When is a liquidated damages clause enforceable?

US courts enforce LD clauses when actual damages would be hard to prove and the LD amount is a genuine pre-estimate of loss. Clauses intended to penalize (rather than compensate) are usually unenforceable.

How high can a liquidated damages rate be?

In construction contracts, common rates are 0.05–0.15% of contract value per day of delay. Courts have enforced rates up to 0.5%/day in high-urgency projects. Higher rates risk being classified as penalties.
