Pension Calculator

Estimate a future pension or retirement account value from current age, planned retirement age, salary, contribution rates, expected return, current pension value, and inflation. The calculator also estimates a monthly pension amount in today’s dollars.

How to use this calculator

Enter your current age and retirement age, then add current annual salary, expected salary increase, employee contribution percentage, employer contribution percentage, expected investment return, current pension value, and expected inflation. Results show monthly pension estimate, total pension value, today’s dollars, total contributions, employer contributions, and investment returns.

How it works

Each year, the calculator adds employee and employer contributions based on that year’s salary, applies the expected investment return, and grows salary by the salary increase assumption. At retirement, it adjusts the final value for inflation.

$monthly\ estimate = inflation\ adjusted\ value \times 0.04 \div 12$

Worked example

Suppose someone age 35 retires at 65 with 60,000 dollars in salary, 5 percent employee contributions, 3 percent employer contributions, 6 percent return, 2 percent inflation, and 10,000 dollars already saved. The projected value is about 557,602 dollars, or about 307,836 dollars in today’s dollars, producing an estimated 1,026 dollars per month.

Planning context

Run conservative and optimistic assumptions. Compare this with the retirement age calculator, social security retirement calculator, and savings goal calculator to see how different income sources fit together.
