Calculate liquidated damages for contract breaches using per-day delay rates or fixed per-occurrence amounts. Estimate total exposure instantly.
Liquidated damages (LDs) are a pre-agreed sum that one party must pay the other if a contract is breached, most commonly for late delivery or project delays. Unlike penalties, liquidated damages represent a genuine pre-estimate of the loss the non-breaching party would suffer.
This calculator computes total liquidated damages based on either a per-day delay rate or a fixed amount per occurrence. It is widely used in construction, software development, manufacturing, and supply contracts where timely performance is critical.
Courts generally enforce liquidated damages clauses if the amount is a reasonable estimate of anticipated damages and actual damages would be difficult to calculate at the time of contracting. Amounts that are grossly disproportionate may be struck down as unenforceable penalties.
Legal professionals, business owners, and individuals alike benefit from transparent liquidated damages calculations when evaluating obligations, settlements, or compliance requirements.

Quickly computing LD exposure helps project managers assess schedule risk, negotiate reasonable LD rates, and make informed decisions about acceleration costs versus delay damages. Instant recalculation as you change inputs lets you model multiple scenarios quickly, giving you the data foundation needed for well-informed legal and financial decisions.

Total LDs = Per Day Rate × Days of Delay Capped LDs = min(Total LDs, Contract Value × Cap %) LD as % of Contract = (Total LDs / Contract Value) × 100
Result: $45,000 in liquidated damages
Total LDs = $1,500/day × 30 days = $45,000. Cap = $500,000 × 10% = $50,000. Since $45,000 < $50,000, the full amount applies. LDs represent 9% of contract value.
Federal and state government contracts commonly include LD provisions for construction projects. The Federal Acquisition Regulation (FAR) requires LD rates to be based on engineering estimates of the government's actual daily cost of delay.
The Restatement (Second) of Contracts provides that LDs are enforceable if: (1) the amount is reasonable in light of anticipated or actual loss, and (2) actual damages would be difficult to prove. Most states follow this two-part test.
Contractors should negotiate LD provisions carefully. Request a reasonable cap, a grace period before LDs begin, exclusions for owner-caused delays, and clear milestone definitions to avoid ambiguity about when delays begin and end.
Liquidated damages are a genuine pre-estimate of loss from breach. Penalties are amounts designed to punish, not compensate. Courts enforce liquidated damages but may void penalties as unconscionable.
Rates vary by project size and type. Government projects may specify $500–$5,000 per day. Large commercial projects can see $5,000–$50,000 per day. The rate should approximate the owner's actual daily cost of delay.
A cap limits the maximum total LDs. Common caps are 5–15% of the contract value. Without a cap, LDs could theoretically exceed the contract price if delays are long enough.
Yes. A party can argue that the LD amount is an unenforceable penalty if it is grossly disproportionate to actual damages. Courts examine whether the amount was reasonable when the contract was formed.
LD clauses typically state they are the exclusive remedy for the specified breach (e.g., delay). The non-breaching party cannot claim both LDs and actual delay damages for the same breach.
Yes. While per-day delay LDs are most common, contracts can specify fixed LDs per occurrence of specific breaches, such as each failed service level or each defective unit delivered.
