How to estimate project hours

Most underpriced projects start with one optimistic number. Instead of asking “how long will this take?”, estimate each stage on its own: discovery and planning, the primary production work, meetings and messages, admin and file handling, testing and review, then delivery and handoff.

Estimating in pieces surfaces the hours nobody bills for — the call that runs long, the file renaming, the export that fails twice. Add your own rows for anything unusual, like a shoot day or a site visit, and you have an estimate you can defend.

Why flat-fee projects need a contingency buffer

On an hourly contract, extra time is simply extra income. On a flat fee, extra time comes straight out of your pocket. The contingency buffer is the premium you charge for carrying that risk on the client’s behalf.

A 15% buffer on a 40-hour project covers six hours of surprises. That’s usually the difference between a project that earned your rate and one that quietly didn’t.

Hourly pricing versus flat project pricing

Hourly billing protects you and worries the client, because they can’t predict the total. A flat fee reassures the client and shifts the risk to you. Neither is automatically better — what matters is that the flat fee is calculated from hours rather than guessed at.

• Hourly suits open-ended work, retainers and ongoing support.
• Flat fees suit clearly defined deliverables with a known finish line.
• Flat fees also reward you for getting faster, because your effective hourly rate rises as your process improves.

How to control revisions and scope creep

Name a number of revision rounds in writing, say how long each round takes, and state what counts as a new request rather than a revision. “Two rounds of consolidated feedback” is enforceable; “revisions until happy” is not.

A scope-creep allowance of 10–20% absorbs the small extras that are easier to do than argue about. Anything larger should be quoted separately — which is exactly what the client quote note says.

How deposits and payment milestones work

A deposit does two jobs: it funds the expenses you pay before you get paid, and it proves the client is committed. 50% up front and 50% on delivery is the most common split for project work.

On longer projects, break the balance into milestones tied to deliverables rather than dates — for example a third at approval of the concept, a third at first draft, and the rest at handoff. That keeps your cash flow moving with the work.

A worked project-pricing example

Take the sample project: a $75 desired rate, a $50 minimum, and 32 estimated hours across planning, production, meetings, admin, testing and delivery. Two revision rounds at two hours each add 4 hours, giving 36 initial hours. A 10% scope-creep allowance adds 3.6 hours, and a Moderate complexity adjustment of 10% brings the total to about 43.6 hours.

At $75 an hour that’s roughly $3,270 of labor, plus $275 of expenses for software, outsourcing and licensing — about $3,545. A 15% contingency adds roughly $532, and 10% profit adds about $408, landing near a $4,485 flat fee. The deposit is around $2,243, and the effective hourly rate stays comfortably above the $50 floor.

Common flat-fee pricing mistakes

• Estimating only the visible production work and ignoring calls, admin and delivery.
• Leaving out a contingency buffer on an unfamiliar type of project.
• Offering unlimited revisions, or not defining what a revision is.
• Absorbing licensing, stock or outsourcing costs into your own margin.
• Discounting before calculating the full profitable price.
• Starting work without a deposit or a written scope.
• Quoting one number with no alternative, so the client can only say yes or no.
