About the Public Employee Retirement System of Idaho (PERSI)
The Public Employee Retirement System of Idaho (PERSI) is Idaho's primary retirement plan for public school teachers. It is a <strong>defined benefit</strong> plan, meaning your retirement income is guaranteed by formula — not dependent on market performance.
Your monthly pension is calculated as: Years of Service × 2.0% × Final Average Salary (averaged over your highest 4 years). For example, a teacher with 30 years of service and a $70,000 final average salary would receive approximately $3,500/month before any deductions.
Vesting: You must complete 5 years of service to vest. Before that point, leaving the system means forfeiting your pension benefit entirely (though you can withdraw your own contributions).
Cost-of-living adjustments (COLA): The Public Employee Retirement System of Idaho (PERSI) does not currently provide automatic COLA increases. Your pension will remain fixed in nominal terms, which means inflation reduces its real value over time. Planning for supplemental savings (403b, Roth IRA) is especially important in Idaho.
Employee contribution rate: Idaho teachers contribute 7.2% of their salary to the pension system each year.
