CIS is usually calculated on labour (and some related costs), not qualifying materials. This is a quick estimate only.

Using a CIS deduction calculator

Enter the labour amount, qualifying materials, and the CIS rate to estimate a deduction. This helps contractors and subcontractors sense-check payments before invoices are settled.

For operational teams, linking quoting, jobs, and costs in one place can reduce admin time and payment disputes.
