How we estimate Nebraska School Plan pensions

Every number on the Nebraska pages comes from an NPERS publication for the Nebraska School Employees Retirement System (the NPERS School Plan), Nebraska law, a legislative report or the Nebraska Department of Revenue. Here's what the calculator does, and what it leaves out.

  1. 1

    Find your tier

    From the date you joined: Tier One before July 1, 2013, through Tier Four from July 1, 2018. You can pick a tier yourself if NPERS says yours differs (for example after repaying a refund).

    School Handbook p. 1, Benefit Tiers; School Handbook p. 1 (WARNING); p. 23, Repayment of Refund
  2. 2

    Project your service

    We add the months from today to your start date to the service you enter (or use your number as is, if you say it's your service at retirement). Start dates move to the 1st of a month.

    School Handbook pp. 21-22, Accrual Rate; School Handbook p. 35, Retirement: Effective Date
  3. 3

    Check the retirement rules

    Vested at 5 years. Full benefit at 65, or under the Rule of 85 from 55 (60 in Tier Four), using your age in years and months. Reduced from 60. The 35-year rule in state law for Tiers One to Three.

    School Handbook p. 15, Eligibility/Vesting; School Handbook p. 31, Age 65: Unreduced Normal Retirement; School Handbook pp. 32-33, Rule of 85: Unreduced Early Retirement; School Handbook p. 34, Early Retirement at Age 60: Reduced; Neb. Rev. Stat. §79-931(1)(a), (2)(a); §79-934(4); Actuarial valuation 2025 p. 65, Early retirement
  4. 4

    Apply the formula

    Years × (your yearly average ÷ 12) × 2%, rounded to the cent. That's the normal form, Option 3(a). Early retirement cuts it 3% a year (0.25% a month) under 65.

    School Handbook p. 2, Your Benefit (Defined Benefit Formula); Neb. Rev. Stat. §79-934(7)(a); School Handbook p. 43, Sample Benefit Amounts (3(a) 5-Year (Normal Form)); School Handbook p. 34, Early Retirement at Age 60: Reduced
  5. 5

    Options and the COLA

    Only the normal form is in dollars; other options use NPERS's one sample for scale. The COLA is the CPI-W capped at 2.5% (Tier One) or 1%, first paid after a full fiscal year retired.

    School Handbook pp. 43-44, Sample Benefit Amounts; Benefit Estimator; School Handbook p. 45, Cost-of-Living Adjustment (COLA)
  6. 6

    Back to work

    The 120-day separation (180 days if you left and applied before May 1, 2026), counted from the later of your last day and NPERS getting your application.

    School Handbook pp. 4, 7-8, Reemployment; table on p. 8

Each step has a plain-English guide: which tier am I?, the Rule of 85 and early retirement, the benefit formula and working after retirement. To see the steps applied to your own numbers, run the calculator.

What the calculator doesn't cover

How we check the math

The calculator runs on a small engine that reads every rule from one data file, with a source for each. Automated tests check it against the worked examples in NPERS's handbook and newsletters, and against the edges of each rule (birthdays, the Rule of 85 in each tier, age 60 and 65, the May 1, 2026 separation change). The tests run every time the site is built.

Things to check with NPERS

The sources don't settle these points. Each is labelled "Check with NPERS" where it shows up on the site.

Check with NPERS

How a partial year of early retirement is counted

NPERS's handbook counts your age in years and months for the 3%-a-year early cut, but its table and examples only show whole years, and the law says 'each year'. We don't know whether a partial year is cut by month.

What we do: We cut 0.25% for each month you are under 65 (3% a year), so 61 years 6 months is 10.5%.

What would settle it: An NPERS estimate for a member retiring at, say, 61 years and 6 months.
Check with NPERS

Retiring before 55 with 35 years

Nebraska law lets members hired before July 1, 2018 retire at any age with 35 years, but the cut before 60 is actuarial and NPERS doesn't publish the factors. The handbook doesn't mention the rule.

What we do: We tell you you may be eligible but don't estimate the amount.

What would settle it: An NPERS estimate for a member with 35 years retiring before 55.
Check with NPERS

Amounts for payment options other than the normal form

NPERS publishes only one sample table (a Tier One member at 55, 60 and 65) and says other tiers differ. Option amounts depend on your and your beneficiary's ages and, for Tiers Three and Four, on tables the board can change.

What we do: We show the 5-year period certain (normal form) amount in dollars and explain the others with NPERS's sample table. We don't estimate them.

What would settle it: NPERS's option factor tables, or a member's retirement packet estimate.
Check with NPERS

When your first COLA arrives

The handbook says the COLA starts after you've been retired 'at least one full fiscal year'. It doesn't show which July 1 that is for someone who retires partway through a fiscal year, and the statute says nothing about a wait.

What we do: Retire July 1, 2026: first COLA July 1, 2027. Retire any later month of that fiscal year: first COLA July 1, 2028.

What would settle it: NPERS confirmation, or a retiree's first COLA letter.
Check with NPERS

Birthdays on the first of the month

Your effective date is the first of the month 'following' the day you become eligible. The sources don't say what happens when you become eligible on the 1st itself (for example, a birthday on the 1st).

What we do: We read 'following' strictly: eligible on June 1 means a July 1 start.

What would settle it: NPERS confirmation or an estimate for a member born on the 1st of a month.
Check with NPERS

The 8% salary cap

Raises of more than 8% a year in your last five plan years are cut when NPERS figures your average. The calculator uses the average salary you enter, so it can't apply the cap unless you give your yearly salaries.

What we do: We use the average you enter. Our helper can apply the cap if you give yearly salaries.

What would settle it: The member's salary history for the last six plan years.
Check with NPERS

How long the 7.25% rate lasts

The 2026-27 rates (7.25% member) apply until September 1, 2027 under a 2026 law change, not June 30, 2027. NPERS's pages call them the 2026-27 fiscal-year rates.

What we do: We use 7.25% from July 1, 2026 through Aug. 31, 2027.

What would settle it: NPERS's 2027 employer rate notice.
Check with NPERS

Whether Nebraska school employees pay into Social Security

No NPERS source says outright that NPERS School Plan members pay into Social Security. State law and a legislative report point that way but don't say so directly.

What we do: We say the sources point to coverage and label it.

What would settle it: Nebraska's Section 218 agreement summary (State Social Security Administrator or SSA), or an NPERS statement.
Check with NPERS

Retiree health insurance

No NPERS source describes retiree health insurance. The handbook mentions health insurance and Medicare only as seminar topics. School districts may offer their own retiree coverage.

What we do: We say NPERS doesn't describe any retiree health benefit, and we label it.

What would settle it: An NPERS statement, or the member's school district benefits office.
Check with NPERS

Nebraska income tax on your pension

The Nebraska tax booklet lists no exclusion for school pensions (only military and federal CSRS), and NPERS says benefits are taxed by the state. We haven't seen a Revenue statement that says so directly.

What we do: We say Nebraska taxes NPERS pensions, Social Security is fully exempt since 2024, and we label the pension part.

What would settle it: Nebraska Department of Revenue guidance on public pension income.
Check with NPERS

Vesting at 65 with half a year

The age-65 half-year vesting rule is checked at your age on your retirement date, not your age when you stopped working, because the calculator doesn't ask for both.

What we do: If you joined before July 1, 2016 and were working at 65 with at least half a year, we treat you as vested.

What would settle it: The member's termination date and NPERS confirmation.
