Freelancers often think about revenue when evaluating clients, but revenue alone can be misleading. A client paying $2,000 per month can look like a great account until you divide that revenue by the total time spent working for them. For example:

Revenue: $2,000 Time spent: 45 hours Client-specific expenses: $120

That produces an effective hourly rate of about $41.77. Once you include meetings, communication, revisions, and occasional tool costs, the real hourly rate can be much lower than expected. Two clients paying the exact same amount can produce very different outcomes depending on how much time they require. I built a small free calculator that lets you enter revenue, hours worked, and expenses to quickly see the effective hourly rate for a client. It’s surprisingly helpful for understanding whether a client is actually profitable.
