Understanding Prejudgment Interest in Small Claims Court

Of everything that goes into a Small Claims Court claim, prejudgment interest is probably the least intuitive — and the most commonly left on the table. It doesn't show up in the dramatic parts of a case, but it can meaningfully change what you actually walk away with.

The idea, in one sentence

Money owed to you today is worth more than the same amount owed to you two years from now — and prejudgment interest exists to compensate for that gap between when you were first owed the money and when a judgment finally puts a number on it.

Why the law bothers with this at all

Without prejudgment interest, there would be a strange incentive built into the system: a defendant who delays and drags out a case would effectively benefit from that delay, holding onto money they owe for longer at no additional cost. Prejudgment interest removes that perverse incentive by recognizing that time itself has value, and that a plaintiff shouldn't be worse off simply because a dispute took a while to resolve.

The part people consistently miss

Here's the part that trips people up: prejudgment interest generally isn't calculated or added automatically just because you were owed money. If you don't specifically claim it as part of your case, you can end up with a judgment for exactly the original amount, missing out on everything that accrued while the dispute was working its way through the process. The fix is simple once you know about it — but it's an easy detail to overlook if nobody tells you it exists.

How it actually adds up over time

The core mechanics are straightforward: interest generally accrues on the amount you were owed, calculated from around the time the debt or loss arose through to the date judgment is issued. The longer that period stretches — and disputes can easily take many months from the original event to a final decision — the more this figure can grow. For a dispute that's dragged on, it's often a bigger number than people expect.

It doesn't count against the monetary limit

One reassuring detail: prejudgment interest is generally treated separately from Small Claims Court's monetary limit. That means even a claim already at the upper edge of the limit can still potentially include additional prejudgment interest on top, without that interest needing to somehow fit inside the same ceiling.

The other side of a judgment: postjudgment interest

Prejudgment interest covers the period before a decision is made. A related but separate concept, postjudgment interest, picks up from there — covering the period after judgment while it remains unpaid. Together, they mean that time spent either preparing a case or waiting to be paid after winning isn't simply lost value for the person who's owed money.
