Time Tracking for Freelancers
Accurate time tracking is the foundation of fair freelance billing. This free time tracking calculator lets you log multiple work sessions in a day with start and end times, see your total hours, and calculate your earnings based on your hourly rate — all without any account or app required.
Why Time Tracking Matters
Most freelancers who don't track time discover they're significantly undercharging for their work. Studies show the typical knowledge worker underestimates project time by 20–40%. When you log actual time, you get an accurate picture of your effective hourly rate — and the data you need to price future projects correctly.
Billable vs Non-Billable Time
Not all time is billable. Admin tasks, invoicing, client communication, and business development are typically non-billable. Track them separately to understand your true effective rate. If you spend 30% of your week on non-billable work and charge for 30 hours, you're only earning for 21 hours of actual deliverable work.
