What Is a Pension?
A pension, or defined-benefit plan, guarantees a specific retirement income based on a formula — typically years of service multiplied by final average salary and a plan-specific multiplier — rather than depending on how investment contributions perform, as a 401(k) or other defined- contribution plan would. The employer (or a pension fund) bears the investment risk, not the employee.
Many pension plans also offer a one-time lump-sum buyout instead of lifetime monthly payments. Deciding between the two usually comes down to comparing the lump sum against the present value of the expected pension payments, discounted at a reasonable rate of return.

How Is a Pension Calculated?
Most defined-benefit pensions use a formula that multiplies your years of service by your final average salary (an average of your highest-earning years, typically the last 3-5) and a fixed multiplier percentage set by the plan.
Why Years of Service Matters So Much
Because years of service multiply directly into the formula, staying an extra few years — especially near the end of a career when salary (and therefore the final average) is highest — can meaningfully increase lifetime pension income, sometimes more than an equivalent amount of additional retirement savings would in a defined-contribution plan.
Lump Sum vs. Monthly Pension
Comparing a lump-sum buyout to lifetime monthly payments requires converting the future payment stream into a single present-day value using a discount rate — typically the return you could reasonably expect if you invested the lump sum yourself. A higher discount rate makes the lump sum look relatively more attractive; a lower one favors the pension.
Longevity Risk Cuts Both Ways
A lifetime pension protects against outliving your savings, since payments continue as long as you live regardless of how long that turns out to be. A lump sum shifts that risk to you — if you live longer than your life expectancy assumption, a lump sum invested conservatively could run out, while the pension would not.
Example — Your Current Inputs
After 30 years of service with a final average salary of $68,636 and a 1.5% multiplier, your estimated annual pension is $30,886 ($2,574/month) — worth about $384,913 in today's dollars over 20 years of retirement.
Additional Example — A 30-Year Career
An employee retiring after 30 years of service with a $90,000 final average salary and a 2% multiplier would receive an annual pension of $54,000 (30 × $90,000 × 2%) — $4,500 a month — for as long as they live after retirement.
About These Parameters
- Years of Service & Current/Retirement Age
- Total years of service combines years already worked with years remaining until your planned retirement age — both multiply directly into your pension formula.
- Salary & Growth Rate
- Your current salary is projected forward using the growth rate to estimate salary at retirement, then averaged over the final average salary years to approximate your plan's actual formula.
- Pension Multiplier
- Set by your specific pension plan, typically between 1% and 2.5% per year of service. Check your plan documents for the exact figure, since it varies widely by employer and plan type.
- Discount Rate & Lump-Sum Offer
- The discount rate converts future pension payments into a present-day value for comparison against a lump-sum buyout, if your plan offers one.
Frequently Asked Questions
What's the difference between a pension and a 401(k)?
A pension guarantees a specific income based on a formula, with the employer bearing investment risk. A 401(k) is a personal investment account whose final value depends entirely on contributions and market performance, with the employee bearing the risk.
Should I take the lump sum or the monthly pension?
It depends on your health, other income sources, and confidence in investment returns. Comparing the lump sum to the present value of the pension (as this calculator does) is a reasonable starting point, but factors like tax treatment and survivor benefits also matter.
Is this pension estimate guaranteed?
No — this is an estimate based on the standard final-average-salary formula. Actual pension benefits depend on your specific plan's rules, which may include early retirement penalties, cost-of-living adjustments, or survivor benefit elections not modeled here.
