How Illinois Teachers Retirement System Funded Ratio Compares
Plan Funded Ratio 85.4%
National avg
A ratio of 85.4% 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 Teachers Retirement System
Illinois Teachers Retirement System reports a funded ratio of 85.4% as of fiscal year 2023, earning a financial health grade of B in the Public Plans Database. The plan holds $66.50B in market assets against an unfunded liability of $11.41B. As a Teachers plan operating under Illinois sponsorship, it covers 315,573 members (166,714 active contributors, 130,051 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 above 80% signals that Illinois Teachers Retirement System has substantial assets to meet projected obligations, placing it above the national public-pension average of roughly 72–75%. Employer contributions covered 12.1% 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 $11.41B 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 Teachers Retirement System 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.
