Why does my actual yield fall over time?

Because the network hashrate keeps rising while yours stays fixed, so your share shrinks. Difficulty adjustments enforce this.

Crypto Mining Profitability Calculator

Mining revenue against electricity and hardware. Every input except your own hashrate moves against you over time: network hashrate rises, rewards halve, and hardware obsoletes.

Also called: bitcoin mining profitability, mining roi calculator.

Daily profit

₹77

₹77 a day: ₹701 of revenue less ₹624 of electricity. Payback on the hardware is 5,825.2 days, and electricity is 88.98% of revenue.

How this is calculated

An estimate, not an offer or a guarantee. Projected returns assume the rate you entered holds for the whole term, which no market does.

Method and background

How this is calculated

Your share of the network hashrate determines your share of the blocks. Revenue is that share of the daily reward at the current coin price, and electricity is the power draw times the tariff. The break-even coin price is the number worth watching, because network hashrate rises continuously and the block reward halves on schedule, so today's payback period assumes conditions that will not hold.

Method and limits

What it assumes

Constant network hashrate, coin price and difficulty, none of which are constant.

What it deliberately does not model

Difficulty rises as more miners join, so the coin yield falls over time from the same hardware.
Pool fees, cooling and downtime are not included and are all material.
This is a mechanical projection, not a recommendation to mine.
