Post-judgment interest
Colorado's post-judgment interest rate is 8% per year. Colorado money judgments accrue 8% per year, compounded annually, under C.R.S. §5-12-102(4)(b) when no contract rate applies. Personal-injury judgments use a separate rate (§13-21-101), and judgments on appeal use a variable rate certified each January by the Secretary of State.

Prejudgment interest
Colorado's prejudgment interest rate is 8% / 9% per year (fixed by statute). Colorado has two prejudgment interest rates, both compounded annually: 8% per year for general and contract claims and money or property wrongfully withheld (C.R.S. §5-12-102(1)(b)), and 9% per year for personal-injury actions (C.R.S. §13-21-101), which §5-12-102 expressly carves out. Colorado is unusually broad — prejudgment interest is NOT limited to liquidated or ascertainable sums.
