This calculator reconciles a cryptocurrency position using your prices and explicit fee conventions. It separates gross purchases, retained units, units sold, economic acquisition outlay and net proceeds. Quote currency is a display denomination; no exchange rates or live quotes are fetched. The original USD examples illustrate quote-paid exchange fees with zero network fees.
How the Crypto Profit Calculator works
Start with gross coins or invested cash and state whether investment includes buy fees. Quote-currency fees add cash cost; fees in another asset add the quote value you enter. Fees paid in the purchased coin reduce retained units. The same distinction applies at sale: coin fees reduce units sold, while quote and other-asset cash values reduce proceeds. Each amount enters the economics once.
Multi-Buy Average applies these rules to every fill. Each fill has its own gross quantity, price and exchange fee; its blank network fee inherits the common buy network amount, while zero overrides it. The common fee type, asset choices and valuations remain visible across modes. The result, cash comparison, profit curve, reconciliation table and exports use the same active position. Compare gross units with retained units before interpreting a blended price: cash paid per retained coin can differ from purchase trade value per gross coin. Neither calculation selects tax lots.
Why fees and break-even matter more than people think
The profit curve evaluates the same fees and fills at several exit prices, always including zero and any finite exact break-even. Its selected marker changes the active exit price, so the result and receipt update together. A no-fee reference keeps the same gross purchases and removes fees; its difference from the primary result reflects the economic fee impact, including reduced coin units.
Net proceeds can be negative when an assumed flat cash sale fee is payable at zero sale value. The checkbox can exclude hypothetical sale exchange and network fees, producing a different scenario. A 100% proportional cash sale fee or exhausted sale units gives no finite break-even. Positive tiny balances are retained in calculations even when chosen display precision is lower. Review the fee table to see which deductions remove coins and which remove cash; do not add a coin fee to outlay again. Display currency changes the label without converting any entered price.
Limits, taxes, and what this tool does not do
The receipt records economic assumptions, not a complete tax return or exchange statement. It does not select tax lots, establish holding periods, classify transactions or compute taxable fee-asset disposals. Third-asset valuations are economic costs only. Slippage, spread, staking, interest and actual execution changes are outside this model unless you incorporate them in the prices or explicit fees.
No wallet address or exchange credential is needed. A fresh visit does not store financial inputs or place them in a public URL. Remember and Forget control local persistence; Share begins with a clean link and previews optional amounts and coin label before copying. CSV, Copy, PDF and Print include the full active model at calculated precision. Older saved bytes remain untouched during migration, and known default interpretations or ambiguous numbers are disclosed for review. Check the full receipt before sending it: recipients can read any financial details you explicitly include, and a copied or downloaded record has its own privacy implications.
