Why most freelancers undercharge
People tend to take their desired salary and divide by 40 hours a week — forgetting that 25-40% of their time is non-billable (invoicing, marketing, admin), plus taxes, benefits, and business expenses. We work backwards from your desired take-home to a rate that actually gets you there.
