plan performed through the 2008 financial crisis, the recovery, and subsequent market cycles. Plans that maintained or improved their funded ratios through these periods demonstrated resilient governance and disciplined funding.
When examining trends, pay attention to the rate of change, not just the direction. A plan improving from 60% to 65% over five years is making progress, but at that pace it would take decades to reach full funding. A plan improving from 60% to 75% over the same period — typically through a combination of increased contributions and favorable investment returns — is on a much faster path to financial health.
The ARC Payment Connection
The Actuarially Required Contribution (ARC) is the annual payment governments must make to keep the plan on track to full funding. When governments pay less than the full ARC — which is common during budget crises — the unfunded liability grows, and the funded ratio declines. Sustained ARC underpayment is the single largest driver of pension underfunding.
When you look up a plan on PlainPension, check both the funded ratio and the ARC payment rate. A plan where the government consistently pays 100%+ of the ARC is on a path to improvement. A plan where ARC payments are 80% or less is likely to see its funded ratio continue declining.
What This Means for You: A Practical Framework
Step 1 — Look up your plan on PlainPension. Check the funded ratio, health grade, and ARC payment rate on our plan pages.
Step 2 — Check the trend. Is the funded ratio improving, stable, or declining over the past 5-10 years? Trend direction matters more than the current level.
Step 3 — Understand the assumptions. What discount rate does your plan use? A plan showing 80% at a 7.5% discount rate is less conservatively funded than one showing 80% at 6.5%.
Step 4 — Plan accordingly. If your plan is well-funded with strong ARC payments, your pension benefit is likely secure. If your plan is critically underfunded, consider supplemental retirement savings to reduce your dependence on the pension alone.
Beyond the Funded Ratio: What Else to Watch
While the funded ratio is the headline metric, two additional factors deserve attention. First, the plan's investment allocation and performance relative to its assumed return rate. Plans that consistently miss their return assumptions will see funded ratios decline even with full ARC payments.
Second, the demographic profile — the ratio of active contributing members to retirees drawing benefits. Plans with aging membership and declining active member counts face structural pressure regardless of funded ratio. When a plan has more retirees than active workers, it becomes increasingly dependent on investment returns rather than contributions to fund benefits.
PlainPension shows these metrics alongside the funded ratio to give you the complete picture of your plan's financial trajectory. Examining all three dimensions — funded ratio, contribution discipline, and demographic profile — together provides a much more reliable assessment than any single metric alone.
Frequently Asked Questions
What is a pension funded ratio?
A funded ratio expresses plan assets as a percentage of plan liabilities. An 80% funded ratio means the plan has $0.80 in assets for every $1.00 of promised benefits. A ratio of 100% means fully funded. The funded ratio is the single most important indicator of pension financial health.
What is a good funded ratio for a pension plan?
Generally, 80% or above is considered adequately funded, though 100% is the ideal target. Plans below 60% are considered critically underfunded. However, a plan at 75% with a rising trend and full ARC payments may be healthier than a plan at 85% with declining ratios and ARC underpayment.
Why do some pensions have funded ratios below 50%?
Severe underfunding results from decades of contribution shortfalls, investment losses, benefit enhancements made without funding, and demographic changes. Plans in states like Illinois, New Jersey, and Kentucky have funded ratios below 50% due to chronic government underpayment of required contributions.
Can a pension still pay benefits if it is not fully funded?
Yes. Plans pay benefits from a combination of investment returns, employer contributions, and employee contributions — not just from existing assets. A plan at 70% funded can continue paying benefits indefinitely if contributions are adequate and investment returns meet assumptions. The risk is that benefits may need to be reduced if the gap widens.

A worked example
Consider a household earning $75,000 per year facing an annual cost of $18,000 for the service this guide covers. Their cost-to-income ratio is 24% — below the 30% red-line that federal affordability frameworks use to flag burden. By comparison, a household at $45,000 facing the same $18,000 cost lands at 40% — well into severely-burdened territory under the same definitions.
Where to dig deeper
The methodology page documents exactly which federal series we draw from, how we weight regional differences, and the reference period for each metric. The research section publishes original analyses derived from the same underlying database — useful when you want to see year-over-year shifts or peer-jurisdiction comparisons that the per-page detail views don't surface.
| Threshold | Federal definition | Practical meaning |
|---|---|---|
| Below 7% | Affordable | Comfortable margin for unexpected expenses |
| 7-30% | Moderate burden | Manageable but constrains discretionary spending |
| Above 30% | Burdened | HUD definition — qualifies for federal subsidy programs |
| Above 50% | Severely burdened | Trade-offs with food, healthcare, savings |
