Social Security Calculator

What is a Social Security benefits calculator?

A Social Security benefits calculator estimates your retirement benefit based on your earnings and the age you claim. This Social Security retirement calculator shows an estimated monthly benefit at each claiming age from 62 to 70.

The estimate starts with your average indexed monthly earnings, or AIME. That figure reflects your average earnings after they are adjusted for changes in wage levels over time. The calculator uses your average indexed yearly earnings to estimate it. It then applies the Social Security benefit formula to calculate your primary insurance amount, or PIA. Your PIA is the benefit at your full retirement age, before any adjustment for claiming earlier or later.

Why your Social Security estimate matters

Your claiming age changes your monthly benefit. Claiming before full retirement age reduces the PIA. Waiting past full retirement age increases it. Seeing estimates at different ages can help you compare a larger check later with income you may need sooner.

Use the estimate as one part of your retirement budget. Compare it with expected expenses, savings withdrawals, pension income, and any pay you expect to earn. The result can help you decide whether to keep working, draw less from savings, or adjust your planned retirement date.

This calculator uses the 2026 bend points. It is an estimate, not an official Social Security determination. Your earnings record and future changes to Social Security rules can affect your actual benefit. If you work while claiming, check the Social Security Administration’s earnings-test rules and current exempt amounts. For a retirement claiming decision, confirm your estimate with Social Security or a qualified financial professional.

How to use this Social Security calculator

1. Enter your birth year. The calculator uses it to determine your full retirement age. For people born in 1960 or later, full retirement age is 67.
2. Choose whether to start from average yearly earnings or another available earnings method. Use earnings that reflect your work history, not just your current salary.
3. Enter your average indexed yearly earnings if you selected that method. If you are unsure of the figure, check your Social Security earnings record and use the calculator’s available earnings options.
4. Enter the age you plan to claim. Review the result for that age, then compare it with the estimates for other claiming ages from 62 to 70.

How to read your Social Security calculator results

The primary insurance amount is your estimated benefit at full retirement age. The claiming age is the age used for the estimate. The adjustment shows how claiming before or after full retirement age changes the benefit. The monthly and yearly benefit figures are estimates based on the inputs you provided.

The 2026 formula applies 90% to the first $1,286 of average indexed monthly earnings, 32% to earnings above $1,286 and up to $7,749, and 15% to earnings above $7,749. Claiming early reduces the benefit by 5/9 of 1% a month for 36 months, then 5/12 of 1% a month for additional months. Delaying past full retirement age adds 2/3 of 1% a month.

How to make your Social Security estimate more useful

1. 01

   Check your earnings record

   Review the earnings history used for your estimate. If you spot missing or incorrect wages, contact Social Security to ask how to correct the record. An accurate history gives you a more useful estimate.

2. 02

   Compare more than one claiming age

   Look at the monthly estimates across the available ages. Consider how each amount fits your expected expenses, savings, and plans to keep working. Do not base the decision on the largest monthly figure alone.

3. 03

   Test different earnings assumptions

   If the calculator allows you to enter different earnings amounts, compare estimates using figures that reflect your actual work history and reasonable future expectations. Keep a note of the assumptions so you can revisit them as your plans change.

4. 04

   Plan for work and other income

   If you expect to earn wages while receiving benefits, check the current earnings-test rules with Social Security. Include savings, pensions, and other income in your retirement budget rather than treating this estimate as your only source of income.

Common Social Security calculator mistakes

• Using current salary as your indexed average

  Current pay may not represent your average indexed earnings over your work history. Check your earnings record and choose the input that best matches what the calculator asks for.

• Treating the estimate as a guaranteed payment

  The result depends on the information you enter and the formula used for the estimate. Confirm your official benefit amount and claiming details with Social Security.

• Comparing benefits without comparing timing

  A larger monthly benefit from waiting does not show how much income you would forgo before claiming. Compare the estimates with your cash needs, health, work plans, and savings.

• Overlooking the earnings test

  If you claim and continue working, the earnings test may affect benefits. Check the Social Security Administration’s current rules rather than assuming this calculator accounts for your wages.
