How to Estimate Daily BTC Earnings per TH/s

How to Estimate Daily BTC Earnings per TH/s

If you own a miner or buy hashrate, one number matters more than almost any other: how much Bitcoin you earn per terahash per second (TH/s) each day. Usually written as BTC/TH/day, it lets you compare very different miners, contracts, and pools on a level playing field. This guide explains what drives that number and how to estimate your daily earnings step by step.

What "BTC per TH per day" actually means

Your miner contributes hashrate to a pool. The pool combines everyone's hashrate, finds blocks, and pays each miner a share proportional to the work they contributed. BTC/TH/day is simply the average amount of Bitcoin one terahash of that work earns in 24 hours, after the pool's model and luck are accounted for.

Because it's normalised "per TH," you can multiply it by any machine's hashrate to project earnings — whether that's a 100 TH/s home miner or a 10,000 TH/s fleet.

What affects BTC/TH/day

• Network difficulty — the single biggest factor. As more miners join worldwide, difficulty rises and each TH/s earns slightly less BTC. It adjusts roughly every two weeks.
• Block subsidy and halvings — the fixed BTC reward per block halves about every four years. After each halving, BTC/TH/day drops sharply overnight.
• Transaction fees — when the network is busy, fees add to miner rewards and can meaningfully lift earnings.
• Pool payout model — PPS, PPS+, and FPPS distribute rewards and fees differently.
• Pool luck and fees — short-term variance and the pool's cut both affect what lands in your wallet.

Note that BTC price does not change your BTC output. A higher price makes each coin worth more in dollars, but you still mine the same number of sats per TH. Price matters for profitability, not for hashrate productivity.

A simple step-by-step estimate

1. Get the current pool rate. Most pools and dashboards publish an up-to-date BTC/TH/day figure that already bakes in difficulty and the payout model.
2. Multiply by your hashrate. Example: at 0.00000005 BTC/TH/day running 100 TH/s, gross daily earning is 0.00000005 × 100 = 0.000005 BTC.
3. Convert to USD (optional). Multiply your daily BTC by the current BTC price.
4. Subtract your costs. Deduct hosting and power. What's left is your net daily earning.

A worked example

A rig at 100 TH/s:

• Pool rate: 0.00000005 BTC/TH/day
• Gross: 0.000005 BTC/day
• At a BTC price of $80,000 → about $0.40/day gross
• Hosting/power: ~$0.15/day
• Net: ~$0.25/day

Scale that to a larger fleet and the same math holds — which is why BTC/TH/day is such a useful planning tool.

Why your real numbers will vary

Estimates are averages. Day to day, pool luck, difficulty changes, downtime, and fee spikes move actual payouts around the projection. Over weeks and months, real earnings tend to track the estimate closely.
