The formula behind a defined-benefit pension

Unlike a 401(k), a defined-benefit pension pays a guaranteed monthly income set by a formula rather than by how your investments performed. The most common version multiplies years of service by a benefit multiplier by your final average salary, which is usually the average of your highest 3 or 5 earning years, not simply your last paycheck.

Formula: Annual Pension = Years of Service x Multiplier x Final Average Salary. Example: 30 years x 2% x $70,000 = $42,000 a year, or $3,500 a month.

The numbers this calculator uses

Illustrative benefit at three common multiplier levels, 30 years of service, $70,000 final average salary

2.0% per year$42,00060%
2.5% per year$52,50075%

These rows are the same formula above run at three typical multiplier levels, not figures from a specific plan or published survey. Multipliers vary by employer and job category, so use your own plan's stated rate in the calculator above rather than one of these illustrative rows.

What a pension protects you from, and what it does not

Private-sector, single-employer pensions carry federal insurance through the Pension Benefit Guaranty Corporation if the sponsoring company fails, up to a statutory limit that can fall short of a very large benefit. Most public-sector pensions, teachers, police, state employees, are not covered by that federal insurance at all and instead rely on how well-funded the plan is, a detail worth checking in your plan's annual funding report if it is publicly available.

FAQs

What counts as final average salary?

Most plans average your highest 3 or 5 years of eligible earnings, not necessarily your final year on the job, and definitions of eligible earnings can exclude bonuses or overtime depending on the plan. Check your specific plan document, since this detail alone can move the result meaningfully.

Why do multipliers differ so much between plans?

Multipliers are set by the plan sponsor and often vary by job category. Public safety and some government plans commonly use a higher multiplier than private-sector or general public-employee plans, partly reflecting different contribution rates and retirement ages. There is no single standard multiplier across all pensions.

Is a pension guaranteed no matter what happens to the employer?

Private-sector, single-employer defined-benefit pensions are generally insured up to statutory limits by the Pension Benefit Guaranty Corporation if the plan sponsor fails, though the insured amount can be lower than your full accrued benefit for very large pensions. Most state and local government pensions are not covered by that federal insurance and instead depend on how well-funded the plan itself is.

Can I take a lump sum instead of the monthly pension?

Many plans offer a lump-sum option at retirement, calculated as the present value of your expected lifetime payments using an interest rate the plan sets. Whether the lump sum or the monthly annuity is the better deal depends heavily on your health, other income sources, and how confident you are managing the investment yourself, so this is worth running past a fee-only planner before deciding.

Does a pension reduce my Social Security benefit?

It can, but only in specific situations, mainly if the pension comes from work where you did not pay Social Security payroll taxes, such as many state and local government jobs. If that applies to you, look into the Windfall Elimination Provision rules directly with the Social Security Administration rather than assuming your pension and benefit simply stack with no interaction.
