As much as you pay out before the client pays you. If you pay subcontractors and suppliers before the client's money arrives, the job runs on your cash until it does. The calculator works out the most it needs and for how many days.
Free, with no sign-up. Everything is worked out in your browser: nothing you type is sent to us or stored. Use figures excluding VAT.

Every number this tool works with is one you enter. It uses no outside rate, threshold or date, so there is nothing to look up.
SUBR is AI software for UK contractors who send work out to subcontractors. Its AI reads your client quote, your office names each trade's share, and SUBR builds every scope with your costs, margin and client price left off it. Each subcontractor answers on their own link and sees only their own price.
