Pension Calculator
A defined-benefit pension guarantees a set income in retirement based on a formula — typically your final average salary multiplied by your years of service multiplied by a plan multiplier (often 1.0% to 2.0%) — and unlike a 401(k), the employer bears the investment risk, promising you a predictable monthly check for life. This calculator estimates your annual and monthly pension, the replacement rate (your pension as a percentage of your final salary), and the projected lifetime payout to age 85, so you can see the value of the benefit you're earning. Enter your final average salary, years of service, your plan's multiplier (as a percentage), and your retirement age, and the calculator returns your annual and monthly pension estimate and the replacement rate. The pension multiplier is the percentage of your salary you earn per year of service: a 1.5% multiplier with 30 years of service yields 45% of your final salary (1.5% × 30), a meaningful guaranteed income stream. Your final average salary is usually the average of your highest three to five years of earnings, though check your plan's specific definition. Vesting matters — it's the point at which you've earned a right to your pension, often after five years of service, and leaving before vesting may forfeit the benefit, so understand your plan's vesting schedule before considering a job change. Some plans offer a lump-sum option in place of monthly payments; compare the lump sum's value against the lifetime monthly payments carefully, because the lifetime value of a guaranteed income stream can be much higher than the lump sum appears. Private pensions are backed by the PBGC up to limits, and public pensions depend on their funding, so most are reliable but not entirely risk-free. Use this calculator to estimate your guaranteed retirement income, compare a pension offer against a 401(k) when choosing between jobs, and plan how your pension fits with Social Security and your own savings in your overall retirement income.
