Insights
How these are computed- Run-rate, measured
- pending
- 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

- Lifetime earnings divided by years on Upwork. A floor on historical pace, not a forecast.
- Earnings per job
- $437
- Average contract value to date.
- Recent earnings, per Upwork
- $0
- 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
- n/a
- Total earned over billed hours. Fixed-price work inflates it; compare with the rate card.
