When Can You Legally Charge Pre-Judgment Interest?
In American civil jurisprudence, pre-judgment interest serves to compensate a plaintiff for the lost time-value of their funds during the interval between the defendant's breach and the ultimate trial judgment.
Under common law and state codifications, pre-judgment interest is routinely awarded as a matter of right when the underlying damages are liquidated:
- Liquidated Claims (Interest Permitted): Unpaid invoices, dishonored promissory notes, withheld residential security deposits, completed construction milestones, or any fixed debt where the dollar amount was known or mathematically determinable on the date of default.
- Unliquidated Claims (Interest Generally Denied Prior to Verdict): Pain and suffering, general tort damages, disputed auto body repair estimates, or contested reasonable value (quantum meruit) claims where a jury or judge must establish the fair value.

Frequently Asked Questions
Does pre-judgment interest count toward the Small Claims limit?
In most US states (including California, Illinois, Florida, and Texas), pre-judgment statutory interest and court costs are calculated separately from the statutory dollar ceiling. For example, in a $10,000 court limit, you can claim $10,000 in principal plus $800 in interest.
What if my debtor pays the principal but refuses to pay interest?
Under the common law partial payment rule, payments are applied first to accrued interest and then to the principal balance. The debtor remains liable for the residual principal unless you agree in writing to waive it.
Is daily interest calculated on 365 or 360 days?
Under modern civil procedure, 365 days (actual/365) is the accepted legal standard in all state courts.
