Bitcoin mining difficulty calculator

Models, providers and actual availability

The availability filter narrows new model choices to exact models with public fixed-price offers at the selected provider. Switch it off to explore reference specifications. Your selected scenario stays in place when a filter or provider has no match, with no matching offer clearly indicated. Reference specifications are not an inventory promise. Model selection fills hashrate and power. Provider selection fills its published default rate when one exists. Offer rates can differ; Use listing terms loads that offer rate and hardware price. You can edit all scenario values.

What changes when difficulty changes?

At a fixed hashrate and block subsidy, expected production moves inversely with difficulty. A 10% increase in difficulty reduces expected BTC by about 9.09%, not 10%. Difficulty change now applies an immediate hypothetical change. Monthly difficulty growth compounds after month one. Neither input predicts the next adjustment. The baseline uses the latest verified network difficulty and the subsidy at the next block height. Pool share difficulty is a separate threshold for submitting work to a pool. It is not the Bitcoin network difficulty used in this calculation.

• Expected BTC/day = TH/s × 10^12 × 86,400 × block subsidy / (difficulty × 2^32).
• Output is then multiplied by your delivered-output percentage and reduced by your selected pool fee. This measures delivered work, not physical hardware uptime. Transaction fees are excluded.
• Projection months contain 30 days. Estimated halvings use 210,000-block subsidy intervals and ten-minute blocks. Monthly totals are approximations, not exact payout dates.

Read the two charts separately

BTC accumulated shows production after the pool fee. Your BTC accumulation goal is independent of the BTC end price in USD. The USD chart values each month's production at the price shown for that month, then deducts hosting and the purchase price. Selecting 1, 3 or 5 years loads an editable end-price scenario of 2, 3 or 5 times today's price. These presets are not forecasts. Use today's price for a flat path, or enter a lower end price. Price moves in a straight line between the start and end. No automatic BTC sale is assumed. First break-even is the first modelled non-negative month and may be followed by a loss.

Hosting assumptions and missing data

By default, the hosting estimate scales rated power cost by your delivered-output percentage. This represents delivered work, not physical hardware uptime. For example, 90% delivered output uses 90% of the nameplate power charge. You can instead select full power for a conservative stress scenario that charges 24 hours even when output falls. Neither mode is an Open Mine invoice; actual charges follow confirmed delivery and listing terms. Running projections exclude stopped-miner storage, repairs, taxes and resale value. A missing rate or purchase price is not treated as free: affected USD results are unavailable while BTC production can remain available.

From a scenario to a specific miner

The offers below the chart match the selected exact model and provider. Compare their actual hosting rate, purchase price and provider delivery record. Open the specific offer to inspect it, then create an account if you decide to proceed. Manual specifications may differ from the model on sale. Availability and prices can change before checkout. Mining can lose money; a positive scenario does not establish future performance.

Fresh inputs without losing your scenario

The open calculator checks market inputs every 30 seconds while visible and refreshes when you revisit the page. Network difficulty uses the shared primary and reserve sources. If a refresh fails, the last verified values remain with their original check time. Delayed inputs are labelled. Your model, provider and manual assumptions stay in place. Market check times are separate from this page's editorial update date.
