How Does Teacher Retirement Work? Pensions, 403(b)s, and the WEP Trap

How Do State Teacher Pensions Work?

Most state teacher pensions are defined benefit plans with a formula like: final average salary (FAS) x years of service x benefit multiplier.

Common multipliers range from 1.5% to 2.5% per year. At 2% with 30 years and a $75,000 FAS: 2% x $75,000 x 30 = $45,000/year ($3,750/month).

Vesting periods vary: some states vest at 5 years, others at 10. If you leave before vesting, you typically receive only your own contributions back (without employer contributions or interest in some states).

COLA varies dramatically: some states provide automatic 2-3% annual increases, others provide none. A pension without COLA loses 40% of purchasing power over 20 years at 3% inflation.

What Is the Windfall Elimination Provision and How Does It Affect Teachers?

In 15 states, teachers don't pay Social Security taxes. If you also worked in Social Security-covered employment (summer jobs, second career, etc.), WEP reduces your Social Security benefit.

WEP replaces the normal 90% factor on the first $1,174 of average indexed monthly earnings with a factor as low as 40%. The maximum WEP reduction is $587.50/month in 2025.

Example: A teacher with 25 years in a non-SS-covered pension and 15 years of SS-covered work might expect $1,200/month from Social Security. WEP could reduce this to $650-$800/month.

The Government Pension Offset (GPO) is even more impactful: it reduces spousal or survivor Social Security benefits by 2/3 of your government pension. If your teacher pension is $3,000/month, GPO reduces spousal SS benefits by $2,000/month — often eliminating them entirely.

How Should Teachers Use Their 403(b)?

Teacher 403(b) plans are notoriously problematic. Many are sold by insurance company agents with high-cost annuity products (2-3% annual fees plus surrender charges). Low-cost options exist but require seeking them out.

Best practices: Check if your district offers a low-cost 403(b) vendor (Fidelity, Vanguard, or TIAA with their lowest-fee options). Avoid variable annuity 403(b) products unless the plan offers no other option.

Contribution limits mirror 401(k)s: $23,500 in 2025, plus $7,500 catch-up at 50+, plus the SECURE 2.0 super catch-up at 60-63. Teachers with 15+ years of service may also qualify for the special 403(b) catch-up of $3,000/year (up to $15,000 lifetime).

A 403(b) supplements the pension and provides the tax flexibility (Roth vs. traditional) that fixed pension income lacks.
