Understanding Public Pensions in the USA
Defined benefit (DB) plans like TRS, CalSTRS, NYSTRS, and FERS guarantee a lifetime monthly pension based on a formula (years × multiplier × salary). The employer bears the investment risk.
Defined contribution (DC) plans like 401(k), 403(b), and TSP are individual investment accounts. The employee bears all investment risk, but portability is higher and the account can be inherited.
Many public employees have both: a DB pension plus a supplemental DC account (e.g., FERS + TSP, or TRS + 403(b)).
Financial planners typically recommend replacing 70–85% of pre-retirement income to maintain the same standard of living. Public pensions often provide 50–75% replacement for long-career employees.
The gap is usually filled by Social Security (for those eligible) and personal savings (403(b), 401(k), IRA, TSP). Teachers in some states (like Texas, Ohio, Louisiana) do not participate in Social Security for their teaching jobs and must save more aggressively.
Use the calculators above to estimate each leg of your three-legged retirement stool.
If you worked in a job where you did not pay Social Security taxes (e.g., teaching in Texas TRS, Ohio STRS, or Louisiana TRSL), and you also qualify for Social Security from another job:
Windfall Elimination Provision (WEP) can reduce your own Social Security benefit by up to ~$558/month (2025).
Government Pension Offset (GPO) can reduce spousal/survivor Social Security benefits by 2/3 of your public pension amount.
Note: H.R. 82 (Social Security Fairness Act) repealed WEP and GPO in January 2025, but implementation is ongoing. Check with SSA for current status.
Each of the 50 states runs its own teacher and public employee retirement systems. Formulas, multipliers, contribution rates, and COLA provisions vary widely:
- Highest multipliers: Massachusetts (MSERS 2.5%), Pennsylvania (PSERS 2.5% Class T-E)
- Lowest multipliers: Florida FRS (1.6%), Tennessee (1.5%), Mississippi PERS (1.55%)
- Best COLAs: CalPERS (up to 2%), Maine PERS (CPI-based)
- No COLAs: Texas TRS, NYSTRS, Florida FRS (post-2011), Ohio STRS — all ad-hoc or none
- Non-Social Security states (for teachers): TX, OH, LA, MA, IL (Chicago), NV, AK, ME, CO, KY, CA (some districts)
This calculator now includes 8 pension systems covering teachers and federal employees across CA, NY, PA, OH, MA, FL, TX, and the federal government — plus Social Security, 403(b)/401(k) savings, a side-by-side comparison tool, and a combined retirement income aggregator. More state systems (Georgia TRS, Illinois TRS, Kentucky KERS, North Carolina TSERS) will be added in future updates.
This website provides estimates only for educational and planning purposes. Calculations use publicly available 2025 plan documents, simplified formulas, and current-year parameters. Actual benefits may differ due to:
- Tier-specific rules and legacy plan provisions
- Purchase of service credit, military service, or out-of-state reciprocity
- Survivor and joint-and-survivor annuity options
- Salary caps, contribution limits, and tax treatment
- Future legislative changes to plan formulas
- Individual circumstances like disability retirement or early separation
Always request an official benefit estimate from your retirement system before making career or financial decisions. Consult a fee-only financial advisor for personalized advice.

Retirement Planning Case Studies
Real-world scenarios showing how the calculators on this site apply to actual retirement planning situations. Each case study includes inputs, calculations, results, and key takeaways you can apply to your own situation.
30 years of TRS service at age 55 (meets Rule of 80). Wants to know her pension and how much supplemental savings she needs.
30 × 2.3% × $72,000 = $49,680/year pension (no age reduction because Rule of 80 met). Plus 403(b) at 7% growth over 25 years to age 80: $85,000 grows to ~$461,000; 4% withdrawal = $18,440/year.
Total retirement income: ~$68,120/year ($49,680 pension + $18,440 403(b)). Replacement rate: 94% of $72,000 final salary. Since Texas teachers don't get Social Security for teaching, this 94% replaces what would otherwise be a 3-stream retirement.
Maria's aggressive 403(b) saving (started at age 25) and Rule of 80 eligibility give her a comfortable retirement despite no Social Security. The 403(b) is critical — without it, her pension alone would replace only 69% of salary, with no inflation protection (TRS has no automatic COLA).
30 years of federal service at MRA (57). Trying to decide between retiring now (MRA+30, unreduced) vs. working to 62 for the 1.1% multiplier.
