What If I Had Invested in Crypto?

To see what a past crypto investment would be worth today, divide the amount you invested by the coin's price on your purchase date, then multiply by today's price. The calculator above does this automatically for 10,000+ coins using historical CoinGecko prices. Pick a coin, enter an amount and a date, and it shows what your investment is worth today and your ROI.

It works for any coin with price history: Bitcoin, Ethereum, Solana, Polkadot, Chainlink, Aptos and smaller altcoins alike.

How Crypto ROI Is Calculated

Worked Example: $100 in Solana in 2021

• Price of SOL on 01/01/2021: $1.52
• Amount invested: $100
• Price of SOL on 10/05/2022: $63.60

1. Coins bought: $100 ÷ $1.52 = 65.79 SOL
2. Value on 10/05/2022: 65.79 × $63.60 = $4,184.24
3. ROI: ($4,184.24 − $100) ÷ $100 × 100% = 4,084% (about a 42x)

Run the same numbers with today's price in the calculator to see where that position stands now.

How to Use the Crypto Investment Calculator

1. Choose the cryptocurrency you bought, or want to test, from the search box.
2. Enter the investment amount in your currency.
3. Pick the purchase date. Any date the coin was trading works.
4. Read the results: the current value of your investment and your ROI %.

What This Calculator Is Good For

• "What if" checks: see what $1,000 in Bitcoin five years ago would be worth today.
• Tracking a real purchase: get your current return without logging into an exchange.
• Comparing coins: run the same amount and date for two coins and compare the ROI.

Related Crypto Calculators

This calculator looks backward at a real price history. For forward-looking scenarios, use one of these:

• Expecting a coin to grow to a certain valuation? The crypto market cap calculator shows what your coin would be worth at another coin's market cap, for example Solana at Ethereum's.
• Trading meme coins or new launches? The meme coin profit calculator works from entry and exit market cap instead of price.
• Earning yield on your coins? The crypto staking calculator projects daily, monthly and yearly rewards from an APR.
• Planning a leveraged trade? The position size calculator tells you how much to buy so a stop-loss hit only costs a set percentage of your account.

Frequently Asked Questions

Does the calculator include trading fees?

No. It uses market prices only. Exchange fees, spreads and taxes will reduce your real return slightly.

What if I bought the same coin several times?

Run each purchase separately and add up the results, or use your average buy price and total amount to estimate the overall return.

Is past performance a guide to future returns?

No. A coin that went up 40x in one cycle can fall 90% in the next. Use the result as a historical record, not a forecast.
