Most NDAs separate agreement duration from confidentiality obligations. A fixed agreement term can be 12 to 36 months for evaluations, pilots, and vendor onboarding, while the confidentiality term often runs longer. Many commercial NDAs set confidentiality at 24 to 60 months, and some carve out trade secrets for ongoing protection. This calculator models both timelines so you can see when operational duties end versus when information must remain protected.
Confidentiality can be measured from the effective date or from the last disclosure. Measuring from the last disclosure is useful when information is exchanged over multiple meetings, releases, sprints, or data rooms, because the protection window resets with the latest transfer. Choosing the correct base reduces undercounting and helps align internal reminders with the clause your teams actually follow. If disclosures continue, update the last disclosure date to keep the estimate current.
Many NDAs include survival language stating that certain sections remain in force after termination. When a termination date exists, a survival period may set a minimum protection window, even if the confidentiality term would otherwise end sooner. Common survival windows are 6, 12, or 24 months, but the contract controls. The calculator therefore applies the later of the confidentiality end date and the survival end date to reflect that minimum.
Remaining days provide a practical control for contract operations. If the agreement is still active, you can schedule renewal notices, access reviews, and clean‑room data deletion tasks. If confidentiality is nearing its end, you can plan returns or destruction certifications and confirm whether any exceptions require longer handling. Tracking remaining time also supports onboarding checklists, offboarding, and re‑acknowledgment of confidentiality policies.
A consistent export format makes audits easier. The CSV download captures inputs and outputs in one snapshot for ticketing, vendor files, and contract repositories. The PDF summary supports sharing with stakeholders who need a record for approvals and compliance. Use the notes field to reference amendment dates, disclosure channels, internal policy IDs, and the business owner responsible for follow‑up actions.
Perpetual means no fixed end date is calculated. The tool shows “No fixed end date” and skips remaining‑day figures. Confirm whether your NDA limits certain categories, such as public information, independently developed work, or trade secrets.
Choose agreement start when disclosures are essentially one‑time or tied to signing. Choose last disclosure when information is exchanged over time. If disclosures continue, update the last disclosure date so the estimate reflects the latest transfer.
Months and years are added using calendar intervals. For example, adding one month to January 31 may roll to the closest valid date in the next month, depending on the calendar. Always compare against any anniversary wording in the signed document.
If survival is enabled and a termination date is provided, the calculator computes a survival end date and then uses the later of that date and the confidentiality end date. This reflects clauses that keep obligations alive after termination.
No. Remaining days are a planning indicator based on today’s date and your selected rules. Actual deadlines can differ due to amendments, notice periods, business‑day definitions, or governing law. Treat the output as operational guidance, not legal advice.
Use notes to capture context that supports audits: amendment dates, disclosure channels, internal ticket links, data return or destruction commitments, and the business owner. Keeping these references with the export helps teams reconcile obligations later.
