It shows whether the payment is still within the grace period, the last date to pay, and the expected surcharge.

Some jurisdictions apply a fixed surcharge when the renewal is paid during the grace period. This makes the late fee easier to estimate once the jurisdiction and deadline are known.
Examples: United States, Japan, Canada, Singapore, Israel
Some jurisdictions calculate the surcharge as a percentage of the underlying annuity fee. This means the late payment cost scales with the size of the renewal fee and, in some cases, how late the payment is.
Examples: Brazil, China, India, South Africa, European Patent Office
Some countries use more specific rules, where the surcharge may depend on the annuity year, grant status, monthly delay, or local patent office logic. These cases often need closer review before the exact late fee is confirmed.
Examples: Argentina, Colombia, Taiwan, Mexico, Guatemala
