Understanding Graphics Card Hash Rate and Profitability
When evaluating graphics cards (GPUs) for cryptocurrency mining, the raw technical specifications of the card—such as core clock speed or memory size—are secondary to its Hash Rate. This calculator helps you translate that technical metric into real-world economic data.
What is Hash Rate?
Hash rate is a measure of the computational power your graphics card contributes to a blockchain network. It represents the number of guesses (hashes) your GPU can make per second in an attempt to solve the cryptographic puzzle required to mine a block.
MH/s (Megahashes per second): Millions of hashes per second. This is the standard unit for most consumer GPUs mining algorithms like Etchash or KawPow.
Efficiency (MH/W): This metric defines how many hashes you get for every Watt of electricity consumed. A higher efficiency score means your card runs cooler and costs less to operate.
Why Power Consumption (Watts) Matters
The biggest ongoing cost in mining is electricity. A high hash rate is meaningless if the electricity cost to run the card exceeds the value of the crypto earned. This calculator determines your Net Profit by subtracting your daily electricity expenditure (based on your local $/kWh rate) from your gross mining revenue.
Calculating ROI (Return on Investment)
ROI, or the "Break-even Point," tells you how long it will take to pay off the initial cost of your hardware using your mining profits.
Formula: Hardware Cost / Daily Net Profit = Days to Break Even.
In a volatile market, aim for a lower ROI period (typically under 200 days) to mitigate risk. If the calculator shows "Never," your electricity costs likely outweigh your earnings, or the hardware is too expensive for its current output.
Optimizing Your Hash Rate
To get the most accurate results from this calculator, ensure you are inputting the "tuned" values for your GPU. Most miners under-volt their cards (lower the power limit) and overclock the memory to increase Hash Rate while simultaneously decreasing Power Consumption, drastically improving the Efficiency score calculated above.
