The paper says that by claiming benefits early, Americans are leaving lifetime benefits on the table. To see how, consider Social Security break-even ages, which are the ages at which the total benefits from claiming at two different ages equal out.

The break-even age for claiming between 62 and 70 is around 80.4. Before that age, you would've received more lifetime benefits by claiming at 62. After that age, you would receive more lifetime benefits by claiming at 70. Social Security's average life expectancy at 62 is 81.61 for men and 84.5 for women. This means, on average, someone would have received more benefits by waiting until 70 versus claiming at 62.

Always consider your personal situation

Just because the data says 70 is the best claiming age, that doesn't mean it's the best claiming age for you. If you need Social Security for a good portion of your retirement income, claim it as soon as you need to ensure your expenses are covered. If personal or family health issues are a concern, claim as soon as you see fit.

However, if you can reasonably survive without Social Security, consider delaying to give yourself a better chance at maximizing your lifetime benefits.
