What does your CPU actually earn?
Enter your hashrate. The numbers below are computed from live prices and current network difficulty, not a snapshot from last year — and they update every few minutes.

Don't know your hashrate? Install Pasiv and press start — it shows your live hashrate and what it's worth, and you can stop any time. Mining goes straight to your own wallet; Pasiv never holds funds.
A straight answer about the numbers
These are small. A laptop earns cents a day, not dollars. Three things decide whether that is worth doing:
- Is the machine already on? If it is, your marginal cost is only the extra power the CPU draws — often 30–100 W. At 30¢/kWh, 50 W is about 36¢ a day, so a fast desktop can be roughly break-even to modestly ahead, and a laptop usually is not.
- How many machines? One is a rounding error. A homelab, an office of idle desktops, or a few servers add up — and a headless node takes one line to install.
- Are you paying for power? If electricity is included in rent, or you have solar surplus, the maths changes completely.
We would rather you did this sum honestly than discovered it later. The estimates above exclude electricity and exclude the pool's own fee; Pasiv's 4% is already accounted for in what the app shows you, and the fee address is public.
