A warranty calculator is a digital tool that automatically determines the coverage period of a product based on its purchase date and warranty length. It can quickly calculate the expiration date of a warranty, check if a claim falls within the warranty period, and even estimate the remaining days of warranty coverage. This simple yet powerful tool takes the guesswork out of warranty management, ensuring that users can make informed decisions regarding their purchases and warranty claims.

  2. code warranty expiration date = purchase date + warranty length
  3. Check if Claim is Within Warranty: Verifies whether a claim is made during the warranty period.
