Crypto Investment Calculator
Project what a crypto investment could be worth at a target price.
Please note: Cryptocurrency is highly volatile and can lose value rapidly. All prices are entered manually — no live market data is used. Nothing here is investment advice.
What the Crypto Investment Calculator does
This models a straightforward buy-and-hold: how many units your money buys at the entry price, and what those units would be worth if the price reached your target. It is a scenario tool, not a prediction.
Formula
Quantity = (Investment − Fees) ÷ Entry priceValue at target = Quantity × Target priceROI = (Value − Investment) ÷ Investment × 100
