Indiana · TRF · Benefit formula

1.1% × years × your best five years

Your TRF pension comes from three numbers. Here's each one, with the handbook's own example.

Indiana specificsShort answer: your Indiana TRF pension = final average salary (your 5 highest years) × 1.1% × years of service. The handbook's worksheet: $50,000 × 1.1% × 30 years = $16,500 a year, $1,375 a month. Open it in the calculator, then see early retirement and payment options for what changes the check. Your DC account is extra; see which plan.

The handbook's worksheet

The handbook's worksheet (Indiana TRF)
Final average salary$50,000
× 1.1% (the multiplier)$550
× 30 years of service$16,500 a year
÷ 12$1,375 a month
Hybrid Handbook p. 29, §7 Pension Benefits; p. 30, §7.4 Table 1 Pension Benefit Calculation Worksheet Example

That $1,375 is the Five-Year Certain and Life amount (Option A-1), TRF's standard way of paying. Retiring early or choosing a different option changes it. Payment options.

An unreduced pension is at least $185 a month. Hybrid Handbook p. 35, §7.11 Minimum Retirement Pension Benefit

The minimum Check with INPRS

The $185 monthly minimum is for retirees getting an unreduced pension. The handbook doesn't say how it works with survivor options.

We apply it only to unreduced pensions, on the Five-Year Certain and Life amount.

Hybrid Handbook p. 35, §7.11

1. Final average salary

Final average earnings are the highest five years of compensation in a TRF Hybrid-covered position; they need not be continuous. Included: W-2 gross compensation for covered employment, pre-tax contributions paid by your employer, amounts deferred under IRC 125/403(b)/457, pay you would have had on unpaid leave while serving in an elected position, severance paid in contemplation of retirement up to $2,000, legal settlement or back pay allocated to the year earned, and military differential wage payments on/after Jan. 1, 2009. Pay from two or more employers is combined if all required contributions were made and at least one position normally required more than 600 hours a year. Hybrid Handbook p. 31, §7.5 Final Average Earnings Calculation

Compensation is subject to the IRC 401(a)(17) annual limit, which changes yearly (see irs.gov). The handbook gives no dollar amount. Hybrid Handbook p. 13, §3.4

SEA 14-2026 changes the average annual compensation (greater of highest 5 calendar or 5 fiscal years) and excludes compensation in contemplation of retirement over 120% of the prior year, for NON-TEACHER members retiring after Dec. 31, 2027.

Which years Check with INPRS

The handbook says your average uses your highest five years of pay. It doesn't say whether those are school (July-June) years or calendar years, or how a part year counts.

We use the yearly average you enter. Your annual member statement or INPRS can confirm it.

Hybrid Handbook p. 31, §7.5

2. The multiplier

1.1% for each year, the same for everyone in TRF Hybrid. Hybrid Handbook p. 29, §7 Pension Benefits; p. 30, §7.4 Table 1 Pension Benefit Calculation Worksheet Example

3. Years of service

One year of service for 120 or more days worked in a fiscal year (July 1-June 30); a half year for 60 to 119 days. Any time worked in a day counts as a full day. No more than one year in a fiscal year. Hybrid Handbook p. 14, §4 Service Credit

Purchased service counts in the formula. Buying service credit.

Plus your DC account

The formula is the pension only. Your DC account (the old ASA) is paid on top. What's in it.
