It's possible to get Social Security pay increased by working for a minimum of 35 years, increasing income, claiming Social Security once full retirement age is reached, waiting to claim until the age of 70, taking advantage of spouse benefits, and including dependents in claims. Other options include taking advantage of benefits from an ex-spouse's work, trying not to earn too much income while retired, trying to keep taxes down, receiving payments by direct deposit, and checking statements annually.
Social security payouts are calculated based on the 35 most lucrative years of work, so if an individual has not worked for at least 35 years, that is money lost. The longer an individual works, the more chance she has of replacing low income earned early on with higher income earned later, which enhances the later payout. Earning more in general also helps, for a similar reason. This can come from a raise or a second job.
People who sign up for social security before they reach full retirement age will get lower payments per month from Social Security. The full benefit comes from signing up at 66 or 67 for most people or delaying claiming until the age of 70. This is because payments per month increase 8% for each year that claiming is delayed.
