About the Pension Estimator

Pension Estimator is treated here as a quantitative relation between Current Age, Planned Retirement Age, Projected Total Years of Service and Final Average Salary and Annual Pension at Retirement, Monthly Pension Payment, Salary Replacement Rate and Monthly Pension at Age 80.

The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.

Formula basis:
Annual Pension = Final Salary x Years of Service x Multiplier (%)
Monthly Pension = Annual / 12
Replacement Rate = Annual Pension / Final Salary
Monthly with COLA at Age 80 = Monthly at Retirement x (1 + COLA%)^(80 - Retirement Age)

Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.

Formula & How It Works

The calculation applies the following relations exactly as recorded in the metadata:

Annual Pension = Final Salary x Years of Service x Multiplier (%)
Monthly Pension = Annual / 12
Replacement Rate = Annual Pension / Final Salary
Monthly with COLA at Age 80 = Monthly at Retirement x (1 + COLA%)^(80 - Retirement Age)

Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.

Worked Examples

Example 1: Public School Teacher — 30 Years

Inputs

current_age: 55 retirement_age: 60 years_of_service: 30 final_salary: 78000 multiplier: 2.2 cola: 2.5
Annual Pension at Retirement: $51,480. Monthly Pension Payment: $4,290. Salary Replacement Rate: 66%. Monthly Pension at Age 80: $7,030

With Current Age = 55, Planned Retirement Age = 60, Projected Total Years of Service = 30 and Final Average Salary = 78,000 as the stated inputs, the result is Annual Pension at Retirement = $51,480, Monthly Pension Payment = $4,290 and Salary Replacement Rate = 66%. Each value corresponds to the declared output fields.

Example 2: Federal Employee — FERS

Annual Pension at Retirement: $42,350. Monthly Pension Payment: $3,529. Salary Replacement Rate: 38.5%. Monthly Pension at Age 80: $5,041

With Current Age = 52, Planned Retirement Age = 62, Projected Total Years of Service = 35 and Final Average Salary = 110,000 as the stated inputs, the result is Annual Pension at Retirement = $42,350, Monthly Pension Payment = $3,529 and Salary Replacement Rate = 38.5%. Each value corresponds to the declared output fields.

Example 3: Police Officer — 25 Years

Inputs
