Most freelancers undercharge because they assume a 40-hour billable week. RateCraft calculates realistic freelance hourly, daily, and project rates using the Rule of 220 formula factoring in self-employment taxes (US, UK IR35, CA CRA, AU GST), business overhead, and 18–24 real client hours/week. Features: • 100% free with zero email signup or paywalls • Instant client-side math (zero personal data stored) • Tailored presets for devs, designers, consultants & video editors
