Legal analysis: the amount of liquidated damages for delayed payment in the contract can be determined by both parties through consultation. The principle of agreeing on liquidated damages is: (1) Before agreeing on the terms of liquidated damages, one party should fully evaluate the amount of losses that may be suffered by breach of contract, and on this basis, correctly agree on the amount or calculation method of liquidated damages. (2) If the loss of the observant party cannot be assessed, it is best not to agree on a clear amount of liquidated damages or other calculation methods, but to use the total contract amount instead.

Legal basis: Civil Code of People's Republic of China (PRC).

Article 577 Where a party fails to perform its contractual obligations or fails to perform its contractual obligations in conformity with the contract, it shall be liable for breach of contract such as continuing to perform, taking remedial measures or compensating for losses.

Article 582 Where the performance is not in conformity with the agreement, it shall bear the liability for breach of contract in accordance with the agreement of the parties. If the liability for breach of contract is not stipulated or clearly stipulated and cannot be determined according to the provisions of Article 510 of this Law, the injured party may reasonably choose to require the other party to bear the liability for breach of contract such as repair, rework, replacement, return, price reduction or remuneration according to the nature of the subject matter and the size of the loss.

Article 585 The parties may agree that one party shall pay a certain amount of liquidated damages to the other party for breach of contract, or may agree on the calculation method of the amount of compensation for losses caused by breach of contract.

If the agreed liquidated damages are lower than the losses caused, the people's court or arbitration institution may increase the liquidated damages at the request of the parties; If the agreed liquidated damages are excessively higher than the losses caused, the people's court or arbitration institution may appropriately reduce them at the request of the parties.

If the parties concerned pay liquidated damages for delayed performance, the breaching party shall also perform the debt after paying the liquidated damages.
