Mining calculator: GPU and CPU profitability

What the mining calculator shows

For the selected hardware the FlowHash mining calculator shows the hashrate, the income in coins and in money, the electricity cost and the net profit per day, week, month and year. You can build a whole farm: add several GPUs and CPUs, set their quantity and see the combined result right away. The currency switches between hryvnia, dollar, euro, ruble and pound.

How to use the mining calculator

1. Choose a GPU or CPU from the list — or click a row in the ranking above.
2. If you have your own measurement, adjust the hashrate and power draw — the calculator will recalculate the income.
3. Enter your price per kWh to see the net profit after paying for electricity.
4. Compare the income per day, month and year and decide what is most profitable to mine.

Which GPU is best for mining in 2026

The pearlhash algorithm loads the tensor cores, so NVIDIA RTX 50 and RTX 40 cards lead: the RTX 5090, RTX 4090, RTX 5080 and RTX 4080 deliver the most TH/s. Simpler cards — the RTX 4070 and RTX 4060 — earn less, but they cost less and use little electricity. The full GPU profitability ranking with current figures is in the table above. Since FlowHash 2.0, AMD Radeon RX 6000/7000/9000 mine Pearl too — the RX 9070 XT is the fastest of them.

CPU mining: a calculator for processors

CPUs mine Monero (XMR) on the RandomX algorithm. Multi-core processors with a large L3 cache perform best — for example, AMD Ryzen 9 and Ryzen 7 X3D. A CPU earns less than a GPU, but it runs quietly in the background, and in FlowHash you can run it alongside the GPU. The CPU profitability ranking is in the table above.

Payback and electricity

Net profit = income − power draw (kW) × 24 hours × rate. For example, a 250 W GPU uses 6 kWh per day. With a high electricity rate, weak hardware can run at a loss — the calculator shows this in red. To estimate payback, divide the price of the GPU by the net profit per month.

How mining profitability is calculated

Mining income depends on three things: the hashrate of your hardware, the network difficulty and the coin price. The higher the hashrate, the larger the share of network rewards your computer receives. The FlowHash calculator takes the current difficulty and block reward straight from the Pearl and Monero networks, and prices from exchanges, so it shows an up-to-date estimate rather than year-old figures.

NVIDIA RTX GPUs mine Pearl (PRL) on the pearlhash algorithm — it loads the tensor cores, so newer RTX 40 and RTX 50 series cards deliver several times more than older ones. CPUs mine Monero (XMR) on RandomX, an algorithm designed specifically for CPUs. The FlowHash app can mine on the GPU and the CPU at the same time.

How to start earning

1. Sign up and click “Get key” in your dashboard.
2. Download FlowHash for Windows and enter the key.
3. Press one button — mining starts by itself, and income accumulates on your dashboard balance.
