Employees' Retirement System of Hawaii: How the pension works
Benefit formula
Benefit multiplier x average final compensation x years of credited service. Hybrid class (most general employees since 2006): 2.00% if hired before July 1, 2012, 1.75% after. Noncontributory class: 1.25%. Police and firefighters in the contributory class: 2.50% (2.25% if hired after June 30, 2012), capped at 80% of AFC
The formula above reflects the base structure. Actual benefits depend on your membership tier, bargaining unit, hire date, and whether any additional credits apply. Members hired after benefit restructuring (which happened in most states between 2008 and 2014) are often in less generous tiers than longer-tenured employees.
If you're unsure which tier you're in, your annual benefit statement from HIERS will show your projected benefit and current accrued amount. Compare those figures to the formula to back into your effective multiplier.
Covered employees
Employees' Retirement System of Hawaii covers state and county employees, including teachers, professors, police officers, firefighters, correction officers, judges and elected officials. If you're a Hawaii public employee and aren't sure whether you're in HIERS or a separate retirement system (teachers, police, fire, and judges sometimes have different plans), check your pay stub: if a pension contribution is being deducted and forwarded to HIERS, you're in this system.
Vesting and early separation
You need 10 years of creditable service to vest. Before vesting, leaving public employment generally gets you back only your own employee contributions, if your plan required any. Once vested, you're entitled to a future pension benefit even if you leave before reaching retirement age, though you may need to wait until a specific age to start receiving payments.
Leaving before vesting and taking the contribution refund is usually a mistake unless you have a specific cash need. That money grew tax-deferred, and forfeiting the pension benefit means you gave up the employer-funded portion entirely. If you're close to the vesting date, staying is almost always worth it.
Lump sum option
The ERS pays a monthly pension with no lump sum option. Hybrid members hired after June 30, 2012 contribute 8% of pay, vest at 10 years and get full benefits at 65 with 10 years or 60 with 30. Those hired earlier contribute 6%, vest at 5 years and get full benefits at 62 with 5 or 55 with 30. Early retirement costs 5% a year under 65 for Hybrid members hired after mid-2012, 5% a year under 62 for earlier Hybrid members, 6% a year under 62 for Noncontributory members, and 5% a year under 55 plus 4% a year under 50 for Contributory members. Noncontributory members pay nothing toward the pension, so there are no member contributions to refund, and they vest at 10 years.
Since HIERS doesn't pay a lump sum, the choices that move your numbers are when you retire and which survivor option you pick. The calculator below puts a present value on your estimated monthly benefit, in today's dollars.
What the present value calculation tells you
HIERS won't pay this amount out, but the present value still does three jobs. It lets you compare the pension with alternatives, such as leaving for a private-sector job with a 401(k). It shows what a refund of contributions would cost you once you're vested. And it puts a number on the retirement income you've built, which feeds Social Security timing and IRA drawdown decisions.
The IRS 417(e) formula uses three segment rates to discount future pension payments back to today. At current rates (4.07%, 5.15%, 6.01% for 2026), a $2,500/month pension starting at 65 is worth about $369,000 as a single sum under the IRS 2026 mortality table. Public plans don't have to offer that amount, and most don't offer a lump sum at all.
Coordinating your HIERS pension with Social Security
Social Security coverage depends on the position. Some state and local government jobs are outside Social Security, and those jobs don't earn Social Security benefits. Check your pay stub: if no Social Security (OASDI) tax is withheld, that job probably isn't covered. Medicare tax on its own doesn't mean the job is covered.
If you have private-sector work history where you did pay into Social Security, the Windfall Elimination Provision (WEP) and Government Pension Offset (GPO) previously reduced Social Security benefits for workers with government pensions. Both were repealed by the Social Security Fairness Act of 2023, signed January 5, 2025, effective for benefits payable after December 2023. SSA finished paying the retroactive amounts in 2025. If you think yours is missing, contact SSA.
If your public employment included Social Security contributions, which varies by state and by position, then Social Security timing still matters, and the break-even analysis is worth running separately. The Social Security break-even calculator on this site handles that calculation.

Frequently asked questions
How is an HIERS pension calculated?
Employees' Retirement System of Hawaii uses this formula: Benefit multiplier x average final compensation x years of credited service. Hybrid class (most general employees since 2006): 2.00% if hired before July 1, 2012, 1.75% after. Noncontributory class: 1.25%. Police and firefighters in the contributory class: 2.50% (2.25% if hired after June 30, 2012), capped at 80% of AFC. The average HIERS retiree receives about $2,804 per month, though amounts vary widely based on salary and years of service.
How many years do I need to vest in HIERS?
You need 10 years of creditable service to vest in Employees' Retirement System of Hawaii. Before that point, leaving means you're entitled only to your own contributions back, with no pension benefit.
Does HIERS offer a lump sum?
The ERS pays a monthly pension with no lump sum option. Hybrid members hired after June 30, 2012 contribute 8% of pay, vest at 10 years and get full benefits at 65 with 10 years or 60 with 30. Those hired earlier contribute 6%, vest at 5 years and get full benefits at 62 with 5 or 55 with 30. Early retirement costs 5% a year under 65 for Hybrid members hired after mid-2012, 5% a year under 62 for earlier Hybrid members, 6% a year under 62 for Noncontributory members, and 5% a year under 55 plus 4% a year under 50 for Contributory members. Noncontributory members pay nothing toward the pension, so there are no member contributions to refund, and they vest at 10 years.
Can I withdraw my HIERS contributions if I leave?
Before vesting, you can typically withdraw your employee contributions if you separate from Hawaii public employment. This forfeits any future pension benefit. After vesting, you can still withdraw contributions in some plans, but doing so usually means giving up the pension rights you've earned.
Where can I find my HIERS benefit estimate?
Log in to the member portal at ers.ehawaii.gov. Most systems offer online calculators and annual statements showing your current accrued benefit and projections at various retirement ages. You can also call HIERS directly for a personalized benefit estimate.
