Retirement Calculator with Pension and Social Security: See How Much You’ll Need
A pension and Social Security can provide retirement income from two separate sources.
Pension payments are not counted as earnings for Social Security purposes, and Social Security benefits are based on factors including your earnings record and claiming age.
Federal income tax may apply to both sources of retirement income.

Calculate Your Retirement CostsHow the Retirement Calculator Works
The calculator adds up the money you can count on each month and compares it with what you expect to spend.
It looks at four income sources:
- Your monthly pension, with a toggle for whether it rises with inflation
- Your Social Security benefit, based on the age you plan to claim
- Withdrawals from your savings, based on the withdrawal rate you choose
- Other income, such as part-time work or rental income
Each year, your expenses grow with inflation, while your pension and Social Security grow by their cost-of-living adjustments (COLA).
The calculator then applies an estimated tax rate so you can see your after-tax income and what share of your expenses it covers.
What You’ll Need Before You Start
Having a few numbers ready makes this a five-minute exercise:
- Your Social Security estimate. Sign in to your my Social Security account at ssa.gov to see projected benefits at different claiming ages. It’s the most reliable starting point because it uses your actual earnings record.
- Your pension amount. Your plan’s benefit statement will show the monthly payment and whether it includes a COLA.
- Your savings. Add up your 401(k), IRA, and any other accounts.
- Your monthly spending. Your bank and card statements are more accurate than memory.
If you’re married, run the calculator once using your combined pensions, Social Security, and savings.
Social Security: When to Claim and What to Expect
Full retirement age
Your full retirement age is the age at which you’re entitled to your full benefit.
If you were born in 1960 or later, it’s 67. You can claim as early as 62, but your check is permanently reduced. Waiting beyond FRA increases it.
| Claim at | Approximate share of your full-retirement-age benefit |
|---|---|
| 62 | About 70% |
| 67 | 100% |
| 70 | About 124% |
Working while you collect
If you claim before full retirement age and keep working, Social Security may temporarily withhold part of your benefit.
The latest limit is $24,480 if you’re under full retirement age all year. In the year you reach full retirement age, the limit rises to $65,160, and $1 is withheld for every $3 you earn above it.
This isn’t a permanent loss. Once you reach full retirement age, your benefit is recalculated to account for the months that were withheld.
Spousal and survivor benefits
If you’re married, your decisions affect each other.
A spouse can generally claim up to half of the worker’s full-retirement-age benefit, and a surviving spouse can step up to the larger of the two checks.
Does a Pension Reduce Social Security?
No, receiving a pension does not reduce your Social Security retirement benefit.
There was an important change for certain public employees, however.
When Should You Take Social Security With a Pension?
Having a pension gives you another source of retirement income, which can affect how you think about when to claim Social Security.
You can generally begin Social Security retirement benefits at age 62, but claiming before full retirement age results in a permanently reduced monthly benefit.
If you wait beyond full retirement age, your benefit can increase through delayed retirement credits until age 70.
Before claiming Social Security while receiving a pension, consider:
- Your pension amount
- Your monthly retirement expenses
- Your health and expected retirement timeline
- Your spouse’s Social Security benefit
- Survivor benefits
- Your tax situation
- Whether you have other retirement savings
- Whether you want a larger guaranteed Social Security benefit later
If you delay Social Security beyond full retirement age, the increase stops at age 70.
