How to use this calculator
Compare retirement benefits for application ages from 62 through 70. Enter amounts in the units shown, select the applicable options, and click Calculate. Use Reset to restore the starting values.
Calculation formula
Early claim reductions: 5/9% for first 36 months, 5/12% thereafter; delayed retirement credits: 2/3% per month through age 70.
Assumptions and accuracy
Review timing, rates, fees and result notes when comparing scenarios. Future returns and rates are assumptions rather than guaranteed outcomes. Monetary display follows the currency’s precision; intermediate calculations retain additional digits.

Worked examples
Compare benefit streams over a short illustrative lifespan
Illustrative inputs are specified in the steps below; the example link loads the complete settings. Unmentioned settings use the linked defaults.
- Claiming at 62 pays 24 months of 1,000 before assumed age 64, totaling 24,000 without discounting. Delaying to 63 leaves 12 months of 1,100, totaling 13,200. Actual lifetime and eligibility are uncertain.
First option present value: 24,000 USD.
Try these inputsCommon questions
Does the highest monthly Social Security payment mean the best claiming age?
No. Delaying also means forgoing earlier payments. Lifespan, discount rate and COLA assumptions influence the comparison.
Should I enter an official benefit estimate?
Use an applicable estimate when possible and verify its assumptions. This tool cannot infer your actual earnings record or entitlement.
Scope and assumptions
This is a simplified individual planning model, not an SSA entitlement calculation. Spousal, survivor, work-history and earnings-test rules are not fully modeled.
