Introduction
This Bitcoin calculator turns BTC into dollars, euros, pounds, or over 50 other currencies using live market prices. Type an amount in either box and the other one updates right away. You can also see how many satoshis you own, since one Bitcoin is made of 100 million satoshis.
The tool does more than simple math. You can check the live BTC price, market cap, 24-hour volume, and the last 7 days of price history. You can also look back and see what your money would be worth today if you had bought Bitcoin on any past date, with each step of the math shown for you.
Want to know how steady buying works? The dollar-cost averaging (DCA) calculator adds up weekly, bi-weekly, or monthly buys and shows your total BTC, your average cost, and your profit or loss. Miners can use the mining profit tool to compare daily revenue against power costs and find their break-even electricity price.
Two more parts help you read the market. The Fear and Greed Index shows if traders feel scared or greedy right now, scored from 0 to 100. The news feed lists the newest Bitcoin headlines with a quick tag for positive, negative, or neutral tone.
Everything runs in your browser and updates with real data. Pick your currency once, and every price, table, and calculator on the page switches to it.
How to use our Bitcoin Calculator
Enter a Bitcoin amount, a cash amount, or a past date, and this Bitcoin calculator shows you live BTC prices, satoshi values, past price history, profit or loss, and mining results in the currency you pick.
Bitcoin amount (BTC): Type how much Bitcoin you have or want to buy. The cash box and the satoshi count update right away.
Fiat amount: Type a cash amount instead, and the tool shows how much Bitcoin that money buys at the live BTC price.
Fiat currency: Pick your money, like USD, EUR, GBP, or INR. This changes every price, table, and calculator on the page.
Amount to convert (sub-units): Type a number to switch between Bitcoin units. It shows the same value in BTC, mBTC, µBTC, and satoshis.
Unit of that amount: Choose the unit of the number you typed, such as satoshi or BTC, so the math starts from the right size.
Purchase date: Pick the day you bought, or would have bought, Bitcoin. The tool pulls the BTC price from that date.
Investment amount: Type how much money you put in. You will see how much Bitcoin that bought and what it is worth now.
Sale / exit date: Pick the day you sold. Leave it blank to use today's Bitcoin price instead.
DCA start date: Pick the first day of your repeat buys for dollar-cost averaging.
DCA end date: Pick the last buy date, or leave it blank to use today.
Investment frequency: Choose weekly, bi-weekly, or monthly buys.
Amount per period: Type how much you spend each time. You get your total invested, total BTC, average cost, and profit or loss.
Hash rate: Type your miner's speed and pick the unit, like TH/s. This sets your share of the Bitcoin network.
Power consumption: Type how much power your miner uses and pick W, kW, MW, or hp.
Electricity price: Type what you pay for power and pick per kWh, per MWh, or per MJ.
Pool fee (%): Type the fee your mining pool takes. Then press the button to see daily, monthly, and yearly mining profit.
What Is Bitcoin?
Bitcoin (BTC) is digital money. It is not printed like cash and no bank or government controls it. Instead, thousands of computers around the world keep a shared record of every payment. That record is called the blockchain. Anyone can send Bitcoin to anyone else, at any time, without asking a bank first.
Why the Bitcoin Price Keeps Moving
Bitcoin has no fixed price. Its value comes from what buyers and sellers agree on right now. Trading never stops, so the price changes 24 hours a day, 7 days a week, on every day of the year. A move of 5% in one day is normal for Bitcoin. Big news, new rules from governments, large buyers, and simple mood swings in the market all push the price up or down.
Only 21 million Bitcoin will ever exist. About 19.9 million are already made. This limited supply is a big reason people compare Bitcoin to gold and call it "digital gold."
Satoshis: The Small Pieces of Bitcoin
You do not have to buy a whole Bitcoin. Each coin splits into 100 million tiny units called satoshis, or "sats," named after Bitcoin's unknown creator, Satoshi Nakamoto. So you can own a few dollars' worth. Here are the common units:
- 1 BTC = 1 bitcoin
- 1 mBTC (millibitcoin) = 0.001 BTC
- 1 μBTC (bit) = 0.000001 BTC
- 1 satoshi = 0.00000001 BTC
Buying All at Once vs. Buying a Bit at a Time
Some people buy Bitcoin in one big purchase. Others use dollar-cost averaging (DCA). With DCA you buy the same amount of money's worth every week, every two weeks, or every month, no matter the price. When the price is low you get more BTC. When it is high you get less. Over time this smooths out your average cost, so you do not have to guess which day is the "right" day to buy.
How Bitcoin Mining Works
Miners run special computers that guess numbers very fast to lock in new blocks of payments. About one block is found every 10 minutes, so roughly 144 blocks are found each day. The winner gets new Bitcoin plus fees. Right now the reward is 3.125 BTC per block, and it gets cut in half about every four years in an event called the halving.
Mining profit depends on three things: your machine's speed (hash rate), how much power it eats, and what you pay for electricity. Most miners join a pool so many small machines share the work and split the rewards, minus a small pool fee. Because the whole network's speed keeps rising, one machine earns a smaller slice of the rewards each year.
Fear and Greed in the Market
The Crypto Fear & Greed Index scores market mood from 0 to 100. Low scores mean fear, and many traders sell. High scores mean greed, and many traders buy. Traders watch it because crowds often get too scared near price bottoms and too excited near price tops.
Things to Keep in Mind
Bitcoin can gain or lose a lot of value fast, and past prices do not promise future gains. In many countries, selling Bitcoin for a profit counts as taxable income, so keep records of what you paid and when, then check your bill with the Income Tax Calculator. Never invest money you need for bills, build an Emergency Fund first, and store your coins in a wallet you control.
