Rhode Island Post-Judgment Interest Rate

Rhode Island's 12% Statutory Rate

Under R.I. Gen. Laws § 9-21-10, post-judgment interest in Rhode Island accrues at 12% per annum as simple interest. This rate applies automatically to the unpaid principal balance from the date judgment enters until the judgment is satisfied in full. You do not need to ask the court for it — it runs by operation of law.

At 12%, Rhode Island has one of the higher post-judgment interest rates in the country. Many states set theirs between 4% and 10%, and some peg it to fluctuating Treasury rates. Rhode Island's rate is fixed by statute and does not change with federal interest rate movements.

What 12% Means on a Small Claims Judgment

Rhode Island small claims judgments can be up to $5,000 (exclusive of interest and court costs). Here is what the interest adds on common judgment amounts over time:

On a $5,000 judgment, you earn $50 per month in interest. Over the full 20-year enforcement period (R.I. Gen. Laws § 9-1-17), that same judgment would accrue $12,000 in interest alone — more than doubling the original award.

Simple Interest, Not Compound

Rhode Island's post-judgment interest is simple interest, calculated on the original principal balance only. Interest does not compound on itself. The formula is straightforward:

Interest = Principal × 0.12 × (Days Outstanding ÷ 365)

For a $3,000 judgment that has been unpaid for 200 days: $3,000 × 0.12 × (200 ÷ 365) = $197.26.

How Interest Interacts With Partial Payments

When the debtor makes a partial payment, standard practice allocates the payment first to accrued interest and recoverable costs before reducing the principal balance. This matters because it means the principal — which continues generating interest — stays higher for longer.

For example, on a $3,000 judgment with $360 in accrued interest and $65 in court costs after one year: if the debtor pays $400, that covers the $65 in costs and $335 of the accrued interest, leaving $25 in unpaid interest and the full $3,000 principal still generating 12% annually.

Maintaining an accurate payment ledger is essential. Track the date and amount of every payment, the allocation between interest/costs/principal, and the resulting balance. If you ever need to apply for additional enforcement (a second writ of execution, for instance), the court will expect you to state the exact amount owed including accrued interest.

Recoverable Costs on Top of Interest

Interest accrues on the principal judgment amount. Court costs and enforcement expenses — the $20 writ issuance fee, officer service deposits around $45, and the original filing fee — are recoverable on top of the interest. They get added to the total balance the debtor owes but do not themselves generate interest.

The total enforcement balance at any point is: unpaid principal + accrued simple interest on principal + unreimbursed recoverable costs.

Interest as a Collection Motivator

The 12% rate works in the creditor's favor as a motivator. A debtor who ignores a $3,000 judgment sees it grow by $30 every month. Over two years of avoidance, the $3,000 becomes $3,720 before any enforcement costs are added. Making this clear in a written demand letter — stating the exact daily interest accrual alongside the total balance — can sometimes prompt voluntary payment from debtors who understand the math.
