How to use this tool

  1. 1Enter the contract end date (or renewal date).
  2. 2Enter the notice window: single value (e.g., "60 days' notice") OR range (e.g., "not less than 60 and not more than 90 days").
  3. 3Choose whether notice must be received by or sent by the deadline.
  4. 4Add a delivery buffer (recommended: 7 days for mail, 2-3 days for email + internal approvals).
  5. 5Copy the results and set your reminders.

What the results mean

If a contract says notice must be received by a certain day, sending on that day is often too late.

The calculator uses your buffer to create a "send-by" date that is more realistic operationally.

If your contract has a range window (60–90 days), the safe move is usually to plan to send near the earlier end of the window (e.g., 90 days before), so you don't get trapped by delays or internal approvals.

Common pitfalls

  • Confusing "renewal date" vs "end date"
  • Missing that notice must be received, not sent
  • Not accounting for internal approvals (legal/procurement)
  • Sending notice to the wrong party/address in the contract
  • Assuming email is always valid notice (some contracts require specific methods)
