About 40% of Americans claim Social Security benefits at age 62, according to retirement data. This early filing decision can quietly reduce lifetime Social Security benefits by more than $100,000. Many retirees focus on quick income, but overlook how Social Security claiming age shapes long-term retirement income. Filing early cuts monthly payments by nearly 30% compared with full retirement age benefits. In contrast, delaying Social Security until age 70 can significantly increase monthly checks through delayed retirement credits. With inflation, healthcare costs, and longer life expectancy rising, choosing the right Social Security claiming strategy has become essential. One timing mistake today can reshape retirement finances for decades.
