How much of a deposit should I charge for a job?

Start with what you have to spend before getting paid

List materials that must be ordered, permits, rentals, subcontractor commitments and other cash the business must put out before meaningful work is completed. A deposit can reduce the amount the business has to finance for the customer.

Think about the size and length of the job

For a short job, a deposit plus final payment may be simple. For a longer project, a smaller initial deposit followed by clearly defined progress payments can keep cash flow aligned with the work.

Do not use the deposit as the whole profit plan

A deposit changes when cash arrives; it does not fix an underpriced job. The full contract price still needs to cover direct costs and produce enough contribution for overhead, owner pay and profit.

Make payment milestones objective

Good milestones describe an observable stage—such as materials ordered, rough work completed, installation completed or final acceptance—rather than vague dates that may not match progress.

Check applicable rules

Some jurisdictions or regulated trades limit deposits or impose contract requirements. Treat the business math and the legal limit as separate questions, and follow the stricter requirement that applies.
