The California Policy Center estimates Required Pension Contributions Will Nearly Double in 5 Years. I claim it will be much worse.

In the fiscal year beginning in July, local payments to the California Public Employees' Retirement System will total $5.3 billion and rise to $9.8 billion in fiscal 2023, according to the right-leaning group that examines public pensions.

The increase reflects Calpers' decision in December to roll back the expected rate of return on its investments. That means the system's 3,000 cities, counties, school districts and other public agencies will have to put more taxpayer money into the fund because they can't count as heavily on anticipated investment income to cover future benefit checks.

Including the costs paid by cities and counties that run their own systems, the fiscal 2018 tab will be at least $13 billion to meet retirement obligations for public workers, according to the analysis, which is based on actuarial reports and audited financial statements.
