Pension Calculator

Calculate your estimated pension benefits based on years of service, salary, and pension multiplier. Plan your retirement income.

About this calculator

This models a defined-benefit pension, the traditional formula-based plan that still covers most public-sector employees (teachers, police, firefighters, many state and federal workers) even though it's largely vanished from private-sector employment. The core formula multiplies three numbers: Years of Service, Pension Multiplier (the accrual rate per year, commonly 1.5-2.5% depending on the plan), and Final Average Salary (the average of your highest-earning years, typically the last three to five, rather than your current pay). Annual Pension is that product; Monthly Pension just divides by 12.

Income Replacement Ratio compares Annual Pension against Final Average Salary to show what share of pre-retirement income the pension alone replaces -- most retirement-planning guidance targets 70-80% total replacement across all income sources combined, not from a pension alone. Estimated Total Pension Value multiplies Annual Pension by years from Retirement Age to age 85, a single illustrative life-expectancy assumption built into the formula, not a personalized actuarial projection -- someone who lives longer collects more than this figure shows, and someone who doesn't collects less. Every real pension plan sets its own multiplier, averaging period, and vesting rules in its plan document; treat this as a generic formula shape to sanity-check a statement against, not a substitute for your plan's actual benefit calculation.

How to Use This Calculator
  1. Enter your current age and target retirement age.
  2. Input your current annual salary.
  3. Enter your years of service — this is typically the key multiplier in pension formulas.
  4. Set the pension multiplier (commonly 1.5-2.5% per year of service).
  5. Review the final average salary used, annual pension, monthly pension, income replacement ratio, and estimated total pension value.

Frequently Asked Questions

Why doesn't Current Annual Salary affect Annual Pension?

The formula uses Final Average Salary -- the average of your highest- earning years, typically the last three to five before retirement -- not your salary today. If you expect meaningful raises before retiring, Final Average Salary will run higher than Current Annual Salary, so entering today's salary in that field would understate the benefit; the calculator defaults Final Average Salary to your Current Annual Salary only as a starting point you should adjust.

What's a typical Pension Multiplier?

Most defined-benefit plans use somewhere between 1.5% and 2.5% per year of service, though the exact figure is set entirely by each plan and varies by employer, job class, and sometimes by years of service tier. A teacher's pension plan, a police and fire plan, and a federal employee plan can all use different multipliers even within the same state, so check your plan's official summary rather than assuming a typical figure applies to you.

Why does Retirement Age affect Estimated Total Pension Value even though it doesn't affect Annual Pension?

Estimated Total Pension Value multiplies Annual Pension by an assumed number of years in retirement, calculated here as age 85 minus Retirement Age. A later Retirement Age shortens that assumed collection period even though it leaves the annual benefit itself unchanged, so Estimated Total Pension Value can fall even as Years Until Retirement falls too -- fewer assumed years of collecting the same annual amount.

Is the age-85 assumption behind Estimated Total Pension Value realistic for me personally?

It's a single round-number illustration, not a personalized life-expectancy estimate. Actual life expectancy varies by individual health, family history, and demographic factors that this calculator has no way to account for, so someone who lives past 85 collects substantially more in total pension payments than this figure shows, and this number should be treated as a rough planning anchor, not a forecast.
