Grin Mining Calculator

Your share of the network is your share of the coins: Grin pays a flat 60 ツ per block, so a miner running x of the network's graphs per second earns x of 86,400 ツ a day. Enter your rate below.

Every figure here is an estimate at the current difficulty. Difficulty moves with the network hashrate, and block luck varies — these numbers are what your rate is worth right now, not a promise of future earnings.

Your setup

Mining hardware

Picking one fills in the hashrate and power draw for you.

Number of units

How many you run. The hashrate, power draw and hardware cost are the total for all of them — no need to multiply anything yourself.

Your hashrate (G/s)

Graphs per second, as your miner reports it — the total across every unit. Typing your own figure here switches the hardware picker to Custom and treats what you type as one unit's worth times the count.

Power draw (W, continuous)

A continuous rate, not a daily total — the total across every unit.

Electricity rate

Rough regional averages converted to USD, not quotes. Your own bill is the number that matters.

Electricity (USD / kWh)

The all-in rate off your bill — energy plus delivery, after tax.

Pool fee (%)

Solo miners leave this at 0.

Hardware cost (USD, all units)

What the hardware cost you, all units together. Type one unit's price with the count at 1 and it scales with the count from then on, the same way the hashrate and power draw do. Leave it blank to skip the payback estimate.

Hardware figures are the manufacturer's specification for the ASICs and whattomine's Cuckatoo32 table for the GPUs — both are starting points, so edit any field to match what your own miner reports. Set power draw and electricity to 0 to see gross mining income only.

Pool payout minimums, stale shares, downtime and hardware failure are not included. The break-even price covers electricity only — it is the floor below which a rig burns money every hour it runs. Paying off the hardware is the separate question answered by Pays for itself in, and that figure holds today's price and today's difficulty still for years at a time, which is not something either of them does.

How this is calculated

Your share. your G/s ÷ network G/s × 86,400 ツ. Grin's reward is flat and blocks come one a minute, so the whole network is paid exactly 86,400 ツ a day — your cut is your fraction of the hashrate.
The network figure comes from the chain, not from difficulty. This page uses the 24-hour average hashrate this explorer already computes from block headers (Δtotal_difficulty × 42 ÷ Δt ÷ 16384, the Cuckatoo32 solution rate). Being an average, it is steadier than a per-block reading.
Pool fee comes off the top; solo miners leave it at 0. Week and month are 7 and 30 days of the same daily figure.
Power cost is watts ÷ 1000 × 24 × price per kWh, and the break-even price is that cost divided by the GRIN you mine in a day.
Difficulty does not hold still. Hashrate joining the network shrinks your share, and no calculator can know that in advance — which is why every figure above is an estimate at the current difficulty.
