Should I mine Monero 24/7 or only at night with cheaper electricity?

Mine Monero only at night if your cheaper electricity makes mining worthwhile then, but daytime electricity costs more than the coins you expect to earn. Running 24/7 makes financial sense only when the extra daytime hours also cover their added costs. If mining loses money even at your night rate, neither schedule is a good choice for profit.

Compare daytime and nighttime separately

Your main question is not “Will I earn more coins by running longer?” You usually will. It is “Will those extra coins be worth more than the extra electricity?”

Check your electricity plan for:

• The exact hours when the cheaper rate applies.
• Your full price per kilowatt-hour, or kWh, including charges that rise with usage.
• Weekend, seasonal, or peak-demand rules that could change the cost.

A kWh is the energy used by a 1,000-watt device running for one hour. Do not use your bill’s average rate if your daytime and nighttime prices differ.

Monero does not pay more simply because it is nighttime where you live. The benefit comes from cheaper power, not a special nighttime mining reward.

Measure your real cost per hour

Use a plug-in power meter if you can. Your processor’s advertised power rating is not the same as your computer’s actual electricity use.

Calculate:

Electricity cost per hour = added mining watts ÷ 1,000 × electricity price per kWh

Suppose mining adds 100 watts to a computer that would already be switched on:

• At $0.10 per kWh, mining costs $0.01 per hour.
• At $0.30 per kWh, it costs $0.03 per hour.

Those are example electricity costs, not earnings estimates.

If you would normally switch the computer off overnight, count its whole power use while mining, not just the increase over idle. Include extra cooling, too. A small overnight electricity saving can disappear if mining makes your air conditioner work harder.

Estimate what each extra hour earns

Check your actual browser mining speed, called your hashrate: the number of mining calculations your device performs each second. Measure it after the computer has warmed up, using the settings you would leave running overnight.

Browser mining can be much slower than dedicated mining software. Background tabs, sleep settings, and browser power-saving features may also interrupt it. Do not base your decision on a processor benchmark from a different setup.

Put your measured hashrate into a live Monero mining calculator. Check whether its assumptions match your setup, and account for any service or mining-pool fees. A mining pool combines miners’ work and shares rewards.

Compare estimated earnings per hour with each electricity rate:

• Above both costs: 24/7 may make sense.
• Above night cost, below day cost: choose nighttime only.
• Below both costs: stop if profit is your goal.

Leave room for changing Monero prices and network competition. A tiny estimated surplus is not dependable profit.

The bottom line

Start with a few measured overnight sessions rather than committing to 24/7. Check electricity use, accepted mining work, and the service’s minimum withdrawal amount; a displayed balance is not necessarily money you can withdraw yet.

Then add daytime hours only if they pay for themselves. You do not need to mine continuously to make nighttime mining worthwhile, and cheaper electricity alone does not guarantee a profit.
