To calculate your SSS pension in the Philippines, you need to determine your average monthly salary credit (AMSC) based on your highest 60 monthly contributions. The formula used considers factors like the number of years of contribution and your salary history. You can also use the online SSS pension calculator for an estimate, or you may contact SSS directly to help you calculate SSS pension more accurately. It’s important to meet the minimum contribution requirements to be eligible for the pension, which can vary depending on your retirement age and number of years of service.
