Crypto Investment Calculator

How to use the crypto investment calculator

1. Pick a coin. Bitcoin, Ethereum, Solana and nine other major cryptocurrencies are available.
2. Enter the amount you would have invested, in US dollars.
3. Choose the date you would have bought, or tap a shortcut such as 5 years ago. Earliest jumps to the first day Coinbase has a price for that coin.
4. Read the result: what the investment would be worth today, the profit or loss, and the percentage return.
5. Check the chart. It shows the value of the investment on every day since the buy date, so you can see the drops you would have had to sit through.

How the “if I had invested” result is calculated

Value today = (amount invested ÷ price on the buy date) × price now

The calculator divides your amount by the coin’s closing price on the day you chose, which gives the number of coins you would have bought. It then multiplies those coins by the latest price.

A worked example: Bitcoin closed at $435.66 on Coinbase on January 1, 2016. $1,000 would have bought about 2.2954 BTC. If Bitcoin trades at $80,000, those coins are worth about $183,629, a profit of $182,629 or +18,263%. Over ten years that is an average of roughly 68% a year. The calculator runs the same sum with the live price, so your figure will differ from this example.

What the extra numbers tell you

Average yearly return turns the total gain into a single yearly rate, the figure that lets you compare crypto with a savings account or a stock index. It appears once the holding period is a year or longer.

Highest and lowest value since buying show the journey, not only the destination. A position that ends up far ahead has usually spent months well below its previous high, and sometimes below the amount invested. If the lowest value would have made you sell, the final figure is not a return you would have earned.

Hindsight is not a forecast

Every “what if I had bought” number is known only after the fact. Past returns say nothing certain about future ones, and the largest percentage gains come from early dates when few people were buying and the coin could just as easily have failed. Use the result to understand how volatile an asset has been, not to predict what it will do next.

Buying a little every month instead of all at once? The crypto DCA calculator backtests regular purchases with the same price data. Planning a real trade? The crypto profit calculator lets you enter your own buy price, sell price and exchange fees and shows your break-even price. Buying a small amount of Bitcoin? The satoshi calculator converts sats, BTC and dollars.

Frequently asked questions

Where do the historical prices come from?

From Coinbase’s public market data. The calculator uses the daily closing price in US dollars, with days measured in UTC.

How far back can I go?

As far back as Coinbase has traded the coin. For Bitcoin that is 2015. Newer coins start later, and the date picker limits itself to the available range.

Does the result include fees or taxes?

No. It assumes you bought at the day’s closing price with no trading fee and shows the value before tax. Real results would be slightly lower.

Why is my result different from another calculator?

Prices differ a little between exchanges, and a coin can move several percent within one day. This tool uses one exchange and the closing price, so small differences from other sources are normal.

Can I use it for coins that lost value?

Yes. If the coin is worth less now than on your buy date, the result shows the loss in red.
