Model the pension at several service thresholds.
Use the exact final-average compensation window, multiplier, age or service test, early-retirement factor, COLA provision, and survivor option.
ONE OFFICIAL ESTIMATE IS NOT A RETIREMENT PLAN.STATE & LOCAL EMPLOYEES · PLAN TIER / RECIPROCITY / SERVICE CREDIT
Two employees with the same salary and service can have different vesting, multipliers, COLAs, Social Security coverage, and refund rights. The member handbook—not a national pension article—must drive the model.
THE EXIT PATH CONTROLS VALUE
Do not call employee contributions the pension value. The decision is what future benefit, healthcare, COLA, and survivor rights remain under each exit path.
Use the exact final-average compensation window, multiplier, age or service test, early-retirement factor, COLA provision, and survivor option.
ONE OFFICIAL ESTIMATE IS NOT A RETIREMENT PLAN.Some systems coordinate service or salary while keeping assets separate; others do not. Get both administrators to describe the transfer or reciprocal treatment in writing.
VERIFY BOTH SIDES BEFORE THE JOB CHANGE.A refund may return employee contributions while surrendering employer-funded lifetime benefits, disability rights, retiree health, or future COLA treatment. Price the deferred benefit first.
NEVER REFUND SERVICE CREDIT TO CLEAN UP AN ACCOUNT LIST.Compare purchase cost with incremental lifetime benefit, start date, COLA, survivor continuation, refundability, funding source, and the return sacrificed elsewhere.
RUN THE INCREMENTAL BENEFIT—NOT THE TOTAL PENSION.SERVICE-PURCHASE SCREEN
Use the official purchase cost and the incremental annual pension from the same quote. This screen rejects obviously weak purchases; it does not make the final decision.
Simple cash break-even only. Taxes, COLA, survivor continuation, plan solvency, refundability, time value, funding source, and death before or after retirement can materially change the result.
THE PLAN-SPECIFIC QUESTIONS
These are the four facts most likely to make two similar employees receive very different outcomes.
Use the handbook for the exact tier and effective date. Do not borrow a formula from a coworker hired under a different statute, bargaining agreement, or plan election.
A COLA may be automatic, ad hoc, capped, delayed, or absent. Model the pension in nominal and real purchasing power using the actual provision.
The refund may omit employer-funded value and terminate service credit. Request the deferred monthly benefit and refund amount on the same date before comparing.
The 2025 law removed those reductions for benefits payable January 2024 and later. It did not award Social Security credits for non-covered employment; verify the earnings record.
OFFICIAL RULES
The calculator is a screening tool. The current plan document, administrator record, and written benefit estimate control eligibility and payment. Verify the edition and effective date before an irreversible election.
RUN THE NEXT NUMBER
Use when the plan offers a genuine lump-sum election with official amounts.
