Scope creep is the gradual expansion of project requirements beyond the original agreement. It is the single biggest threat to freelance profitability. Small requests -- "Can you also..." and "One more thing..." -- accumulate into hours of unpaid work that erode your effective hourly rate.
If you quoted a $10,000 project based on 100 hours of work ($100/hr effective rate), and scope creep adds 40 extra hours, your effective rate drops to $71/hr -- a 29% pay cut you did not agree to. This calculator shows you exactly how much scope creep is costing you in real time.
When scope creep occurs, present the data to your client: "We originally scoped 100 hours for this project. We are currently at 75 hours and 50% complete, which projects to 150 total hours. The additional 50 hours represent out-of-scope work from 5 change requests. I would like to discuss adjusting the project budget by $X to account for this additional scope."
Many freelancers charge a premium (10-25% above standard rate) for change orders. This serves two purposes: it compensates you for the disruption to your workflow and schedule, and it creates a financial incentive for the client to define requirements more carefully upfront.
