The calculator uses the Social Security benefit formula:

Explanation: Benefits are reduced if taken before full retirement age and increased if taken after. COLA adjustments are applied to account for inflation.
Details: Understanding your estimated benefit helps with retirement planning, determining the optimal age to claim benefits, and budgeting for retirement expenses.
Tips: Enter your PIA (available from your Social Security statement), your planned retirement age (62-70), your full retirement age (66-67), and any expected COLA adjustments.
                    Q1: What is PIA?
                    A: Primary Insurance Amount is the benefit you'd receive at full retirement age, based on your 35 highest-earning years.
                
                    Q2: What's the earliest I can claim benefits?
                    A: The earliest is age 62, but benefits are reduced by about 30% if your FRA is 67.
                
                    Q3: How do delayed credits work?
                    A: For each month you delay past FRA up to age 70, your benefit increases by about 0.67%.
                
                    Q4: Are COLAs guaranteed?
                    A: No, COLAs are determined annually based on inflation and are not guaranteed every year.
