Pension Calculator
Estimate your pension income from years of service, benefit multiplier, and final average salary.
Example
With 30 years of service, a 2% multiplier, and a final average salary of $80,000:
Annual pension = 30 × 2% × $80,000 = $48,000 per year, or $4,000.00 per month. That is a 60% replacement of final average salary.
How it works
Enter your years of service, the plan's benefit multiplier (% per year), and your final average salary. The tool multiplies them to get your annual pension and divides by 12 for the monthly amount.
Good to know
This Pension Calculator estimates the income from a defined-benefit (DB) pension using the classic formula that most government, military, teacher, and union plans use: years of service multiplied by a benefit multiplier, applied to your final average salary. It is built for anyone covered by such a plan who wants a quick, private projection of what their guaranteed lifetime payment might look like before they read the fine print of their plan document or talk to an HR or benefits office.
Reach for it when you are weighing whether to stay long enough to hit a service milestone, comparing two job offers where one carries a pension, or sanity-checking the estimate your plan administrator gave you. Because everything runs in your browser, you can plug in real salary figures without sending them anywhere. Try a few scenarios side by side, such as retiring at 25 versus 30 years of service, to see how each extra year of credited service compounds the payout.
To read the results, focus on three numbers the tool reports alongside the annual and monthly amount. The replacement rate shows what share of your final average salary the pension replaces, which is the figure most useful for retirement budgeting. The total multiplier (years times the per-year multiplier) is the fraction of salary your accrued service has earned, and the bar chart visually compares the pension against your salary so you can see the gap you may need to fill from other sources.
One important caveat: this is a gross, pre-adjustment estimate. Real plans often cap creditable years, reduce the benefit for retiring before a normal retirement age, define final average salary as the highest 3 or 5 consecutive years rather than your last paycheck, and may or may not include cost-of-living increases. The result here is a starting point, not a guaranteed figure.
Frequently asked questions
What is the benefit multiplier?
The multiplier is the percentage of your final average salary you earn for each year of service, set by your pension plan. Common values are 1.5% to 2.5% per year. For example, a 2% multiplier over 25 years gives 50% of your final average salary.
What counts as final average salary?
Most plans average your highest-earning consecutive years (often the highest 3 or 5) rather than your single last year. Use that averaged figure here for the most accurate estimate, and check your plan document for the exact definition.

People also ask
How is a defined-benefit pension calculated?
A typical defined-benefit pension equals years of service multiplied by a benefit multiplier (a percentage per year) multiplied by your final average salary. For example, 30 years at a 2% multiplier on an $80,000 final average salary produces $48,000 per year.
What is a good pension replacement rate?
Replacement rate is the percentage of pre-retirement income your pension replaces. Many retirement-planning guidelines reference a combined target of roughly 70-85% of pre-retirement income from all sources, with the pension covering only part of that and the rest coming from Social Security or savings.
Does this pension calculator include Social Security?
No. It only estimates the defined-benefit pension itself. To project total retirement income you would add any Social Security benefit and personal savings or annuity income separately.
What happens to my pension if I retire early?
Many plans apply an early-retirement reduction, lowering the monthly benefit for each year you retire before the plan's normal retirement age. This calculator does not apply that reduction, so an early-retirement estimate from it may be higher than your actual benefit.
Are pension payments adjusted for inflation?
It depends on the plan. Some pensions include a cost-of-living adjustment (COLA) that raises payments over time, while others pay a fixed amount for life. This calculator shows the starting amount only and does not model any COLA.
Is a defined-benefit pension different from a 401(k)?
Yes. A defined-benefit pension pays a formula-based amount for life and is funded and managed by the employer, while a 401(k) is a defined-contribution account whose value depends on your contributions and investment returns. This tool calculates the defined-benefit type.
Are pension benefits taxable?
In general, pension income is treated as taxable income in many jurisdictions, though specifics vary by location and by how contributions were made. The amounts shown here are gross figures before any taxes or deductions.
How many years of service do I need to qualify for a pension?
Most plans require a minimum vesting period, often around 5 to 10 years of service, before you are entitled to any benefit. The exact vesting rules and any service caps are set by your specific plan, so check its summary description.
