NDA Duration Calculator
Determine the appropriate non-disclosure agreement duration based on information type, industry, and risk level.
Recommended NDA Terms
NDA (Non-Disclosure Agreement) duration depends on the type of information being protected.
Typical NDA durations by information type:
| Information Type | Typical Duration | Notes |
|---|---|---|
| Trade secrets | Indefinite | Protected as long as they remain secret |
| Business plans | 2-3 years | Plans become outdated |
| Customer lists | 3-5 years | Lists change over time |
| Financial data | 2-5 years | Becomes less sensitive with age |
| Technical specs | 3-5 years | Technology evolves |
| Software code | 3-7 years | Depends on lifecycle |
| Employee data | 5+ years | Privacy laws may extend this |
Two durations matter:
- Agreement term — how long the NDA relationship lasts
- Survival period — how long confidentiality continues AFTER the agreement ends
Industry norms:
- Technology: 2-5 years
- Healthcare: 5-10 years
- Finance: 3-7 years
- Manufacturing: 3-5 years
- Entertainment: 2-5 years
