Advanced Hash Rate Calculator
Example Data Table
| Total Hashes | Time | Workers | Rejected % | Power | Accepted Hash Rate |
|---|---|---|---|---|---|
| 1,000,000,000 | 10 seconds | 1 | 1% | 1,200 W | 99 MH/s |
| 86,400,000,000,000 | 1 day | 4 | 2% | 3,200 W | 980 MH/s |
| 9,000,000,000,000,000 | 1 hour | 6 | 0.5% | 5,800 W | 2.4875 TH/s |
Formula Used
Basic hash rate:
Hashes Per Second = Total Hashes / Time in Seconds
Accepted hash rate:
Accepted Rate = Raw Rate × (1 - Rejected Percentage / 100)
Per worker rate:
Per Worker Rate = Accepted Rate / Number of Workers
Power efficiency:
J/TH = Power Watts × 1,000,000,000,000 / Accepted Hash Rate
Expected blocks per day:
Blocks Per Day = Accepted Hash Rate × 86,400 / (Difficulty × 2³²)
Estimated daily profit:
Profit = Revenue After Pool Fee - Daily Electricity Cost

Understanding Hashes Per Second
What Hash Rate Means
Hashes per second shows how many hash attempts a device completes each second. It is a direct speed measure. Higher speed means more attempts in the same time. This matters for mining, password testing, blockchain research, and hardware comparison. The calculator starts with total hashes and elapsed time. It then converts the result into readable units. These units include H/s, KH/s, MH/s, GH/s, TH/s, PH/s, and EH/s.
Why Accepted Rate Matters
Raw hash rate is not always the final usable rate. Pools and testing systems may reject stale, duplicate, or invalid shares. The accepted rate removes that loss. This gives a cleaner view of real output. A rig with lower rejection can beat a faster rig with poor stability. That is why the rejected percentage field is important.
Power and Efficiency
Speed alone does not show the full picture. Power cost can decide whether a setup is useful. This tool calculates electricity cost per hour and per day. It also estimates hashes per watt and joules per terahash. Lower joules per terahash means better efficiency. Better efficiency can improve profit, reduce heat, and extend hardware life.
Revenue and Difficulty
Mining estimates also depend on difficulty, reward, price, and fees. Difficulty changes the chance of finding a block. Reward and price estimate possible income. Pool fees reduce gross income. The calculator combines these values into daily revenue and profit. These figures are estimates only. Real results can change with network activity, downtime, luck, and market price.
Best Use Case
Use this calculator to compare machines, settings, or mining plans. Run the same test length for each device. Keep power readings consistent. Track rejected shares carefully. Export reports when you need records. A simple saved report helps compare upgrades later. It also helps find weak workers, bad settings, and expensive power usage.
FAQs
What is hashes per second?
Hashes per second is the number of hash calculations completed every second. It measures computing speed for mining, testing, and cryptographic workloads.
How do I calculate hashes per second?
Divide total hashes by elapsed time in seconds. For example, 1,000,000 hashes in 10 seconds equals 100,000 hashes per second.
What is accepted hash rate?
Accepted hash rate is the useful hash rate after rejected or stale shares are removed. It better reflects actual pool or workload performance.
Why is my accepted rate lower than raw rate?
Rejected shares, network delay, bad tuning, overheating, or unstable hardware can reduce accepted hash rate. Lower rejection usually means better performance.
What does J/TH mean?
J/TH means joules per terahash. It measures energy efficiency. A lower value means the device uses less power for each terahash.
Can this estimate mining profit?
Yes. It estimates daily revenue using difficulty, block reward, coin price, pool fee, and power cost. Actual profit can still vary.
Why does difficulty matter?
Difficulty controls how hard it is to find a block. Higher difficulty lowers expected block share for the same hash rate.
Can I export the result?
Yes. After calculation, use the CSV or PDF buttons to download the result for reports, records, or comparisons.
