Since asking for financial help on New Year's Eve, parishioners have donated close to $2.5 million to the church.
He made the announcement during a sermon at the church on Saturday.
Thursday, Warren posted an urgent letter on his church's website asking for $900,000.
The pastor said expenses are up because parishioners are out of work and the "bottom dropped out" when year-end donations dropped dramatically.
Warren said the new donations are "amazing" and says the church will now start the new decade with a surplus.
