How to compare
A fair comparison changes one miner, not the market
Keep hashprice, Bitcoin price and your maintenance discount identical. Then enter the power, efficiency and actual price per TH for each miner. This shows whether a higher upfront price is being offset by lower daily maintenance or stronger net revenue.
Power sets the scale
More TH produces more gross BTC, but also increases both purchase price and maintenance.
Efficiency changes cost
Lower W/TH reduces electricity cost for every TH and can improve long term payback.
Price decides the tradeoff
A more efficient miner can still have a slower payback when its price per TH is much higher.
Calculation method
The same reward formula for both miners
Daily net USD = (hashprice × BTC price × TH) − [(0.05 × 24 × W/TH ÷ 1,000 + 0.0089) × TH × (1 − discount)]
Electricity is fixed at $0.05 per kWh and the service component at $0.0089 per TH each day, matching the method used by this site's daily calculator. Live hashprice is a Bitcoin network estimate, so actual pool results can differ.
Questions
Understanding the comparison
Does the highest daily reward always have the best ROI?
No. A miner can earn more each day simply because it has more TH, while also costing considerably more. ROI compares the annualized net estimate with the calculated purchase price.
Why does a lower W/TH value matter?
Electricity cost is calculated from W/TH. A lower value reduces daily maintenance for the same mining power, but you still need to compare the additional purchase price.
Is the estimated payback date guaranteed?
No. It assumes today's BTC price, hashprice, fees and discount remain unchanged. In reality these inputs can move every day, and the miner may have a resale value that this tool does not include.
