CIDB Grade Calculator
Estimate a possible CIDB grade based on your financial capability and track record. Essential for South African construction tenders.
Estimation Only
This tool estimates your grade based on the criteria. It is not an official grading. You must apply to the CIDB for a valid grade. Check an existing CIDB registration to see the grade recorded by CIDB.
Calculate Your Grade
Why is this important?
CIDB grading indicates the contract value and class of work for which a contractor is registered. Check your registered designation and the tender conditions before bidding.
Common Grades:
- Grade 1Up to R500k
- Grade 4Up to R6 Million
- Grade 7Up to R60 Million
- Grade 9Unlimited
Understanding Classes
Joint Ventures (JV)
For Joint Ventures, the CIDB uses a specific calculator to combine the grades of all partners.
Example: Two Grade 4 CE companies can typically tender for Grade 5 CE contracts.
The lead partner must have a satisfying grade (usually one level below the target).
How is CIDB Grading Calculated?
The Construction Industry Development Board (CIDB) uses two primary factors to determine your grading:
- Financial Capability: Assessed via your best annual turnover (over the last 2 years) and your valid net asset value (or available capital/sponsorship).
- Works Capability: Assessed via the largest single contract you have successfully completed in the last 5 years within your specific class of works.
Additional factors like "Potentially Emerging" (PE) status can allow you to tender one grade higher than your processed grade, subject to certain conditions.
Frequently Asked Questions
Can I tender for a grade higher than my current grading?
Generally, no. You are restricted to tenders within your grade (and lower grades). However, if you are registered as Potentially Emerging (PE), you may be eligible for tenders one grade higher in certain development programs.
How long does my CIDB registration last?
CIDB registration is valid for 3 years, but you must pay an annual update fee to remain active. You must also apply for a 3-year renewal before your registration expires.
Can I upgrade my grade immediately?
Yes, as soon as you have completed a larger contract that meets the requirements for the next grade and have the necessary financial statements to prove your capability, you can apply for an upgrade.
