Free calculator - Duration of ISO 45001 implementation

This calculator will help you estimate the time needed for your ISO 45001:2018 implementation.

Please enter the data only for the scope of your OH&SMS (Occupational Health & Safety Management System) - if your scope is smaller than the whole company, please do not enter the data for your whole company. E.g., if your company has 1000 employees, but the scope of implementation includes only 30 employees, your answer to question #1 will be “21 to 50.”

Note: We won't share your information with anyone.









Note: If the project duration exceeds 24 months, the project will fail.
Please note that this estimate is calculated on the basis of normal implementation workload - that is, the implementation is done at a pace that doesn't require employees to work long hours of overtime. This kind of project could be done faster than this estimate shows, but it means that some other projects would have to be neglected, and that stress for the implementation team would be much higher.
