What is Crypto Calc

Crypto Calc is a free set of tools that helps anyone interested in crypto run the basic numbers quickly and easily: average cost, profit/return, breakeven, and target price. It transparently shows, with formulas, your dollar-cost-average buy price, your fee-adjusted return, the new average and breakeven price after averaging down, and the sell price needed to reach a target return.

Our principles

• Formulas shown — Each calculator clearly shows the formula it uses (weighted average, breakeven price, target price, and so on) in the body text.
• Fees included — Enter buy and sell trading fees to estimate profit close to reality.
• No personal data — Inputs are processed only in your browser and are never sent to or stored on a server.
• Clear disclaimer — We make it clear that every result is a simple estimate for reference and entertainment only.

How the math works

Crypto Calc uses universal formulas based on standard exchange practice. Average price is a weighted average (total cost / total quantity), breakeven price is average price x (1 + fee rate) / (1 - fee rate), and return is net profit / cost basis x 100. Trading fee rates change often by exchange, order type, and promotion, so check your exchange's fee schedule and enter the exact rate.

Disclaimer

Every result from Crypto Calc is a reference estimate based on your inputs and the published formulas. Crypto prices are highly volatile, and actual fill prices can differ due to the order book, slippage, and taxes. This service does not recommend buying or selling any asset and does not guarantee returns. You are solely responsible for your investment decisions and their outcomes.
