Why "Rate Γ Hours" Alone Underprices Your Work
The most common freelance pricing mistake is stopping at quote = hourly rate Γ estimated hours. Real projects almost always include revision requests, extra communication, and surprises, so this calculator adds two layers. β Revision/risk buffer: multiplies estimated hours by a cushion (typically 15β30%). β‘ Margin: covers business overhead β equipment, software, insurance, unbilled gaps between projects β plus profit (typically 10β30%). For example, at $50/hour for a 40-hour project, base labor is $2,000; a 20% buffer brings it to $2,400; a 15% margin makes the final quote $2,760. That looks 38% above base, but once two revision rounds and extra meetings land, this is what actually preserves your intended hourly rate.
