New Jersey Post-Judgment Interest Rate: 2026 and 2027 Rates Explained
The Interest Rate Changes Every Year
Post-judgment interest in New Jersey isn't a fixed number. It's recalculated annually based on the average rate of return of the State of New Jersey Cash Management Fund, then published by the courts under Rule 4:42-11.
Here are the current rates:
| Year | Judgments up to $20,000 | Judgments over $20,000 |
|---|---|---|
| 2024 | 3.50% | 5.50% |
| 2025 | 5.50% | 7.50% |
| 2026 | 4.50% | 6.50% |
| 2027 | 4.00% | 6.00% |
Most small claims judgments fall under the $20,000 Special Civil Part cap, so you'll use the lower rate column. Judgments exceeding $20,000 (Law Division) get a 2% premium on top of the base rate under Rule 4:42-11(a)(iii).
How to Calculate Interest on Your Judgment
New Jersey uses simple interest, not compound. The formula:
Annual Interest = Unpaid Principal × Post-Judgment Rate
For a $4,000 judgment entered on March 1, 2026:
- March–December 2026 (10 months): $4,000 × 4.50% × (10/12) = $150.00
- January–December 2027 (if still unpaid): $4,000 × 4.00% = $160.00
Interest accrues on the unpaid principal balance, not on previously accrued interest. When partial payments come in — whether through voluntary payment, a bank levy, or wage garnishment — they're applied first to accrued interest and court execution costs, then to reduce the principal.
Interest Starts Automatically
You don't need to file anything to start earning post-judgment interest. It accrues automatically from the date of judgment entry under Rule 4:42-11. You also don't need the debtor's agreement — the interest is statutory, meaning it's built into New Jersey law.
When you later file for a Writ of Execution or bank levy, include the accumulated interest in the total amount. The court officer collects interest alongside the principal judgment amount.

The $5,000 Cap Doesn't Cap Interest
A common point of confusion: the Small Claims Section handles judgments up to $5,000, but post-judgment interest, court costs, and execution fees can push the total balance above $5,000. This is legal. The jurisdictional limit applies to the original claim, not to the accumulated enforcement total.
On a $5,000 judgment, one year of interest at the 2026 rate of 4.50% adds $225 — before any execution fees. The debtor owes the full amount.
Interest Rates Affect Your Collection Strategy
When interest rates are higher, time works in your favor. At the 2026 rate of 4.50%, every month of delay costs the debtor another $18.75 on a $5,000 judgment. This can motivate settlement — a debtor who offers to pay the principal amount may not realize they also owe accumulated interest plus execution fees.
Conversely, if you're spending $35 per Writ of Execution and $7 per service attempt, calculate whether the interest accrual covers your enforcement costs. On a small judgment under $1,000, enforcement fees can eat into your net recovery even with interest running.
Where to Find the Official Rate
The New Jersey Judiciary publishes annual rate notices at njcourts.gov. Search for "post-judgment interest rate" or "Rule 4:42-11" on the notices page. The 2027 rate (4.00%) was announced in the Notice to the Bar dated July 21, 2026.
