Manual estimate
Calculator
Works without a wallet, an RPC or any data source. Every number below is yours; nothing is fetched. Results are labelled as a manual estimate so they are never mistaken for verified market data.
Enter a buy price, a sell price and a starting amount.
Manual estimate — based on your inputs. Not verified market data.
Accounting convention. Buy fee = starting amount × buy fee %, deducted before buying; asset quantity = (starting amount − buy fee) ÷ buy price; sell fee = gross proceeds × sell fee %; net result = proceeds after fee − starting amount − gas − additional costs. Break-even is the sell price where the net result is exactly zero (rounded up). Percentages are percent, not fractions: 0.3 means 0.3 %. Every step rounds down.
