How Illinois Municipal Retirement Fund Funded Ratio Compares
Plan Funded Ratio 63.0%
National avg
A ratio of 63.0% compared against the national public-pension average of 73.5%.
Healthy Threshold
Plans above 80% are generally considered adequately funded by NASRA standards.
Participant Composition
The active-to-retiree ratio is a leading indicator of long-term plan sustainability — plans with more retirees than active contributors face mounting cash-flow pressure as benefit payments outpace incoming contributions.
Investment Policy Mix
Public pension plans report their asset allocation in Form 5500 Schedule H Part I disclosures. Equity-heavy mixes capture market upside but introduce volatility; fixed-income tilts protect funded status during downturns at the cost of long-run return.

What the Data Says About Illinois Municipal Retirement Fund
Illinois Municipal Retirement Fund reports a funded ratio of 63.0% as of fiscal year 2023, earning a financial health grade of C in the Public Plans Database. The plan holds $52.63B in market assets against an unfunded liability of $30.93B. As a Municipal plan operating under Illinois sponsorship, it covers 519,512 members (181,357 active contributors, 153,479 retirees drawing benefits). These figures aggregate from Form 5500 filings submitted to the Department of Labor and actuarial valuations reported through NASRA.
A funded ratio in the 60–80% range indicates moderate underfunding that falls near the national average of 72–75% but leaves the plan exposed to market downturns and demographic shifts. Employer contributions covered 28.4% of the Annual Required Contribution in the most recent reporting cycle, while the plan posted a 5-year average investment return of 8.1%. The relationship between contribution adequacy and investment performance determines whether the unfunded liability narrows or expands year over year.
For Illinois taxpayers and plan members, the $30.93B unfunded gap represents the actuarial shortfall that must eventually be closed through a combination of contributions, investment returns, or benefit modifications. Unlike private-sector pensions governed by ERISA and backstopped by the PBGC, public plans like Illinois Municipal Retirement Fund rely on the full faith and credit of Illinois — meaning funding shortfalls flow through to state and local budgets rather than a federal insurance program.
