Insights
How these are computed- Run-rate, measured

- Needs two observations at least 14 days apart. Our next read of this page turns this on. Nothing is extrapolated from a single contract.
- Lifetime pace
- $116K/yr estimate
- Lifetime earnings divided by years on Upwork. A floor on historical pace, not a forecast.
- Earnings per job
- $7.1K
- Average contract value to date.
- Recent earnings, per Upwork
- $71.8K
- The "recent" figure Upwork attaches to the directory card. Upwork does not publish the window, so it is shown as its number, not ours.
- Realised hourly
- $490/hr
- Total earned over billed hours. Fixed-price work inflates it; compare with the rate card.
