For the government pensions it’s easy to calculate. It’s 1% for each year of service against an average of youtube high 3 salaries. So a 40 year career will get you a 40% salary pension. The old fed pensions and many state pension now are way overly generous.
Social security is a BS scam. Someone who pays in half as much gets 80% of the benefit. The third bend point is 15$. To understand how SS funnel monies to lower payed people you have to understand the bend points.
Percentages don't mean much, total amount of the payout to each system is the only thing that matters to me. Maybe one is way bigger than the other maybe not.
