In California Post Judgment Interest – which is interest that accrue after you have obtained a judgment against someone or entity is as follows:
The Judgment amount multiplied by 10% divided by 365 days = the daily interest amount.
So say you have a Judgment against someone for $5,000.00. The daily interest that is added to your judgment is: 5000 x 0.10 / 365 = $1.37
So for each day that you judgment goes uncollected after it was awarded, you earn $1.37 or $1.37 is added to your judgment for each day that it goes uncollected.
