Click Calculate to see your projected pension benefits

Example: With 25 years of service, a $85,000 final salary, and a 2% multiplier, your annual pension would be $42,500 ($3,542/month). A $500,000 lump sum at 5% growth over 25 years grows to $1.69M, while $3,000/month annuity totals $900,000.

Tip: Compare the break-even point between lump sum and annuity based on your life expectancy and investment confidence.

About Pension Calculator

A pension is a retirement plan where your employer promises a specific monthly benefit based on your salary history and years of service. Defined benefit pensions calculate payments using a formula typically involving your final average salary, years of service, and a benefit multiplier. Unlike figure out your 401k projections where you bear investment risk, pension benefits are guaranteed by your employer. Many pensions offer lump sum options as alternatives to monthly payments, making the comparison calculation crucial for maximizing retirement security. Use our project Social Security income to coordinate pension income with government benefits, and explore model compound interest over time if considering a lump sum investment.

Formula

Annual Pension = Years of Service × Final Average Salary × Benefit Multiplier

For example: 25 years × $80,000 × 2% = $40,000 annual pension ($3,333/month).

Current Standards: Federal pensions use FERS (1% multiplier for most years, 1.1% after age 62 with 20+ years). State pensions vary widely, with multipliers from 1.5% to 2.5%.

Frequently Asked Questions

Should I take the lump sum or monthly annuity?

The decision depends on your life expectancy, investment ability, and need for flexibility. If you're healthy and expect to live past 85, the annuity often wins. If you have health concerns, want to leave money to heirs, or are confident investing at 6%+ returns, the lump sum may be better. Calculate your break-even age and consider whether you'd outlive it.

What is a typical pension benefit multiplier?

Multipliers range from 1% to 3% per year of service. Federal FERS uses 1% (1.1% with 20+ years retiring at 62+). State teacher and public safety pensions often use 2-2.5%. Private sector pensions typically use 1-1.5%. A 2% multiplier with 30 years of service provides 60% of your final average salary.

How is final average salary calculated?

Most pensions use your highest consecutive 3-5 years of earnings, not just your final year. Some include overtime or bonuses, while others use base salary only. Check your plan documents for the exact calculation method, as this significantly affects your benefit amount.

Can I collect pension and Social Security?

Yes, but some public pensions are affected by the Windfall Elimination Provision (WEP) or Government Pension Offset (GPO), which may reduce Social Security benefits. WEP can reduce your Social Security by up to $587/month (2026). Private pensions don't affect Social Security.

What happens to my pension if I leave before retirement?

If you're vested (typically 5-10 years), you retain the earned benefit but may not receive payments until normal retirement age. Leaving early usually means a smaller final average salary and fewer years in the calculation. Some plans offer deferred vested benefits; others may provide a reduced lump sum.
