Why is my pool showing a different estimated income than the calculator?

Your pool and your mining calculator may show different estimated income because they use different inputs, time periods, or fee assumptions. Neither number is a promise: to compare them fairly, you need to check what each estimate measures and how it was calculated.

Your pool measures work differently

A calculator usually starts with the hashrate you enter: how many mining calculations your device performs each second. Your pool—a service that combines miners’ work and shares rewards—often estimates your hashrate from the work it actually receives.

You send that work as shares, which are proofs that your miner is contributing. Shares arrive at uneven intervals, so your pool’s estimate can jump around even when your device runs steadily.

Check whether you are comparing:

• Your miner’s current speed with your pool’s daily average.
• One device’s speed with the total from all your devices.
• A short burst of mining with an estimate that assumes 24 hours of continuous operation.

This matters especially when you mine in a browser. Closing your tab, putting your computer to sleep, or browser limits on background activity can reduce the work your pool receives. Shares that arrive too late or fail validation may also go unpaid.

The calculator may use different network numbers

Mining estimates depend on network difficulty, which describes how hard it is to find a valid Monero block. Monero adjusts difficulty every block, roughly every two minutes.

Your calculator might use the latest difficulty, while your pool uses a recent average—or the other way around. Both estimates can be reasonable while still disagreeing.

Reward assumptions also matter. Monero’s ongoing base reward is 0.6 XMR per block, with transaction fees added. One estimate may include recent transaction fees; another may count only the base reward.

If the difference appears only in dollars or another currency, compare the estimates in XMR first. The services may use different exchange prices or update prices at different times.

Pool luck and payout rules can change the picture

Some pool dashboards project income from recent actual results. Others calculate a theoretical estimate from your hashrate and network difficulty.

Actual results depend partly on pool luck: a pool can find more or fewer blocks than expected during a particular period. A lucky day can make a recent-results estimate look unusually high. An unlucky day can do the opposite.

Your pool’s reward system can add another difference. For example, PPLNS, or “pay per last N shares,” divides rewards using a window of recently submitted shares. If you have just started mining, your participation in that window may still be building.

Also separate these figures:

• Estimated income: a projection of what you might earn.
• Pending balance: rewards awaiting confirmation or settlement.
• Paid balance: funds already sent to your wallet.

A minimum payout threshold delays payment; it does not, by itself, reduce your estimated earnings.

Make a like-for-like comparison

Use your pool’s longer-term accepted hashrate in the calculator, ideally from a day when your mining schedule was typical.

Then match the pool fee, operating hours, network assumptions, and currency price. Check whether the calculator subtracts electricity costs while the pool shows rewards before costs.

If a large gap remains, read your pool’s estimate description and check for rejected shares or missing mining time. Treat unexplained, unusually high estimates cautiously.

The bottom line

Compare the same hashrate, period, fees, and XMR units first. Your pool reflects the work it sees; your calculator reflects the assumptions you give it.
