Pension Calculator — Retirement Income
Use the Pension Calculator — Retirement Income to convert between hourly, weekly, and annual pay.
Formula
Annual Pension = Years × Multiplier × Average Salary
Multiply years of service by the pension multiplier percentage and your final average salary to get annual pension benefit.
Worked Examples
Example 1: Teacher Pension
Problem:30 years service, $70,000 final average salary, 2% multiplier.
Solution:Annual pension = 30 × 0.02 × $70,000 = $42,000 per year = $3,500 per month Replacement rate = $42,000 ÷ $70,000 = 60% With Social Security ($2,000): Total retirement income: $5,500/month
Result:$3,500/month pension
Example 2: Corporate Pension
Problem:25 years, $100,000 final salary, 1.5% multiplier.
Solution:Annual pension = 25 × 0.015 × $100,000 = $37,500 per year = $3,125 per month Replacement rate = 37.5% Need other retirement savings to reach 70-80% replacement target!
Result:$3,125/month (37.5% replacement)
Example 3: Early Retirement Impact
Problem:Eligible at 55 with 30 years service, or wait until 65. Full pension: $4,000/month.
Solution:Early at 55 (10 years early): Reduction: ~6% per year × 10 = 60% Pension: $4,000 × 40% = $1,600/month But collect 10 extra years: $192,000 At 65: Full $4,000/month Breakeven age: ~80
Result:Breakeven at ~80 years old
Frequently Asked Questions
How is a defined benefit pension calculated?
Nearly all defined benefit plans multiply three things: years of credited service, a benefit multiplier, and a salary base. Thirty years of service at a 2% multiplier produces 60% of the salary base as an annual pension for life. The salary base is usually an average of your highest consecutive earning years, though career-average plans use every year of service instead, which typically produces a smaller benefit.
What is a typical pension multiplier?
Public sector plans covering teachers, police and state employees generally use the most generous multipliers, often around 2% to 2.5% per year of service, partly because some of those workers historically did not participate in Social Security. Surviving corporate plans tend to sit nearer 1% to 1.5%. The multiplier compounds with service, so the difference between 1.5% and 2% over a thirty-year career is fifteen percentage points of salary replacement.
What is final average salary?
Final average salary is the earnings figure the multiplier is applied to, usually the average of your highest three or five consecutive years, commonly the last years worked. Plans differ on what counts: some include overtime and unused leave payouts, others use base salary only. Because the average is taken over consecutive years, a late-career promotion or a final year of heavy overtime can raise the benefit for life.
Can I collect a pension and Social Security?
Yes. Public employees were historically affected by the Windfall Elimination Provision and the Government Pension Offset, which reduced Social Security benefits for people receiving a pension from work not covered by Social Security. The Social Security Fairness Act, signed in January 2025, repealed both provisions for benefits payable after December 2023. Pensions from employment that was covered by Social Security never reduced benefits.
When should I start taking my pension?
Taking the benefit at the plan's normal retirement age gives the unreduced amount. Retiring early, often permitted up to five years sooner, reduces the monthly payment permanently, commonly by several percent for each year ahead of schedule. Some plans increase the benefit for deferring past normal retirement age, but many do not, in which case waiting simply forfeits payments. Read your plan's specific reduction factors.
What does pension vesting mean?
Vesting is the service you must complete before the accrued benefit becomes legally yours. Under ERISA, private plans generally must vest within five years under cliff vesting or seven years under graded vesting. Public plans commonly use five years. Leaving before you vest forfeits the employer-funded benefit entirely, which is why staying a few extra months can be worth a great deal near the threshold.
Is my pension guaranteed if the plan fails?
Private single-employer defined benefit plans are insured by the Pension Benefit Guaranty Corporation, a federal agency. If a plan terminates underfunded, the PBGC pays benefits up to a statutory maximum that varies with your age at retirement and is adjusted each year, so high earners can receive less than promised. Multiemployer plans have separate, lower limits. State and local government pensions are not PBGC-insured.
What is a pension COLA?
A cost-of-living adjustment raises the pension payment periodically to offset inflation. Many public plans include one, often capped at a few percent a year; most remaining private plans pay a fixed nominal amount for life. The distinction compounds enormously over a long retirement, because a level payment loses roughly half its purchasing power over twenty-four years at 3% inflation.
Should I take a lump sum or monthly payments?
A monthly annuity is longevity insurance: it cannot be outlived and requires no investment skill. A lump sum offers control, the ability to leave a balance to heirs, and protection if you doubt the sponsor's solvency, but it transfers investment and longevity risk to you. Weigh your health, your spouse's needs, how much other guaranteed income you already have, and the implied conversion rate the plan is offering.
What happens to my pension when I die?
That depends on the payout option you elect at retirement, and the choice is usually irrevocable. A single-life annuity pays the largest monthly amount but stops at your death. A joint-and-survivor option continues a percentage, commonly 50%, 75% or 100%, to your spouse for their lifetime in exchange for a smaller payment. Period-certain options guarantee payments for a set number of years regardless.
Background & Theory
Defined benefit pensions provide guaranteed monthly income in retirement based on years of service and salary.
Standard Pension Formula:
Annual Benefit = Years of Service × Multiplier × Final Average Salary
Common Multipliers:
| Sector | Typical Range |
|---|---|
| Government | 2.0-2.5% |
| Teacher | 2.0-2.3% |
| Corporate | 1.0-1.5% |
| Union | 1.5-2.0% |
Replacement Rate Target:
Financial planners suggest 70-80% of pre-retirement income:
- Pension: 40-60%
- Social Security: 20-40%
- Personal savings: fill gap
Payout Options:
| Option | Description |
|---|---|
| Single Life | Highest payment, stops at death |
| Joint & Survivor (100%) | Lower payment, spouse gets 100% after you die |
| Joint & Survivor (50%) | Medium payment, spouse gets 50% |
| Period Certain | Guaranteed minimum years |
Choosing Options:
- Married: usually joint & survivor
- Single: single life maximizes payment
- Poor health: single life or short period
- Spouse much younger: consider 100% survivor
