Wyo. Stat. §40-14-106(e) supplies a 7% legal-rate reference when an agreement does not set a rate. Wyoming prejudgment entitlement arises from the governing obligation and case law, not from that percentage alone. A claim generally must be readily computable without opinion or discretion before the rate can be used.
When Wyoming prejudgment interest applies
Prejudgment interest is available ONLY on LIQUIDATED claims — a claim that is "readily computable by basic mathematical calculation." An otherwise-unliquidated claim qualifies only if it becomes determinable "without reliance on opinion or discretion." BARRED on unliquidated claims and on amounts requiring the exercise of judicial discretion or opinion (e.g., attorney-fee awards, which are not a mathematical computation — Thorkildsen v. Belden LLC, 2012 WY 8).
When it starts accruing
Accrues from the date the debtor receives notice of the amount due (i.e., when the liquidated sum becomes due and demand/notice is made), running until judgment.
Simple or compound
The legal-rate provision does not establish one universal prejudgment compounding method. Confirm the agreement, controlling case law, and judgment before calculating.
→ Compare with the Wyoming post-judgment interest rate (interest after judgment)
Prejudgment interest under Wyo. Stat. Ann. Sec. 40-14-106(e) — 7% (simple interest). This is PREjudgment interest (accruing before entry of judgment) and is separate from Wyoming’s post-judgment rate; availability is limited by claim type (see the page). Verify against the statute text. Not legal advice.
