What could your Bitcoin miner return over time?
Model how much BTC your miner may produce, what that Bitcoin could be worth later, and the resulting return after hardware and hosting costs.
How this calculator works
The model estimates BTC production from an Antminer S21 XP reference rate, reduces future output using your selected annual decline, and values all mined Bitcoin at the modeled price for each point in time. Cash outlay includes the miner purchase and cumulative hosting costs.
Mining setup
Start with your miner count, hardware cost, hosting cost, and the current Bitcoin price.
Growth assumptions
Adjust the timeline, modeled Bitcoin growth, and expected decline in mining output.
Projected mining return after hardware and hosting costs
Modeled value and cumulative cost
Track the projected value of held mined Bitcoin against total hardware and hosting outlay over time.

Methodology & assumptions
The model starts with a reference production rate of 0.0001341 BTC per day for one Antminer S21 XP, based on Abundant Mines' public August 2026 example, then reduces future BTC production using the selected annual mining-output decline.
Total cash outlay equals hardware purchase cost plus monthly hosting for the selected period. All mined BTC is assumed to be held throughout the timeline.
At each month, projected BTC value equals cumulative BTC produced multiplied by the modeled Bitcoin price for that month. The ending estimated profit equals ending projected BTC value minus total cash outlay. Estimated ROI equals estimated profit divided by total cash outlay.
The mining-output decline is a simplified proxy for changing network difficulty, global hashrate, block rewards, transaction fees, uptime, and other mining conditions.
