Connecticut does not apply one automatic 10% rate to every judgment. Under Conn. Gen. Stat. §37-3a, a court may award up to 10% per year as damages for detention of money; qualifying hospital-service debt is capped at 5% and remains discretionary. Section 37-3b separately requires 10% in covered negligence actions, while §37-3c uses a Treasury-linked condemnation rule.

How Connecticut post-judgment interest works

Which rate applies

Section 37-3a supplies a discretionary rate of up to 10% for qualifying detention-of-money claims and a 5% cap for hospital-service debt. Section 37-3b governs covered negligence judgments. Section 37-3c governs condemnation awards, and §52-192a can create another offer-of-compromise path.

When interest accrues

For a negligence cause of action arising on or after May 27, 1997, §37-3b computes interest from the earlier of 20 days after judgment or 90 days after verdict. A plaintiff’s own postverdict motion or appeal can toll interest, subject to the statute’s response exception.

Compounding and rate lock

Because entitlement, start date, percentage, tolling, claim type, and the condemnation calculation differ by branch, StatuteRates treats 10% as a ceiling/reference—not a universal calculator input—and keeps the Connecticut payoff calculator disabled.

Statutory basis & carve-outs. Connecticut does not set one automatic percentage for every judgment. Section 37-3a permits up to 10% as damages for qualifying detention of money and caps hospital-service debt at 5%, with awards discretionary. For covered negligence causes arising on or after May 27, 1997, §37-3b requires 10% from the earlier of 20 days after judgment or 90 days after verdict, subject to plaintiff-motion and appeal tolling. Section 37-3c uses a separate Treasury-linked condemnation formula. Verify the applicable branch; not legal advice.