At age 57 (MRA+30, unreduced): 30 × 1.0% × $118,000 = $35,400/year. At age 62 (1.1% multiplier): 35 × 1.1% × $130,000 (estimated High-3 with raises) = $50,050/year. TSP at 7% growth to age 62: $420,000 grows to ~$589,000; 4% withdrawal = $23,560/year. Plus Social Security at 62: ~$22,000/year (reduced for early claiming).
At 57: $35,400/yr pension + ~$0 SS (not yet eligible) + ~$14,000 TSP withdrawal = $49,400/yr (42% replacement). At 62: $50,050/yr pension + $22,000 SS + $23,560 TSP = $95,610/yr (74% replacement of estimated $130k final salary).
Working 5 more years nearly doubles James's retirement income. The combination of the 1.1% multiplier, additional service years, higher High-3, full TSP growth, and Social Security eligibility makes age 62 retirement dramatically more lucrative. MRA+30 is unreduced but doesn't include the 1.1% bonus or Social Security.
Has $5,000 to invest. Currently in 22% federal bracket; expects to be in 24% bracket in retirement due to CalSTRS pension filling lower brackets.
Roth: contribute $5,000 × (1 - 0.22) = $3,900/yr post-tax. Future value at 7% over 30 years: $3,900 × 94.46 = $368,400. All tax-free. Traditional: contribute $5,000/yr pre-tax. Future value: $5,000 × 94.46 = $472,300. After 24% retirement tax: $472,300 × 0.76 = $358,948.
Roth wins by $9,452 in after-tax wealth. The reason: Priya expects a higher retirement bracket (24% vs. 22% now), so paying tax now at 22% is cheaper than paying 24% later. Plus Roth has no RMDs and passes tax-free to heirs.
For younger workers expecting higher future earnings (or significant pension income in retirement that fills lower brackets), Roth almost always wins. Priya's CalSTRS pension will provide $40k+ in retirement income, pushing her into the 24% bracket even without other withdrawals. Use our Roth vs Traditional calculator to model your own situation.
Both eligible for Social Security. Robert has higher PIA and better health history. Want to maximize lifetime household benefits and protect the survivor.
Strategy A (both claim at 62): Robert $1,960/mo, Susan $980/mo = $2,940/mo household. Reduces to $1,960/mo survivor benefit when Robert dies. Strategy B (Robert delays to 70, Susan claims at 67): Robert $3,472/mo (124% PIA), Susan $1,400/mo = $4,872/mo household. Survivor gets $3,472/mo after Robert's death.
Strategy B provides $1,932/mo more household income ($23,184/year) while both are alive, AND $1,512/mo more for Susan as a widow. Over Susan's expected lifetime to age 92 (assuming Robert dies at 82), Strategy B pays roughly $400,000 more in total benefits, even accounting for the 8 years of foregone Robert benefits (ages 62-70).
When one spouse has a significantly higher PIA and longer life expectancy, delaying that spouse's claim to age 70 is almost always optimal. The survivor benefit is locked in at the higher earner's delayed amount. This is one of the most valuable but underutilized Social Security strategies.

About These Calculators
The Retirement and Pension Calculator is a free, independent web tool built to help U.S. public-sector workers, teachers, federal employees, and anyone planning for retirement understand their pension, Social Security, and personal savings options. The site is not affiliated with any government agency, retirement system, or financial institution — it is an educational resource run by people who care about retirement literacy.
Our methodology: Each calculator on this site is based on the official 2025 plan documents published by the relevant retirement system (TRS Texas, CalSTRS, NYSTRS, PSERS, STRS Ohio, MSERS, FRS, OPM/FERS, SSA, and IRS). We update the formulas, contribution limits, income phase-outs, and bend points annually as the IRS and SSA release new figures. However, every calculator uses simplified formulas that may not capture every edge case — tier-specific provisions, purchased service credit, disability retirement, survivor benefit elections, and individual salary histories all affect actual benefits in ways no calculator can fully predict.
Why our estimates may differ from official statements: The most common reasons are: (1) we use a simplified Final Average Salary rather than your actual salary history; (2) we don't model purchased service credit or reciprocity agreements; (3) we use a single retirement age rather than month-by-month calculations; (4) we don't account for early retirement incentives or special plan provisions; (5) we don't model tax implications of withdrawal strategies. Our estimates are typically within 5–15% of official calculations, but can be off by more in edge cases.
What you should do: Use these calculators for planning, "what-if" scenarios, and understanding the rough magnitude of your retirement income. When you are within 5 years of retirement, request an official estimate from your retirement system(s) — most systems provide this for free through an online portal or by mail. For personalized advice, hire a fee-only financial advisor who is a fiduciary (legally obligated to act in your best interest) and who has experience with public-sector retirement systems.
