For accurate information see The 2018 Annual Report of the Board of Trustees of the Federal Old-Age and Survivors Insurance and Federal Disability Insurance Trust Funds:
"Asset reserves" were $2,891.8 billion at the end of 2017.
The "net increase in asset reserves in 2017" was $44.1 billion.
> The asset reserves of the combined trust funds were $2.9 trillion at the end of 2017. The trust fund reserves decline on a present value basis after 2017, but remain positive through 2033. However, after 2033 this cumulative amount becomes negative, which means that the combined OASI and DI Trust Funds have a net unfunded obligation through each year after 2033. Through the end of 2092, the combined funds have a present-value **unfunded obligation of $13.2 trillion**.
