Post-judgment interest in Connecticut
An unpaid Connecticut money judgment earns interest at a rate the judge sets, up to 10% a year. At that ceiling a $5,000.00 judgment earns $500.00 in the first year, about $1.37 a day; your judgment states the actual rate.
How the rate is set
Up to 10% a year, at the court's discretion. The statute sets a ceiling, not a rate: the judge may award any rate up to 10%, or none. The figure shown is that ceiling.

How Connecticut's rate is set, and where it comes from
Uses simple interest at the rate you enter — pre-filled with each state's standard statutory rate, editable since some states publish a new rate quarterly or annually. Some states apply a different rate to specific debt types (noted above where it applies) or when a contract specifies its own rate. Informational only, not legal advice; confirm the current rate and any exceptions with your court clerk before relying on this figure.
The formula, worked
Last reviewed: October 2026
Interest = principal × rate × days ÷ 365. For $5,000.00 at the 10% ceiling: $5,000.00 × 0.10000 × 365 ÷ 365 = $500.00 after one year, and $1.37 for each further day.
What this page does not know
- The rate written on your judgment. If the court stated a rate, that one applies, whatever the default is today.
- Partial payments. Interest accrues only on what is still unpaid.
Informational only, not legal advice. Every figure is cited to the statute or the office that publishes it; confirm the current rate with the court clerk before relying on it.
