WhatToMine is a free, browser-based hashrate calculator for people who want to estimate what mining hardware could earn before they spend money on equipment or electricity. It is aimed at home miners and small operators who compare ASIC models and want a quick sense of profitability.
There is no Windows application to install. The service works in a web browser on a Windows PC, and it also has a mobile version. Opening the site is the entire setup, which makes it useful for a first look at the numbers. This guide covers what the calculator does, how to read its results, and how to use it with caution.
What Does a Hashrate Calculator Estimate?
A hashrate calculator turns a few numbers into an estimate of mining revenue. The main inputs are your hashrate, which measures how many calculations your hardware performs per second, and the network's current difficulty, which reflects how much total computing power is competing for rewards.
The result also depends on the block reward and the price of the coin being mined. Power consumption is the other side of the equation. A machine with high hashrate but high wattage may earn less after electricity costs than a more efficient model.
Because these values change over time, the output is a snapshot rather than a forecast. Treat it as a starting point for comparison, not a fixed figure.
Who Benefits Most From a Profitability Calculator?
Home miners with one or two ASIC units often use a calculator to decide whether to keep a machine running, switch coins, or sell it. For example, someone with an older miner can enter the current power price and see whether the estimate still looks reasonable.
Buyers researching hardware also use these tools to compare models before a purchase. Entering two or three machines with the same electricity rate shows which one has the better efficiency per terahash.
Small operators may use the calculator for quick checks, while larger farms usually build their own spreadsheets or use dedicated management software alongside public estimators.
Key Terms Behind Mining Estimates
Several terms appear in every mining calculator. Hashrate is usually shown in TH/s for ASIC miners. Power efficiency is often written as J/TH, meaning joules of energy used per terahash. Lower is generally better.
Difficulty adjusts over time as more or less hardware joins the network. Developer fee is a small percentage some mining software charges, and it can reduce net output. It is not part of the calculator itself, but it matters when you compare real results with estimates.
Understanding these terms helps you read an estimate critically and notice which assumptions drive the final number.

- An internet connection
How to use Hashrate calculators: WhatToMine
Using WhatToMine is straightforward once you know which numbers to enter. Gather your hardware specs and your electricity rate before you start, so the estimate reflects your actual situation.
- Open the calculator on the official website in your browser.
- Enter the hashrate and power consumption of the miner you want to test.
- Add your electricity cost per kilowatt-hour so the result reflects operating expenses.
- Review the estimated output and compare it with other machines or settings.
- Change one variable at a time, such as electricity price, to see how sensitive the result is.
Pros & cons
- Free to use with no account needed
- Nothing to install on a Windows PC
- Works in any modern browser and on mobile
- Useful for comparing hardware before buying
- It is a web service only, not a Windows application
- Requires an internet connection
- Estimates change as network conditions change
- Does not manage or configure your miner
Is Hashrate calculators: WhatToMine safe?
WhatToMine is a website, so there is no installer to check with a SHA-256 checksum or signature. To stay safe, open the address whattomine.com directly and ignore search ads or pages that claim to offer a Windows version. Search results can include look-alike domains, so check the address carefully.
Never enter a seed phrase, private key or wallet password into any calculator or third-party website. A profitability tool has no reason to ask for them. Remember that the results are estimates, not guaranteed earnings. Check the official website for the latest information before making hardware decisions.
- Official source only. Download from whattomine.com. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
WhatToMine focuses on estimating profitability, while the other tools in this category usually manage hardware. Braiins Toolbox and BTC Tools are utilities for working with specific ASIC families, and Foreman is aimed at monitoring mining farms. WhatsMinerTool is designed for MicroBT machines.
If you are deciding what to buy or whether a machine is worth running, a calculator like WhatToMine is the right starting point. If you already own hardware and need to configure or monitor it, a management tool is more useful. Many miners use both: a calculator to plan and a management utility to operate.

Frequently asked questions
No, WhatToMine does not have a Windows application. It is a web service, so you open whattomine.com in a browser on your Windows PC. There is nothing to download or install, which also means there is no separate program to keep updated on your computer.
Yes, WhatToMine is free. You can open the calculator, enter your hardware details, and review the estimates without paying a fee for the basic profitability tool. Free access does not mean the estimates are guaranteed, so compare results carefully before making any purchase.
WhatToMine is a web calculator that does not ask for wallet keys or seed phrases. To stay safe, type the official address yourself and avoid look-alike sites. Never share private keys or recovery phrases with any profitability tool, and treat its output as an estimate rather than a guaranteed result.
WhatToMine estimates are only as accurate as the inputs you provide and the network conditions at the time you check. Difficulty, coin prices and electricity rates change frequently. Use the calculator to compare options side by side rather than as an exact forecast of future income.
Yes, WhatToMine can be used on a mobile device through a browser. The layout works without installing an app. Your inputs and results depend on the same web service, so the numbers should match what you see on a desktop browser.
A hashrate calculator is a tool that estimates mining revenue based on hardware performance, power use and network conditions. You enter your machine's hashrate and electricity cost, and it shows an approximate return. It helps you compare hardware but does not control or configure any miner.
Verdict
WhatToMine is a practical choice for people who want a free, quick way to estimate mining profitability before buying or running ASIC hardware. It suits home miners and buyers comparing models. Because it is a web service with no Windows installer, it is not the right tool for managing or updating a miner. Use it for planning, check the official website for current details, and treat every estimate as a starting point rather than a promise.
