Oregon prejudgment interest is 9% per year, as simple interest under ORS 82.010(1)(a). Prejudgment interest is NOT automatically available on all claims.
When Oregon prejudgment interest applies
Prejudgment interest is NOT automatically available on all claims. It runs on "all moneys after they become due" (ORS 82.010(1)(a)) and Oregon courts have restricted it to claims where (1) the exact amount of damages is ASCERTAINED or ASCERTAINABLE by simple computation or by reference to generally recognized standards, AND (2) the time from which interest runs (when the money became due) is easily ascertained. Classic use: liquidated contract/debt claims, money had and received, open accounts.
When it starts accruing
Interest accrues from the date the money became due / the loss was sustained, i.e., when the ascertainable sum first became payable. For open accounts, from the date of the last item. For services (quantum meruit), from the date service was rendered.
Simple or compound
Simple interest. ORS 82.010 provides simple interest (subsection (2)(b) expressly makes judgment interest simple unless a contract provides otherwise; the (1) legal rate is likewise applied as simple interest per annum).
→ Compare with the Oregon post-judgment interest rate (interest after judgment)
ORS 82.010 supplies a 9% rate for qualifying amounts, but the section does not itself create entitlement to prejudgment interest. Availability and the accrual date depend on the underlying claim and Oregon case law. Simple-interest reference only; confirm the controlling rule. Not legal advice.
