CSRS Retirement Calculator

Last updated 23rd Sep 2022

This CSRS retirement calculator can help you figure out your retirement benefits under the Civil Service Retirement System. Using your age at retirement, years of service, unused sick days and High-3 salary, this CSRS calculator will provide you with an estimate of your Basic Annual Annuity, Annuity with Survivor benefits, and the Survivor Benefits themselves, if they apply. The technical description for the formula used by this CSRS calculator is the "General Formula."

Calculator Definitions

The variables used in our online calculator are defined in detail below, including how to interpret the results.

Age at Retirement (Years)

This is the age at which you expect to retire.

Years of Service (Years)

This is the number of years of service you have under the CSRS annuity system. These are typically the years of service you worked for the federal government.

Days of Unused Sick Leave (Days)

These are the total number of unused sick leave you have remaining, stated in days. This calculator uses a 261 day work year to convert the number of unused sick leave into a credit, which is applied to your years of service.

High-3 Salary ($)

This is where you would enter your High-3 salary into the calculator. Your High 3 average salary is based on the highest 3 years of base pay or salary that you earned in any consecutive 3-year period. This is normally the average of your last three years of pay.

Years of Service Credited - Sick Days (Years)

This is the number of years of service you are being credited, based on the number of unused sick leave you entered earlier.

Total Years of Credited Service (Years)

This is the total number of years of credited service this CSRS calculator will use to determine your Basic Annual Annuity.

Annuity Percentage from Years (%)

This next series of calculations shows you the annuity percentage that is derived from each "bracket" of service you have. For example, you earn 1.5% for years 1 through 5, 1.75% for years 6 through 10, and 2% for each year of credited service over 10.

Total Annuity Percentage (%)

This is the sum of all your annuity percentages calculated previously. This is the percentage that is applied to your High-3 Salary to calculate your Basic Annual Annuity benefit. By law, the Annuity Percentage is limited to 80%; however this is before any credit is applied for unused sick leave.

Annuity Reduction for Age ($ / Year)

If you retire before age 55 because of an involuntary separation, such as a reduction in workforce, then your Annuity is reduced by 2% for each year before reaching age 55.

Basic Annual Annuity ($ / Year)

This is your Basic Annual Annuity under the Civil Service Retirement System, after any adjustment for age.

Cost of Survivor Benefit ($ / Year)

If you are married, your annuity will be automatically reduced to provide the maximum survivor benefit to your spouse, which is 55% of your Basic Annual Annuity. This value is the cost of providing that benefit.

Annual Annuity with Survivor Benefit ($ / Year)

If you're married, then this is your annual annuity after being reduced to provide the maximum survivor benefit to your spouse.

Survivor Benefit ($ / Year)

This is the calculated survivor benefit that would go to your spouse, if you're married. The survivor benefit under CSRS is 55 percent of your Basic Annual Annuity.
