Estimates, not promises. Results vary with demand, your reliability score, internet connection and hardware. Rental prices are in USD and converted at the ECB reference rate. See the methodology for every formula and source.
Why is it less than the claims I've seen?
Most earnings claims quote the hourly rental price as if the card were rented around the clock. You are only paid while someone rents it, and new hosts are often skipped until they build a reliability record.
Electricity is paid whenever the machine is on, rented or not, and for the whole PC, not just the graphics card. Above the break-even price shown in each card, hosting costs more than it earns.

Every figure above comes from one of these. Figures marked “not yet verified” were taken from search summaries and are being checked against the original page.
Host fee removed and replaced by an internal surcharge; "the prices hosts set will be the prices they earn". Vast does not say how large the surcharge is.
Graphics card power 350 W for the RTX 3090 (450 W for the 3090 Ti).
Total graphics power 450 W.
Total graphics power 575 W.
About 18 W at idle with one monitor, about 26 W with two. Not a measurement of ours.
Idle: RTX 5090 about 30 W, RTX 4090 about 22 W. The page blocks automated access and the figures are in charts, so they were not confirmed.

Qualitative only: a card earns nothing while unrented, and hosts without a reliability record are skipped. It gives no utilization figure.
