How It Works

USD Value = Coin Amount × Price Per Coin. Coins Per Dollar = 1 ÷ Price Per Coin. Both are calculated simultaneously from the same two inputs. For example, 2.5 ETH at $3,200 per ETH: USD Value = 2.5 × $3,200 = $8,000. Coins Per Dollar = 1 ÷ $3,200 = 0.0003125 ETH per dollar. The USD value is rounded to two decimal places (cent precision). Coins Per Dollar is rounded to ten decimal places, which is necessary for high-priced assets — at $65,000 per BTC, one dollar buys 0.0000153846 BTC, a number requiring ten decimal places to represent meaningfully. This tool also handles the reverse conversion. To find how many coins a dollar amount buys, divide that amount by the price per coin. For example, $5,000 ÷ $3,200 = 1.5625 ETH. No live price data is fetched; the price is entered manually, making the tool equally useful for real-time checks, historical tax records, and hypothetical scenario planning. For current prices, check CoinGecko, CoinMarketCap, or your exchange before entering the value.

Examples

Half a Bitcoin
0.5 BTC at a price of $65,000 per coin.
Result: $32,500 USD. One dollar buys approximately 0.0000154 BTC at this price.
Ethereum Holdings
3.5 ETH at $3,500 per coin.
Result: $12,250 USD. One dollar buys approximately 0.000286 ETH.
Low-Priced Altcoin
10,000 tokens of a $0.15 altcoin — a common small-cap holding.
Result: $1,500 USD. One dollar buys approximately 6.667 tokens — typical fractional scale for low-priced assets.

Frequently Asked Questions

Where do I get the current price?
Check CoinGecko, CoinMarketCap, Coinbase, Binance, or any major exchange for real-time prices. Prices vary slightly between exchanges due to liquidity differences, but the variation is usually under 1% for major assets. For tax or accounting purposes, document which price source you used and at what timestamp, as the IRS and most tax authorities require defensible fair-market-value figures for each transaction date.
Can I convert fractions of a coin?
Yes — Bitcoin is divisible to 8 decimal places, with the smallest unit being one satoshi (0.00000001 BTC). Ethereum is similarly divisible to 18 decimal places. Enter values like 0.00001 BTC or 0.0005 ETH directly in the coin amount field. The calculator handles any positive decimal value, so you can work with satoshi-level amounts or large whole-coin positions with equal precision.
Can I go from USD to crypto instead?
Yes — divide your USD amount by the price per coin to find how many coins it buys. For example, $1,000 ÷ $65,000 = 0.01538 BTC. Alternatively, the Coins Per Dollar output directly answers the question for a single dollar, and you can multiply that by any dollar amount. The same arithmetic works in both directions: multiplying coins by price gives USD, and dividing USD by price gives coins.
